Air Purifier Buying Guide

In the present day, we are all tangled up in outdoor air pollution. But we’ve got news for you. It may come as a surprise that indoor air is no longer pure, dust-free or fresh. This, together with outdoor air pollution looms as a threat to our lives which claim immediate attention.

On top of that, the excessive use of deodorizers, tobacco smoke, dust, and varnishes emit impurities into the air which, when inhaled can cause not only severe respiratory diseases and even cancer.

Air is among the four major elements including Earth, Fire, & Water. What a pity to shed its purity – that’s the horror of it.”

It is held to be certain that insect repellents are among the most harmful contaminants present within the air causing domestic air pollution.

It bears repeating, to note that air conditioners and refrigerators contribute not only in Global Warming but also produces unhealthy gases which are toxic for our health and hygiene. In the present scenario, it seems like the pollution will stop at nothing.

It is a wonder that when we light up incense sticks or camphor we fail to notice the discharge of hydrocarbons in the air. Besides, animal dander and pollen can give rise to skin allergies, infections, and respiratory tract.

Detergent powders, toilet cleaners, liquid phenyl, chlorine-by products are equally adverse and happen to be amongst the most hazardous sources of domestic/indoor air pollution.

This ongoing list seems to know no bounds which are pretty alarming, but fear not! Today, we lay out a catalog of 12 Best Air Purifiers in India, which are well-grounded and after careful consideration is worthy of merit.

“Where’s my sunflower? Asked the sun. It died for the want of fresh air I answered”.

Principal Cause of Indoor Air Pollution

First and foremost, indoor air has a high requirement for cross ventilation to its full extent. Lack of proper airing can give rise to the number of pollutants within the walls.

For reasons listed above, the impurities multiply and we fall victim to domestic air pollution. As a consequence of these impurities, why don’t you rev up for using air purifiers or air filters?

Air Purifier to the Rescue

Overall, it may be said the need for air purifiers felt to address the needs of an impurity-free environment.

To sum up, air filters first came to the aid of combating against the invisible pollutants which are present in dust, perfumes and deodorants, radon gas, draperies and upholstery, synthetic fragrances, second-hand tobacco, chemicals used in certain paints and so on.

Allow us to untangle every possible impurity you may come across indoors –

  • Airborne particles – dust in particular
  • Second-hand tobacco smoke
  • Household gases – chimneys, carpets, and upholstery
  • Volatile organic compounds

A prime example is the size of pollen which varies from that of animal dander, spores, fungi, dust mites. The scale of such particles can range from 0.04 microns to 100 microns straight, where one micron is equal to 1/25000 of an inch.

On the flip side, these microns hover with a thickness of a human hair that floats in the air we inhale which can cause breathing difficulties, likewise chronic respiratory diseases.

To the best of our knowledge – the HEPA filter is the finest appliance in the market to suffice such airborne pollutants.

It is vital to note that the appliance with a true HEPA filter cap can trap 99.97% of microscopic allergens as small as 0.1 microns.

In addition to this feature, it promises effective filtration and uniform distribution of purified air throughout the room makes it a paragon for bedrooms as well as living rooms.


So far as is known – impurities differ in sizes. Allow us to introduce you with PM2.5 which bears the hallmarks/resemblance to a grain of salt.

We can safely assume that this Lilliputian will melt away before our naked human vision on the spot. But, they are assembled in the atmosphere, that too, in a large amount.

In the final analysis, it was found that inhaling this is excess can result in the prognosis of various lung diseases and can damage other organs in our body. To make matters worse, this can choke our respiratory system.


Let us direct your attention to PM2.5’s carbon copy – PM10. These particles are slightly larger in genesis with a diameter of not more than 10 micrometers.

By way of comparison, PM10 are comparatively larger in size exacting a serious toll which can hamper our lifestyle by inviting serious diseases.

CADR: Clean Air Delivery Rate

To make a long story short, CADR is an instrument that calculates the speed featured by an air purifier. The ultimate figure indicates the amount of air (in cubic feet) the air purifier can purify within a minute.

This figure can also be converted in cubic meter per hour and likewise, the higher the CADR more preferable for efficiency. We are left with the impression that CADR numbers differ for dust, pollen, and smoke with regard to air purifiers.

HEPA: High-efficiency Particulate Arrestance

The leading function of the HEPA filter is to shut in the dust and dirt. The mechanism depends to some degree on the size of the particles which may be differing. Categorically they are inertial impaction, diffusion, interception and decidedly sieving.

By this, we imply that the air purifier come equipped with HEPA filter a to portray with imperium. There are a great many types of air filters which have close affinities to one another.


It remains the recommendation that the thicker the first line of resistance, the better. They bring pressure to bear on the impurities and trap the larger particles of dust, animal hair and other contaminants.
To crown it all, Pre-Filters are the first coating which restrains the impurities.

Activated Carbon-Filters

The foremost task of the activated carbon-filters involve elimination of VOCs and the poisonous odour, which is produced by distinct materials and gases fall largely to these Activated Carbon Filters. They ‘adsorb’ the unpleasant odours and noxious gases and neutralizes them. Here, if you’ll notice ‘adsorb’ refers to the adhesion of atoms from the gas to its surface.In essence, one pound of activated carbon has an initial surface area of not more than 150 acres. From our viewpoint, the larger the carbon filter, the better will it be suited for the air purifier. But to make the component long lasting, we need to replace it often.

Ion and Ozone Generators

To understand these generators, Let us direct your attention to a football field. For instance, when a Goalkeeper prevents the opposing team from getting the ball into the goal he clings onto the ball and brings it down.

Closely in the style of a goalkeeper, these ozone generators create ions (or, charged particles) which cling to the impurities and pulls them to the ground owing to their weight.

The minor setback is that inhaling ozone is noxious for our health. Ozone depletion is subjected to affect the environment.

These filters purify the impure air and alter it. It has to be said that these are the various types of trending filters available in the market.

Before purchasing the best purifier, you need to keep in mind the following factors that are as follows:

Coverage Area – You need to make sure that the coverage area of the air purifier covers up your entire room.

ACH ratings (Air Change per Hour) – This is crucial with a degree of how often the air purifier can exchange the air in the room provided. For instance, if our room is of length 20′ x 20′ and an air-filter with ACH ratings of 6, it will convey that the air filter can exchange the entire air in the room 6 times/hour.

Price – It differs from model to model. Most of the air purifiers are inexpensive picks but you should keep in mind the cost of filter replacement annually or quarterly.

Energy Usage – To understand this factor in brief, go through the Star ratings for this prospect given by Bureau of Energy Efficiency.

Noise Level – Apart from the above-listed factors you also need to consider the sound of the air purifier. Higher the fan speed, you’ll witness louder, brighter tone.

CADR – This has been discussed above.

Indoor Air Pollution
