Improper fit for BreatheSmart Flex (BH400)

When I installed it I noticed it was sticking out 1/2 inch on my BreatheSmart Flex (BH400). Then I noticed that the device got louder with this new filter. I will come back and order the filter directly from Alain.

Pros
  • Decent performance
Cons
  • Faulty

Emits a strange smell on first use (Silver)

Every replacement filter of this type I have bought from this manufacturer gives off a strange smell during the many months of first use. I even contacted the manufacturer directly and got a replacement from them with the same problem.

Pros
  • Great price
Cons
  • Not as good as it says

worth your money!

If you have an Alen air purifier and need a replacement filter, BUY IT NOW! Choose reliable and trusted brands to purify the air and filter out impurities. Alain stands behind all of their products and their customer service is 5 star. Don't skimp to save a few bucks and add VOCs to the air with cheaper filters.

Pros
  • Dream Come True
Cons
  • Useless Features

Rough smell every other day or is there?

It's hard to give that one star because I love my Alen air purifier, but I decided to get their most expensive odor filter after one of them when I started emitting mold/bad odor from the unit and the room very disappointed. Please note that the device is used in a small bedroom with normal odors. EDIT: I wanted to come back to this review, change my assessment and say I was wrong. The smell I experienced must only have been because it was a brand new filter. Now my room smells great, fresh…

Pros
  • Provides pleasant sensations
Cons
  • There are more interesting options.

BreatheSmart 45i or Flex, True HEPA makes a medium to high pitched box fan sound, it extracts enough dust, dander, fur and anything else floating around in my room 20x18 connected to a kitchen with open views. What I didn't like is that because I also bought replacement filters, I can't get a lifetime warranty on the unit, mostly since I had no idea how well this unit would work and since I have 3 dogs and 3 cats , I wanted to make sure I have enough filters when I need them. So when I had to…

Pros
  • Consistent Test Results
Cons
  • Hard to remember but it was
