About Room Air Purifier

Air purifiers and particle filtration
Coronavirus particles do fall within the particle-size range (0.01 microns and larger) that HEPA filters, found in some air purifiers, capture.
An air purifier could therefore capture coronavirus if the device had a particular type of HEPA filter, with an efficiency of 99.95%, and an ultra violet (UV) lamp to then kill coronavirus.
Crucially, though, in the real world, a lot depends on factors such as:
the type of HEPA filter you have
the size of your room
the frequency of air changes in that room
ventilation and airflow patterns within the room
the state of the filter
whether your air purifier is an older model with a fading UV lamp.

What does the science say about air purifiers for Covid-19?
At the start of the pandemic, there was - as you'd expect - little to no evidence about the efficacy of air purifiers against Covid-19.
As you'd also expect, there has since been research carried out to investigate just this matter.
In November 2021, a research team at Addenbrooke's Hospital and the University of Cambridge reported that they were able to use HEPA filter/UV steriliser air purifiers to remove most airborne traces of SARS-CoV-2 on surge wards at the hospital. The air purifiers also successfully filtered out other bacterial, fungal and viral bioaerosols (airborne particles containing living organisms). However, it's worth noting they used a HEPA 14 filter (which is medical grade) in the air purifiers, rather than HEPA 13 filters, which are more commonly used in consumer appliances.
And a July 2021 report from the Centre for Disease Control (CDC) in the US also suggested that portable HEPA air cleaners could reduce exposure to SARS-CoV-2 aerosols indoors. However, it focuses on conference rooms, not household environments, and used a simulated environment.
In short, there's a lot more real-world evidence needed - and the results of these research studies don't change our advice about air purifiers and Covid.
