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 love my Medify air filters!

I love my Medify air purifiers, awesome hepa filters and wide variety of sizes

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

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.

I use Medify purifiers in my classroom and home. https://medifyair.com/pages/why-medify-air

I have seven of them, in various sizes, between my house, classroom, and choir room. I am pleased with them all.

Medify, Coway, Honeywell are all brands I use and trust. And I’ve tried MOST brands. One I DONT recommend is Sans. They’re overpriced pieces of junk.  Just pick one based on sq footage and where you want the airflow (example if you want it to blow out the side, you may feel more of the breeze, or from the top)
