User’s Reviews: "Air quality is a legitimate thing, and having poor air to breathe makes life less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do.

User’s Reviews: "I have developed seasonal tree allergies and wanted to make sure the air in my home was as filtered and clean as possible. It always runs in the blue, unless I have previously opened the windows, and then it will display green for a few minutes. I did cook steak and onions with the windows closed and it went quickly to RED, and stayed there for a good length of time. I opened the windows and it eventually went to green and then blue. There was still an odor of onions afterwards but it was minimal.

User’s Reviews: "It cleans the air well. I'm currently using it in my 350 sq ft bedroom. I don't have the equipment to test it, but per their website I should be getting at least 4 air changes per hour which is the amount of air exchanges you need for allergies and serious air purification. I've had no smoke smell AT ALL in the bedroom when I run this with the door shut to the rest of the home and it was initially startling to walk from the bedroom into the rest of the home after the first night of using it. This unit has more than exceeded my expectations and meets all the things I was looking for in an air purifier.

User’s Reviews: "I have several of these tall "cool" fans for breeze, sound, and air purifying. (I also have several of the hot/cool shorter fans, also 5 stars for me!). These are dependable and start working to clear the air quickly. This particular one I set up in a basement gym to clear the air and within hours the air quality was so clean and fresh. I pretty much keep them on 24/7. Filters do not seem to need changing very frequently. I even take the shorter hot/cool fans/ heaters on car trips for lake houses and hotel rooms. Love these!

User’s Reviews: "I didn’t realize there was an “auto” mode and it does a great job of adjusting fan strength based on if it thinks the air is good or needs purification. I like that it can self adjust. I’ve been able to tell that it increases the purifying when it detects an increase in smoke. My neighbors are burning in their yards all the time so it’s been very helpful for keeping our home fresh. Not loud at all. In fact, I like white noise and it is very quiet. Smaller than I expected, which is nice, doesn’t take up a big presence in the room.

User’s Reviews: "After almost 4 years of continuing use of my Honeywell Hepa Air Purifiers they are still going strong! I now have 3 of these amazing machines, having replaced all three of my round Honeywell air filters. With regular maintenance and filter changes these air purifiers still do an excellent job of filtering the air in my home. I still have two cats in my home and my asthma has gotten a bit worse with age, but these Honeywell Hepa Air Filters still do an incredible job! The replacement filters are reasonably priced and the machines still maintain a virtually silent operation in the lowest setting. To sum up, 4 years later I am still very pleased with my purchase.

I went through all the lower reviews first and I haven’t had the experience anyone else has had. I personally love the noise, it’s a soothing white noise that mixes well with the rain sounds I listen to at night.
