What does an Air Purifier do?

One of the crucial factors that determine the environment inside your home and one of these factors is the air quality.

We need air constantly to give us much-needed oxygen and to keep us well. But, if the air quality is impure, that can lead to disturbance in the home environment and within our bodies. 

There are many ways to keep the air within your home clean and healthy. One of the ways to ensure this is to use an air purifier. It’s a practical and easily affordable device to alleviate air quality within your home. 

In this article, you’ll read what an air purifier is, how it works, and what benefits it offers you. Let’s begin:

What is an Air Purifier? 

An air purifier is a device that helps improve the air quality of a space by removing contaminants from the room.

Air purifiers may differ based on their size, design, and mode of operation. For homes, small portable units are available for rooms, and there are also bigger units that can be used in commercial settings or to cover large homes. 

Air purifiers benefit homeowners by creating a safe environment for everyone in the house. You can use air purifiers in conjunction with other devices, such as humidifiers, or AC, to maximize the positive effects to optimize your home environment. 

Types of Air-Purifiers

Several air-purifier types are available in the market based on their design and operation. Here are some of the most popular air-purifier types that customers use. 

 a.) HEPA Air-Purifiers

Air purifiers using the HEPA (High-Efficiency Particulate Absorbing/Arresting) filters are one of the most popular air purifiers among customers.

HEPA filters can catch up to 0.3 micron-sized particles, making them highly efficient. These are one of the most advanced and effective air purification solutions for air purification. 

 b.) Ultraviolet light air purifiers

Ultraviolet light air purifiers use ultraviolet rays to kill germs or harmful microorganisms in the air. Some of these types of devices may release ozone. 

 c.) Electrostatic precipitators

Electrostatic precipitators are air purifiers that utilize high-voltage electrical energy to charge the particles that pass through the filters, killing pathogens.

These pathogens accumulate on the electrostatic plates, which need to be cleaned or changed regularly. Like UV air purifiers, these devices may also release ozone. 

 d.) Ozone Generators 

Usually used in the hospitality industry, these devices help remove odors from the atmosphere. However, these also release ozone, making the space unsuitable for inhabiting for some time. 

 e.) Activated carbon 

A commonly used air purifier effectively traps various contaminants and helps alleviate odors. However, these are less effective in capturing viruses and bacteria HEPA filter purifiers.

How does a HEPA Air Purifier work? 

All purifiers rid the air in your home of any contaminants or pathogens that contaminate the environment, affecting your health.

Various air-purifiers accomplish this in a slightly different way. One of the most popular air-purifiers is the HEPA filter air purifier, one of the most effective means of air purification. 

HEPA air purifiers consist of the outer covering of the device, a built-in fan, and HEPA filters. The built-in fan first sucks the impure air from the room, and then the air passes through the filters, getting removed from any impurities and harmful microorganisms, and gets out back into the room.

This process continues, improving the air quality of the room drastically. The rate at which the air-purifier cleans the air, and how much area it can effectively cover, differs from model to model.

Benefits of using an Air-Purifier

 a.) Eliminates harmful chemicals

If you live where there’s a lot of traffic, you’ll likely get exposed to harmful gasses like nitrogen dioxide and carbon monoxide.

These pollutants sneak into the home air supply through open windows and other openings and can adversely affect your health.

Some household cleaners also contain chemicals like ammonia, chlorine, and phthalates which can be harmful and may lead to severe health conditions like tumors, and cardiovascular and neurological disorders, among other problems. 

An air purifier with activated carbon effectively removes and cleanses these chemical contaminants, keeping you safe. 

 b.) Neutralize odors 

Unpleasant odors inside your house may come from a variety of sources. It can be kitchen smoke, pets, stored chemicals, etc., that may be the source of the unpleasantness in the home.

With an air-purifier, you can neutralize the odor inside your home and keep your home smelling fresh. Air purifiers with HEPA filters and activated carbon can trap gas and other particles keeping the space safe and odor free. However, find the source of the odor and fix it to get a permanent solution. 

 c.) Removes Pathogens 

Air purifiers help remove pathogens like bacteria and viruses from causing harm to your health. Airborne diseases such as flu and the common cold spread through the air, transmitted by tiny pathogens that flow from one person to another. An air-purifier with HEPA filters effectively traps these pathogens, making the air safe to breathe. 

In old houses, the breakdown of building material can release harmful, odorless radon gas, which can have inverse effects on your health. An air-purifier can help with its removal. 

 d.) Help reduce symptoms of breathing issues

People suffering from breathing complications such as asthma can immensely benefit from air purifiers.

Asthma patients have inflamed bronchial tubes, which can get agitated by various contaminants in the air.

It can significantly affect their health and cause their conditions to get worse. With HEPA filters, air purifiers can catch triggering factors like bacteria, fungi, pollen, dust mites, etc., and ensure that the patients can breathe safely. 

 e.) Gets rids of pet dander 

If you have pets, dander and hair can be tricky to clean. Air purifiers help get rid of pet dander and can also remove some of the hair.

However, they cannot remove all the hair, and you can use vacuuming. An air-purifier can also get rid of any smells that your pet may cause.

How to choose the right Air-Purifier for your home

You can keep a few things in mind while you’re looking for an air purifier, such as –

  • Consider your space. Whether you’re looking for an air purifier for your bedroom, living room, or larger areas, buy a unit accordingly. 
  • Consider the CADR (Clean Air Delivery Rate) of your air purifier. Typically, the ideal CADR is at least two-thirds of the room’s area, but if you live in a high-pollution area, the CADR should be at least equal to the room’s total area. 
  • Consider the filtration capacity of the air-purifier. You want a device that can catch minute particles for maximum effect. Look at different types and determine the one that fits your requirements best. 
  • Consider the noise rating.


An air purifier can be a great help if you want to improve the air quality of your space. These devices keep the air clean and are extremely useful to people suffering from respiratory conditions.

There are many different types of air purifiers, and you can choose the one that best serves your needs. One excellent option comes from Vestige, a leading MLM company based in India, the Sharp Air Purifier
