AlenAir Filter B7-Pure Replacement H13 True HEPA FIlter for BreatheSmart 75i Air Purifier - Captures Allergens, Dust, & Mold (1 Filter)

This filter fits in my air purifier perfectly. I am obsessed with clean air. It lasts a long time. (Around 1 x a year. While quite a hefty price for a filter, consider that you are buying enough for a whole year. I’ll order again and again.

My alen air filter unit is 3 years old now. I have two units. The product has been great. I can feel the difference in air quality. The filters themselves are high quality and easy to replace.

My Alen Breathesmart 75i came with the “True Hepa Pure” allergen filter for dust, pollen and mold. I’ve replaced the filter twice and both times upgraded to the “True Hepa Fresh” filter that also addresses smoke, kitchen odors and VOCs (volatile organic compounds). I notice a difference with respect to kitchen smoke and odors, such as cooked fish. And wildfires have become a yearly occurrence in my area, so I feel it’s healthier to filter out as much smoke as possible as I can smell it inside at times.The 75i with the True Hepa Fresh filter makes a huge difference in my indoor air quality. The filters generally last about 12-15 months, though I went ahead and changed mine a few months early given all the fires this year. The filter already has the prefilter in it (so don’t buy one). While I don’t enjoy spending money on filters, I think it’s totally worth the cost as the allergens and smoke are health issues and I’m aware of a noticeable difference in air quality and how I feel. Definitely recommend. 5 stars.

Alen makes a great product, if not an inexpensive one. Has done a fine job the year I've had it.

My home as I have allergies.

fits perfectly

I bought my Alen 75i last summer, and the filter it came with lasted until early this summer. I live in an area with wildfires/lots of smoke, dust and I have a woodstove which also causes some indoor smoke - last year was intensely smoky with the wildfires. This replacement filter, which I installed in June of this year, lasted all of three months before reading 'orange' on the unit, meaning it will need to be replaced soon. A filter that costs $129 should last a year, not 3-5 months - esp compared to the filter that came with the unit. While I'm very pleased with the unit and the air quality it provides, I'm now wondering whether other units would be as effective at a better price.

It is perfect in every way.
