GermGuardian - CDAP5500BCA

Yes have same one and been running 24/7 for over 15 years loveee it. Just bought the larger 28 inch model wish would have years ago! You can see it pull smoke across room- this brand has never let me down!  Love how they have four types of filters too!  Regular, smoke, pet, and toxin options.

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.

GermGuardian is my favorite! Has a HEPA filter that is super easy to replace, UV-C, and odor control, and they also have some models with carbon filters, and is very quiet. I have one in my office and one at home and love them.

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.
