Best Air Purifier In India In 2021 [ Buying Guide & Review ]

Air pollution is one of the biggest health crises facing urban Indians today. According to a recent WHO report, 14 of the world’s most polluted cities, based on PM 2.5 levels in 2016, are in India. Kanpur held the No 1 spot with a PM 2.5 concentration of 173 micrograms per cubic meter. It was followed closely by Faridabad, Varanasi and Gaya. Here are the top 15 cities as stated in the report:

In the same report, the WHO compared 2016 PM 10 concentrations of mega cities with populations of over 14 million. It found that Delhi was the most polluted mega city while Mumbai came in fourth. Here are the top 10 cities based on PM 10 levels:

In light of these findings, it has become imperative, now more than ever, to focus on air quality and air purification. Given the high levels of pollution Indians are exposed to on a daily basis, it has become absolutely essential to ensure at least the air in our homes is clean and respirable.

Indoor air purification is an effective way to combat air pollution in cities. It removes harmful disease-causing contaminants like bacteria, viruses, PM 2.5, PM 10, total volatile organic compounds (TVOCs), pollen, dust mites, allergens, smoke and bad odors. It also eliminates sulphur dioxide, oxides of nitrogen, ozone, carbon monoxide and other harmful compounds from the air inside our homes.

While buying an air purifier is the smart thing to do, there are a few things you need to keep in mind before going in for a purchase. If you or anyone in your family is asthmatic or allergic to certain substances (Multiple Chemical Sensitivity), make sure the purifier is asthma and allergy friendly.

Buy a purifier that suits your room size. Note of the Clean Air Delivery Rate (CADR) of the device. CADR is a number which indicates the cubic feet per minute (CFM) of air or the cubic meter per hour (CMH) of air from which all the impurities of a given size have been removed. CADR is a figure of merit accorded to air filters to quantify their pollutant-removing ability.

The type(s) of filter(s) is an important detail. HEPA or High Efficiency Particulate Arrestant filter is the latest industry standard for air purifiers and a must-have. It removes up to 99.97% pollutants of size 0.3 micrometer and larger. Similarly, activated carbon, UV light and ionization are some of the technologies to look out for. The number of filters also matters. The more the number of filters, the more effective will be the purification.

Also, consider the sound level of the purifier and other features like Child Lock, real-time AQI data and filter replacement alert. Always go for an air purifier that’s easy to maintain. Also, opt for a brand that has a responsive customer service system in place. Above all, avoid gadgets that emanate harmful by-products such as Ozone.

Here is a list of the top air purifiers you can choose from.

Ooze H3O Air Series Ve2 With Aerosense And Hepa Cluster 7 Stage Purification Technology

The next high-performance air purification device is the Ooze H3O Air Series Ve2. It is equipped with a whopping 7-layer filtration system that demolishes air-borne contaminants inside an area of 1000 ft2. It has 7 different filters with seven different technologies.

The first filter is a pre filter followed by a HEPA cluster filter, an activated carbon filter, an anti-bacterial filter, a photo catalyst filter, a UV light filter and a negative ion filter. The incoming dirty air first passes through the pre filter which removes large particles like dust, lint, hair and dandruff.

The next filter is the HEPA filter which is the industry standard for air purifiers and recommended by the United States Environment Protection Agency (EPA). HEPA filters eliminate the tiniest micro bodies with a diameter of 0.3 micrometer and larger. This means it removes PM 10, PM 2.5 and even smaller particulates. It also removes bacteria, fungi, protozoa, spores and pollen.

The next level of filtration is provided by the activated carbon layer. It is a bed of carbon with enormous surface area that removes formaldehyde, VOCs and odors.

The next mechanism used by the Ooze H3O Air Series Ve2 is ionization. It is a process by which a dense cloud of negatively charged gas ions is generated by the filter to attract air pollutants which always have a positive charge. Once the gas ions fuse with the polluting particle, they cannot remain suspended in the air and fall down to the floor or stick to surfaces from where they can be removed through dusting, sweeping and vacuuming.

