GermGuardian - AC5350B

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/

Coway, GermGarurdian, and Blueair are all top rated. I personally have 2 blueair they work great I have 2 cats and my thanksgiving guests couldn’t smell them or their litterbox at all!

Germ guardian!! Have had one for about 10 years and the newest one about 7 years....they are work horses!

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 bought a couple of Germ Guardian purifiers off of Amazon after Woolsey and they’ve performed well. 

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

I used a germ guardian but it was too loud so I diyed a few air filters for various types of fans and merv 8 filters. Not HEPA, but you can use higher merv ratings for cleaner air. Mine is not the same design as a Corsi-rosenthal box, but that was my original inspiration. DIY filters can filter a lot more CFM and are cheaper to maintain at the cost of elegance and aesthetic you get from commercial hepa filters. I can even turn it on and off remotely with a Kasa smart plug. You don’t have to use the 20x20 box fans that everyone uses, just need an adapter to connect the filter to the fan intake side (I made out of cardboard box)
