A:Answer Hi there Dee, this is Tia from Dyson. With regard to Dyson purifiers, we haven't tested our units with the COVID-19 virus specifically. We highly recommend using purification if you can, as many of us are spending much more time inside our homes, generating indoor pollution from cooking, cleaning, from wood-burning stoves etc. and purifiers can remove those pollutants from the indoor environment.
Dyson purifier fans removes a range of contaminants from the air and purifies to remove 99.97% of allergens and pollutants as small as 0.3 microns from the home. It also removes pollen, pet dander and odors such as cigarette smoke and cooking smells.
When it comes to minimizing the risk of getting COVID, following government and public health guidance is imperative.
Thanks for your interest in Dyson technology!
Best wishes,
Tia
