In contrast to other air purifiers, which pull in dirty air through the front panel, this air purifier has a distinctive design in which the contaminated air is drawn in through the air intake grilles present on the sides and the bottom.

But that is not the case with the Alen BreatheSmart Classic; their advanced ionization system doesn’t generate dangerous ozone.

At last, the pollutant-free purified air is sent out through the top. A effective fan makes sure that the pure air that is provided through the top grill hits the ceiling and then spreads uniformly across your room.

Smart packaging: The packaging of the Alen BreatheSmart air purifier is quite good and smart. It’s very simple to unpack and set it up. The boxes are intuitive and easy. The Alen

BreatheSmart air purifier should have an industrial design award, one customer says. Once you open the box, you’ll wonder why everyone else’s packaging has to be so bad/so difficult to open. It’s elderly friendly as well. If you’re old and have problem lifting heavy things, you’ll be happy with the Alen BreatheSmart air purifier packaging. They set it up very smartly to minimize the strain of pulling the device out of the box.

Good customer service: Among the list of users had a problem with a sensor light. He went to the Alen website and submitted a ticket for help. He got an immediate reply the following morning with a suggestion. The suggestion did not work, and they gave him another suggestion, which needless to say, did not work, as there was a faulty sensor. Each backwards and forwards was with the same person who immediately replied.

He did not have to re-explain his problem each time he called the help line. After the suggested fixes did not work, they (the manufacturers) rushed to send him out a replacement. They asked him to return the faulty unit in the box the new one would come in, which unlike most companies, they did not require him to send in the defective device. It could not have been any easier, he says.

Loud at times, but not disturbing: The only downfall with the Alen BreatheSmart air purifier is that it could be a little LOUD at times. The sound level is not it is just a blowing sound. Having said that, you do need to switch up the TV a few notches up when watching a movie or something.

Takes up bit of space: It takes up quite a bit of space compared with other best air purifiers, but that is not a fair comparison, as this model was not advertised as a “space-saving” tower model. Just keep in mind that you’ll need a space that is at least 1 foot out from the wall and almost 2 feet wide.

The breathing space for this device is required to grab the air well – the fresh air is brown out from the top.

Customer Reviews

Some time ago I decided to invest in an air quality meter by Awair to measure air quality levels (chemical / c02 / dust / etc). I did this as I recently moved to a well-sealed modern home — and as such I wanted to keep an eye on internal air as we close up tight during winter. Unsurprisingly – our dust levels steadily raised this winter as external and internal air was cycled less. This is despite having a Hepa system on the central air.

Since I like clean air, I had two choices: upgrade my central air for thousands of dollars, and hope that it works… or target particular rooms via in-room filters (like this one from Alen) and save $$. Well, the results from my air quality meter prove I made the right choice. In only an hour after turning it on, I cut the levels in 1/3 down to nearly the same as exterior air.

My nose can certainly tell the difference. Inside air now smells like outside air. My home is nearly 2,700 square feet — open floor plan with very tall 15-20′ catherdral ceilings. This models potential to cycle and clean the air (with help from my central air as well) brought my interior particulate levels down.

Another review
I waited 6 months before posting this review to give you a truly accurate idea of performance. This bad boy is totally awesome. Between me and my cat, I do not know who suffers from worse allergies and needed to find some relief.

After doing a ton of reports, I settled on the BreatheSmart (but we just call it Allen) and it is made a night and day difference in our air quality. The air is clean and free of particulate and so pleasant that when you throw in a little Netflix and Chill, I never want to go anywhere any more; it is so nice at home! Sound-gives a pleasant white sound hum that I find neither too loud or soft.

With regards to Performance the Alen Alen BreatheSmart Classic works very good. The device cleans my 1200 square ft apartment (no walls, just one big loft) with no problem. The Alen BreatheSmart Customizable Air Purifier no small thing but even at its size, the design of the device makes it easy to tuck against a wall and it does not feel obtrusive.

The filters are not cheap but if your buying a purifier of this scale then you understand its need for a high performance filter. I have mine for 6 months and am just now able to discern a difference in air quality and ready to purchase the new filter.

Alen Classic Air Purifier FAQ

Q: is maintenance easy to you change filters ets.
A: I have only had to change the filter once so far, and it’s easy. You just get rid of the front cover, pull the old one out (have a trash bag handy because ours was gross and covered in dust). Then pop in the new one.

Q: How noisy is this machine – it is for the master bedroom. Thank you
A: On it is lowest fan setting it’s very silent. It has four speeds. We leave it on “automatic” in our living room and for the most part only the highest of the four speeds is quite noticeable. We also purchased an Alen Paralda for our bedroom suite and leave that unit on the second lowest speed and it doesn’t bother us at night.

Both models have clearly lowered dust in the air and mold issues are almost entirely eliminated. This is the first winter in years that I have not had to use a decongestant so I am pleased with the purchases.
