I bought two alen purifier in 2015 they have ben running 24 hours aday 7 days a week. Not a single problem..nothing lasts 7 years in this day and age. What a unbelievable product. Also I called alen to change my auto delivery and I actually got to talk to a live person with out 45 minutes of crappy music and a recording about how important my call is. Great product great staff. You won me over. Great job thank you
It was easy to set up, runs quietly, and as soon as I have dusted, I will see how efficiently it decreases the amount of particles in the air. Service has been exceptional!
we use it on auto mode, and it seems to operate accurately. we have it in our living room close to the kitchen and pet room, and there has been a noticeable decrease in odor. whenever it detects significant air particle in the vicinity, it also motivates me to clean even more vigorously! the space is very expansive so I am very happy with its ability to purify the air of such a large open space. I have noticed less sneezing.
Easy, clear cut setup. Product look great and is very quiet at the lowest speed. Not sure how it actually measures air particles to determine speed but am sure customer service/tech service will be helpful as they were in answering all my questions prior to purchase.
It just sits there and works. Hopefully we will have a much more mild fire season in Oregon but it was a driving factor in the purchase in addition to dealing with the crazy amount of pollen we have in the valley. The auto feature is nice and noticed it ramp up when outer doors are open or we cook. Got the subscription to get the extended warranty so this bad boy can run 24/7. Super simple instructions and video helps with the little amount of cleaning and service you need to perform on the unit.
