We have had our new Alen Breathesmart 45i for just over 2 months now and WE LOVE IT!!!!!
We love the versatility of it (various speeds, various noise levels, light options), and it does a fabulous job.
In addition to this being a solid product, the customer service when we were deciding which model best suited our needs was exceptional. There are a lot of brands out there but for us, we value the quality of the product and the customer service. Alen won on both counts and we couldn't be happier.
