Very easy to use. Very quiet when operating. The kitchen odor was removed effectively.
One issue is the subscription process. It involves scanning a QR code, fill in a form and wait for a reply to tell me how to subscribe.....the reply never comes, so I cannot subscribe to the filter subscription and get lifetime warranty.
Love this air purifier! We put it on our main floor. We no longer smell cat liter from downstairs. Can also see the colors change when the air quality goes bad to better (for example when we cook) We love it so much we just bought the smaller one for our room! It is also comforting to have an air purifier that works to help with our health especially during this pandemic.
I was perhaps a bit shocked how physically BIG this unit is but it's stylish and I no longer notice it. What I do notice is CLEAN AIR. We have a lot of allergy problems in my household and the Alen BreathSmart 75i seems to be doing an excellent job of removing particles, odors and pet dander from the house. You can actually watch it work. The status light tells you the quality of the air. When somebody goes in or out of the house or something fragrant is cooking, the status typically changes to lower quality and the "auto" setting kicks the fan up higher. If it isn't working fast enough for you, you can manually turn the fan up to high speed and the air is typically clean in minutes. And it's QUIET. We don't even notice it, most of the time.
Hello, Great Unit No complaints. Had the 45i for my room decided to commit to a larger model for the living room, and have already noticed the improvments regarding less dust in my furniture and in general because i have dogs it makes a huge difference.
I am not ready to give five stars. That said I am very impressed with how this filter quickly senses the impurities and goes into to turbo mode to clean air. I lit a very non-scent candle and within 30 seconds the machine sensed it and want to clean the air that I did not sense needed to be cleaned.
