Best Air Purifier in India – Buying Guide

Air Purifiers also prove to be beneficial in eliminating odor in the room and keeping the room fresh and odor-free at all times. This can be from all the cooking done in your kitchen or cigarette smoke or even for people who are very prone to allergies. You would have often noticed dust hiding in furniture or linen that could degrade the air quality of your home Because of all these reasons, people have started investing in an efficient air purifier that meets their need and helps them to have a healthy life ahead.

Air Purifiers are commonly classified based on the type of filtration system that is used to purify the air. Based on the types of filters, following are the types of air purifiers :

1. HEPA Air Purifiers

HEPA stands for High Efficiency Particulate Air Purifiers. HEPA Filters are the most commonly used filters in air purifiers. This is because it has the ability to sense and remove harmful particles that are larger than 0.3 microns. We can only see objects that are larger than 10 microns so 0.3 micron particles are something we can’t even see and HEPA can eliminate them for us. It does all this process without using any harmful chemicals, thus further promotes safe environment for us.

2. Ionizers

Ionizers use involvement of chemicals for purifying the air in the surrounding. So basically, ionizers release negative ions into the environment that attract harmful particles to itself. Once attached to the ion, the harmful allergens weigh down to the ground or get stuck in the wall. Ionizers are not always preferred because it does not remove the harmful particles from the air but only displaces them to the ground or wall. So you still remain prone to the damage of those particles.

3. Activated Carbon

Activated Carbon has received popularity recently when it was used to treat drinking water and clean it. Later, it was discovered that it is able to sense variety of different types of allergens ranging from harmful gases to smoke, odor etc. Activated Carbon absorbs these pollutants and they can never come out of it. That is why, these activated carbon filters needs to change occasionally when it reaches a saturation point. It is recommended for children and people with breathing problems and prone to allergies.

4. Electrostatic Filters

These are the most efficient and function similarly as HEPA Filter does. The difference is that it uses electric charge to entrap the allergens instead of using the normal air filters. The charged particles then stick to the surface of the purifier, thus cleans the air off the pollutants. They have a diverse range of allergens that it can trap, ranging from dense smog, pet odor, pollen etc.

5. Ultraviolet Rays Filters

These filters are not used as the only filter in an air purifier. This is mostly because it can only destroy microorganisms and has no control over the particulate matter. Another way they can work is by converting molecules of oxygen and water into ozone and hydroxyl which then reacts with the pollutants and destroys them. But there are a lot of harmful effects of ozone in the environment, thus UV Filters are not used alone. They are often used as a secondary layer along with HEPA or activated carbon filters.

So how does an Air Purifier actually work?

Air purifiers work on a simple principle of inhaling the existing air in the environment and then cleaning it and exhaling purified air back into the surrounding.

The process of purification varies depending on the type of filtration system used.

Generally, the filtration system is made up of a collection of different layers, each of which has some specific task to perform.

HEPA Filter Purifiers perform 3 basic functions – Diffusion, Interception and Impaction. Diffusion works for small particles that get trapped in filters. Interception makes medium sized particles to stick to the surface of the fibers and finally impaction where collision of large particles result in their capture by the fibers.

HEPA Filters are not capable of eliminating odors and gases. Thus, another layer of filer is generally added which is activated carbon. Activated Carbon, when porous, has the ability to absorb huge amounts of pollutant matter. It can be used to absorb harmful gases and toxins from the air.
