Good luck with the spraying. Will prove totally non effective if the virus is spread thru ‘common’ A/C Heating vents. This was reported on Fox yesterday. Restricting H/K residents to their 1000 apartments in one building makes for one large petri dish.

Installing Hepa filters in the vents will help to control aerosol spread. The biosecurity research labs (like USAMRIID) use Hepa filtration to scrub the air before it leaves the high containment suites. I'm not sure if Hepa filters are sold at the local home improvement stores, but might be available on line.

The HEPA air filters are available at Big Box stores, but a) they are more expensive b) if they don’t seal well, their effectiveness is greatly diminished.

AprilAire makes very good whole-house HEPA filters. I've installed them in two houses. It requires an HVAC contractor to modify the air duct at the entrance of your furnace, but it's not a big or complicated project.

This Model 5000 unit combines an electrostatic filter and a non-woven deep-pleated paper filter (very unlike your typical furnace fiberglass filter).

Even so, no filter traps 100% of all airborne particles. This unit captures 98% of airborne bacteria-sized particles and fungi; 80% of airborne virus-sized particles and ultra-fine particles — down to 0.01 micron in size and 99% of airborne pollen, mold, and spore-sized particles less than a micron in size.
