&nbsp;CADR shows the speed at which an air purifier can clean your room’s air. It represents the volume of filtered air the system delivers over a specific period. This was developed by the Association of Home Appliance Manufacturers (AHAM) in the early 1980s to standardise the performance of air purifiers across all types and categories.<a target="_blank" rel="noopener noreferrer" href="https://www.aham.org/AHAM/Standard_Chart_Page.aspx">¹</a> &nbsp;In this article, we explain what CADR is and how it can help in choosing an air purifier for your needs.<h2> How CADR is Measured&nbsp; &nbsp;</h2>According to AHAM, the CADR rating for air purifiers signals the effectiveness of removing different particle sizes. During the test, the air purifier run on the highest fan speed. Each particle is measured and given its own CADR rating. Each <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air purification system</a> lists these CADR values:&nbsp;<ul><li>Dust: For visible particles such as dirt and lint.</li><li>Pollens: For allergens.</li><li>Smoke: For fine particles in the air from cooking, traffic, or burning.</li><li>PM 2.5: PM 2.5 CADR is a measurement of the particles that are smaller than 2.5 microns. &nbsp;</li></ul>In the US, the CADR is measured in CFM (cubic feet per minute). In Asia, it is measured in cubic meters per hour (m3/h), 0.59 cu ft/min is equivalent to one cubic metre per hour, or 1 CFM = 1.69 m3/h.<a target="_blank" rel="noopener noreferrer" href="https://ahamverifide.org/ahams-air-filtrations-standards%e2%80%a8/https:/ahamverifide.org/wp-content/uploads/2021/11/White-Paper-Portable-Air-Cleaners-and-AIr-Changes-per-Hour-FINAL-00106301.pdfhttps:/www.epa.gov/pm-pollution/particulate-matter-pm-basics#:~:text=PM10%20:%20inhalable%20particles%2C%20with,than%20the%20largest%20fine%20particle">²</a>&nbsp;<h2>How to Match CADR to Your Room Size</h2> Matching the right CADR starts with your room’s size and how quickly the air needs to be cleaned. Use the steps below to choose the <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">best air purifier</a> for your space.&nbsp;<ul><li><h3>Step 1: Measure your room &nbsp;</h3>Multiply length × width × height to get the room volume. &nbsp;</li><li><h3>Step 2: Know the ideal air changes &nbsp;</h3>Most homes need 4 to 5 air changes per hour (ACH) for effective purification. &nbsp;</li><li><h3>Step 3: Match room size with CADR &nbsp;</h3>Select a purifier with a CADR sufficient to filter your room’s air volume according to the recommended air changes per hour (ACH). &nbsp;</li><li><h3>Step 4: Adjust by room type &nbsp;</h3>Bedrooms need a lower CADR than living rooms or open areas with more people. &nbsp;</li><li><h3>Step 5: Avoid under- and over-sizing &nbsp;</h3>Low CADR cleans too slowly. Very high CADR may increase noise and power use. Slightly higher-than-minimum CADR works better for Indian pollution conditions. &nbsp;</li></ul>For medium-sized rooms up to 310 sq. ft., the <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/dp/GAPDF230KJB000/forbes-230-surround-360-air-purifier-true-hepa-h13-filter-covers-up-to-310-sq-ft-1-5-2-yr-filter-life">Forbes 230 Surround 360° Air Purifier</a> is a suitable choice. It uses Surround 360° Air Intake Technology and a 4-stage filtration system with a True HEPA H13 filter to remove 99.97% of fine particles, dust, and allergens. The activated carbon layer also helps reduce odours and VOCs. With a long filter life of up to 1.5–2 years, quiet sleep mode, and timer settings, it delivers reliable indoor air cleaning with low upkeep, making it a practical choice for bedrooms, studies, or compact living areas. &nbsp;<h2>Misconceptions About CADR</h2> Consumers often misinterpret what CADR really means. Here are the most prevalent misconceptions: &nbsp;<ul><li><h3>Higher CADR means better filtration. &nbsp;</h3>CADR specifically measures how fast air is cleaned, not how thoroughly pollutants are removed. Filter quality and sealing still matter. &nbsp;</li><li><h3>Room size labels are reliable benchmarks. &nbsp;</h3>Room size claims differ by brand and testing method. CADR provides a consistent metric for comparison.&nbsp; &nbsp;</li><li><h3>Larger units are always superior. &nbsp;</h3>Physical size or wattage does not guarantee higher airflow efficiency or purification speed.&nbsp; &nbsp;</li><li><h3>One CADR rating is sufficient. &nbsp;</h3>Separate CADR ratings exist for dust, pollen, and smoke. It’s important to assess the different scores when choosing an air purifier for your home.