After reading this article when it was posted in 2022 and the author's other post on particulates[0] I bought the sqair[1], which we are very happy with. Allergies and morning congestion are nearly 0 after using it. We live on a very busy road so I run it all the time and with the carbon filter as well. I would like to get a second one eventually -- it only cleans 430 sqft of air and our condo is 730.

An issue I've found is outdoor air ventilation vs. air filtration vs. humidity management is a tricky thing to balance overall when you don't have a central HVAC system with an ERV installed, especially when you live near a busy road or have allergy issues. If you add a CO2 monitor to your air monitoring, you'll start to see where this becomes a hard thing to balance without a large ERV or other specialized ventilation systems. On top of that, living near a highway might not show issues on your PM2.5 / PM10 monitor, but it still shows in health statistics according to studies.

  I assume it shows up on health statistics because virtually nobody has multiple MRV13 filters in their house running all day. They probably don't even have a decent air filter for their homes AC.

  ERVs are crucial for keeping CO2 and VOCs low. You can install one in a window! https://gen.co/air https://gen.co/air

After reading all this talk about HEPA filters and 99.95% vs 99.5%, it's funny to read on that Sqair page "H12 HEPA (99.5%)". There's no such thing as H12 according to that wikipedia page for HEPA standards.
