GermGuardian - AC3000 Series (AirSafe+)

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..

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.

Thirding the Coway rec. Replaced all my freestanding GermGuardian HEPAs a couple of years ago because the filters were too expensive and needed too frequent replacement. I do use Coway branded filters, which are pricier than third party knockoffs, but they cost less than the old GG ones and only need replacing once a year. I run mine at level 2 speed 24x7, no issues. Highly recommended.
