3Pro

I've been happy with this. https://air-fanta.com/products/airfanta-3pro

Agree on the 3 pro! It’s pretty good noise level wise

Glad to see this posted. It's the best one money can buy and it's not even close. I had one of mine die (it was one of the older models) and I was easily able to replace the fans + power supply and now it's working like new. Amazing product and repairable!

The AirFanta 3Pro also uses PC fans so it's quiet. The speed can be adjusted with a dial to a noise level you can tolerate. I have sensory sensitivities and I'm very happy with mine. It's got a high CADR at a low volume level. The 3Pro is $159 and can filter VOCs, but you'd have to buy the carbon filters separately. If you do buy it, be careful about purchasing through Amazon - there is a counterfeit version being sold currently. https://air-fanta.com/products/airfanta-3pro

I love the performance of that Airfanta. It just looks so ugly though

https://www.amazon.com/AirFanta-3Pro-collapsible-portable-suitcase/dp/B0D9D5L15F Basically a corsi-rosenthal that’s mentioned above without your having to get all the supplies yourself. You can pack it in your suitcase when you’re traveling as well. Had this in my hotel room when the wildfires hit LA in January and I was grateful. The owner is very communicative and will answer any questions you have as well. I’ve gone through a lot of air purifiers over the last 4-5 years and this one and the Dyson one are what I still use.

[This air purifier](https://www.amazon.com/AirFanta-3Pro-collapsible-portable-suitcase/dp/B0D9D5L15F) is what I recommend to everyone. It has the highest CADR (clean air delivery rate) per dollar for any option that you don't have to make yourself, as far as I'm aware. It's been a while since I did the research. Something from clean air kits [like this](https://www.cleanairkits.com/products/luggables?variant=47720829583660) is similar and may be easier to fit into your space. But CADR and the filtration medium is all that really matters, and both of those use HEPA filters which filter out viruses very well. They're also much less expensive and much quieter than the option you shared. At that price point I'd recommend getting multiple of either option I shared. Having multiple air purifiers is better than one large one, because you don't need to cycle all the air through the single purifier to get a full air change in the room. I'd recommend an AirFanta 3Pro as that's what I have experience with, and I'd put the at coordinates 3B and F6 on your layout. That more than covers your square footage, but you could do one at 2D (against the wall by the door), one at 6C (foot of the bed) and/or 3A, and one at F6 or G6, to have strong protection against someone in the room. You'd still want to be masked for a few minutes to be safe, but with that I'd be shocked if an air change takes more than a few minutes. They work best if the filter grate is at the height people are exhaling, or if you have a ceiling fan. They won't work as well against a wall because it blocks filter surface area and fights against natural air currents, but if you have enough of them around, that can compensate for the lost square footage and worse angle for intake. Also, if you have central air, you should upgrade your furnace filter to a MERV 13 and replace it every 2-3 months. Being able to turn on the central fan can help clean out the home after visitors, especially if you can't spend a long time airing it out via windows.
