If this is your house, consider putting in an exhaust fan to expel litterbox smells & 3D printer fumes. I have a cheap shower fan on a motion sensor yeeting all of kitty's litter dust and fresh-poop smell out of the house. Makes a huge difference.

3D printer should be in an enclosure at the very least. If you're printing any exotic materials you should be venting that out as well as certain filaments can produce toxic fumes.
Austin air is the only way to go, IMO:
15 lbs of activated charcoal
60 sq ft of hepa material
I replace my filter once in 5 years.
Not too bad. I change mine once a year.

Thoughts on this vs Winix C909 that was $160? I mean I know Conway is super popular, $350 just seems like a lot. Square footage is overkill for my basement but with litter boxes and 3D printers it can still get pretty ripe down there

Don't vent litter but do vent 3D printers. Unfortunately litter boxes are significantly distant from any window. And even with an enclosure and exhaust printer smell still travels around the room just through regular use.

I run a Germ Guardian and a Winix C545 in the basement 24/7. Perhaps try a Winix C545 ($70 or less refurb that comes around often) to see if it helps.

I bought the Airmega 400 last time when there was a coupon that bought the price down to $332 a month ago. I run it on the main level, and I like how quiet it runs. I have a couple of Airmega and Winix around the house.

replacement filters usually pop up on here for ~$78 and they're generally good for at least a year in my experience

Also, this thing says it can be set to "eco" mode to turn off and on as needed. That is really hard on the motor. I set my austin air to medium speed and it just runs 24/7. Had it 30 years now without issue.

What are you talking about? Maybe for 4 of them. You can buy a set (2) which is all you need for $31 right now on Amazon.

Ahhhh. I see that now as Amazon is recommending sponsored non oem filters. My bad for seeming harsh and your price was correct for oem. Best price I got for oem was $65 for a pair through Walmart.

I just replaced my filters with an aftermarket brand. $32 for the pair.
