What is an air purifier

This device is more beneficial to allergy sufferers and asthmatics. Air purifiers can also be used in industries to remove impurities from the air before processing. Pressure swing adsorption techniques will be used for this. You should choose effective and compact air purifier for home.

To live a healthy life, the quality of the air is the most essential thing. It is our right to get pure and fresh air. The need for air purifiers is growing as pollution is increasing day by day. As the quality of air is decreasing, here is the way, which you need to buy the best air purifier in India to take healthy breathe.

Types of air purifiers for home

HEPA filter air purifiers: HEPA filters are good at filtering particles. These purifiers can trap a minimum of 99.97% of particles bigger than 0.3 microns effectively. This can trap bacteria, chemicals, viruses, and molds.

Adsorbent air purifiers: The activated charcoal adsorbent purifier can easily trap chemicals and odors which are floating in your room. These filters can sponge up toxic substances through a physical or chemical process. 

UV air purifiers:When the air is sucking into the machine, the UV purifiers then expose the air to a UV lamp. Then the UV light makes the viruses inactive and can kill harmful bacteria and fungi. UV purifiers can be used in a wide range in the medical field. Using this we can clear airborne microorganisms in the room.

Ionic and electronic air purifiers: This product works without a filter. These are of two types, ionizers, and electrostatic precipitators. The ionizers create negative ions then attach themselves to the particles floating in the air.

Then these particles settled on the surface which you can easily wipe. Whereas electrostatic precipitators follow the same, but here the particles settle on positively charged plates within the purifier. 

Types of filters used in air purifiers

Pre-Filter: This is the outermost layer of the air purifier. It can increase the lifetime of the next layers by capturing the hair, large dust particles, and mold. These are the cheapest filters.

There are two types of pre-filters the 1st one is washable which costs around Rs. 700 as it is washable you can use it multiple times. The 2nd one is non-washable pre-filters which costs around Rs. 150 to Rs. 300. These non-washable filters have to be replaced every 3 months.

Cold Catalyst Filter: It is designed to absorb and decompose formaldehyde and tiny floating dust particles in the air. It can also absorb other harmful gases like ammonia and TVOC which are present in the air. 

Activated carbon filter: This can absorb odors, chemicals, and gases from the air. It is one of the most important filters in the air purifier. When the air is passed through it at a slower rate it can absorb a high amount of VOC and toxic chemicals. 

Antibacterial filter: This filter can remove particulates and harmful irritants from the room and recirculates the pure air into the room.

HEPA filter technology: HEPA means high-efficiency particulate air. When the polluted air passes through these fine fibers, it traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.

The thickness of the filter is 0.5 to 2.0 micrometers. Depending upon the HEPA filter class it can trap up to 99.97% of particles.

Ionic Filtration: It is not the filter like other filters. It is a complex scientific process. It sends out the charged ions then these ions form a bond with potentially harmful impurities. These impurities either fall to the ground or are attracted to the collection plate unit. 

Things to consider before buying air purifier

While buying the air purifiers you need to consider the following things.

Cost of replacement filters: Generally you should replace (or clean) the filters once in every 6 to 12 months for pleated filters and 3 months for activated carbon filters. The cost of the filters varies from 20 $ to 200 $. 

Certification: To buy the best air purifier for home certification is very important. Here on the package, you have to look for a couple of labels. 1st one is the Energy Star logo.

As the air purifier runs the whole day it consumes more and the energy star certified devices 40% efficient than standard ones. The 2nd is AHAM verified seal. They provide CADR and room size on the AHAM seal.

Room size: Based on the size of the room you have to select the best air purifier in India for home. For selecting an air purifier you can trust the AHAM seal. Most of the air purifiers are suitable for larger rooms with 350 sqft and more.

Noise: As these purifiers running whole the day the best room air purifiers runs quietly. The ideal machine runs with a noise of less than 50 dB. You can find the details on the package how many dB it operates. 

Features to look

Washable Prefilters: This filter helps in increasing the life of the main filter by collecting large particles before they reach the main filter. So that you can save your money.

Filter service indicator light: This function will remind you when it’s time to change the filter. To get effective results you need to change the filter regularly.

Air quality sensor: Depending on the pollution level of the room the best air purifier in India can automatically adjust the cleaning speed.

Handles and wheels: Generally these air purifiers weigh 15 to 20 pounds, so it is hard to move the machine from one room to another room. To avoid this problem you have to choose a model with casters.

Remote Control: By using the remote control you can operate the device from any corner of the room. Some models like ‘Mi’ come with the phone app which acts as a remote.

Clean Air Delivery Rate (CADR): The clean air delivery rate will be measured in m3/hour. This indicates the volume of purified air produced in an hour. The highest rating scores for smoke and pollen are 450 and for dust 400.

Along with the above things you have to consider Air Changes Per Hour, PM 2.5 and PM 10, Effectiveness of HEPA filtration, Air exchange rate, sensor and monitor, fan speed, and, ozone levels.