</li></ul>&nbsp;<h2>Key Factors to Consider When Choosing an Air Purifier &nbsp;</h2>CADR should not be the sole criterion for choosing an air purifier. Here are the key factors to consider: &nbsp;<ul><li>Filter Type: True HEPA filters capture fine particles like dust, pollen, and microbes. Activated carbon filters help remove odours, smoke, and VOCs. &nbsp;</li><li>Room Size Coverage: Ensure the purifier can handle the square footage of your room for consistent purification. &nbsp;</li><li>Noise Levels: Review the decibel rating to ensure the purifier operates quietly, particularly in bedrooms or study spaces. &nbsp;</li><li>Power Consumption: Consider energy efficiency for long-term use. &nbsp;</li><li>Maintenance &amp; Filter Life: Check how frequently the filters require replacement and consider the associated costs. &nbsp;</li><li>Price: Compare models based on <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air purifier price</a> to balance performance, features, and budget without compromising quality. &nbsp;</li><li>Additional Features: Timer settings, sleep mode, and air quality indicators can enhance convenience and usability. &nbsp;</li></ul>These factors help you pick a purifier that suits your space, lifestyle, and indoor air quality needs.

What is CADR? An Important Metric You Need to Know Before Buying an Air Purifier

&nbsp;Delhi’s air pollution is no longer a seasonal problem. For many residents, <a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8509169/">constant coughing, breathing difficulties, irritated eyes, and recurring infections</a> have become part of everyday life. Stepping outside feels risky on most days, even with an N95 mask, and staying indoors no longer guarantees clean air. <a target="_blank" rel="noopener noreferrer" href="https://healthpolicy-watch.news/indias-air-quality-index-improves-but-delhi-remains-worlds-worst-polluted-city/">As pollution levels continue to rise year after year</a>, the strain on respiratory health has become impossible to overlook.&nbsp;&nbsp;This concern is backed by hard data. According to I<a target="_blank" rel="noopener noreferrer" href="https://www.iqair.com/us/world-most-polluted-cities">QAir’s 2024 report</a>, Delhi ranked among the world’s most polluted cities in 2023, a trend that carried into the winter of 2024-25. During this period, the city recorded some of India’s highest average PM2.5 levels, far exceeding safe limits.&nbsp;But beyond the numbers and rankings, the real impact of air pollution is being felt in homes, offices, and lungs across the city, raising urgent questions about how people can protect their health in an environment that’s growing harder to breathe in.&nbsp;<h2>The Growing Problem of Air Pollution in Delhi</h2>&nbsp;Delhi has long struggled with air pollution, with the AQI (Air Quality Index) frequently exceeding 400, which is classified as severely hazardous for everyone. Multiple everyday sources contribute to this persistent problem: ·&nbsp;&nbsp;<ul><li><a target="_blank" rel="noopener noreferrer" href="https://www.who.int/news-room/fact-sheets/detail/ambient-(outdoor)-air-quality-and-health">Vehicular emissions:</a> Heavy traffic releases fine particles and harmful gases into the air.</li><li><a target="_blank" rel="noopener noreferrer" href="https://airly.org/en/how-do-factories-cause-air-pollution/">Industrial activity</a>: Factory emissions add pollutants that degrade air quality.&nbsp;</li><li><a target="_blank" rel="noopener noreferrer" href="https://www.sciencedirect.com/science/article/abs/pii/S004565352203483X">Construction dust</a>: Ongoing construction generates large amounts of fine dust that spreads easily. ·&nbsp;</li><li><a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6427124/">Seasonal biomass burning</a>: Crop residue burning during certain months worsens pollution levels.&nbsp;</li><li><a target="_blank" rel="noopener noreferrer" href="https://www.medanta.org/patient-education-blog/why-air-pollution-gets-worse-in-winter">Winter weather conditions</a>: Low wind speeds and temperature inversion trap pollutants near the ground, intensifying smog.</li></ul>&nbsp;While outdoor pollution is visible and widely discussed, its impact indoors often goes unnoticed. Fine particulate matter, especially PM2.5, is microscopic and easily enters homes through windows, doors, and ventilation systems. This means indoor air in densely populated areas can be nearly as polluted as outdoor air, making indoor air management just as crucial as taking outdoor precautions.