A smart investment

I live in an older larger home adjacent to Little League ball diamonds in a mid sized Midwestern city, with strong westerly winds most of the time. Lots of dust! The 75i is working great and the dust inside is mostly diminished but not totally eliminated due to the high winds and sandy ball diamonds. It does a great job but it does tend to run on auto high most of the time. I take that as it is doing the job I purchased it for. My inside air is noticeably better throughout the entire house thanks to the 2 return air ducts on my air handler system circulating the clean air from my Alen. I am pleased. It was a good purchase. I recommend it.

Exceptional Air Purifier

We've had this 4 years now and it has worked flawlessly. The filter levels are easy to get to and self clean, other than the back filter that lasts 16-18 months. Ours runs 24/7 and the filter still lasts that long. It gets rid of cooking odors fast. It purifies the air so it's healthier to breathe through all the seasons. SO happy with my purchase!!

75i breathsmart

We have had our 75i for 5 years. Would never live without one again. We gifted one to a family member and they bought a 2nd one. The filters are amazing. We use the charcoal filter. Although, I feel like the something has changed with the filters, maybe less charcoal? The Breathsmart helps keep our house from smelling like all the food we cook.
