Difference Between HEPA Air Filtration And Air Ionization

Aug 22, 2018

Are you planning to buy an air purifier for your urban home soon? Well, no wonder about that since our country has some of the most polluted metro cities in the world. Take the national capital Delhi for example. The city dwellers were already facing an yearly onslaught of winter smog and now the summers have also gone the same way with multiple dust storms hitting the region in the past couple of months.

In such a scenario, buying an air purifier makes sense but so does making an informed decision. There are two types of air purifiers available in India today, products that come with HEPA air filtration and products that use air ionisation for cleaning the ambient air. In this post, we help you understand how these tow air filtration technologies work and the one that would be ideal for your home.

HEPA Air Purifiers

These air purifiers work on the simple principle of filtering the ambient air to clean out pollutants. A fan is used to pull the ambient air through vents and the air is passed through several layers of filters to remove the dust, dander, hair and volatile organic compounds. The HEPA filter is the mainstay of these air purifiers.

HEPA filters were first developed to filter nuclear dust in the reactors, so the technology behind them is pretty solid. A good quality HEPA filter can remove more than 99% of particulate matter and other pollutants from the air. A HEPA filter is generally accompanied by a pre-filter and an activated carbon filter for enhanced protection from air pollution.

Air Ionisers

The technology behind air ionisers is a little more complex. These devices release negatively charged ions in the ambient atmosphere, such as inside your bedroom or living room. These ions react with the positive charge of the dust particles and thus stick them to flat surfaces. The concept works in the same way as a balloon rubbed in your hair will stick on the wall or a flat surface.

Thus the air pollutants are removed through ionisation, but the process sometimes releases ozone in very small quantities.

Which one should you buy?

We recommend HEPA air purifiers for some obvious reasons.

  • They remove dust and pollutants permanently instead of just sticking them to the floor and other surfaces.
  • More effective in removing pet dander and hair from the air.
  • Easier to maintain, and replacement filters are available on most online and offline stores.
  • Do not have any side-effects whatsoever in comparison to ionisers which may release ozone, a gas that is harmful for human and animal inhalation.
