    • Works pretty well just don’t drop anything to stop the blades.
Review Image by Baddest latino
So far so good I had it about three weeks and seems to be doing good so far extremely noisy when it’s on number two number one is kind of noisy still not really but you hear it like a humming kind of thing you can sleep to number one setting but then they have the sleep button Where it’s on like really low. And also turns off the light butI just feel that it doesn’t clean the air so well when it’s on that low. I don’t know it could be just me. But overall pretty well. I will update later once I’ve had it for a while. See if it does any improvements with my Parrot because she has allergies. Oh the only thing I wanna nitpick about is if you have a parrot and if anything gets in there with the blade, it’ll get stuck really bad. I had a seed fall in there. It was a Safford seed maybe like 1/4 the size of a sunflower seed and it jammed it up really bad luckily I was able to get the seed out and it was pretty hard but after that came out it works pretty well again. so just make sure that nothing falls on top and jams the blades because it jams up really easy. you think it would just fall through but no it don’t So if you have it in the kitchen and drop a grain of rice on it, it most likely get stuck because that seed I had was the size of a grain of rice lol ... show more

    • Better sleep at night
This is our first time using an air purifier. Our main reason for purchasing was for our allergies. We use this in our bedroom. We both take some sort of allergy medication. Either OTC or prescribed. We would wake up in the middle of the night or wake up in the morning with a stuffy nose. It didn't matter how much I dusted, vacuumed, changed the sheets, etc.. The purifier itself was about the same as pictured. The controls are super easy to understand even without looking at instructions. I like having the option of turning the light on or off, especially during the daylight hours, however I tried it one night with the lights on like a nightlight or something just to see what it would be like. I just leave the light off now. It is pretty bright in a glowy kind of way. Within the first night, we both slept through the night and we can breathe a little better. I have noticed that there is little to no dust around our TV area, that was a spot I was continually having to keep clean and we are not taking OTC allergy medicine as much either. This is probably one of the few purchases we have made over the years that has actually done what it is supposed to do straight out of the box. ... show more

    • Awsome Air Purifier!
My first review indicated I initially smelled something foreign, however I found this to be a normal process of airing out the filter and this faint odor went away! I am impressed with the four speeds to choose from in obtaining air purity not to mention it has an Auto function and timer as well! The Auto button adjusts your air speed according to the room's air quality. Green is Good and Red is... well you guessed it - not good. On the lowest setting I can't even hear this machine! At night, a few hours before retiring, I place the Purifier on a medium speed and at bedtime, I use the Auto button which so far reverts automatically to the low speed as there is a green light on my machine - sensing pure air. All in all, I'm happy with this work horse and very please it is 50% off at the time of my purchase! ... show more

It’s the perfect size and style for my home. I keep it open since I got it, it’s pretty quiet compared to to other purifiers. The filter is easy to replace too. Just overall good household piece.
