If you’re reading this article then you might have an idea about air purifiers but before we begin I’d like to provide some in-depth information on this topic to help you make the right decision while choosing the best air purifier for your home in India.

What is an Air Purifier?

The best air purifier in India is an indoor device consisting of one or two fans and filters. This device is used to filter household or industrial air. Air purifiers are mainly used to purify the air by eliminating air pollution in the home, improving air quality. This device limits the spread of harmful residues or allergens with the help of under-mounted filters and protects against respiratory problems or allergic problems in at-risk people (such as children, the elderly, and sensitive people, etc.). These devices are also used by people who have no particular problems but want to protect their health and family. In modern times, an air purifier has become one of the most essential appliances in the home

Functions/Uses of an Air Purifier

The purpose of air purifiers is to eliminate all harmful and allergic substances in the air with the help of filters and provide us with pure air.
Normally the air contains many elements such as toxins, germs, bacteria, odors, etc., which are separated with the help of different filters. These elements are so small that a person cannot see with his naked eyes. But they are very harmful to human beings. Due to these, a person gets many diseases like difficulty in breathing, allergies, etc.

We will explain how air purifiers work

  • Pre-filter:- This is the first filter that comes in contact with normal air. It removes dust and mold particles easily. It is made of filter foam, fiberglass, cotton, or another particle-mesh material. This causes less pressure on other filters and they work well.
  • Allergy Filter: This filter eliminates the allergens present in the air.
  • Deodorization Filter:- This filter is made of activated carbon and eliminates the smell of the air.
  • HEPA Filter:- The HEPA (High-Efficiency Particulate Arrestance) filter eliminates the bacteria and viruses present in the air. This filter also prevents harmful elements such as PM2.5 present in the air. In this phase of air purification, most of the pollutants are removed.

Types of Best Air Purifiers in India

There are five types of air purifiers available in the Indian market. Different air purifier companies use different air purification techniques to purify the air. Some of the filters that air filters use are charcoal absorber or mechanical, electrostatic, ionizer, ozone, and ultraviolet, HEPA, etc.

Adsorbent Purifiers

Absorbent purifiers are low-cost filters made from activated carbon or zeolite pellets. Such purifiers are very effective in preventing odors and chemical gases present in the house.
If using HEPA filters along with activated carbon filters, these purifiers are effective in preventing dust, molds, bacteria, pet hair, etc.

UV Light Purifiers

UV air purifiers use short-wave ultraviolet light rays (UV-C light) to inactivate airborne pathogens and microorganisms such as mold, bacteria, and viruses. Like all air purifiers, the job of these purifiers is to clean the indoor air. But if it has UV light, it is also called UV germicidal radiation or UVGI air purifier. But you do not use it directly against air pollutants.

A UV light lamp is fitted inside a purifying device, the indoor air passes through a beam of UV light, which helps kill germs, bacteria, and other molds in the air.

Because UV-C light is used in it, ozone is produced in small amounts during this process.

Let me tell you, the UV-C light air purifier works perfectly with the HEPA air purifier system only. Research has shown that a UV-C air purifier does not look as effective as a stand-alone unit because it cannot trap or remove particles in the air (such as dust, etc.).

Ionizers, Electrostatic Air Purifiers

These are the least widely used methods of air purification. Ionizers, ozone, and electrostatic filters are all three different methods but operate on the same principle.

Particles present in the air have negative charges, which are given a positive charge through ionization. These negative charge particles together with the positive charge particles change into particles and settle down.

Ionized particles are collected on the ground through this process, which can be manually cleaned while other air purifiers do not have this facility.

HEPA purifiers

What exactly is a HEPA filter? How it is working? and why is it so important? Also, what is HEPA air cleaner?

If you are asking those types of questions, then this post is for you.

So, keep reading.

The HEPA (High-Efficiency Particulate Air) filter is a special type of filter that captures 0.3-micron microscopic particles. The filters are generally made of fiberglass material.

As the name suggests, HEPA air cleaners are devices that clean air by removing microscopic contaminants (such as dust mites, pollinators, mold spores, pet dander, bacteria, smoke, etc.).

This gives you clean, fresh air to breathe inside your home.

The HEPA air cleaner is great not only for people with allergies or asthma but also for those who enjoy a healthy life and a clean home.

You cannot remove viruses, odors, or chemical gases through HEPA filters. Because all these particles are smaller than 0.3 microns while HEPA filter is made for a size larger than 0.3 microns. Another type of filter is required to trap them.

Types of HEPA filters:

  • True HEPA,
  • HEPA-like,
  • HEPA-type
  • Simple HEPA

Essentially, a true HEPA filter is the best type because it is certified to capture 99.97% of particles below 0.3 microns in size.

It includes a wide range of indoor contaminants.

On the other hand, filters labeled as HEPA-like, HEPA-type, or simple HEPA can only hold particles 2 microns or larger.

True HEPA and other HEPA filters have a difference of more than 500% in efficiency and these filters cannot capture ultra-fine pollutants.

So, the best advice you can follow here is to buy only an air cleaner that uses a True HEPA filter.

Other types are not just worth the money. If the cleanest air is possible then your biggest concern.
