Alen T500 Air Purifier, Quiet Air Flow for Large Rooms, 500 SqFt, Portable Air Cleaner for Allergens, Dust, Mold, Pet Odors, Bacteria, in Black

I have spent 30 years in the HVAC business. We are focused often on indoor air quality. This is what I do for a living and I have no association with this manufacturer.This filter is shockingly effective at removing odors in my 2200 sq ft house. After an hour in the small room I keep the litter boxes for my 3 cats which had previously had a strong cat urine odor, it smelled 100% neutral. Rooms that are mostly closed during the winter and get musty experienced the same effect. it weighs only a few pounds and is easily moved room to room.After about 3 months I changed the very clogged filter for a carbon one and it's every bit as effective.This filter works for me even better than advertised. I wish I'd discovered it a decade ago.

I bought 2 for a really dusty house. Very happy with the way they’ve worked. Pretty quiet, seem to have reduced the dust problem

I changed residences and had fresh paint and some new flooring installed so was concerned about VOCs, especially in my daughter's room with a synthetic shag rug. The air purifier arrived on time. It was very easy to use. Just needed to put in the filter that came with it. I have it in both my kids' rooms and they use it as a fan. It's much quieter than a regular fan, but will have to check in summer if air flow is strong enough to use just as a fan. I'm not sure how to gauge how effective the filter is. I think the chemical odors did fade away after some use. I don't know how much of that was the purifier and how much of it was simply by passage of time, and I had also installed a carbon filter in my home furnace. Overall I like it and it gives some peace of mind. I would recommend it for closed rooms without good ventilation.

I would like to give them a GREAT. The machine worked great and reduced the coughing from asthma was greatly reduced. I also would like to say the were great on a warrenty issue. After about 6-7 days the machine developed a clicking sound. I contacted the seller on Amazon and they shipped me a new one the next day. I packed up the old one, (amazed at the amount of dust collected in just a week.) and we are doing well with the new one so far. Very pleased!

My lungs are not healthy and I need to breathe clean air. I have had this same unit since 2015 when I first got sick. It is still working like new and it’s on 24/7. We ordered a second one as a back upjust in case the original one finally gives up.

Easy to assemble and quite, having clean air makes you feel comfortable.

I’ve been waking up with headaches for about a year and a half. About the same amount of time I’ve been having roof leaks due to solar panels (don’t do it!). My biggest allergen is mold. It never even occurred to me that the leaks could have caused mold and that’s why I was waking up with headaches. I set it for 8 hours when I go to bed and I wake up headache free! I literally woke up without a headache the very first morning. Also helps with pet dander and odors. The fan isn’t too loud and the display goes dark after you set it so it doesn’t illuminate your room at night. I am very happy with this purchase.

The motor or blower is noisy. I am getting used to the sound. It is much like white noise.
