There are a number of air filtration solutions on the market. Unfortunately, some have unsubstantiated claims.
COVID-19 has not proven to be airborne at this time...however more information is suggesting that transmission can be greater through the air than through close contact.
Should you wish to install air filtration in your home here is what we use in our own homes.
Room:
The best by far is a portable HEPA filtration system that can be located in a specific room where you or your family member are isolated from the rest of the family. This will keep airborne allergens and particulate at ultra low levels.
Whole House:
If no one is sick or is suspected of having the virus, then a whole house filtration system is the best way to keep all rooms in the home clean.
We use the Bionic Air Screen Electronic Furnace filter system along with the Bionic Amaircare Central HEPA Filtration System.
