I'm very happy with this purifier. As was mentioned in other comments, I question the purifier's blue light which would indicate excellent quality air. Upon startup, after a minute of operation, the light always reverts to blue. I don't think the air quality had been horrible previously, but I'm not running the purifier because I thought that the air was of excellent quality to begin with. Odors Since we don't have smoke in our home or any visible contaminants, odor is really the only result that I can judge for myself. I do not trust the light in this machine that stays on blue constantly. I was not expecting much of a difference in odor after researching purifiers. I had read that charcoal filters don't help much because in many purifiers the air is not in contact with it long enough to make a difference. It took a couple of days, but the difference in odor is amazing. There was initially a very distinct odor in the air. I can't detect any odor any more. While I have no way of proving that other contaminants in the air have been removed, I really have no reason to question it either. Ionization This is just an extra feature of the unit that I will never use. There is question about how well this technology works and whether it causes more problems than it fixes. I cannot say how well this feature works. The best part about the ionizer is that when the purifier starts, the ionizer does not automatically start and I never have to use it. Filters They're a bit more expensive than some of the other models than I had looked at, but they are a higher level of HEPA that will filter the air better. Given the difference in quality, as long as I'm paying for filters to clean the air, I'll take the better ones. Filters are also very easy to install. Air quality indicator Apart from having to buy an ionization system that I didn't want, this is my only other problem with this machine. While running, it ALWAYS shows excellent air quality. There are only 3 levels of contamination indicated so even if I knew the light was working properly, it's only a broad indication about how bad the air might be. Judging by the only criteria available to me, odor, the purifier has made a big difference in our indoor air quality so I'm just ignoring the light. All in all, I'm very happy with this. While I don't trust the air quality indicator and I'd prefer not to have to buy the ionizer, these issues are not sufficient for me to lower the rating from 5 stars. It filters smaller particles than other purifiers on Amazon, the price is not significantly more for this capacity of purifier, and I am so much happier breathing the odor-free air that this purifier produces. I don't have reason to buy this purifier again (life-time warranty if I sign up within 30 days on their website and continue to change the filters as required by the warranty), but I am considering buying other purifiers from the same manufacturer for other, smaller, rooms of our house.

I bought this because I live in southern california & the wildfires have grown far too frequent & intense. It's very effective. Even when the whole neighborhood smells & surrounding areas, this will provide you a little sanctuary, and you'll notice right away when you walk outside that you've been spared in your sequestered space. I'm kind of surprised how much air this thing moves. I live in a decent sized one bedroom apartment. I find if the weather's not warm, I get chilly if I'm in the same room with it. It's really intuitive. I like having it in my kitchen with me because it knows before I do when even something tiny little speck of something catches fire in the oven & is putting out even the tiniest bit of smoke that I can't see or smell. It kicks into high gear & doesn't relent until the air quality is up to its standards. My oven exhaust fan doesn't work, and this air purifier manages to basically do that job, as well. Originally I was moving it into my bedroom with me at night & it was really nice. It really just gives off the perfect white noise. However, I needed to start using a humidifier in my bedroom for a while, and I didn't wanna hurt the purifier, so I keep it out of my bedroom at night for the time being. I wish I could use them simultaneously, but it wouldn't be safe. Pretty easy to move it from place to place although it feels weird to hold it just using the one handle so I always use a hand on the other side too. Haven't bought new filters yet. They are pretty complex with all the layers & probably are expensive, but when you examine it, you can see it's really well constructed. I know there will be more fires & I'm really glad I have this for that, but I also like having it on for just dust & allergens, too. Sometimes just if I move something or step somewhere that doesn't get a lot of traffic, the purifier let's me know that it's much dustier than I can see with my bare eyes. I feel like I have a little protector.

Works very well, very easy to set up as there is no installation besides the filter, the size is on the larger side, but fit well in a room, the fan speed has several settings. There’s one that is quite quiet to one that is on the side., and we use it to help keep our air quality good as we all have a lot of allergies and respiratory illnesses. I recommend this and would buy it again.
