Best Air Purifier to buy in India - Buying Guide

Choosing the best Air purifier is important for people who want to protect the air they breathe. They help in keeping the air clean and free of pollutants. Air purifiers have been developed with various technologies, so it is important to understand what you need from an air purifier.

There are many types of air purifiers available in the market today, as per your requirement and budget, but first you should know what an air purifier is.

What is an Air Purifier? 

Air Purifier cleans the air within a specific area through a specialized filtering process that targets microscopic particles that pose harm to the consumer's health. A high quality air purifier can trap upto 99.7./0 of all air pollutants that would otherwise enter into nasal passage and lungs thereby causing respiratory illness. Air purifiers are known medically for reducing allergy symptoms, reducing asthma, improving sleep, making it easier to breathe and creating an overall better standard of living. 

What types of air pollutants can air purifiers remove? 

• Pollens 

• Plant spores and fungi

• Dust and dust mites

• Pet dander and hair Mold spores 

• Toxins from aerosol sprays and pesticides

• Volatile Organic Compounds (VOCs) found in paint, varnishes, cleaning supplies, new carpet and building materials 

• Bacteria and viruses 

• Tobacco and wood smoke, and its smell

• Household odors from cooking, pets and chemical cleaners 

Understand what to look for when buying an air purifier:

A good air purifier needs to satisfy several qualities, from size to filter type, from settings to noise.
Check out our guide on top things to keep in mind when buying an Air Purifier.

Room Size 

All air purifiers aren't equally powerful and are designed to clean air in rooms/areas of different sizes. Therefore, the first thing to note when choosing an air purifier is the place you intend to use it in. It's recommended that you choose an air purifier that's capable of cleaning the air of a larger room than the one you plan to install it in so that you can run the machine effectively on its (quieter) "low" setting resulting in less noise and less energy consumption. Also, the height of the room needs to be taken into account. 

Refer product details page for the applicable room size for each air purifier model. If you are planning to buy an air purifier for use in your bedroom, for instance, you will want to choose a model with low noise level that you can tolerate while sleeping. 

Types of filter:

Generally, all air purifiers use one of two major types of filters — 

1. Composite Filter

2. HEPA (High Efficiency Particulate Air) Composite. 

You should go for the purifier that uses the latter, since HEPA filters are much better at mechanically separating pollutants from air. A true HEPA filter removes 99.97./0 of particles that have size less than 0.02 microns. 

Composite filters, on the other hand, are efficient at inhibiting airborne microorganisms, but need frequent (every 3-6 months) replacement. Most air purifiers come with some type of indicator (e.g. LED light) that lets you know when a filter replacement is needed. 

Note: HEPA filters are generally the most widely used air purifiers and are the only type of air purifiers which meet specific EPA standards for efficiency and safety. 

3 Important things to consider when Buying an Air Purifier:

CADR (Clean Air Delivery Rate):

This is an important metric for air purifier performance and represents the level of purified air emitted by the purifier. Go for a purifier with a higher CADR since that means higher filtration capacity. Refer product detail pages for the CADR for the respective air purifier models. 

ACH (Air Changes per Hour): 

This refers to the number of times the filter cleans the air in the room it's being used in. Given the level of pollution in metropolitan cities like Delhi and Mumbai, you should choose an air purifier with a minimum ACH of 4, which means a full clean every 15 minutes. 

Indoor Air Quality Indicator:

Air Quality indicator helps in monitoring the air quality within the room. Air purifiers come with LED indicators which change colors in response to the air quality so that you can adjust the fan speed accordingly. A high end air purifier comes equipped with an auto mode function which adjusts the speed setting to automatically base the air quality. 

Some models also have a numeric PM 2.5 display which helps you measure and see the air quality. Latest models from brands like Dyson, Xiaomi have mobile apps integrated with it so that you can control air purifier operations remotely and monitor the air quality within your house.