&nbsp;<h2>Why Indoor Air is an Overlooked Health Risk</h2>&nbsp;Many people assume that staying indoors, keeping doors locked, windows shut, and limiting outdoor exposure is enough to protect against polluted air. However, <a target="_blank" rel="noopener noreferrer" href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2025.1626827/full">studies</a> show that indoor air quality in Delhi homes can still be severely compromised. Long-term exposure to airborne pollutants, especially in poorly ventilated spaces, allows harmful particles such as PM2.5, dust, and chemical residues to accumulate <a target="_blank" rel="noopener noreferrer" href="https://www.epa.gov/indoor-air-quality-iaq/introduction-indoor-air-quality">indoors</a> over time. As these pollutants circulate and settle, indoor air quality gradually worsens, increasing health risks even for those who remain indoors.&nbsp;&nbsp;This pictures the importance of using <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">an air purifier at home</a>. Without active filtration, indoor air continues to carry dust, smoke, allergens, bacteria, and other pollutants that can directly impact health. A reliable room air purifier helps reduce this exposure by continuously removing harmful particles and keeping indoor air cleaner.&nbsp;<h2>The Immediate Effects of Air Pollution on Human Health</h2>&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://www.who.int/teams/environment-climate-change-and-health/air-quality-energy-and-health/health-impacts">Air pollution</a> can have noticeable impacts on human health even with short-term exposure. Common immediate effects include:&nbsp;<ul><li>Persistent coughing and throat irritation</li><li>Burning, watery, or itchy eyes</li><li>Headaches, dizziness, and fatigue</li><li>Shortness of breath or mild chest tightness</li><li>Sneezing or nasal congestion</li><li>Irritated skin in sensitive individuals</li></ul>&nbsp;Children, the elderly, and people with asthma or allergies are particularly vulnerable to these causes of pollution. These <a target="_blank" rel="noopener noreferrer" href="https://www.hopkinsmedicine.org/health/wellness-and-prevention/air-quality-and-health#:~:text=Unhealthy%20Air's%20Impact%20on%20Health,tightness%20or%20shortness%20of%20breath">symptoms</a> occur as the body reacts to irritation and inflammation caused by inhaling polluted air.&nbsp;<h2>Long-Term Health Impacts of Air Pollution</h2>&nbsp;Beyond immediate symptoms, the long-term impacts of air pollution can be far more serious. Fine particulate matter like <a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4740125/">PM2.5</a> can penetrate deep into the lungs and even enter the bloodstream. Prolonged exposure increases the risk of <a target="_blank" rel="noopener noreferrer" href="https://www.who.int/teams/environment-climate-change-and-health/air-quality-energy-and-health/health-impacts">chronic health issues</a>, including:&nbsp;<ul><li>Stroke</li><li>Ischaemic heart disease</li><li>Chronic obstructive pulmonary disease (COPD)</li><li>Lung cancer</li><li>Pneumonia</li><li>Cataracts&nbsp;</li></ul>&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4740125/">Research</a> shows that people living in highly polluted cities like Delhi face higher risks of asthma, respiratory inflammation, reduced lung function, and even cancer. These long-term effects make clean indoor air a necessity rather than a luxury.&nbsp;This is where a HEPA air purifier becomes essential. True HEPA filters can capture up to 99.97% of airborne particles, including PM2.5, dust, smoke, pollen, and microbes. By continuously removing these fine particles from indoor air, a HEPA air purifier helps reduce long-term exposure and supports healthier breathing indoors.&nbsp;<h2>Who Is Most at Risk?</h2>&nbsp;While air pollution affects everyone, certain <a target="_blank" rel="noopener noreferrer" href="https://www.cpcb.nic.in/uploads/healthreports/Study-Air-Quality-health-effects_Children-2012.pdf">groups</a> are more vulnerable:&nbsp;<ul><li>Children, whose lungs are still developing</li><li>Elderly individuals, especially those with existing heart or respiratory conditions</li><li>Pregnant women, as exposure can affect foetal development</li><li>Outdoor workers, who face prolonged daily exposure to polluted air</li><li>People with asthma, allergies, or other respiratory conditions</li><li>Individuals with weakened immune systems or chronic illnesses</li></ul>&nbsp;These groups are more likely to experience both immediate discomfort and long-term health complications from polluted air, making protective measures especially important.&nbsp;<h2>How to Protect Yourself from Rising Air Pollution</h2>&nbsp;Here are some major ways to do that: ·&nbsp;&nbsp;<ul><li>Use an <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air purifier</a> to continuously remove PM2.5 particles, dust, and other pollutants from indoor air.

