Comprehensive Air Purifier Buying Guide: From Considerations to Smart Purchase Tips

Wondering how to select an air purifier for home? Well, with an abundance of options and features available in the market, navigating the world of air purifiers can be overwhelming. However, making an informed decision when selecting an air purifier for your home or workspace is crucial.

To simplify your process, we have an air purifier buying guide that will help you choose among the best air purifiers for your home. It will help you understand the critical factors to consider when picking an air purifier while understanding your specific needs to evaluate the specifications.

Do you need an Air Purifier?

Whether or not you need an air purifier depends on several factors, including your specific circumstances and concerns. Here are some considerations that will help you decide if an air purifier is necessary for your situation:

1. Poor Air Quality:

If you live in an area with high levels of outdoor air pollution or have indoor air quality issues due to factors like smoking, cooking, or a lack of ventilation, an air purifier can help reduce indoor pollutant levels.

2. Allergies or Respiratory Issues:

If you or someone in your household has allergies, asthma, or other respiratory conditions, an air purifier can help reduce allergens and irritants, such as dust mites, pet dander, pollen, and mould spores from the air.

3. Health Conditions:

Consider any underlying health conditions that might affect your air quality needs. People with respiratory issues like asthma or Chronic Obstructive Pulmonary Disease (COPD) may benefit from air purifiers with specialised filters and higher airflow rates to improve breathing comfort.1

How Do Air Purifiers Function?

Air purifiers work by cleaning and purifying indoor air through a series of filtration and purification processes. Here's how they function:

1. Air Filtration:

Air purifiers use fans to draw indoor air through one or more filters. These filters are designed to capture various contaminants and pollutants present in the air, including dust, allergens, smoke particles, and more.

2. Pre-Filtration:

In some air purifiers, the polluted air first passes through a pre-filter. This pre-filter is responsible for filtering out larger particles, such as dirt clusters and dust.

3. HEPA Filtration:

Many air purifiers employ High-Efficiency Particulate Air (HEPA) filters, which are highly effective at capturing tiny particles, including bacteria and allergens. HEPA filters can trap particles as small as 0.3 microns in size.2

4. Optional Additional Filters:

Some air purifiers include additional filters, such as activated carbon filters and Plasma Filtration which are effective at removing odours, gases, and Volatile Organic Compounds (VOCs) from the air.

5. Circulation:

As air moves through the filters, the cleaner, purified air is then recirculated back into the room, resulting in improved indoor air quality.

Things to Consider When Purchasing an Air Purifier in India

Buying an air purifier in India can be a smart investment, especially in cities with high levels of air pollution. However, there are several factors to consider when choosing the right air purifier.

1. Room Size:

Determine the size of the room where you plan to use the air purifier. Measure the square footage of your room by measuring its length and width in feet and multiplying the two numbers. Different purifiers are designed for various room sizes, so choose one that matches your requirements.

2. Filtration System:

When selecting an air purifier, it's crucial to check the type of filtration system it uses, as this determines its effectiveness in removing airborne particles and pollutants.

Here are some common filtration systems found in air purifiers:

  • HEPA (High-Efficiency Particulate Air) Filters: HEPA filters are highly effective at capturing particles as small as 0.3 microns, including dust, pollen, pet dander, and some bacteria. They are a standard choice for air purifiers due to their excellent filtration capabilities.2
  • Activated Carbon Filters: These filters are effective at adsorbing odours, gases, and Volatile Organic Compounds (VOCs). They are often used in combination with HEPA filters to provide comprehensive air purification.
  • UV-C: UV-C lamps emit ultraviolet light that can destroy or inactivate bacteria, viruses, and mould spores. They are often used to complement other filtration methods for added germ-killing power.
  • Ionizer: Ionizer releases negatively charged ions into the air, which attach to positively charged particles, such as dust and allergens, causing them to become heavier and fall out of the air.3

3. Additional Features:

Look for purifiers with features like smart connectivity, air quality monitoring, and programmable timers for enhanced convenience.

Look for features like:

  • Air Quality Monitoring: Air quality monitoring is a crucial feature that allows the air purifier to assess the quality of the air in your space in real time. Sensors within the purifier detect various pollutants, such as particulate matter (PM 2.5), Volatile Organic Compounds (VOCs), and more.
  • Remote control: It allows you to operate the air purifier from a distance without physically interacting with the unit. With a dedicated remote control, you can quickly adjust settings such as fan speed, mode (e.g., sleep mode, turbo mode), and timer hassle-free.

4. Noise Level:

Consider the noise rating of the purifier, especially if you plan to use it in bedrooms or quiet spaces. Quieter models are preferable for peaceful environments.

5. Warranty:

Check the warranty period offered by the manufacturer. A longer warranty can provide peace of mind regarding product reliability.

6. Maintenance:

Some purifiers require regular cleaning or filter replacement. Check the requirements to ensure you can maintain the purifier easily.

7. Accessories:

You also have the option to select from a variety of air purifier accessories, including carbon filters and enhanced lung filters, to further improve the filtration quality.
