The air filter recommendation tool at https://filters.cleanairstars.com now incorporates #ASHRAE 241 IRMM (Infection Risk Management Mode) targets.
It’s important to understand the rated occupancy for your space and use this when entering the number of occupants, rather than how many occupants will actually be present in the space.

See an example here for 15 occupants in a small US retail store context under 45dBA noise level.

Fair. I'll raise the ante and argue that INDOOR environmental protection be an #EPA purview. Pretty clear #cdc isn't going to champion the issue, and it's not just #osha of course.
I'm cautiously curious about how the new #ASHRAE cmte pursues its work. And we mere mortals can't wait 6 months for their recs. I'll have #library #CO2Monitor loan program proposal submitted to East #TN libraries first week of January... Plz contact if interested!

Where are the #IAQ engineer / scientist / PH and other eligible #HealthyAir warriors who will apply to participate on this #ASHRAE #airborne infection mitigation cmte ??
Need not be ASHRAE member.
December 23 application deadline!

Some engineers prefer to use recirculating devices in hospitals, such as chilled beams for the sake of energy savings. I am not favoring at all. Hygiene first. #hospitaldesign #healthcare #mep #hygiene #ashrae #fgi #ashrae170 #microorganisms #filtration #engineers #chilledbeams