Coughing, Breathing Difficulties, Infections: Real Consequences of Delhi's Air Pollution

&nbsp;Indoor air is often more polluted than we realise, carrying a mix of dust, allergens, pet dander, smoke, and volatile organic compounds (VOCs) that can quietly affect our health and comfort. For many households in urban areas, an air purifier for the home is no longer a luxury but a necessity for healthy living. However, buying the best air purifier is not the only work done; determining where you place it in your home decides how well it will perform. The wrong spot can restrict airflow, while the right one maximises purification, delivering cleaner, fresher air throughout the room. &nbsp;<h2>Why Positioning of Air Purifier Matters &nbsp;</h2>An air purifier works by pulling in polluted air, passing it through multiple filters, like a <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/blog/guide-on-working-principle-of-hepa-filter-in-air-purifiers.html">HEPA filter</a>, pre-filter, carbon filter, and releasing purified air back into the room. If placed incorrectly, the circulation is disrupted, causing uneven air circulation and leaving some areas unfiltered. Correct placement ensures: &nbsp;<ul><li>Maximum coverage of the room.</li><li>Faster removal of pollutants.</li><li>Efficient use of the <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air filter</a> and extended filter life.</li><li>Better value for your investment in an air purifier. &nbsp;</li></ul><h2>Placement Tips for an Air Purifier for Maximum Efficiency &nbsp;</h2><ol><li><h3>Keep It Off the Floor &nbsp;</h3>Place your purifier on a table, stand, or elevated surface about 2–3 feet high. This ensures it can draw in air from multiple directions without obstruction. &nbsp;</li><li><h3>Choose Central, Open Areas &nbsp;</h3>Position the purifier where airflow is not blocked by furniture, curtains, or walls. Corners are not the right spot as air cannot circulate freely there. &nbsp;</li><li><h3>Avoid Electronics &amp; Heat Sources &nbsp;</h3>Don’t place your purifier next to a TV, microwave, or heater. Electronics may interfere with sensors, while heat sources can affect efficiency. &nbsp;</li><li><h3>Target Pollution Hotspots &nbsp;</h3>If smoke, cooking odours, or dust are your main concerns, place the purifier near the source (like the kitchen or living area) for faster purification. &nbsp;</li><li><h3>Bedroom Positioning &nbsp;</h3>In bedrooms, place the room air purifier close to the head of the bed (but not directly beside it) to breathe purified air while you sleep. &nbsp;</li></ol><h2>Common Mistakes to Avoid &nbsp;</h2><ul><li>Blocking the air intake or outlet vents.</li><li>Placing the purifier behind sofas, curtains, or heavy furniture.</li><li>Switching it off too often—continuous operation at low speed is better for consistent air purification.</li><li>Using the wrong purifier size for your room. &nbsp;</li></ul><h2>Choosing the Right Air Purifier Size &nbsp;</h2>Every air purifier is built for a specific coverage area, so choosing the right size is crucial to get the best results without overspending.

