I'm using the BreatheSmart 75i in my shop. Recommended by Consumer Reports. Love all the options/buttons: timer, ionizer, filter life, automatic option & lock. It seems to work beautifully. Is super quiet. And is rated fabulously. I, literally & figuratively, am breathing easier with this air purifier on & in my life.
My breathing has bee so much better since I received the unit.. My allergies are much better.. Not completely gone but so much more manageable. I'm so glad I found this product!
runs very well and as expected. Make sure you select the filter you desire at time of initial purchase. I would have preferred the activated charcoal/pet odor filter. So far I am quite happy with the purchase.
This we is our 4th Alen product. We bought 1 for my office & 3 for our house put in different rooms. We like the smart technology, quietness of the product, & customer service of this company.
