The 45i true hepa is doing the job. It looks great and has actually helped with my allergies. It is quiet and you can turn the display lights off at bedtime. I highly recommend this product. I want another bigger one for my living room when possible.

Only had the 45i for a week now and to soon t render a honest review. Need more time and honestly how would one be able to tell a difference in air quality? I have to except your specs and the purifier does what Alen says it does which is everything we want it to do in this COVID time we live in. Thanks for listening to me. Louis

I think the decision to buy this air purifier was a good one. It makes a noticeable difference to how the air feels and smells. I was disappointed, however, when I ordered a different cover for the machine than it came with, there is a good selection of different covers you can choose from. I picked one out that would match the decor in the room. But they sent a cover that does not fit with my machine, so I need to return it for the right size. I will submit another review to comment on the service to customers, but if the product warranty is so good, I believe customer service will be pretty good, too. Just a mistake, it happens.

Very happy with our Alen BreatheSmart. Very easy to set up and use. We're using the odor filter and find it to work very well. We already ordered our second unit based on our experience. Since a paper manual does not come with the purifier, I would recommend, if purchased, to go to the Alen website and print the owner's manual as it has useful information.

I am so excited about this Air Purifier. Within two hours of operation, It went from red to green. I now wait to see it turn to anything but green or blue, just to see how fast it cleans the air. And It is so quiet. that there are times that I don't realize that it's on. I will purchase the lifetime filters for the lifetime warranty. We are going to order another one for the upper level.
