Honeywell PowerPlus HEPA Air Purifier for Home, 968 Ft² Rooms in 1 hour, Reduces Allergens, Dust, Pollen, Smoke, Pet Dander, Odors, Black, HPA3100

I got this because I am a few blocks away from a devastating wildfire so the ash, soot, and dust from 9,000 burned down houses that are from people's lost homes that drift into the homes still standing. So the ashes are both sacred and potentially toxic. I got three of these. I do have to change the filters more often than "normal," but they do keep the air clear. It is not heavy. I recommend the sizes that are easier to move. This is a medium. The noise level is like "white noise." I keep them on almost all the time, and for now, I need to change the pre filter about every two weeks.

Wow this machine is amazing. Does the job. I have radiator heat with little air flow in my flat and this addition keeps it filtered and fresh. I noticed less dust in the room. I will be getting another

Works great. Very quiet.

Seems to help with dust and pollen particles. The fan is fairly quiet on low speed.

I bought the HPA3100 for $75 including tax. I bought this to remove PM2.5 microparticulate, which irritates my airways. The HPA3100 uses a standard-size HEPA filter that is produced by several manufacturers, and is available from many vendors. The HEPA filter should remove PM2.5. The prefilter is quite coarse, and I think it will stop fluff. I think neither the prefilter nor the HEPA filter will remove VOCs or odors, and that OK with me. I don't intend to utilize any of the specialty filters that you can buy separately and install between the prefilter and the HEPA filter. At its highest setting "turbo", the HPA3100 is about as noisy as a kitchen fume hood running at a low-to-medium setting. At its lowest setting, the HPA3100 is about as noisy as fan. The controls on the HPA3100 are simple and intuitive. The auto-off timer that turns of the HPA3100 after 2, 4, or 8 hours is convenient. Accessing the prefilter and HEPA filter is easy.

Great air purifier. I use it in my bedroom which is a medium sized room.

Been running nonstop since I bought it and no problems, only have to change the filter every couple on months, very quiet on its low setting, might still be too loud for some people, comparable to a small fan running. No more stuffy nose whenever I'm in my room

Fit perfectly and work wonderfully.
