Honeywell we use the big 500 sq foot one for main floor and the smaller 200 sq ft one for the bedroom leave them on low change filters every 4/6 months
We have a 2 story house and on the main floor we’ve been through 3 high priced super duper fancy ones since 2020. They stop running, start making noise, we can’t find filters, it’s always something. Upstairs we have an inexpensive old fashioned black box (Allergen Plus) from Honeywell that just won’t quit. Get the ugly one from Honeywell.
Sufferer of lots of allergies, including dust mites here! My allergy dr recommended a few things: mission allergy brand pillow encasements (this brand only- apparently other ones don’t work as well) https://www.missionallergy.com/product/barrier-2-pillow-encasings; wash your sheets, blankets, mattress covers in HOT water; use an air purifier. We’ve used Honeywell Allergen Plus HEPA air purifier for years now and it helps a ton. It’s not the quietest, but it’s a nice white noise while we all sleep.
I love the ugly-ass Honeywell tower one i have. You can get washable filters too, which is a nice money saver. It's relatively quiet and powerful. Everyone should make at least one Corsi-Rosenthal box though because they are super effective!
I have a huge Honeywell tower that I loved for my old studio apartment, but now that I’m in a large house I honestly think corsi-Rosenthal is the best bang for your buck. They’re incredibly effective, cheap, good for large spaces, and customizable.
Yes. I have Honeywell HEPA units in multiple houses. 24/7.
Yes, an air purifier helps. The best brand is Honeywell with a HEPA filter. Second is Bionaire with True HEPA filter (purple one), third is Bionaire with the blue filter. Levoit kind of sucks. Don't waste your money on the Pure Enrichment Personal Air Purifier.
Honeywell. Their HEPA air purifiers routinely test out as the most effective and they make units made for spaces that large (I have one, it's such a relief during wildfire season). They aren't the quietist or the prettiest, but they don't need to be because they work. If you'll allow me on my soap box just a sec, please don't spend your money on popular "technologies" like ozone, static electricity, magnetized, etc. They don't work. What works is certified HEPA filters, H13 or H14.
