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.

I used this national allergy website. I got the Dyson and the germ guardian. Honestly I don't think the Dyson is worth the money. https://www.natlallergy.com/

I have 4 cats and one LR3. I found that whenever i start to smell pee it’s because someone has peed somewhere that’s not the box. I have found those 2 spots so I know right where to look. Before I realized this was happening one of the spots the pee got into the hard wood floor. Thankfully I was able to get the smell out with natures miracle. The other spot he would pee was right on the side of the litter box and close to the floor so it would just run under. After the floor scare I put a plastic mat under the box and the pee doesn’t absorb into anything and I think that makes a super noticeable smell. We have gotten the peeing under control thankfully. I’m always paranoid about the smell, like I just notice it clean or not. I put a purifier in the room with the box and I don’t even notice it anymore. I think the purifier is like a germ guardian or something. It works wonders.

The best bang for buck is germ guardian, and the parts are replaceable if something breaks. They sent us a replacement part for one of our units for free, no official warranty or anything. We have 3 of them that have been running for a decade in our house.

I have a germ guardian I bought in 2019 that I use in the room with a litter box and it significantly helps with the smell. I've used it before when my wife smoked up the kitchen trying to reverse sear a stream and it also helped a lot with the smoke. I know it's not one of the more suggested ones here but it's worked really well for me

Germ Guardian. Manual on/off switch that is connected to an alexa switch so I can turn them on and off on a schedule. One in every room. Alexa reminder every three months to buy and replace new filters

I like my WINIX for these larger particles. It has a cleanable pre filter, charcoal filter and the hepa. I vacuum the pre filter weekly to get the cat fur off. I also use an old germ guardian that was my best buddy in a musty old office I worked. It’s still a great unit just louder like a fan so I use it in the bedroom as white noise now It’s worth mentioning a reminder to change the home furnace filter if you have one. I tend to change mine every 1-3 months during high allergen or fire seasons.

I have quite a few allergies, and when we adopted a dog, they became quite serious to the point I needed puffers and was rediagnosed with asthma after 20 years of no issues. I bought a Germ Guardian for the bedroom and I ran it 24/7. It was a lifesaver. I bought one for the main floor and one for the basement and they have really helped. I highly recommend getting one, at the very least for your sleeping area.

Yes! I got one at first and now we have 3! They work so well. Gets rid of weird smells, room not so stale, air noticeably cleaner. I got germ guardian but the others are different brands my Costco had. For filters, I buy the knock off brand ones that fit in my machines and they work fine but significantly cheaper than brand name filters

I got two germ guardian ones and they help with allergies. I also clean my furniture and vacuum consistently so that helps with any allergies. They are very affordable, at least the models I got are $100 and you can find them on Amazon or big box stores
