Few realize that indoor air can be 2-5 times more polluted than outdoor air. Hence below mentioned list of Best Air Purifiers are designed to ensure that we breathe cleaner, healthier air indoors.
We take 24,000 breaths a day & breathe in roughly 13-14 kgs of air, which is 7 times more air than the food we eat or the water we drink, yet the air we breathe is taken for granted. Though occasional hazards like smog and visible air pollution catches our attention, the issue of everyday indoor air quality often goes unnoticed, especially indoors at our homes or place of work.

Room Air Purifier : Used indoors, this type of air purifier is capable of cleansing the air in large areas like a room.
Car Air Purifier : Designed to be used in an enclosed vehicle and capable of cleaning the air of pollutants, allergens and dust. Designed to be compact and portable, they usually run on electricity and are plugged into the cigarette lighter receptacle for power.
One should should consider below vital factors, so as to have a basic information on technology and features involved when a buying a best Air Purifier for your home or offices.
HEPA (High Efficiency Particulate Air) Filters efficiently clean allergens such as pollen, animal skin and dander, mold spores, and dust. HEPA filters remove at least 99.9% of all the particles as small as 0.3 microns.
Air purifier using HEPA filters have to be periodically changed.
HEPA certified filters work well for all common particle allergens, but remember not all HEPA filters are created equal.
The larger the HEPA filter, the more particulate it will be able to remove. The size, material, and construction of the actual filter plays a vital role in the air purifier's performance.
Activated Carbon Filters are rarely used by themselves, but are often used in combination with other filters.
This filters help in absorbing odors and gases thereby neutralizing smoke, chemicals, and fumes.
Reacts with oxygen to open up millions of pores that are capable of trapping a large amount of gas and odor.
This makes it the ideal surface for bonding with chemical or vapour molecules.
Needs to be replaced once they are saturated for optimal performance.
Antibacterial and Germicidal Filters help in eliminating harmful bacteria and germs.
Using UV filters along with HEPA filters ensures the air you breathe is sterile.
Used in hospitals, kitchens, labs and daycare schools to minimize the risk of airborne infections.
Charged Media Filters combine a particle filter along with an electrostatic charge filter to capture particles as small as 0.1 microns.
They are very efficient in purifying air, but need to be replaced fairly regularly to ensure optimal performance.
Photocatalytic Oxidation (PCO) makes use of a titanium dioxide coated metal plate along with UV light to oxidize and physically break down chemicals during the filtration process.
By doing so larger molecules break down into harmless carbon dioxide and water molecules.
Electrostatic Precipitators function just like charged media filters but instead of using filters to capture particles, the particles precipitate and accumulate on the collector plates.
These plates can be washed clean and do not need to be replaced.
Pre-Filters, like foam and non-woven polyester, eliminate large particles like pet hair before the next stage of filtration.
Some have electrostatic properties and use activated carbon to improve filtration and also remove odors and smoke.
They need to be replaced regularly to increase the air purifiers lifespan.
Ion and Ozone Generators clean the air by forcing impurities to cling to nearby surfaces.
The negative ions combine with impurities such as dust and smoke particles and stick to walls and carpets. They may create dirty spots on these surfaces which need to be cleaned.
Organic particles like bacteria, viruses, dust mites and mold are eliminated by passing air over an inner ceramic plate that heats up to nearly 400 degree celsius.
It works slowly as it relies on convection to keep the air circulating.
The main drawback is that it is not effective against chemical vapors, smoke and other non-organic particles.
Air Purifiers which produce Ozone as their main product/by-product are strictly not recommended.
Filtration technology which is ozone free and uses HEPA and Activated Carbon Filters is more effective and widely used option. HEPA filter based Air Purifiers are the only type of Air Purifiers which meet specific health and safety standards.
When choosing an air purifier, the size of the room is an important factor. Bigger spaces will need larger air purifiers and vice versa. Buy an air purifier that designed to operate in a space that is 20-40% larger than room for optimal performance.
The ACH (or the air change per hour rate) tells you exactly how many times the air purifier filters the entire room’s air in one hour. If an air purifier that has 5 ACH, it means that the air in the room will be filtered every twelve minutes.
A light indicator changes color in response to the indoor air quality, so that you can adjust the fan speed accordingly. A higher-end Air Purifier is usually equipped with an Auto Mode function, which would adjust the speed setting in response to the indoor air quality automatically.
Some newer models are also available in the market with numerical PM 2.5 display. These help you measure and see exactly how bad the air is.
A filter needs to be changed usually after every 12-18 months, so the filters should be readily available. One should always look out for pre and post sale demonstration / installation service option provided by the manufacturer.
As Air Purifier is a costly product and a longer period warranty coverage is beneficial so that you do not face any issues and can be assured that your product runs smoothly for years.
For people suffering from Asthma - Air Purifiers with true HEPA ‑ filters are excellent in removing asthma triggers . Also, Ozone based purifiers should be strictly avoided as ozone released from them is harmful for us.
People who are prone to allergies - Air Purifiers are effective for helping relieve year-round allergies, including allergies from pollen and dust. Models that feature HEPA ‑filter technology trap nearly 100% of allergens smaller than the human eye can see.
