Honeywell - InSight HEPA Air Purifier HPA5100 Series

I've only used one. My son bought me a Honeywell HPA 5100B a couple of years ago. It's got a HEPA filter (change every 12th months), a prefilter (3 months), and optional odor and VOC filter (3 months). I use the first two. It's amazing how much visible crud is on the prefilters when they're pulled off. Crud isn't visible on the HEPA filter, but I'm breathing so I guess it's working. I don't have pets or other odor situation, so I don't use that filter.

I have 4 Honeywell insight air purifiers in a 1100 sqft house that still remains dusty at all times. They claim 360sqft cleaning but I hardly noticed any difference. I have to vacuum the filters every couple weeks. At this point I'm thinking of just running a full home air filtration system that literally forces air in and out of rooms through a giant filter. Funny though, doesn't cost all the much more than the 4 Honeywells I bought if I do it myself. Even painting every room with fresh paint and sealing all holes I have this dust issue. Every week everything dusty again. Side note: The Honeywell brand sucks. The replacement filters are literally sheets you have to cut yourself and are so much thinner than the initial filters that come with the main unit. The offbrand filters I buy off amazon are better quality (thicker) and precut. So, while they do collect a ton of dust, the maintenance and replacement is a pain.

Im doing good with Honeywell insight (largest size up to 500 sf). The filters arent cheap to replace but are HEPA & widely available. The only thing I don t like is you cant open it up to clean the vents.

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.

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).

Honeywell HEPA is what I’ve used for decades. Reliable and easy to find their filters.

Honeywell HEPA air purifiers. I have two: one in bedroom and one in the room where I spend most of my time watching TV, etc. Makes a difference for me.
