Every home should have an Alen Air Purifier
on November 25, 2020
Posted by: Ada R.
I am so happy with my Alen Air Purifier, I live in an old building and keeping dust is a daily chore but this filter has reduced the amount of dust and I keep it on most of the time. It stays on at night and my sleep has gotten so much better because I don't wake up with a congested nose in the middle of the night.

My third Alen purifier filter.

My third Alen purifier filter. Perfect for the intended space. Surprisingly, I find it much quieter then my first two. Never had any issues with any of the Alen purifier filters. Keep up the good work and quality.

Seemed to make a difference after 24 to 36 hr. Air smells pure (strange, but true)
Great machine.

The Most Cost Effective Choice of Air Cleaners
on November 30, 2020
Posted by: John G.
I could write a book on my allergy symptoms but no one would buy it. The cost and misery for 67 years of allergy symptoms with resulting infections would buy a new house. With my new BreatheSmart Flex, I hope to have a pollen season that will be worth writing about.
Cedar and Oak Pollen seasons are coming up soon here in South Texas along with the sinus pain, itchy eyes and runny nose along with it. Also, Covid-9 requires me to stay healthy and protect my breathing as best I can so here we go.
I sold HVAC systems for many years and I watched the available air cleaners on the market. I wanted a design like the BreathSmart that I purchased and I did not want to pay the extra money for the 1 percent improved efficiency you get with electronics. Also, I did not like the ion air cleaner I used for two years. It did not handle the space advertised.

I deliberately purchased an oversized BreathSmart air cleaner from you and I may get another one for the bedroom. Now that I am retired I plan to stay inside when the high pollen count blows in.

My purchase experience was flawless and so was the delivery.

We moved into a new
on December 1, 2020
Posted by: Corinne R.
We moved into a new to us house and the mold was very noticeable in the air. After 1day with the air purifiers there was a major difference in the air quality. A week later the smell was completely gone. Very easy to use! Set up out of the box was very simple, just unwrap the filter and the lid sets on. No tools needed. The push button system was very easy to figure out. I highly recommend this product.

Love the product; hate the ubiquitous advertisements
on December 5, 2020
Posted by: James B.
We bought a FLEX for our relatively small bedroom (about 200 square feet) and it works extremely well. We run it at high speed when we're not in the room and at a low speed when sleeping. The unit is rather loud at high speed, but the sound is diffuse and not at all unpleasant. We vacuum the pre-filter every week or two. We do not like the immediate appearance of Alen ads on every website we visit, but this seems to be part of the price for anything you buy these days.

Love it!
on October 15, 2020
Posted by: Kimberly N.
I love my filter. It cleans my air quickly and helps with my dust allergies. I love that I can keep it quiet when I want it to be and also turn it up for white noise. I like white noise when I sleep so I put it on the highest setting. I also love that I can turn off the lights of the machine so easily at night! It’s a great purifier. I already knew I would like it because my sister has one and I love hers. Now I’m saving for the biggest one to put downstairs in my living room.
