Love the Air Purifier, it works well and it is so quiet. Easy to move from one room to the next. It quickly removes odors. Love the sleek design it works well in every room in my house without being intrusive. Would definitely buy another in the future. Highly recommend!
We are really pleased with this purchase of the 45i driftwood cover. The filter method works similar to others with 2 stages (initial carbon filter plus the HEPA filter). The controls are easy to understand and offer a lot of flexibility in how the system works. What's really wonderful is the way this looks. It's beautiful for a functional air filter - it's probably the nicest looking HEPA air filters on the market. We keep it in the bathroom with the kitty litter and it really helps keep the smell down.
I am very sensitive to noise so most air cooling equipment keeps me awake even when set on the lowest speed. The "pink noise" of the 45i does not keep me awake. It actually helps me sleep more soundly. The sound is very quiet. The color indicators reflect the particulate matter in the air...as evidenced when I burnt my dinner several rooms away and the 45i reflected that fact with its purple circle. I purchased a colored front plate to match my bedroom and was very pleased to see the front plate attaches with magnets. Just pull off the front plate, no sweat, no mess, and the new one attaches with a magnetic pull. Couldn't be easier. I have the FL-40 Silver Carbon filter.
I can really tell the difference in the air quality with the Alen air purifier. It has helped me breathe better with my allergies and asthma. My family likes the modern look of the unit. I found it easy to operate straight out of the box.
I have only had the unit for several weeks, but it seems to be doing its job well. I opted for the odor remover filter add on because of a dog smell in my home. In the room that I have put the unit, the smell is all but gone. I am also pleased by how quiet the unit seems to be. We will see how the unit continues to work over the coming months and I may purchase a 2nd one for the bedroom.
Have been using our new 45i on the auto setting for about a week now,there is a noticeable difference in indoor air quality and reduction of dust and odors. The air quality sensor is ve
