15 Of the 20 most polluted cities in India as recorded by WHO. Yet shockingly, more than two million people die premature deaths due to air pollution indoors. A new study shows indoors could be five times more deadly than outdoor air! Yeah, you understood it correctly!

This is primarily due to inadequate ventilation, stove gas fumes, smoke, paint fumes, varnishes, fungal spores, and electronic devices we bring home. Since we spend most of the at-home, we have higher chances of all those dangerous allergens exposed to it.

This is where Air purifiers will be of great benefit! It consists primarily of powerful particulate filters designed to remove approximately 99.97 percent of allergens in the air.

To clean out dirty air, the best air purifier should have those sensors:

  • HEPA filters – It’s established that this particular filter mainly eliminates dust, pollen, mold, smoke, pet dander, and even hair.
  • Carbon filtering can often be used to remove gas and chemical emissions, unpleasant smell and smoke, etc.
  • Ionic sensor – This will kill dust, pollen, fungi, bacteria, viruses, and smoke.
  • UV Light – This sensor will wipe out large micro-organisms such as bacteria, viruses, germs, etc.

CADR refers here to the distribution rate for clean-air. This tests the air purifier’s cleaning speed and efficiency in eliminating airborne allergens. Another important trait is ACH. That refers to changes in the air per hour. Generally, a decent air purifier begins at a level of 6 to 8 ACH.

Other notable considerations are noise, suitable location, maintenance costs, and energy usage. If you find all of these a little daunting, don’t worry, you can go through our “Buy Guide” to make your purchasing process smooth and trouble-free.

Benefits of an air purifier

How to choose an air purifier?

Since it’s a health problem, you should be extra careful when purchasing an air purifier for your home. If you’re not aware of filter  form or other variables’ functionalities, buying one model out of so many choices may be difficult for you. Here is a thorough buying guide to help you with this to help you buy the best air purifier for your home.

Type of filter

Various air purifier filter s target various forms of air pollution. The pollutant they are targeting depends on the filtration equipment used within the device. We discussed below regarding each of the filter s.

These days most air purifiers come in with prefilters. A Prefilter is normally the first filter  layer that is mounted in front of the main filter . He is responsible for eliminating large dust particles from the air. Prefilters are like any simple filter s that eliminate dust, danders or pet fur, and larger microbes. Usually, these prefilters are made of foam or nylon and can be quickly washed. So looking for an air purifier with a prefilter is fine.

HEPA filter

HEPA or High-Efficiency Particulate Air Filters are designed to absorb 99.97 percent of airborne particles, which are around 0.3 micrometers or wide while going through the filter .

HEPA filter s can effectively eliminate airborne dust, dirt, smoke, pollen, pet dander, mold spores, and bacteria. Purchasing an air purifier with HEPA filter s may be beneficial if you suffer from asthma, allergies, or some other respiratory conditions and if you are more vulnerable to illness.

There are several filter  forms that use the acronym of HEPA, but there is only one mark that has an actual credential. You should check out the label “Real HEPA Filter.” A True HEPA Filter is accredited to remove about 99.97 percent of all 0.3 micron small microscopic particles.

Any more filter s use words such as “HEPA-type” or “HEPA-like.” These are inferior materials capable of collecting particles smaller than 2-5 microns. This leads to the purifier’s efficiency decrease of more than 600 percent.

Make sure you always look for the Real HEPA mark when looking for a HEPA air purifier.

Activated carbon

By absorbing gas fumes, smoke, pet odors, cooking odors, paints, cleaning products, and other irritants, the activated carbon filter s help to reduce the room odor. If you are sensitive to such chemicals, you may use an activated carbon filter  to check for a purifier.

This filter  uses a special type of activated carbon-containing tiny absorbent pores in millions. These pores provide a wider surface area for trapping gases, odors, and fumes.

These filter s are used in conjunction with other filter s in most air purifiers, as the activated carbon filter s cannot extract particles of dust from the air.

UV Lamp

You can purchase a model with a UV lamp if you are looking forward to purchasing an air purifier that can remove germs, bacteria, and other harmful particles from the air. A 20 Watt bulb is capable of killing bacteria, germs, and pathogens within a few seconds, according to studies performed by the California Air Resource Board. Since it does not emit any by-product of ozone, it is absolutely safe to use and can even be used in kitchens, hospitals, and laboratories.

