Honeywell - HPA200COM (Allergen Plus Series)

I have 2 Coway AirMega 400 and 2 Honeywell HPA200s covering 1500 sq ft. I have one of the Coways in my bedroom of around 350 sq ft. Normally on 3-4 turning it down to speed 2 at night.

Honeywell makes some good air purifiers that are quiet and have a dimmer function for nighttime. A little more expensive, but reliable. I have an HPA200 and HPA 300 that have been running 24/7 for years.

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.

I have a Honeywell HPA200 and HPA300 that have been running almost nonstop for 7 years. You can find generic brand filters on Amazon that are relatively affordable as well.

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 live in a tall loft with ciment ceilings and it produces a lot of dust. I got a large Honeywell HEPA air purifier and it works very well. The carbon pre-filter can be vacuumed and there is a thick layer of hair and dust every week. The inner filters I vacuum every month and change them once a year.

Just stay away from the Honeywell HPA models. They all develop a burning smell. I've swapped my 2 out a total of 6 times.

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.

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).
