AC5300B Elite 4-in-1

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.

It's kind of hard to tell for sure since you get used to the smell of your own house. I will say people have told me they are surprised they don't notice animal smells in my house, except when they are right next to the animals themselves though. So I think I am doing something right. Both brands I mentioned come with charcoal prefilters which absorb odors. The Winex especially comes with like 4 charcoal prefilters per each paper filter, and I find I don't even go through all 4. Another good option for odors is Purifan, which is a ceiling fan airfilter. They work REALLY well for smoke and odors, but not at all for pet hair really. I have a 4000 square foot home with three Winex, two Coways, one Purifan and one Shark air filter. I used to have a couple of GermGuardians too, but they are kinda loud relative to how little air they actually move. Nothing though is going to beat regularly bathing your pets and regularly vacuuming areas.

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
