Can air purifiers cause breathing problems?

With deteriorating indoor air quality in urban areas, indoor air purification has become a necessity. With these existing problems air purifiers have gained a lot of popularity. 

Air purifiers are devices that trap air borne particles, dust, pollen, volatile organic compounds; including paint, pesticides, household cleaning products etc. These pollutants are known to cause certain respiratory diseases and other health problems. 

Indoor air purifiers are highlighted as a major solution to the problems related to poor indoor air quality. It is true but only to some extent. 

In this article we will discuss some negative impacts of air purifiers on our health, we will tell you which type of air purifier is safe for you, and also we will recommend some air purifiers which are completely safe to use. So read the full article to know. 

How can air purifiers cause breathing problems? 

Some air purifiers like ionic air purifiers generate a toxic gas called Ozone. The ionic air purifiers work on a principle that the metal electrodes charge the airborne particles and attract them electrostatically. This process is known as corona discharge and  results in the emission of ozone as a byproduct.

Inhalation of this toxic gas can result in increased risk of respiratory infections. In Fact Ionic air purifiers can even make conditions like asthma worse.

What are the negative impacts of using an ionic air purifier?

The ionic air purifiers do not remove the airborne particles from the ambient air. Rather these particles just stick onto nearby surfaces and even  our windpipe, alveoli and air sacs of lungs. This aggravation of pollutants can cause certain heart, lung and other respiratory conditions.

These Ionic air purifiers also produce toxic ozone gas that can aggravate in the indoor air upto critical levels. This can cause certain health impacts like: 

  • can irritate the lungs
  • trigger asthma attacks
  • damage your olfactory bulb
  • Can cause throat irritation
  • Coughing
  • chest pain
  • shortness of breath

Which air purifiers are safe to use? 

Air purifiers such as high-efficiency particulate air (HEPA) filters are a solution to this problem. HEPA filters are efficient at removing 99.97% particles, ranging between 0.3-0.1 microns without generating harmful ozone. 

Working of HEPA air purifier

HEPA air purifiers work on a principle that the contaminated air is drawn into a unit, where it traps the particles inside. The clean, fresh air is then being emitted into the room. 

This process works continuously in a cyclic manner to produce fresh air. 

And due to this reason, these air purifiers are considered as one of the best filters for people having respiratory issues like asthma.
