10 Best Air Purifier in India for 2018 (Types & Buying Guide)

best air purifier indiaWant to buy the best air purifier for home use? But do you know which ones are the top rated air purifiers in India? An air purifier is such a device that removes all the pollutants and the contaminants from the air. It is not just a cleaner environment that you get with a room air purifier. Also, the environment created inside the house is much safer for your health.

But how the air purifier works? It is actually a type of filter that works in sucking the air and then cleaning it with a mechanism. Now, this procedure releases fresh air which gets the environment much purified. However, the technology used in the purification differs in different purifiers.

Why You Need Air Purifiers At Home?

The population of India is increasing day by day so there is a vast increase in the number of vehicles. Nowadays most families have their own private car and some have more than one or even few families have various cars. So due to this reason, the number of vehicles has increased to a large extent.

The increase in the number of vehicles means that a large amount of pollution is also generated and this has become a major concern in urban cities like Mumbai, Chennai, Delhi, and Kolkata. As India is developing very fast a lot of factories are being set up which again generates a huge amount of pollution and affects the human beings causing respiratory disorders.

It is also very harmful to those who are already suffering from respiratory problems. So in order to avoid these problems, it is advisable to have an air filter at home, especially an air purifier for allergies. An air purifier or air cleaner is basically a device which removes contaminants from the air in a room.

Types of Air Purifiers in India

There are two types of air purifying technologies, Active and Passive. Active air purifier uses ionization for cleaning the air. Passive air purification units, on the other hand, use air filters to remove pollutants.

As mentioned in the above paragraph the level of pollution is increasing day by day and as a result majority of the people are suffering from respiratory disorders, asthma etc, most of the time this is becoming a chronic disease. So in order to combat this situation and stay away from these kinds of diseases people nowadays prefer to use air purifiers/filters which reduces the pollution level to a large extent by simply purifying the air around them.

Generally, there are 5 types of Air Purifiers which are listed below.

  1. Filters
  2. Ionizing Purifiers
  3. Ozone Generators
  4. Adsorbents
  5. UV Light


Some air purifiers clean the air by passing it through a filter that removes harmful particles. These are sometimes called air cleaners. In households, these filters are usually part of the heating or cooling system. Air filters can be expensive, and they have to be replaced in order to keep them functioning properly

Ionizing Purifiers

These air purifiers use a method called corona discharge to create charged molecules called ions. Most atoms in the air have a neutral charge as they have the same number of negatively-charged electrons as positively-charged protons.

Ozone Generators

An ozone generator works much like an ionizing purifier, but it is designed to alter molecules of oxygen and turn them into ozone, a molecule made up of three oxygen atoms. Manufacturers of Ozone Generators claim that the ozone deodorizes disinfects the air.


These purifiers incorporate an adsorbent material to take care of odors, fumes, and chemicals in the air. Adsorption is the process of one substance being trapped on the surface of another substance. The most common adsorbent is activated charcoal, which is extremely porous and has many microscopic “nooks and crannies” to trap passing molecules.

UV Light

Ultraviolet radiation renders certain micro-organisms which are sterile thus harmless. These air purifiers feature a UV light that bathes the air as it passes through, eliminating the potential harmful airborne bacteria and viruses.

Air Purifier Buying Guide

Requirements of the air filters/purifiers are increasing day by day to encounter the high pollution level but before purchasing an air purifier/filter customers must follow few guidelines so that they can get the best purifier/filter and ensure total safety against high-level pollution.

There are many factors which must be followed before buying an air purifier. It is very important to go through the specifications of each model and not blindly believe the sales executive. Thus before buying an air purifier/filter, we must note the following.

  • Basic factors
  • Performance
  • Certifications
  • Types Of filters
  • ACH value

Basic Factors

Basic factors mainly include

  • Size of the room in which the air purifier is installed
  • The cost of replacing air filter and electricity costs should be kept in mind


The performance of the air purifier is a major factor which must be estimated before purchasing the air purifier. The performance of a particular air purifier model is rated by its coverage area, Clean Air Delivery Rate (CADR) and Air Changes per Hour (ACH). So air purifiers must be purchased only after determining the above three factors as it controls the performance of the air purifiers.


There are basically two standards American and China certification that are taken seriously in the industry. Most air purifiers that are available in India do not have any of these certifications. Both the certifications ensure a minimum quality and performance standard for an air purifier model.

Types Of filters

This is another factor which is very important to determine before purchasing an air purifier. The quality and type of filter determines the effectiveness of an air purifier. Specific filters target different components of air.

The most commonly available filter type is HEPA (High Efficiency Particulate Air). It can filter most (up to 99.9%) air borne particles of small sizes of up to 0.3 microns. HEPA filters are more than enough for a general use.

Some brands provide ultrafine particle filter along with the HEPA filter to target particles even finer than 0.3 microns.

HEPA filter is combined with the activated carbon filter to remove odor. In some brands, filters can be customized as per the requirement of the user.

Filters with antibacterial coating kills air borne germs and bacteria. Few air purifier models offer a washable pre-filter to capture dust and other large particles. People must opt for a model with pre-filter as it increases the life span of the filter inside.

ACH value

Air Changes per Hour (ACH) is basically how often an air purifier can clean the air of its claimed coverage area in an hour. This is important because pollutants constantly enter the room and the air purifier needs to constantly clean the air.

For example: Delhi is a very polluted city so people must opt for a air purifier of 4 ACH. This means that the air purifier is capable of cleaning the air of the entire claimed area four times in an hour or every 15 minutes the air inside is completely replaced.

So these are basically the main five factors that must be kept in mind before purchasing an air purifier online. But apart from these, there are a few other factors as well which include the total lifespan of the air filter and the noise level of the air filter.