An air purifier with a UV lamp is ideal for those places where the weather is usually hot and humid. Since they can’t handle other types of contaminants, a UV lamp filter  is used in conjunction with other filter  types to provide maximum efficiency. If they are not used with other filter s, the microbes can easily disappear and return to the ambient air with the contaminants. UV lamp filter s are either employed with HEPA filter s or activated carbon filter s in most air purifiers.

Ionic air purifiers

Often called an ionic air purifier as an ionizer, ozone generator, or ion generator. These air purifier types emit electrically charged molecules called ions into the air. The charged ions bind themselves to airborne dust, pollen, mold, and other allergens.

This charges the particles in such a way that they bind to each other, making them big and heavy to settle faster. As a consequence, the particles bind to surfaces such as walls, floors, and furniture. A few particles are floating around in the air. You should get them inhaled.

Looking at how these ionic purifiers operate, you have to realize that the air ionizer purifier is not simply collecting or removing dust particles from home. The dust particles charged by ions begin to expand and spread and finally adhere to the surface. Owing to tasks such as dusting, using a vacuum cleaner, or other household activities, these particles may be stirred up again.

Size of the room

Space size is one of the most significant variables you can look for before you purchase an air purifier. Smaller rooms need fewer air purifiers and vice versa.

Air purifiers can be found in various sizes, from small to large. So check the air purifier’s coverage area parameter and then equate it to your room size. Buying a model that offers a coverage area that’s slightly larger than the size of your room is always wise.

Clean air delivery rate

The CADR that is, Clean Air Delivery Rate, is either measured as a cubic meter of air delivered within one hour, or a cubic foot of air delivered within one minute. The CADR rating was created by the Home Appliance Manufacturers Association (AHAM) to help consumers find out how well the air purifier works and purify the air in specific size space.

The CADR rating becomes extremely relevant when you compare two air purifier models so you can buy the better one. Not all air purifier models list the CADR rating on the requirements list. Except for those manufacturers that have self-registered for the AHAM test.


ACH refers to the “Hourly Air Shift” An air purifier’s ACH rating indicates how many times an hour, the system can exchange air within a room. For example, if a purifier’s ACH rating is 5x, that means the full volume of air is exchanged five times per hour.

ACH on an air purifier is one of the least-understood ratings.

Whenever you compare two air cleaner models, it is very important to check for ACH ranking. It shows you quickly the product is better for exchanging fresh air within the room.

Replacement of filters

As well as the cleaner’s overall cost, you also have to check the filters’ repair costs or replacement costs.

Carbon and HEPA filter s need to be checked periodically. They cannot filter  air when it is completely clogged up. So if you’re purchasing the purifier with these philtres, you’ll need to review the manufacturer’s instructions to see how much these philtres need replacement. The philtres last around three months to 1 year, depending on the use.

Suppose you are going to buy an ionic air purifier. In that case, you do not have to think about the maintenance costs as they do not use a filter  that is degradable.


Every time you buy an air purifier for your home, we recommend purchasing it from a well-known, trustworthy brand.

There are so many brands out there that claim to deliver the best air purifiers, but they’re not all trustworthy. The explanation for this is that not all countries have the same product rules and regulations as those sold in the USA and Europe.

Buying a reputed brand air purifier lets you get a trustworthy product together with the best after-sales support.

How does an air purifier work?

An air purifier is made up of two major components – fan and filter . Although some cleaners come with a single filter , other philtres come in several. The fan helps to suck out the dirty air and to disperse the fresh air. The fan sucks in the air when you turn on the unit and flow through the filter . Both impurities and contaminants are eliminated from the air after they have entered the filter . Then filtered air is sent out into the local environment.

The philtres in the air purifiers are either made from fiber, wire, or paper. Regardless of the type of filter  used, it needs to be periodically cleaned. Otherwise, the purifier’s output and efficiency would be affected.


This was a quick guide to help you grab your hands on the best air purifiers available and breathe in a calm and clean environment. Bring one home and enjoy giving the best health to your loved ones.
