Effectiveness of cabin air filters and A/C on transport aircraft

Tue May 12, 2020 5:20 am

About a week or so ago, there was a fairly contentious thread about how good or bad filters worked on current aircraft. The OP was some obstinant regarding their effectiveness even when several posters, my self included, tried to explain the current generation systems. There was a small article in AWST which was very interesting. Have a quick read and I hope the person I am referring to does too!! ... protection

Thanks, a good piece. Below is another article about air changes. I am surprised how high the air changes per hour is in the airplane. Hospital recovery rooms require 6 changes per hour with 33% of the air being fresh & 67% recirculated. Normal offices are at 3 air changes per hour with 18% outside air. Surgery Centers don't use HEPA (99.96% of micron sized particles) but use N95 (95% of micron sized particles), in the US these are MERV-14 filters.
