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..

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.

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.
