Ratings & Reviews for Alen B4-Pure HEPA Air Purifier Filter

Perfection

This filter is good and picks up a lot of dust. I vacuum the filter each week, and it is doing its job.

Filter very good. 45i software and how to set the 45i up needs a lot of work

I am very happy with filter. Not so much with the 45i software and lack of instructions and how to set it up. It is not very user unfriendly and the instructions basically stink. This could be a problem with the hardware but I suspect it is a software problem.

Hepa filter

I think the filter is fine but I would say to the Alen people that you should more prominently display information about lightly vacuuming the filter weekly to extend it's life and efficiency. I heard it on a recording with Alen when I called and was waiting for someone to pick up the phone.

New Filter but still RED

Maybe it's the machine sensor but I put in my new filters--in two machines--and the light remains red after 24 hours.

I love it

The air is much cleaner. So much less dust on the ceiling fan. I love it.

Great Purifier and Worth it!

I have very much noticed a difference in how good it feels to breath now that I have this purifier. I recommend it, it is easy to use and change the filter. I have 2 cats and a dog and 1 filter lasts me all year. I really notice when my roommate cooks and it helps eliminate the smell in my room. I only wish that I could turn the light off through my smartphone but its smart capabilities are great because it’s exactly how you control the purifier manually(other than the light). I highly recommend...

The Best Company Ever!

Alen is seriously the best company around. I've had an air purifier for 18 years and it recently wasn't working that great and a model that they don't make anymore. Alen sent me a brand new Flex purifier and couldn't be happier. Have a 3 year old baby girl and her health is most important. To know she's got clean air and breathing well means everything. Lifetime guarantee is amazing. Professional, classy company. Thank you so much! Felt the difference the first night with air quality!

45i filter

It didn't last very long, much shorter than first one I used.

Though we have a top

Though we have a top of the line furnace & A/C with "all the bells & whistles" we prefer to have another air cleaner in our bedroom. It keeps the air clean & fresh.
