I use [this](https://www.homedepot.com/p/GermGuardian-870-sq-ft-HEPA-3-Speed-Tower-Air-Purifier-28-in-in-Black-for-Home-UV-C-Wildfire-Smoke-Dust-Odors-Allergens-AC5300B/206868649) purifier with their pet filters for my bird room. Filters last about 6 months, but it got my cockatiel to stop sneezing all the time.

For less than that I got two germ guardian hepa air filters, and a Bissell hepa vacuum.

Germguardian, not sure about for life. But they warrantied one free of charge, paid for return shipping and all. Filters aren’t crazy, and you can see the work they do. I have no measurements for it, but I like em. They all are essentially just motors and fins.

I have 2 winix and 1 Germ guardian they both work well. Slightly favor the winix. I change the filters every 6 months. Couple tips- 1. Buy cheap bags an amazon and swap it out daily 2. Buy charcoal granules and put them in the waste bin - if you do this you can swap the bag eod. They absorb smell https://a.co/d/0a1CxSgw 3. Keep a window on each side of your home slightly open. This does wonders for keeping air flowing and getting rid of smell.

I currently have 2 Winix and 1 germ guardian. They are both good but if I had to choose I would go with the Winix. The pre-filter does a great job collecting debris and dust which I think helps the HEPA last longer. I changed my filters twice a year and I use the genuine filter. https://a.co/d/4e6aipw

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 do. I have 3 school aged kids aka plague carriers. We have Germ Guardian UV-C plus HEPA filters in each room. It greatly cuts down on kids reinfecting each other and us parents. They also collect cat hair pretty well. The Germ Guardians were $98 each and 4pack of replacement filters is $30. Saving one doctor visit for the 3 kids covers buying a unit.

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

They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.
