GermGuardian - AC3000 Series (AirSafe+)

I’ve tried a few and the germ guardians are the best bang/buck. The big Honeywell ones if you have to do a BIG space. We have a Dyson and I don’t love it.

I have a vertical germ guardian at the back of our LR4. I don't want it too close to the opening as it'll suck in too much dust and prematurely clog the filter. I wash the prefilter once a week..

With that in mind a germ guardian tower is probably the most affordable good option. Whatever you buy should have UVC light built in to degrade mycotoxins, “plasmawave” or “bipolar ionizer” is also an acceptable alternative just make sure it’s California CARB certified. Stay away from classic ionizer/ozone

I've got three Guardian HEPA towers. The oldest is seven years old now, and they still work great. I vacuum the charcoal filter once a week and change that and the HEPA filter about every six months.

I have used ALEN and GermGuardian HEPA, I got the GG first and ALEN as a second one later. They definitely do something, I lived in city during first part of my pregnancy and the smells and air quality were stifling to me, so I bought one and it was a huge improvement as I could actually tolerate the air in my apartment without feeling sick. They filter noxious smells pretty well, I used to live with people who smoked 🍃and I was able to keep the smell out of my room with it, so it definitely did something. I always see Austin air and air doctor recommended, and some specifically for issues like mold. Idk if it’s hype, like someone said you could get a box fan and air filter and make your own. But, Air Doctor is doing a presale on their new model at half price so it’s around $400 instead of $800, but doesn’t come out until summer. I just bought it as i need one for other room and thought id see if it makes a significant difference compared to the ones i have.

Blues air or GermGuardian with UV. I’ve had mine for years and it’s been great
