Review on 💨 Powerful UFRESH Air Purifier with True H13 HEPA Filter - Ideal for Home, Bedroom & Office up to 550 ft², Auto Mode, Timer & Child Lock - Removes Pet Dander, Dust, Smoke, and Odors by Melanie Trunnell

The UFRESH air purifier with True H13 3-in-1 HEPA filter works well and should provide you with fresh air for many years to come. I really like the auto function. It works faster when the air quality is bad, and slower when the air is good. It is a simple design and easy access to the filter for rear replacement. It works very quietly and the operation is simple and convenient! The display is nice and big and can be seen from several meters away! There is also a child protection system which is nice too. On the other hand, the instructions are terrible. It doesn't tell you what the numbers on the display mean. The numbers fluctuate by themselves. Only at certain intervals do they cause the fan speed to increase. Green is good air quality, blue is normal air quality, and red is poor air quality, which makes sense, but it only seems to change at certain numbers, e.g. B. 31 changes to blue. None of this is explained in the instructions. Overall this is a good fan for a normal sized room.
