good price, great quality, dependable product
Love this air purifier, its light weight, super portable, and works really well for average sized bedrooms, its quiet and has multiple speeds which is nice, and I can usually tell when it is on and working good because my allergies are in check. at the price they have it listed for its worth every single penny, just wouldnt get this one for the larger rooms like master bedrooms or big living rooms etc. also if you have pets at home keep them out of reach, I had mine on a smaller table in the bedroom and noticed that my dog would accidentally turn it off by just hovering his head over it and touching it the buttons seem to be ultra sensitive to touch but not a bad thing at all

Good addition to any room for both aesthetic and health.
Two days into using this filter, there’s been a noticeable difference in bedroom smell and air quality. Four weeks after receiving it, I can see everything it’s caught. It’s also a tad more grey. The option to change light colors or turn off the light adds a nice aesthetic touch. While the lighting itself isn’t that bright, it’s nice to turn off for when I sleep and not want be kept up by the alternating colors. The first two fan speeds are super quiet. High speed sounds like it skips “high” and goes to extra high. Good for anyone who needs a kind of white noise to help them sleep at night. $30-$50 for this is a nice steal considering how fast it cleaned the air in my room. As for “size,” it was somewhat bigger than I expected, hence the Switch sitting next to it for a visual size comparison. I’m taking this with me to a friend’s who has two cats and a dog to help gauge how this affects my allergies soon. I’ll update when that time comes. **post visit, I think getting a yellow or green filter for this would be better. **upon replacing the packaged in filter, Green/Yellow filters are a must. Using either in an environment with pets will definitely catch whatever fur might be lying around. My replacement green filter caught a considerable amount of fur and dust after just one night elsewhere. ALMOST FOUR MONTHS AFTER PURCHASE - bought this 8/30/2024. The red light replacement indicator came on after almost four months of near continuous running (12/16/2024). The filter has definitely worked well and captured lots of dust fuzz. In my case, I’d say the filter life for a small bedroom along lasts a good long while (although this could be dependent on living situation and type of filter). A 2-pack isn’t too pricey at all and can last 3.5-7 months if I had to take a wild guess after replacing the packed in filter. Maybe two 2 pk purchases a year at most. As far as I’m concerned, this is a worthwhile purchase. Would recommend.

Love it, will buy again.
I just got it and is almost inmediate the change in the air quality. I live in a place with sealed windows (because of severe snow) and the way humidity and dust accumulates is insane, air quality was killing my lungs and I was worried for my newborn. Its been only hours, and I must say, it feels so relieving, is not like being outside, but almost. I would definitely buy some more. On other topicks, size is ok for me (not too big, or too small); On low and medium make almost no sound... and high can be a good white noise for my baby to sleep. Its very light weight, its has helped with my allergies very good, so I believe its efficient and great quality for its price.

Does the job, Maybe?
Not terrible. A little loud. Can't tell if it's actually doing the trick because I don't have a whole lot of odors in my room. It's a little difficult to find replacement filters, so at the moment it's out of commission. It's easy enough to use; I keep it running 24/7, I just wish it was easier to find replacement filters that are the correct size.

Works really good
Worked really well in my room it definitely felt much cleaner and was really easy to set up. I usually get allergies pretty bad but honestly it has helped me out. It fits perfectly on my desk and it’s been working good for a good while now. I would definitely buy again for another room or the living room

Great purifier for an even better price
Bought this for my son’s room who has bad allergies. I couldn’t find the one I had when he was a baby but didn’t want to spend a lot of money on a new one. This one works great. You can change the fan speed I also like the lights it has and how you can change it.

Quality Air Purifier
Easy set up. Seems like quality construction. Runs pretty quiet on the middle to lower settings. I run an auxiliary fan in my bedroom so the noise isnt an issue. In fact i'd welcome it if it was loud, which it isnt. I run an aux fan as that helps circulate the air and speeds up the air clean up for the px500 to do. So far the air feels less musty within an hour or two in a 12x10 foot master bedroom with attached bathroom. Ive noticed that within a week the dust accumulation on surfaces is much, much less than pre-air filter.

It’s made a huge difference in my skin and my sleep, my room feels lighter and the air isn’t as thick.

ÓTIMO
Chegou muito antes do previsto. O estou testando agora. Como precisa manter tudo fechado, comecei a sentir um pouco de calor e liguei um ventilador mas não direto no purificador. Por enquanto, estou muito satisfeito com a compra. O ar está bem respirável e fresquinho.

Works well, but design is flawed.
Works well. Put it in our room when my dh had the flu and I didn't get sick at all. Only issue is the bottom doesn't stay on properly. Every time I move it the bottom falls out and the filter with it. It's supposed to lock in place but it comes off so easily. Ill have to secure with duct tape. Other than that, Works great.
