No instructions installing expensive filters For $70 for replacement filters , it's a disgrace that there are no proper installation instructions.

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

ordercatcher The machine is to loud.I can not tell if it is helping.I trust it is.

Great product, customer service needs some work After researching for months, I decided to order two Alen air cleaners in early November. I called to talk to a customer service rep because I had a special request concerning shipping. I wanted to get the filters before Thanksgiving but was unsure of when to order them because I was going to be out of town and I didn't want to miss the delivery. The rep told me I could go ahead and order and he would talk to shipping and delay the shipping of my order. Instead, my order shipped right away while I was out of town. Everything turned out fine, as a friend watching the house brought the filters in before they were stolen. The point is, I didn't need to spend 15 minutes on the phone with the rep who was not able to take of the delayed shipment as promised. The other thing I found disappointing was finding out they had a "Black Friday" sale. I could have saved $150 on my two A350s. Here's how Alen's rep could have guaranteed they'd get a 5-star review: when I call tell me I should just wait another 2 weeks and order after Thanksgiving to save money and get the shipment delivered after my out of town trip. As for the filters, they are fine. I live in the desert with lots of dust and I have dogs. The amount of dust in the house is visibly reduced and my home doesn't smell like dog. The low settings are very quiet. The highest setting is a bit noisy but that is to be expected if you expect it to move that much air around. It actually helps me at night because I sleep better with white noise. Though I don't have bad allergies I am less stuffed up than I was before I bought these air cleaners. I would recommend this company and their product to anyone, just don't expect any personalized customer service if you call instead of ordering online.

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
