Research at a hospital swamped by people with COVID-19 has confirmed that portable air filters effectively remove SARS-CoV-2 particles from the air — the first such evidence in a real-world setting1. The results suggest that air filters could be used to reduce the risk of patients and medical staff contracting SARS-CoV-2 in hospitals, the study’s authors say.

The study findings have not been peer reviewed. But this won’t stop me from picking up one or two more HEPA’s for the house.

I have been thinking of buying a HEPA filter. Can you post a link to the one you recommend? And does yours have a UV light in it? The one for the bedroom, does it make a nice white noise?
All of our HEPA filters in the house are by Honeywell. A search for Honeywell HEPA will produce an ample number of links for you. Don’t forget to match the size of unit to the square footage of the space you will use the filter in. In the product descriptions you’ll find this data. No UV lights. And the white noise is wonderful. It is louder at higher speed settings but quite the background noise at lower settings. Interesting study, eh?
Very very interesting. Thank you so much!
