Purify vs Sterilise: What’s the Difference?

With the current COVID-19 situation, we have seen a lot of air purifiers being rolled out into the market. Each model and brand has similar or varying properties depending on how they are marketed to the world. But did you know that most of these so-called air purifiers aren’t really effective in the crisis that we are facing today?

Most leading air purifiers boast of their super-effective properties against tiny PM 2.5 dust particles and other allergens in the air with up to 99.95% efficacy. Yes, all of these claims are true because they use HEPA filters that are made from very delicate fibreglass and are great for filtering out tiny particles.

However, if you think that 99.95% efficacy in an air purifier is enough to keep you safe from COVID-19, we regret to inform you that you might be wrong.

Purify vs Sterilise: 99.95% is not everything

Efficacy levels of air purifiers against viruses and bacteria are known as log reduction. They are divided into six levels as below.

Log 3 indicates the level of “sanitisation” that is generally found in most hand sanitisers and soaps. Most leading air purifiers are up to 99.95% effective (log 4) which is considered to be the level of purification.

But when it comes to log 6, you can see that it has an efficacy of 99.9999% — easily the best of them all. And believe it or not, we have now brought in this level of log reduction to the market. Let us introduce you to VIRUSKILLER™

VIRUSKILLER™ can kill up to 99.9999% of airborne viruses and bacteria

On paper, the difference between 99.95% and 99.9999% might not seem like a lot - in fact, just a few decimal points apart. But in practical comparison, we can tell you that they are miles apart!
