Honeywell - Allergen Plus HEPA Tower (HPA175B)

I don’t know if it’s the best, but it had great reviews at the time. I have a couple Honeywell AllergenPlus units and they are workhorses. They have been around forever and you can buy generic versions of the filters. I have a unit in my bedroom that’s been running nonstop for years.

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!

Honeywell tower is a must!

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, 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 Hepa Air Purifier is amazing all the time especially post fire. It's saved me.

For reasonable VOC removal there are only 4 players I know in the market which offer products which have the minimum 10 pounds of sorbent media: Airpura, Allerair, Austin, IQAir. Wildfires product a huge mix of chemicals - from the vegetation, contents of burned buildings, etc. There is no consumer solution that removes all VOCs. Each type of media is better at some chemicals, not so good or not effective at all with others. For the same reason there is no sensor that I know that will give you the level of all VOCs. These machines and filters tend to be expensive. I just upgraded my Austin units with Immunity Machine filters which cost \~$700 each. We were spared wildfire smoke this season but with AQI numbers breaking 100 I was able to keep my indoor values close to 0. I use Austin and IQAir VOC machines along with Honeywell and Whirlpool HEPA units, 3 filters per room.

Honeywell HEPA. Don't buy an electrostatic/ionizer type "purifier" as it creates O³ (ozone) - which is hazardous (and is also a component of smog).
