Medify Air - MA-15

I bought a 2 pack of Medify MA-15 for \~$150 USD on amazon and have been using them for a few years now. You can get aftermarket Hepa H13 filters for it with all sorts of improvements that can target things better than the filter it comes with like pollution. They are also very inexpensive relative to other air purifier filters. Each one is good for just under 600 sq/ft and they are whisper quiet. At the lowest setting you don't even know it's on. It only really makes noise on its highest setting.

That's awesome they did that. The air purifiers need to be appropriately sized for the room. I have one in my office that works well (Medify 15), but I do not use one in the classroom. Our facilities management was zero interested in adding any air purifiers to classrooms even right after COVID. I also had my own Aranet4 CO2 meter, but I dropped it and it broke. Still might consider getting another one or a different brand. Our windows do not open. Luckily I am often in a classroom where no one teaches before me so the room does get to air out. I am super lenient with students being out sick.

I can second this suggestion- it's a great model!! I'm not confident the air is going to mix down a very long hall to the kitchen by itself (regardless of the cadr of the purifier). If you had the stovetop exhaust fan on pulling air through, or just a regular fan somewhere on low, that might get air moving in from the hall, into the kitchen, so the purifier could pull it through.  Re: bathroom- it's my understanding humidity isn't good for HEPA filters and that there's a usage range, but I've operated small ones on bathroom countertops okay. I don't live in a humid area, and my bathroom does not get super steamy. I used the smaller levoit, and a small medify model. (Sorry don't recall model #s).

I have two dogs in a townhome and have 3 air purifiers. Absolutely love them. No dog smell. I have one Medify and two Levoit. Just make sure you get one that can actually clean the size of the space it will be in. The downside is buying the filters, but I find it worth the cost, and you can find cheaper, off-brand filters on Amazon.

medify needs more love. those medical grade H13 filters are legit

I bought 5 Vital (100 + 200) devices and 1 Core. The vitals barely reduced PM when I used them. I switched to Coway and Medify and had much better results.

I've been using Medify Air for 5+ years and they've held up well. They work well, especially during wildfire season. I also run them when guests are present to reduce the spread of airborne germs for an immune compromised household member.

We use medify air purifiers

Honeywell, Levoit, Medify, Coway

It depends on the size of your rooms, and how much noise matters to you. They will all be great for pet hair, dust, and have models at about $250 to $300, for your total $600 budget for 2 units -- but you need to get models that appropriately cover the square footage in each room. Typically models will advertise the square footage they cover on the highest setting -- which is the loudest. You want to be able to run it on lower settings most of the time, so check the square footage they cover on lower settings, and/or "overbuy" for your space. Also check the pricing for a unit's replacement filters -- that's an important cost consideration. Finally, if you can swing it, I also recommend units with activated carbon / VOC filters for smells, when you have pets :)

tbh they're all basically the same. just get whatever's on sale at costco that has a hepa filter. i got some random medify one for $150 and it works fine. people overthink this stuff way too much lol
