Honeywell - HPA060

So the winix has the ionizer which produces ozone, a lung irritant. I actually bought this model and ended up returning it because of this. Also it’s enormous. I know the levoit is a popular brand but haven’t personally used it.  I’ve had my Honeywell HPA060  going on 6 years now and have been happy with it, though I wouldn’t replace it if it broke, because my r/crboxes do a much better job and it costs less to replace the filters. 

Just stay away from the Honeywell HPA models. They all develop a burning smell. I've swapped my 2 out a total of 6 times.

That looks like a nice air purifier! And looks like they were trying to copy Blueair in the looks dept :-) . I personally despise Electrolux AB though.....bought an Electrolux UltraCaptic bagless canister vacuum in 2015 for messes I don't want to use my bagged canister vacuum on. Within 6 months of buying it, went to go buy spare filters and they were already discontinued!!! And this wasn't a cheapie from Wal Mart either - this was a $700 machine. I much prefer and use my Aerus Electrolux 6500SR bagged canister on a daily basis, and that machine will have EVERYTHING parts wise for decades to come. As for air purifiers, I have a Filter Queen Defender and a couple of the old Honeywell round HEPA air purifiers that work well in my household.

Yes, an air purifier helps. The best brand is Honeywell with a HEPA filter. Second is Bionaire with True HEPA filter (purple one), third is Bionaire with the blue filter. Levoit kind of sucks. Don't waste your money on the Pure Enrichment Personal Air Purifier.

Honeywell Hepa Air Purifier is amazing all the time especially post fire. It's saved me.

Honeywell HEPA. Don't buy an electrostatic/ionizer type "purifier" as it creates O³ (ozone) - which is hazardous (and is also a component of smog).

Honeywell HEPA is what I’ve used for decades. Reliable and easy to find their filters.

You can get a HEPA filter air purifier (Honeywell makes decent ones) to deal with PLA and TPU, they dont emit the toxic VOCs like ABS, Nylon and PC, but they do still emit fine particles. Having it enclosed like you do is going to prevent a lot of those fine particles from scattering through the room though so its a big help. As a rule I try to not have my printers in the same room I work, but if you must, that HEPA filter will help reduce the fine particles a lot. For the more toxic materials, absolute best bet is to create a negative air pressure environment while venting outside through a window or port. If you cant or want even more reassurance, running a carbon filter does a lot to help. There are specialized air purifiers for VOCs but theyre not cheap. A really good one you can get is from Heygears, called the GreenPrint Purification Unit. Just know it's specifically for VOCs as it doesn't trap particles, it destroys them (so you still want a HEPA for the fine particles). This air purifier doesnt need filters though, it doesnt trap VOCs like a carbon filter which can become saturated and need replacements. It actively breaks down VOCs, so it just runs indefinitely with full efficiency, no need to swap filters.

Honeywell HEPA air purifiers. I have two: one in bedroom and one in the room where I spend most of my time watching TV, etc. Makes a difference for me.

I have these, as well, and they’re great. The cheap after-market filters from Amazon work perfectly for them, too.
