HVAC and COVID19 Webinar - Long Version
Channel: Nate the House Whisperer
Date: 2020-03-23

We're spending a lot more time at home thanks to COVID19. Retrotec and I put on this webinar 3/20/20.

We breathe 3000 gallons of air per day, now most of them are in our homes, thankfully there's science that suggests we can reduce the risk of viral spread with a few simple tools which are discussed at the end of the webinar. 

These are NOT absolutes, but they do look to reduce risk of transmission while carrying very little downside risk.

1. Humidity control - 30-50% relative humidity is a sweet spot to reduce viral spread in earlier studies. 60% max. Use a humidifier or dehumidifier to accomplish this.

2. Filtration - viruses spread in very small droplets or aerosols, some of which can be caught by high end filters. An effective filter can be built for under $100.

3. Fresh air - bringing in recommended fresh air levels was found to be the equivalent of 50-60% inoculation. 

Those are the broad strokes, they are NOT absolutes. The details are in this webinar.

Also, if you have been pitched an ultraviolet (UV) light product, please be careful. 

Certain products can cause more harm than good while the 3 methods above carry little to no risk with some odds of helping. 

Dr. Shelly Miller of University of Colorado, Boulder discusses how UV products work.

This webinar goes quite deep, but is fairly long, I'll record a shorter version as well.
