Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Please don’t take advice from here, find out for yourself: Buy an air quality monitor like the one pictured, https://preview.redd.it/gpgkactfh3sg1.jpeg?width=1320&format=pjpg&auto=webp&s=4cdc97dbace6cdeaaca5d25c067fae91e5558927 with VOC, CO2, etc. and depending on which spike for your room, buy a hepa air filter with the matching strength, eg my small farm of X1Cs emit a lot of PM2.5 and TVOC so I got a Levoit that handles double the sq ft of the room and though it has its own detection, I just run it whenever I print. It’s quiet and avoids the issue. But there IS AN ISSUE. It’s different for every space, room, ac system, printer, filament, project etc. You have to sample YOUR air.
levoit is good and has some very affordable options. we have an appropriately sized levoit in almost every room in our house and it helps a lot with allergies. also make sure to change your furnace filter regularly and use merv 13 or higher filters for it
I have this setup. The Google home options to control it are limited. I just end up using their vesync app for scheduling. I do use Google home with it to setup automations for bedtime and stuff.
I’ve been running Levoit air purifiers for years non stop now. I’ve never had any problems.
I have had Levoit for a long time and they work well. Granted, if I was in the market I might do more research as it turned out my models weren’t “true HEPA” as advertised.
Seconding Blueair! We have a Levoit and a Blueair; while I have nothing bad to say about the Levoit, I personally prefer the Blueair (granted, it was about twice as expensive). We've got two medium-sized dogs, and - aside from the clumps of dog hair under the baseboards - you wouldn't know that we had any pets!
