MA-25

MedifyAir. They have both wall mounted and free standing options. Filters mail out on a schedule, so I don’t have to keep track- when the filters show up in the mail, I change them. We have four- two MA-25s and a MA-15 for the bedrooms and a MA-35 wall mount for the main living space- and they’ve been great. Quiet, not weird looking, displays that can be turned off, filters that seat snugly in their spots. Fan blades are never dirty. Also to add: I bought the first one almost five years ago and we’ve had zero problems with it. We live in an area prone to wildfire smoke, we have a wood stove that runs almost continuously in the winter, we have a cat and a dog, and no HVAC system to filter the air, so we make these units *work*.

I REALLY appreciate your insight.. finding your info on jaspr is the reason I didn’t make such a bad investment in one of those. My duplex is a closed concept layout.. ceilings are all 7.5ft, living room is 17ft by 11.5ft, two bedrooms are each 10.5ft by 11ft, kitchen is 15ft by 10ft. I currently own a Medify MA-25 and a cheapy arove MK06. Suggestions on what you’d recommend for each room and where I should place the current purifiers I own? I also have a small laundry room and a small bathroom.. do those need air purifiers or will they get cleaned since the doors are open and they’re in close proximity to the other rooms? Thanks so much for all of your help!

I decided to not overthink the green HEPA and I bought to Coway 250 on black Friday sale. It arrived yesterday and I LOVE IT. I know you speak very highly about the Coway 240 that is sold out and I think that will be the next unit I buy when it is back in stock and goes on sale next. I just wanted to thank you so much for all of your help. I was almost going to buy a jaspr because of these false pushes on how great it is.. between it being an extremely expensive unit for what it is, the lower quality filters, and the super expensive filter prices, I would have made an awful decision if I didn’t find all the info you shared on it. I have a Medify which I like but the Coway is even better. I can feel the air quality difference even having it on level 2 because it’s oversized for the room I have it in. That is okay, right? To put it on lower settings if the room is smaller than the capacity? I haven’t done level 1 yet as I assume that would be too weak. I also love that it has a cleanable prefilter and how long the filters last! If you ran it continuously, when would you replace? Thank you again for everything!

Check out Medify Air. They have a bunch of sizes, but I have the MA-25 for my apartment with 1 cat, which works pretty well. They are True HEPA filters, and I think one of the smaller models, you can order an extra pet filter

I have Medify MA-25. High-end HEPA filter. Bought 4 for work during COVID 6 years ago. Bought more for myself. At low and medium speed it is quiet so as not to bother kitty near litter box. Recommend pet version with charcoal for even better odor control. She also likes to sit in front of the much larger and noisier version in my living room. Maybe reminds her of outside wind when she was abandoned.

I wouldn't keep a purifier in the bathroom because of the very high humidity spikes. Laundry room should be okay so long as relative humidity (RH) is below 85%. If it's tiny, you may not really need a purifier there at all. Generally, purifiers in kitchens are not an ideal solution; the best is a vented range hood that exhausts outdoors. If unfeasible, opt for a recirculating range hood instead and *then* consider a purifier. Purifiers aren't designed to handle the oily aerosols from frying, stir-frying, braising, deep frying, searing, grilling, etc. The residue can clog the grills, pre-filters, and mechanical filters. Do you have mold growth in your home? The first step is to run a dehumidifier, as purifiers can't mitigate moisture. They capture airborne mold spores and fragments only. [AHAM 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/) CADR calculations: * Living room: minimum CADRs of 123 CFM * 2 Bedrooms: minimum CADRs of 73 CFM * Kitchen: minimum CADRs of 94 CFM * Laundry: ? However if you have higher mold levels, allergies/sensitivities, or other health conditions, I would choose even higher CADRs. The [Medify Air MA-25](https://medifyair.com/products/medify-ma-25-air-purifier?variant=31541953691715) could go in any room *if* you are running it on the top airflow speed. As for the Aroeve MK06, I don't know - this is a cheap rebadged Amazon brand with no CADRs listed. I'd recommend selling or disposing of the Aroeve. The best quality consumer-grade brand tends to be Coway. For instance, the [Coway Airmega 160 in Dove White](https://cowaymega.com/products/airmega-160?variant=40477296394399) (current sale price of $120.00 each) would be $480 for four units. [Airmega 160 replacement filters](https://cowaymega.com/products/airmega-150-160-filter-set) are $49.99 each, although Coway offers "Buy More & Save More" pricing so costs may be lower. Keep in mind that CADRs apply to the highest airflow speed/setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness.
