NOW, they are telling us that we aren't safe at home, to wear a mask EVEN There?? Do these Idiots not know that a Merv 13 AC Filter Catches and Kills all viruses that are sucked into the Return Air Closet? AND that every breath of air we breathe passes through this filter; Continuously? Why is no one mentioning this? Schools can be OPEN, Offices, everything. Just install these filters in every AC System. Men, Go to Costco, Home Depot, Amazon, ect, and purchase a pack of the best filters you can buy. PRICEY? Yep, but how much is Health and Piece of Mind worth? MERV 13!! No charge for the heads up.
