DREVAL D-4850 8 Stage Air Purifier Humidifier- Combo Air Cleaner, True HEPA Filter, for Home, Kitchen, Bedroom, Large Room Capacity, Ozone Free, Super Quiet

update - almost a year later. No complaints Great unit! It’s exactly what I was looking for! Dreval air purifier and humidifier is a powerful enough to clean air in a large living room. At the same time it works very quietly, almost no sound coming out. I use automatic function so it works in its best capacity. It humidifies, sterilize, ionize. Very convenient. I like the stylish look of the unit. Blends very well in my interior. I highly recommend Dreval purifier and humidifier.

We are very happy with the machine, feel the difference in air quality immediately. Will definitely recommend to my friends for the upcoming winter season in NY (central heating is a nightmare)!

I've now had this for almost 1.5 years and it is still working great. Air purifier is still working and enjoy seeing the different light colors change for when it encounters dirty air (for example right after cooking). This is a great combo product as it is also a air humidifier and so we fill up the water tank daily for the cold dry winter north east months. The sleep function works great at night, one press and the the lights turn off and the machine goes to its lowest level so you no longer hear it. Great product and still going strong.

Hard to figure out what the numbers mean on the machine. May be air purification, but there is nothing in the booklet to indicate what they mean.

After more than one year used, not good enough for the price! Still lots of dust around the window! As well, customer line doesn’t work, no response for the email!!!
