    This air purifier works well. The controls are intuitive, it's relatively quiet, and the filter is easily replaced. Our first filter lasted about 8 months and we replaced it with one from a 3rd party - so far so good after 3 months.

    Bought 2 of these and can definitely tell. The difference in air quality. The air feels fresh. Shark filters are on the pricy side though.

    This has been a good air purifier so far. The size fits nicely against a wall and the unit runs fairly quiet. I do sometimes question the reading I'm getting on the screen however I think my humidifier may be confusing the sensors.

    Absolutely LOVE this thing. My house just feels better and cleaner with it being in here. I don't have a fan in my kitchen, so when I cook I depend on this thing to filter the smells and it gets the job done. Dust has been way more minimal, too. I hate the sound of fans running and this thing is so QUIET. I keep it on automatic setting, so when it kicks on higher I can obviously hear it, but it doesn't last long and kicks down on its own. I love having a remote to control it from my couch, too. If you are like I was and are relying on reviews for sound, this is for you. Buy it.

    This air purifier is very quiet at low speeds and kicks in as soon as it senses odors. I keep it in my kitchen, and it keeps odors to a minimum while cooking and clears the smell quickly.

    Looks to be a good air purifier with a lot of features, and adding convenience with a remote control. It also looks very nice that would add a great decoration to your room.

    I got this on sale. We put it in our bedroom first. Our bedroom is quite big. I was a little skeptical because it immediately said 94 or 95%. When we have dogs and cats and vape. But when I blew Vape smoke towards it it automatically went down. I do vacuum and clean a lot. But I feel is on going to give it a little more time before I am totally sold on it. If I had paid full price I'm not sure I would think it was worth it. I brought it downstairs today it again is reading good levels. Which I just find odd. The real test will be when my brother-in-law Cooks fish which is what I really wanted it for. I will update when he does that if it actually helps. If it does I plan on buying another one.

    great air purifier. my cats jump on it and like to turn it on and off so if you have a couple furry gremlins running around that'll happen. If your brother does 8 b0ngs a day this thing will have a heart attack each time.
