The experience was easy and the package arrived--a bit slow but there was not rush. No more to say

DEFECTIVE 2x Purchased the I-75 last year and upon arrival, when plugging it in, it was defective. I returned it and cancelled the subscription for the filter. I just received a filter for that device I no longer own. Had to call customer service to get a Return label. Never received it via email so called again. This took 30 mins on the phone .. ABSURD! Thought I'd give them another chance... I took advantage of the BOGO deal and purchased 2 devices... One of them is DEFECTIVE AGAIN! So whatever you purchase full price or discounted, I'm 100% getting a defective item. Who does quality control here? This device has no remote control, and the app sucks. Customer service agents are a hit or miss. I'll pass

Allen air purifiers provide clean, clear air quietly. Love my Alen 350 air purifiers. The air is cleaned of airborne particles and my house has less dust! Vacuuming the prefilter (just under the cover), once a month, is sure proof of how much dust and particulates are in the air. Thank you for providing an air filter to make my home environment healthier!

Excellent product, especially for allergy sufferers I have bought 2 air purifiers over the past 7 years. I am able to control my allergies better with the air purifiers and have reduced how many sinus infections I have had over the years. I love the auto-ship feature with the filters. I know I'll get a new filter on a regular basis and I don't have to worry about ordering it myself.

Best purchase in a very long time! The air purifiers I purchased from Alen are amazing. I can finally breathe again at night. No more making funny noises with my throat or hearing my husband snore. I never would have believed the air purifiers would have made such a big difference in the quality of the air we breathe. We purchased a large unit Breathe Right for the family room and run it every time we open the woodstove to add wood and occasionally during the day. The small tower unit, we run while we sleep. I would recommend these purifiers to anyone who would like to breathe clean, fresh air.
