BF15A-Pure True HEPA Filter Compatible with Alen A350 / A375 Air Purifiers by LifeSupplyUSA (2-Pack)

Overpriced. Totally worth it. Quality and available.

Unreasonable price for 6m filter

I don't know why there are bad reveiws. I just ordered 2 of these regardless of the bad reveiws. They looked, felt, and weighed exactly like the allen filters. they fit perfect...And they came with the velcro prefilter as well. Allen has really jacked up their price on theses. Do your self a favor and get these. I am orderinging 2 more at this price of $36. The Allens are $69 now.

In my opinion this filter is low quality. The outer frame of the filter broke just from handling the filter. And the filter is not a tight fit in my Alen A350 air purifier. What’s the point of having a hepa filter if air can leak around the outer edges?

Hello. This fit my Alen 350 perfectly. I have purchased this multiple times over the years.. I take the old one out, clean the unit and inserted new filter. The fit is perfect... I do not understand the fit issues with other purchasers. This fit perfectly into the Alen 350.

My clean air machine is quite old, and I have had it several years. The price of their filters has not gone down. The generic filters work for less money, and I am happy

This is my second time buying this filter for an old Alen A350. The first filter had no issues. The second filter is slightly shorter in height compared to the OEM filter and does not contact the upper switch that is depressed when you place a filter in the unit. I almost threw away my A350 until I tested the old filter and the A350 turned back on. I added enough electrical tape on the new filter to depress the switch. Not buying this filter again.

A good value
