The rapid rise of the residential air purifier market, convincing reports on the needs of indoor air filtration, and the recent pandemic threat has all been urging factors for us to splurge on air scrubbers.

But does indoor air really need a filtration unit, do air purifiers live up the hype to keep us safe from air allergies and asthmatic diseases, or are they worth buying, are real matters of concern if you are planning to buy one.

The reasons our air needs purification

Air pollution, one of the biggest environmental phenomena we are facing these days. From the smoke on roads to the pesky dirt particles settled on the surface of your every household, you can clearly experience it everywhere.

So, how come we breathe in the same very air and avoid the harms it does to our health. Moreover, large dust particles are the only contaminated we can see with the naked eye. But in reality, the air we breathe contains more unseen toxic chemicals including but not limited to ozone, carbon, and formaldehyde.

Indoor air detoxification:

Our indoor air quality could be even more polluted, as the cleaning products we use to destroy germs and odors give off health-hazardous volatile organic compounds.

Besides the air in our homes can host more pollutants as it includes gasses from the kitchen, ozone from home appliances, secondhand cigarettes smoke, and humidity from our laundry rooms, etc.

All these gasses and VOCs when circulating in our indoor air 24/7 can prove to be a real health threat.
In these demanding situations of a dust-free home and chemicals free oxygen intakes, we can use plenty of safe ways to make indoor air more fresh, healthy, and safe to breathe in.
Air purifying plants and a good ventilation system could be used to reduce airborne chemicals. And for the tiniest bits of toxic air contaminants, you can opt for air purifiers.


An air filter is an electrical device that aims to vacuum toxic contaminants from air including dust, pollen, molds, animal fur, and more. Air purifiers designed to make your space’s air crisper, better-smelling, and fresh to breathe.

The air purifiers that come with True Hepa filters, and carbon filters, can effectively remove smoke, viruses, VOCs, and germs from the air to prevent you from allergies, asthma, and lung diseases.

How do air purifiers work:

If we’d have to give a one-word answer it would’ve yes, but let’s dug into some further details to know the whys and wherefores?
Although air cleaner or purifiers doesn’t vacuum 100% of air pollutants still they are widely known to target the largest amount of air allergens with their smart filter technology.

Air purification units are reportedly beneficial for asthmatics and allergy suffers.
They suck the air through their fans and pass it through various types of filtration to vacuum the dirt and pollutants, and then the filtered air circulates back to your rooms.


This most effective High-efficiency Particulate Arresting filtration technology removes 99.97% of microscopic air particles down to 0.3 microns in size. These are supposed to be the tiniest air particles that couldn’t be seen with the naked eye.

The particles removed by HEPA filter include dust, pollen, dust mites, hair pet, pet dander, viruses, smoke, and more.


These filters shoot negative ions into the air and create a static charge around airborne particles making them heavier and dropping on surfaces, so you can’t inhale them.


Also known as HEGA (high-efficiency gas absorption) filter.
Made up of small charcoal pieces this filter’ uses carbon cloth that absorbs a large number of contaminants. It removes VOCs and other toxic gasses and odors from the air. It takes out bacterial and fungal infections too.


With the increasing notion of indoor air purification, many well-reputed brands have come up with different kinds of air purifiers.

These gadgets come in various sizes, capacity, and for specified targeted air concerns.

Here are the top five air purifiers in the market to help you find the righteous one according to your budget, room, and need.
