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.

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.

You can get a HEPA filter air purifier (Honeywell makes decent ones) to deal with PLA and TPU, they dont emit the toxic VOCs like ABS, Nylon and PC, but they do still emit fine particles. Having it enclosed like you do is going to prevent a lot of those fine particles from scattering through the room though so its a big help. As a rule I try to not have my printers in the same room I work, but if you must, that HEPA filter will help reduce the fine particles a lot. For the more toxic materials, absolute best bet is to create a negative air pressure environment while venting outside through a window or port. If you cant or want even more reassurance, running a carbon filter does a lot to help. There are specialized air purifiers for VOCs but theyre not cheap. A really good one you can get is from Heygears, called the GreenPrint Purification Unit. Just know it's specifically for VOCs as it doesn't trap particles, it destroys them (so you still want a HEPA for the fine particles). This air purifier doesnt need filters though, it doesnt trap VOCs like a carbon filter which can become saturated and need replacements. It actively breaks down VOCs, so it just runs indefinitely with full efficiency, no need to swap 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.