How to Position Your Air Purifier for Maximum Efficiency

&nbsp;Clean indoor air is vital for a healthy living environment, yet most homes unknowingly trap a mix of dust, allergens, smoke, and microscopic pollutants. These invisible intruders can irritate the lungs, trigger allergies, and even leave rooms smelling stale.&nbsp; &nbsp;This is where a room air purifier becomes an essential part. However, choosing the best air purifier isn’t just about the brand or features; it starts with finding the right size for your space. &nbsp;An air purifier that’s too small for a space won’t be effective, while an oversized one for a small room may waste energy. Understanding how to calculate the right air purifier size ensures you get the clean, healthy air your home deserves. &nbsp;<h2>Why Air Purifier Size Matters For Households &nbsp;</h2>Size directly affects the device’s Clean Air Delivery Rate (CADR), which measures how quickly the purifier can filter dust, smoke, and pollen. The goal is simple: your air purification system should exchange and clean the air in your room several times per hour. For bedrooms and smaller rooms, this means choosing a compact air purifier. For large living spaces, a higher-capacity system is necessary to keep the air fresh and safe. &nbsp;<h3>Step 1: Measure Your Room &nbsp;</h3>Start by calculating the square footage of the room you want to purify. Multiply the room’s length by its width. &nbsp;For example, a room that is 15 feet by 12 feet equals 180 square feet. This number helps you identify the right purifier capacity. Many brands, including Forbes, list the maximum coverage area for each purifier model. &nbsp;<h3>Step 2: Match the Purifier’s Coverage to Your Room &nbsp;</h3>Once you have your room size, compare it with the purifier’s stated coverage area.

How to Calculate the Right Air Purifier Size for Your Home

&nbsp;Breathing clean air indoors is not as simple as it sounds. Think of a family whose home faces a busy road; every time a window opens, fine dust and vehicle fumes sneak inside. Even pet-friendly homes or spaces with smokers often struggle with odours and lingering discomfort. In all these cases, the right filter can make the difference between stale, polluted air and a fresh, healthy environment.&nbsp; &nbsp;This is where HEPA filters make a difference. By trapping microscopic particles such as dust, pollen, smoke, and pet dander, they create a safer, fresher indoor environment. Whether it’s reducing sneezing fits, easing breathing for asthma patients, or simply eliminating lingering smells, HEPA filters bring visible improvements to everyday life. &nbsp;Choosing the right air purifier often comes down to understanding the filter it uses. This guide will help you decide whether your home needs a HEPA filter or a regular filter. &nbsp;<h2>What is a HEPA Filter? &nbsp;</h2>A <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/blog/guide-on-working-principle-of-hepa-filter-in-air-purifiers.html">HEPA filter</a> (High-Efficiency Particulate Air) is designed to trap extremely fine particles from the air. A True H13 HEPA filter can capture up to 99.97% of airborne particles as small as 0.1 microns, including dust, allergens, odours, and even some bacteria. &nbsp;The fibres in HEPA filters ensure that even microscopic pollutants don’t slip through, making them a gold standard in air purification. They are particularly recommended for homes with asthma patients, allergy sufferers, or anyone concerned about clean indoor air.<a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7393300/">1</a> &nbsp;<h2>What is a Regular Filter? &nbsp;</h2>“Regular filter” typically refers to basic air filters used in appliances or entry-level air purifiers. These filters may use foam, fibreglass, mesh, or non-HEPA grade paper to trap large particles like visible dust, lint, and hair. &nbsp;While they are effective at improving general air cleanliness, regular filters cannot capture microscopic pollutants such as fine dust, bacteria, or allergens. This makes them more suitable for areas where air quality isn’t severely compromised. &nbsp;<h2>True H13 HEPA Filter vs. Regular Filter</h2>&nbsp;<figure class="table" style="width:98.38%;"><table class="ck-table-resized" style="border-color:hsl(0, 0%, 0%);border-style:solid;"><colgroup><col style="width:23.67%;"><col style="width:41.91%;"><col style="width:34.42%;"></colgroup><tbody><tr><td style="border:1px solid hsl(0, 0%, 