Best air purifier protection COVID virus

Air purifiers have become an obvious for those looking to protect themselves from the COVID-19 coronavirus. That’s not surprising. Data shows that air purifiers can filter COVID-19. In fact, the EPA now suggests portable air purifiers be used to improve ventilation to protect against COVID-19:

However, when looking to buy an air purifier, the wide range of filters, makes and models of air purifier can be daunting. What’s more, finding the best air purifier can be made more difficult by companies using misleading marketing strategies and flashy ads.

This article covers the best air purifiers for combating the COVID-19 coronavirus. It gives instructions on what type of air purifier is best for COVID protection, and provides simple steps to choose the best air purifier for COVID-19.

 

Best Type of Air Purifier for Coronavirus Protection

There are three main types of air purifiers that have been marketed as best for combating COVID-19. They are:

  • UV Light Air Purifiers
  • Ionizer Air Purifiers
  • HEPA Filter Air Purifiers

We’ll go through each in turn, using data to show which is the best.

COVID Protection #1: UV Light Air Purifiers

UV air purifiers have been mentioned by some as the best air purifier for COVID-19 protection. Data shows that UV light can kill the coronavirus, so UV light air purifiers seems like an effective way to kill viruses such as the coronavirus in the air.

However, data shows that the UV lights in most UV air purifiers are too weak to kill viruses. This means that for a typical household UV air purifier, viruses in the air would have to pass 36 times through the purifier before 99.9% of them would be killed. That’s not very practical.

Other downsides to using UV light air purifiers to combat COVID include:

  1. UV light air purifiers typically cost more than other purifier types (both for the purifier, and for the electricity used);
  2. they can lose their effectiveness rapidly, as the light gets dirty.
  3. UV light itself is dangerous – especially to the human eye.

All in all, UV light air purifiers aren’t the best purifier for COVID-19.

 

COVID Protection #2: Ionizer Air Purifiers

Ionizer purifiers are another type of air purifier that some have said is best against COVID. They work by shooting negative ions into the air. These negative ions stick to viruses, and in turn sticking them surfaces like walls and tables. The science is similar to what makes a balloon stick to the wall:

This is an important point for ionizer air purifiers. Because the ions only move the viruses to walls and tables, the virus is still in the room. Ionizers do not kill or remove the viruses from the air. What’s more, these surfaces could become a means of transmitting the Covid-19 virus.

Conclusion: Coronavirus: 1 – UV light air purifiers: 0

Since ionizer air purifiers do not actually remove viruses from the air, they cannot be considered the best air purifiers for COVID-19.

 

COVID Protection #3: HEPA Filter Air Purifiers

If you’ve read this far, you probably already know which type of air purifier is the best for protecting against COVID-19. HEPA filter air purifiers have been around for a long time. And there’s a reason for that. They do a great job of capturing tiny particles, including nanoparticles as well as particles the size of the coronavirus.

What’s more, as HEPA filter air purifiers are simple, old tech, they don’t cost a lot of money. They can be picked up for as little as $30, or you can even make your own. This makes them one of the best choices for filtering out coronavirus.

HEPA filters are incredible efficient, they capture over 99% of virus-sized particles in a single pass. The viruses stick in the HEPA filter, and are no longer in the air. HEPA filter air purifiers also do not release any harmful or dangerous pollutants, such as ozone (from ionizers) or UV light (from UV light air purifiers.

While HEPA filter air purifiers are the best air purifier for COVID-19, they still aren’t perfect. There are some important things to remember when using an air purifier for COVID proteciton.

Bottom Line: The Best Air Purifier for Capturing the Coronavirus

HEPA air purifiers beat ionizers and UV light air purifiers as a practical way to filter and protect against the coronavirus. They can capture over 99% of viruses in one pass, and are low cost and easy to install.