Construction Area - A pre filter is a must for people residing in construction areas as there is a lot of dust. HEPA ‑filter helps in removing pollution arising from vehicular emission.
Factory area/area with issue of gases with smell - Activated Carbon ‑filter is a must as it can absorb those harmful gases on it’s surface. Be sure to check the filter before purchasing.
People with pets at home - Activated carbon filters absorb pet odours and produce fresh-smelling, healthy air throughout your home. Pre filter traps the hair and dander
Family members - Young children at home, patients of lower immunity, transplant patients, dialysis & cancer patients, people who want a healthy lifestyle.
Depending on the type of filter, they will need to be changed to ensure consistent purifying of your air. So you always stay on top of it, a filter life indicator automatically alerts you when it’s time to change the filter.
While your air purifier is running, special sensors monitor the air and automatically adjust the cleaning speed accordingly.
Adjust how rapidly you want your air to be filtered with multiple speed settings.
Whisper-quiet operation on some air purifier models makes them ideal for babies, small children, and light sleepers.
Some models come with sensor lights that tell you, at a glance, what the air quality is like in a room.
Clean or replace filters regularly : As a general rule, you should replace them (or clean those that can be vacuumed) every six to 12 months for pleated filters and every three months for carbon filters.
Place it wisely : If you have just one unit, place it in the room where you spend the most time. For most people, that’s the bedroom. Make sure to place the air purifier in a spot where nothing can obstruct airflow—away from curtains, for instance. For more, read our article on how to choose the best air purifier for your home.
Keep your purifier running 24/7 : Keep doors and windows closed while it’s in use. We suggest running the unit on the high setting when you’re not in the room and turning it down to low when you’re nearby. Or buy an air purifier certified for a larger area so that you can run it on a low speed and still have it work effectively.
Vacuum regularly. No air purifiers can remove the larger allergens—dust mites and pet hair, for example—that settle on furniture and carpets unless it gets disturbed and redistributed into the air. Use a vacuum with a HEPA-certified filtration once or twice a week to clean floors and furniture.
Use an exhaust fan in the kitchen. Do the same in bathrooms and laundry rooms.
Stop smoking indoors. That also goes for burning candles and wood fires.
Ventilate. Open your windows on nice days to let in clean, dry outdoor air. If pollen or related allergies keep you from opening windows, run your air conditioner or forced-air cooling system with a clean air filter
Reduce the use of chemicals. Limit chemical-heavy cleaning products, and don’t store paint, glues, or insecticides near your living quarters.
On an average we spend close to 80% of our time indoors (home, offce, etc.), children and babies spend even more time indoors.
With an Air Purifier, you can control the quality of air indoors and protect your family, and it is indoor air which is more polluted than outdoor air as per data sources.
Features like caster wheels, handles for easy mobility, digital controls, remote controls, timer settings, multiple fan speeds may be additional features which one can look for while buying Air Purifiers.
1. Purification is dependent on the quality of the filters. Air Purifiers have very high quality HEPA filters which naturally catch very small dust particles, most bacteria and even some viruses.
ACs with purification system do not have such advanced filters and rely on chemicals to kill bacteria and viruses, producing Ozone which in turn can also be harmful.
2. ACs cannot be run through the year, but you need pure air throughout the year. Even in summers, the electricity cost of running an AC is much more than running a 40-50W Air Purifier
There are a lot of Air Purifiers out there which are advertised as having HEPA filters, but actually don’t. Usually these are disguised as having HEPA-like filters, and don’t meet strict HEPA standards.
Filter life is proportional to the pollutant holding capacity and the pollution level in your surroundings.
TRUE HEPA filter has high capacity, thus the long filter life. A filter will last longer in a relatively cleaner area. In general, filters last for 12-18 months with 6-8 hours daily average usage
Actually, it is the average exposure during the day that is most important for your health.
The World Health Organization defines their guidelines for air pollution levels based on the 24-hour average value.
By breathing clean healthier air inside you can reduce your daily average exposure level and do the best to protect your health.
Air Purifiers are used to clean indoor air, but do not optimize humidity levels. They remove particles, dust, and smoke from the air, as well as allergic substances like animal dander and pollen.
Humidifiers increase the humidity level by distributing water into dry air.
You can. The power consumption is very low, so long usage doesn’t cause a heavy impact on electricity bill.
As compared to an AC which consumes 2000W power, an Air Purifier consumes 1/40th of it (~50 W). So power consumption per hour of an AC is equivalent to 40 hours of power consumption by an Air Purifier.
The filter life is dependent on usage/quality of air and that should be kept in mind
One should be careful while buying Air Purifiers which release ozone, since ozone may cause serious health issues like permanent lung damage or aggravate asthma.
Ozone reacts with organic matter both outside and inside the body, resulting in harmful health consequences.
CADR is specified for the highest speed setting. But users will often use lower settings to reduce noise, and this can reduce the efficiency of an Air Purifier
An air purifier is a valuable investment that will reduce the prevalence of irritants in your home. With all the relevant and extensive information now available online at the glance, buying the Best Air Purifier for your homes or offices shouldn't be a confusing task.