0%);">Feature</td><td style="border:1px solid hsl(0, 0%, 0%);">True H13 HEPA Filter</td><td style="border:1px solid hsl(0, 0%, 0%);">Regular Filter</td></tr><tr><td style="border:1px solid hsl(0, 0%, 0%);">Filtration Efficiency</td><td style="border:1px solid hsl(0, 0%, 0%);">99.97% of particles ≥ 0.1 microns</td><td style="border:1px solid hsl(0, 0%, 0%);">Basic dust, lint, and larger particles</td></tr><tr><td style="border:1px solid hsl(0, 0%, 0%);">Target Pollutants</td><td style="border:1px solid hsl(0, 0%, 0%);">Dust, pollen, odours, bacteria, allergens</td><td style="border:1px solid hsl(0, 0%, 0%);">Visible dust, hair, coarse particles</td></tr><tr><td style="border:1px solid hsl(0, 0%, 0%);">Best For</td><td style="border:1px solid hsl(0, 0%, 0%);">Allergy sufferers, asthma patients, and high-pollution areas</td><td style="border:1px solid hsl(0, 0%, 0%);">General air cleaning in low-pollution areas</td></tr><tr><td style="border:1px solid hsl(0, 0%, 0%);">Lifespan</td><td style="border:1px solid hsl(0, 0%, 0%);">9–12 months (depends on usage)</td><td style="border:1px solid hsl(0, 0%, 0%);">1–6 months (varies by type)</td></tr></tbody></table></figure><h2> Buying Guide: When to Pick HEPA vs. Regular Filter? &nbsp;</h2>Choosing between a HEPA filter and a regular filter depends on your environment and health needs. If you live in a polluted city, near busy roads, or in an area with high pollen levels, a HEPA filter is the smarter choice as- &nbsp;<ul><li>Health Protection – Traps microscopic allergens, dust, pollen, and pollutants, helping asthma patients, allergy sufferers, and sensitive family members breathe easier.</li><li>Better Indoor Air – Ideal for areas with high pollution, smog, or seasonal allergens.</li><li>Long-Term Value – Though costlier, HEPA filters provide superior protection and can reduce long-term health risks.</li><li>Convenience &amp; Efficiency – Advanced HEPA purifiers are often quieter, more energy-efficient, and feature smart sensors, auto modes, or WiFi controls. &nbsp;</li></ul>When to Choose: Pick a HEPA filter when clean air and health are priorities. Regular filters are suitable when your main goal is basic air cleaning on a budget. &nbsp;Maintenance Tip: HEPA filters typically require replacement every 9–12 months, depending on usage and pollution levels. Always check for True HEPA certification to ensure maximum effectiveness. &nbsp;<h2>Forbes Air Purifiers with HEPA Filters &nbsp;</h2>To make the choice clearer, let’s look at two excellent HEPA air purifier examples- &nbsp;<ol><li><h3><a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/dp/GAPDF400Z1SM00/forbes-355-surround-360degree-smart-air-purifier">Forbes Smart 355 Surround 360° Air Purifier</a> &nbsp;</h3>Perfect for medium-sized rooms, this purifier uses True H13 HEPA filtration along with activated carbon and plasma purification for maximum efficiency.

If you want deep protection from allergens, pollutants, and fine dust, a HEPA filter air purifier is the best option. If your goal is simply basic dust control at a lower cost, a regular filter works fine. &nbsp;For households prioritising health and clean air, especially in cities where pollution is a daily concern, HEPA-based <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air purifiers</a> like the Forbes Smart 355 and Forbes Smart 500 offer reliable and advanced protection. &nbsp;<h2>Frequently Asked Questions &nbsp;</h2><ol><li><h3>Is the <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">HEPA filter price</a> worth the investment? &nbsp;</h3>Yes, they are worth the investment as HEPA filters capture microscopic particles that regular filters miss, making them essential for allergy relief and protection in polluted environments. &nbsp;</li><li><h3>Do HEPA filters remove odours too? &nbsp;</h3>With Surround 360 Air Intake Technology, HEPA filters trap particles, and for odour removal, these purifiers also include activated carbon filters. &nbsp;</li><li><h3>How often should I change my air purifier filter? &nbsp;</h3>HEPA filters usually last 9–12 months, while regular filters may need replacement every 1–6 months, depending on usage and air quality. &nbsp;</li></ol><h2>Sources: &nbsp;</h2><ol><li><a target="_blank" rel="noopener noreferrer" href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7393300/">https://pmc.ncbi.nlm.nih.gov/articles/PMC7393300/</a> &nbsp;</li></ol>

HEPA Filter vs. Regular Filter: What’s the Difference?

