This video consists of four parts. One part is a review of my Honeywell Hepa air filter model 50250-S and the terminology used to describe and rate HEPA filters, the second is a list of criteria used to select a home air filter, the third is a discussion on my views of using a HEPA air filter to reduce at-home exposure to the virus by filtering out airborne aerosols that may contain the virus and the last and fourth part is a discussion on a NASA study on HEPA air filters. The NASA study appears to show that by reducing the speed of an air filter its effectiveness at capturing particulate matter can be greatly improved and also how a filter rated at 0.3 microns may actually under certain conditions trap much smaller matter than the filter is rated at.
I no longer see the 50250-S for sale. I am not going to give you a list of air filters, but If I were to buy another Honeywell air filter I would get the one below. It is renewed (refurbished) and sold by Amazon so if you are a tightwad like me the price saving is good and it was highly rated on Consumer reports..
Honeywell True HEPA Allergen Remover, 465 sq. Ft, HPA300, Extra-Large Room, Black (Renewed)
