Air purifier is an appliance that cleans the air of a given place. It has several filters and fan inside that is used to clean the air of mostly an indoor room.

 

Why air purifier is needed?

An average adult inhales and exhales about 7-8 liters of air per minute when resting. This amounts to a total of around 11,000 liters of air per day. And we all know how the air has polluted in recent times, thanks to the rapid increase in vehicles, agricultural practices, and industries.

Your best defense against indoor air pollution is to try to avoid having pollutants enter your home or office. Air pollution causes disastrous effects causing Respiratory and heart problems.

Some people have myth that if you have an AC then they may not require an air purifier. “Air conditioning and air purification are two different concepts, while an AC just circulates dirty air, a purifier eliminates harmful particles and odors. Air conditioning has got nothing to do with air purification as it is ineffective against dust and pollen.”

If you think that you are spending most of the time outdoor and buying an air purifier may not be a good investment, then you are wrong, indoor air quality is up to 10 times worse than outdoor air quality because closed spaces enable potential pollutants to build up more than open spaces do.

But determining whether an air purifier is effective is measured by its ability to capture particles and the amount of air it can process in a given time. Air purifier removes up to 99 percent of airborne bacteria.

Air pollutants are mostly of PM10, PM2.5, and smaller particles. PM10 particles are removed by pre-filter whereas PM2.5 and other small particles are removed by HEPA filter. Some of the air purifiers also have additional filters such as UV filter, antibacterial filter, etc.

Air purifiers are very useful in a house where people suffer from asthma, allergies, and also protect newborn and pregnant ladies from harmful air pollutants. The activated carbon filter in the purifier helps to remove odors.
