Purchasing the Alen 45i was easy and fast. It was delivered within three days. 

When I received my purifiers, I noticed how easy it was to unpack and set up. With a custom box to protect the contents (And super easy to open) and East to follow directions, Alen guides you through the process every step of the way. 

I purchased 2 units to use in my (large) classroom this year but am using them at home until I go back to teaching. I noticed a significant benefit within the first 24 hours. The unit cycles automatically pending air quality. I noticed the smells of cooking don’t last in the house any longer and I breathe easier - less allergy. 

The units are quiet even in high. They’re quieter than a fan running. If it weren’t for the light on top (which you can turn off) I wouldn’t even notice they were there. 

I would recommend Alen. I feel confident in the product and worship.