The purifier also uses UV light to kill harmful germs. UV-C radiation is used to incinerate spores, pollen and bacteria. The filter is also equipped with a special bacterial filter to root out bacterial presence from the air. Finally, the purifier is fitted with a photocatalytic oxidation (PCO) filter which uses UV light and titanium dioxide to break up the bonds of organic molecules and render them harmless.

Atlanta Healthcare Beta 350 43-Watt Air Purifier

Another widely popular air purifier for medium-sized rooms is the Atlanta Healthcare Beta 350. It is a 43W purifier designed for 350 ft2 indoor spaces. It has a CADR of 170m3/h and air flow rate of 225m3/h. The purifier uses a comprehensive 7-stage filtration process. It involves a pre filter, an anti-bacterial filter, a H13-grade HEPA filter, an activated carbon filter, PCO, UV light filter and an ionizer.

The first level of filtration is done by the pre filter which traps large particles like dust and pet hair. Next is an anti-bacterial filter specially designed to eliminate harmful pathogens.  Then comes the HEPA filter which removes up to 99.97% germs from the air including PM 10, PM 2.5, pollen, bacteria, spores and viruses. HEPA filters typically intercept particles of size 0.3 micrometer and larger. Hence, they are the best known filters used in air purification.

The fourth stage involves an activated carbon filter which removes gaseous particles like VOCs, bad odors, cigarette smoke and formaldehyde. The next filtration level involves a process known as photo catalytic oxidation or PCO. Under this technique UV light is shone on a thin film of titanium dioxide which releases loose electrons which then break up water vapour (H2O) into a hydrogen atom and a highly reactive hydroxyl (HO·) radicals. This HO· molecule then attacks larger carbon-based pollutants like mildew and allergens, breaking them up into smaller and harmless compounds like water and carbon dioxide.

Next is the UV light filter. It destroys microbiological particles by either burning them or disrupting their genetic code so that they cannot reproduce further. The ionizer does the final filtration. It makes air-borne pollutants stick to electrically charged gaseous ions. These ion-pollutant couplets, too heavy to remain suspended in the air, soon settle on surface like walls and floors from where they are removed through cleaning. The air purifier comes with a remote control and has a display screen, a timer and auto start function.

Key Features :

  • 7-level air purification.
  • Filters include pre filter, anti-bacterial filter, HEPA, activated carbon, PCO, UV light and ionizer.

Dyson Pure Cool Link Tower WiFi-Enabled Air Purifier

The next air cleaner we wish to bring to your attention is the Dyson Pure Cool Link Tower purifier fan. It is a dual-functionality device serving both as a fan and as an air purifier. Air is filtered using a combination of HEPA and activated carbon filters.

The purifier features a vacuum-sealed 360ᵒ H-13 glass HEPA filter pleated more than 200 times and reinforced densely with borosilicate microfibers. The HEPA filter removes 99.97% air-polluting substances with diameters of 0.3 micrometer and larger. This includes PM 2.5, PM 10, bacteria, pollen, spores, dust mites and pet dander.

The tris-coated activated carbon filter eliminates TVOCs, formaldehyde, benzene, ammonia and bad odors. The Dyson Pure Cool Link Tower air cleaner is Certified Asthma and Allergy Friendly by the Asthma and Allergy Foundation of America.

The device uses advanced Air Multiplier technology with oscillation function to project fresh air to the farthest reaches of the room. One important thing to note is that while most air purifiers rely on high face velocity to force air through their filters, the Dyson Pure Cool Link Tower applies low face velocity to do the same. The reason behind this is that high face velocity may result in the inadvertent release of pollutants trapped by the filter back into the air, but low face velocity ensures that they remain trapped in the filter and never escape.

A cool feature of the Dyson air cleaner is that it has inbuilt Wi-Fi and can be managed via Alexa voice control through Echo Dot and other Amazon smart home devices. It can also be controlled remotely through your smart phone using the Dyson Link app.

The app lets you manage all the functions of the purifiers and also shows live AQI data and provides filter change alerts. The purifier has 10 preset modes, Auto mode, Sleep mode and a Timer. It does not have any exposed spinning blades and filter meshes, and is therefore safe to handle and easy to clean. The device is accompanied by a remote control.