&nbsp;Imagine coming home after a long day, hoping to relax, only to be met with air that feels heavy, stale, or slightly off. Despite regular dusting and cleaning, the discomfort persists, your sinuses feel irritated, or your child’s asthma flares up. This is where an air purifier becomes essential. A smart appliance that silently works to keep the air in your home clean, fresh, and breathable.Indoor air can often be more polluted than outdoor air, with less visible sources like pet dander, dust mites, cooking fumes, smoke, and volatile organic compounds (VOCs). The good news? Unlike outdoor pollution, indoor air quality is something you can take control of, starting right at home. &nbsp;An <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/c/air-purifiers">air purifier for the home</a> is a practical solution to reduce these pollutants and improve the overall air quality, especially in cities where outdoor air quality is already compromised. &nbsp;So, what is an air purifier, and how does it function? &nbsp;<h2>What Is an Air Purifier? &nbsp;</h2>An air purifier is an appliance designed to remove contaminants from the air in a room, making it cleaner and safer to breathe. It draws in air, filters out harmful particles such as dust, pollen, smoke, and bacteria, and then circulates purified air back into the room. &nbsp;These devices are especially useful for people who suffer from allergies, asthma, or other respiratory conditions. However, with rising awareness about pollution and health, air purifiers are becoming a household essential even for healthy individuals seeking cleaner air. &nbsp;<h2>How Does an Air Purifier Work? &nbsp;</h2>Air purifiers generally work using a multi-stage filtration system that may include: &nbsp;<ol><li><h3>Pre-Filter &nbsp;</h3>This is the first line of defence. It captures larger particles like hair, dust, and pet fur, helping to extend the life of the other filters. &nbsp;</li><li><h3>HEPA Filter &nbsp;</h3>The <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/blog/guide-on-working-principle-of-hepa-filter-in-air-purifiers.html">HEPA filter</a> (High-Efficiency Particulate Air) is one of the most crucial components. It captures 99.97% of particles of size as small as 0.1 microns, including pollen, smoke, and fine dust, making it a must-have in any high-quality air purifier. &nbsp;</li><li><h3>Activated Carbon Filter &nbsp;</h3>This layer helps neutralise odours, gases, and VOCs (like those released from paint or cleaning agents), improving the overall smell and chemical safety of indoor air. &nbsp;</li><li><h3>Plasma Filtration &nbsp;</h3>Some advanced purifiers also include UV light or plasma ionisation to kill airborne bacteria and viruses. The device pulls in the contaminated air, passes it through the filters, and pushes out purified air, effectively reducing pollutants from your indoor environment. &nbsp;</li></ol><h2><a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/blog/benefits-of-an-air-purifier.html">Benefits of Using an Air Purifier</a> &nbsp;</h2>Using an air purifier isn’t just about combating pollution; it’s about upgrading your lifestyle and protecting your health. Here are some key benefits: &nbsp;<ol><li><h3>Improved Respiratory Health &nbsp;</h3>Air purifiers reduce allergens like pollen, dust, and pet dander, making breathing easier, especially for asthma or allergy sufferers. &nbsp;</li><li><h3>Odour Control &nbsp;</h3>Cooking smells, cigarette smoke, and musty odours can be unpleasant. Air purifiers with activated carbon filters neutralise these smells quickly. &nbsp;</li><li><h3>Better Sleep &nbsp;</h3>Cleaner air promotes better sleep by reducing snoring, congestion, and nighttime breathing difficulties caused by allergens. &nbsp;</li><li><h3>Enhanced Productivity &nbsp;</h3>Clean indoor air helps improve focus, energy levels, and mental clarity, great for home offices or study areas. &nbsp;</li><li><h3>Protection Against Airborne Germs &nbsp;</h3>Advanced models can eliminate bacteria and viruses, reducing the risk of infections, especially in homes with kids or elderly members. &nbsp;</li></ol><h2>All About Forbes Smart Air Purifiers &nbsp;</h2>If you're considering buying an air purifier for your home, Forbes offers options that combine design, filtration efficiency, and smart features. &nbsp;<h3>1. <a target="_blank" rel="noopener noreferrer" href="https://www.eurekaforbes.com/dp/GAPDF400Z1SM00/forbes-355-surround-360degree-smart-air-purifier">Forbes Smart 355 Surround 360° Air Purifier</a> &nbsp;</h3>This model is perfect for medium-sized spaces.
