Works extremely well and very effectively-you can smell the difference after a short while. I purchased an additional 2 X3s for family and they absolutely love them as well. I purchased them initially for the washable filter, but even without that awesome feature, it's an absolutely amazing air purifier. I can't recommend them highly enough.

So far it is amazing I haven’t had it very long. Time will tell.

This is my second purchase with you yet my first ask for a review. I have had mineFor about 10 months I've had to clean it twice, We'll have to clean it a third time. The second one I bought for a friend. I will be buying a third for my daughter. The cleaning instructions could be better and I have no way to get a warranty for these items. They work very well thank you.

[This review was collected as part of a promotion.] I’m a happy customer of AirDog. I have one of their larger units in my garage and then my favorite for rooms is the AirDog3. What I like most is how quiet it is (while still doing a thorough job of cleaning the air). The AQI reading is also a nice feature as well as the 4 air flow settings. Read the cleaning instructions carefully is my best advice, this is different from other air purifiers. Once you learn the instructions, it’s easy.

I have had my Airdog for 2 weeks. I am happy with it. I wish it filters odors quicker.
