We can't stress enough how important noise is when purchasing air purifiers. Manufacturers of air cleaners are notorious for promoting the Clean Air Delivery Rate (CADR) or Airflow on top speed, but noise on the lowest speed.
This means that you'll calculate how many air changes you need for your size of space, purchase an air cleaner, then run it on a lower setting giving you much less clean air than you thought you paid for.
If you don't factor in noise, you will find it turned down or off...
- Turning down delivers less clean air
- Turning off gives you an expensive white box
Smart Air portable air cleaners are designed for quiet operation at maximum efficiency
On top speed, the Blast delivers 950m3/hr CADR at noise levels of just 43dBA making it the quietest commercial air cleaner in the market!
We checked X/Twitter for comments on air purifiers in hospitals. We were really surprised how many units weren't on. We even found a comment from an Addensbrooke doctor where awareness should be highest due to their ground-breaking research in surge wards where zero SARS-CoV-2 was detected on all air purifier testing days!
