Alen T500 Air Purifier - Powerful and Quiet Air Flow for Large Rooms up to 500 SqFt - Portable Air Cleaner for Allergens, Dust, Mold, Pet Odors, Bacteria - Sleek Black Design Review

I was excited to buy two of these two bedroom air purifiers but was so disappointed after they were hooked up. , a strong plastic smell that seemed to increase rather than improve the longer they were used. They should clean the air, not pollute it. I am returning both devices. But they are very quiet, look good and are easy to use. Maybe I have two bad blocks? They generally have good reviews.

I wake up with a headache for a year and a half. For about as long I've had a leaky roof due to solar panels (don't do that!). My biggest allergen is mold. It never occurred to me that the leaks could cause mold, so I woke up with a headache. I set it to 8am when I go to bed and I wake up with no headaches! I literally woke up the first morning with no headache. Also helps with pet dander and odors. The fan is not too loud and the display will be dimmed after installation to keep your room from

It's so quiet I wonder if it even works. My seasonal allergies are on the mend, but was it because of this new air purifier or just the changing seasons? After leaving it on for a few weeks I decided to turn it off for the night. The next morning my nose was blocked and within minutes I remembered why. Needless to say, I turned it back on. So we took him to our musty, moldy beach house. We've tried for years to improve the smell in this place with dehumidifiers and cleaning but never been able…

Never worked. Out of the box the screen would light up and then turn off after a few seconds no matter what I tried. I waited 35 minutes and did not contact anyone. An expensive piece of junk that I genuinely hoped would work. ETA: I spoke to Alen customer service who assured me it was an anomaly so I agreed to a replacement. Arrived Monday and worked until his death today. 48 hours later. The screen lights up. Nothing happens. turns off An absolute waste of time and I am in dire need of a…

I bought this for the master bedroom to complement the large Alen unit I use in the living room/dining room/kitchen and a third Alen unit for the other smaller bedroom. I bought this unit based on its rating for a room size equal to the size of the master bedroom. I don't wake up the device until the moment we go to sleep, so I don't use sleep mode. Works well and is relatively quiet. Since installing it (and other Alen devices) in our home we have seen a significant improvement in air quality…

November 2018 I bought this unit in January 2017 and after being very satisfied the unit is now broken. On the top panel, it will start beeping, go through the timer function, and then turn off by itself. After disconnecting and reconnecting, the device did not respond to any buttons. Now it keeps running, but it beeps regularly. I currently have a device in my child's room and am wondering if it poses a fire hazard. I've really benefited from it, I just didn't expect it to start…

I wrote the most enthusiastic review for the first Alen BreatheSmart Classic I bought 2 years ago for my main living area. It cost a thousand out of pocket to get this block and 3 extra filters. But here in PNW bush fires have become a regular occurrence in the summer and now they bother my asthma so much. In the past few years I've bought 3 less powerful/expensive brands that just didn't fit. So I bit the bullet. And this has more than paid for itself. With regular vacuuming, the pre-filter…
