Very happy with this air purifier. Easy to setup and connects via wifi so I can monitor remotely. Ive also programmed it to automatically turn off and on overnight. Highly recommended.

I live in a 2br unit with cats im allergic too. I really love this purchase, its perfect I thought it might be more than i need but it is quiet, efficient, effective and portable. It's very easy to move around and I got rid of my smaller purifier I was using in the kitty area (a few minutes of this does more than 2 hours of the small unit). It looks better and less obtrusive than I thought it would from the pictures I don't have much room to put things and I like this can sit against a wall instead of the middle of the room. My only cons are the display goes off completely when the unit is off or in sleep mode (unlike my small unit) but I guess I should set the app up. Also there is a whirring sound in sleep mode that i don't hear otherwise. I keep it in auto mode at night instead and happy with that. My allergies are much better and during a few recent evenings of poor air quality I was really glad to have this device, its much better than smaller purifiers and I highly recommend it.

We have been looking at various air purifiers for more than a year - reading reviews and ratings (including Choice) on what is available on the market. We like the Samsung machines and in the end it was a toss up between the AX5500K and the AX7500K. Eventually we decided on the AX5500K even though the space we wanted it to cover exceeds what the machine is rated for. The AX7500K was simply too tall and towers over all our furniture. To compensate, we simply move the unit around which is not a problem with it being on wheels and, so far, are happy with our choice.

Not good. Not cold at all

superb a must house appliance that gives fresh airly oxygen.
