Until it's widely accepted that #COVIDIsAirborne AND we have widely implemented the triad of engineering indoor controls of #ventilation, #filtration, and #UVGI this won't end.
The analogy is municipal water treatment and sewage treatment to stop cholera.

If I may turn this into a short, punchy statement:

We stopped cholera by cleaning the water we drink.

We will stop Covid by cleaning the air we breathe.

@neroden @DavidElfstrom I've said many times that there are no silver bullets to resolve a viral pandemic. Yes, air filtration would help tremendously, but this is but one part of the plethora of parts required to resolve this pandemic.

#HEPA filters and #CRboxes #CleanTheAir; #masks (#p100, #n95, etc) also clean the air (immediately before you breathe it).

The evidence says that enough filters + enough masks *will* end the pandemic. Ask Apricot Tree Cafe or Abrome Ed -- or see the Cambridge hospital study of HEPA filters.

@MozzieBytes @DavidElfstrom

Is this a "silver bullet"? I wouldn't call it that given that it's more like an arsenal.

You have to build a WHOLE LOT of air filters, just like we had to build LOTS of water treatment plants.

Air filters for all buildings are actually cheaper than water treatment plants for everyone though.
