Did you settle on an air filter? The obviously scammy industry always turned me off every time I looked in to them.

The big Honeywell cylinders w/ charcoal filters. https://www.amazon.com/Honeywell-50250-S-True-HEPA-Purifier/dp/B00007E7RY https://www.amazon.com/Honeywell-50250-S-True-HEPA-Purifier/... At one point a couple of these handled 6 cats and 5 ferrets. The scammmy stuff made no dent. Commercial use hotel + mold ozonaters worked, but unsafe.

Not OP but I've also researched this topic and settled on an iqair filter back when I lived in China. I did borrow a particle monitor and the drop in the number of particle was flagrant when turning it on. Subjectively it also did a lot to improve the air in the house... I'm not sure that something like an iqair is needed in a place that isn't as polluted as China (we sold our air filter when we moved out)

I did. Ended up going with a 'Rabbit Air Minus A2', which I think mostly uses components from a popular Korean brand (can't remember the name). Good customer service too; they've been pretty accommodating given I'm in Australia. With air filters, although there's a lot of 'magic beans' out there, it really just comes down to having good quality physical filters (usually multiple ones in sequence, like particle, hepa and carbon) and a decent 'clean air delivery rate' (CADR) given the size of the room. Heck, you can make a reasonable homemade air filter (that has measurable effects on air quality) by strapping a large HEPA filter to a box fan (although be aware that this could have safety issues re: fire hazard). Steer clear of anything that puts O2 into the air that's anywhere near EPA approved 'safe' levels (which are probably still too high). Some folks use O2 generators for mould remediation when the house is unoccupied and subsequently ventilated (known as 'ozone shock treatment'). However, I think even this is a potentially dangerous practice as O2 will react with other things in the room as well (e.g. furniture varnish), potentially releasing volatile organic chemicals (VOCs) into the air. When I get back from work I'll try and dig up a really good review site I stumbled across. It's one of those gems where the author is clearly just really really into air quality, and who has a very good nose for BS 'science'. EDIT: Oh, also, another good option to deal with some VOCs (like benzene) are certain kinds of houseplants. NASA studied this so there's a fairly credible list of plants to choose from: https://en.wikipedia.org/wiki/NASA_Clean_Air_Study https://en.wikipedia.org/wiki/NASA_Clean_Air_Study EDIT2: Also, assuming you don't live near a major highway or something, one of the best things you can do to improve your indoor air quality is open a few windows and blinds. EPA studies suggest indoor air quality is usually far worse than outdoor air quality. And opening blinds lets more sunlight in, which will retard mould growth. And it's all free. Free!
