Here is an interesting article on effectiveness of simple masks at filtering small particles such as Covid-19.

They have found that bandana made of t-shirt like material still allows droplets to travel 3 feet 8 inches.

There are still KN95 masks for sale on Amazon. As Bart suggested, research the sellers well. There are many instances of buyers not getting masks that filter 95% of the minuscule particles out as a true KN95 mask should. There are also the American N95 or the European P2 or P3 masks which are probably very difficult to find still.
