Top Rated Best Air Purifiers to Buy in India in 2021

Human has reached as far as Moon and Mars; but to the detriment of Earth’s atmosphere. Mankind has ruined the air to breathe on the appellation of advancement in technology. Air has been contaminated due to smoke particles, Volatile Organic Compounds (VOCs), combustion products, pesticides, dust particles, radon, viruses and bacterias. Such indoor air pollution devastates the wellness of human beings especially allergy sufferers, asthmatics, infants, toddlers, aged and sensitive people. Air purifier acts like a boon for such people and allow them to breath of fresh air.

Air Purifying Technology

There are two types of air purifying processes- Active and Passive. Active type air purifiers release negatively charged ions into the space by causing pollutants to stick to the surface, thereby providing clean and ambient atmosphere. On the contrary, Passive type air purifiers have High-Efficiency Particulate Air (HEPA) filters. It removes the dust and particulates permanently from the air by passing the indoor air through the filter trapping all contaminants, thereby providing untainted and fresh air.

Uses, Benefits and Drawbacks of Air Purifier

Air purifier serves us innumerable health benefits by eliminating dust, pollen, mold spares, dander, dust mite feces, smoke particles (including second-hand tobacco smoke) and VOCs. Air purifiers with HEPA filter also help in reducing the transmission of coronavirus and several other air-borne viruses. Despite of various advantages of air purifiers, there are several harmful side-effects as well of appliance.

  • Emission of Ozone gas – Some air purifiers, like ozone generators and ionizers, emit ozone to remove harmful chemical bacterias present in the air. Air purifiers with electrostatic precipitators emit ozone inadvertently. Ozone is a toxic colorless gas which is naturally present at the stratosphere and is also a component of smog. Being toxic, it can cause shortness of breath, chest tightness and enhancement in asthmatic conditions.
  • Under performance – Most of the air purifiers don’t serve the claimed capabilities. Air purifiers with HEPA filtration are effective against allergens and micro organisms but fail to eliminate odors, gases and other harmful chemicals; vice-versa is in the case of purifiers with activated carbon.
  • Expensive – Apart from the purchase price of air purifiers, maintenance of this appliance is also hard on the pocket. Filters demand replacement from time to time.

FREQUENTLY ASKED QUESTIONS (FAQs)

Do air purifiers really work or a waste of money?

In case you are willing to know that whether air purifiers are really effective or just a waste of money, the honest response is here. Doctors recommend air purifiers to people with allergies and respiratory problems if the major reason of their illness is the air where they breath. Spending on a HEPA filter air purifier (not HEPA- type purifier) is a wise decision. On the other hand, ionizers and ozone generators are not less than wastage of money as they may cause risks to the eyes, uneasiness in breathing and allergy-like condition.

Why are air purifiers bad for your health?

As explained above, many air purifiers emit toxic ozone gas as a byproduct of filtration which can cause respiratory and asthmatic problems like shortness of breath, chest pain, cough and throat irritation.

Should I sleep with air purifier on ?

You need clean and fresh air to breath round the clock; especially with the omnipresent threat of air pollution. Air purifiers with HEPA filter can safely be run unattended and for long hours during day and night.

Where should I place my air purifier?

Many people get confused while choosing the best location for an air purifier. It is advisable to keep the front face of the appliance in such a way that it can espy every spot and stretch of the room. You should avoid keeping the appliance under a shelf or behind an object (like sofa, table or cupboard).

Do air purifiers protect against corona virus?

Are air cleaners effective against Coivd-19? HEPA filters and UV light air purifiers have the expected potential to reduce or disable SARS-COV-2 (like many other viruses) significantly (approx. between 99.5% to 99.9%), provided that the purifying appliance is run over a period of time and the villain virus gets a long exposure to UV light. But it doesn’t mean that you stop taking preventive measures of wearing a mask, sanitizing your hands and maintaining social distance. If a person is diagnosed as Covid positive, it is mandatory to quarantine him. Air purifier will only act as an additional line of defense to reduce the spread of virus to caregivers. Also note that the size of corona virus is somewhere between 0.06 micron to 0.14 micron; whereas most of the HEPA filters are tested against 0.3 micron size viruses only. Thus air purifiers should be used as an additional defensive device besides masks, sanitizers, and social distancing.

Do you need air purifier for every room?

Most of the air purifiers are easy to move from one place to another within the house. You should consider the average sizes of the rooms where you spend the longest hours and purchase right model of air purifier accordingly.

Which is better – air purifier or air conditioner with built-in air purifier?

People often perplex that whether they really need an air purifier or an air conditioner with built-in air purifier is enough for them. AC with good filtration system will be able to sense and remove PM 2.5 pollutants or at the most PM 1 level pollutants (like in case of LG ECO convertible 5-in-1 air conditioner). Unlike air purifier, AC neither have HEPA filters nor they can be placed into it; hence nano particles in contaminated air cannot be removed. It is judicious to buy an air purifier if you are living in a metro city with poor air quality index. People living in small towns and villages, where AQI is good or moderate, can rely upon air conditioners with good filtration system.

Which is better – air purifier or air humidifier?

Another rival for air purifier is an air humidifier. As the name suggest, the job of an air humidifier is to add moisture into air by synchronizing and converting the water into water vapors. Humidifiers make the indoor air pleasant and comfortable for people suffering with dry throat, nose, lips and skin. But they do not purify the air, nor do they come with any filter to remove pollutants. If you are living in an area with dry air, you can consider buying an air purifier with humidifier.

Which air purifier is best for my house?

You need to look upon various factors before buying an air purifier. Here’s the buying guide to help you to choose the right air purifier for your home.

  • Determine your needs – Do you have any specific need to buy an air purifier? If you are willing to buy an air purifier for allergy or asthma patients, then consider buying the one with multiple filters, including HEPA filter, for allergen removal. Some air purifiers are specifically designed to remove pet hair and dander, smoke (especially tobacco smoke) and multiple chemical sensitivities.
  • Size of the room – This is the most important factor to choose best air purifier. Consider the area of the room (or average area of the rooms) where you want to use the appliance. Air purifiers are meant to have good coverage area and high CADR. Higher the CADR, faster and efficient the appliance is. The Minimum recommended CADR for a room up to 300 square feet is 140.
  • Operating cost and maintenance cost – Power consumption and cost of replacing air filters must be considered before buying an air purifier. Activated carbon filters normally last for 6 months and costs around Rs. 1000- Rs. 3000 whereas HEPA filters generally last for 2000 hours and costs Rs. 3000 approximately. Also, check the easy availability of spare parts in the market.
  • Noise level – Choose an air purifier that makes less noise. Noise level of a library is 40db. Any sound quieter than 40db is unlikely to get noticed.
  • Air Change Rate per Hour (ACH) – ACH refers to the number of times the appliance purifies the air in an hour. Recommended ACH is 4 which means the appliance will purify the air after every 15 minutes.
  • Other factors – Reputation of brand, automatic monitoring, warranty period and weight (if you are willing to move the device from one room to another) are several other important factors to consider before purchasing a new air purifier.
