Customer service is excellent! Airthereal customer service is excellent! After 2 months of using their 27kW tankless water heater, it just stopped heating water one day. I checked a few things and then called up support. They got back to me very quickly and had me test a few more things and send some pictures. Finally, before making me go through the trouble of replacing the whole unit, they sent me a video walking me through how to clean out the water flow sensor and that got me back up and running. Their customer service was prompt, respectful, and most of all, actually helpful.

I ordered my first product (Ozone… I ordered my first product (Ozone machine) from them via Home Depot. Product itself arrived great, early even. Problem was, the hard plastic safety door hanger was snapped/broken. I contacted the co directly, sent a pic, asked for a replacement, they promptly sent me TWO and had EXCELLENT communication with me, even when I was so busy, I couldn't always respond! I would definitely recommend them! Thank you!!!

The support staff at Airthereal was… The support staff at Airthereal was very responsive. They engaged with me on finding the best solution. Eventually it was decided they needed to replace the unit. They had a new one shipped to my house immediately. Great customer support. Highly recommend!

The products are quality and work well The products are quality and work well. I have multiple ozone generators including the WiFi ones and a portable one for car/fridge. Also the solar for water purification and one for ozonating water for cleaning things. They do well what they are supposed to do, but don’t expect a polished app or apple-level-user experience. However do expect reliability and robustness, that is why I’m giving 5 stars. Although the app needs to get fully translated from Chinese and some bugs cleaned up. The devices are still great at their basic functionality. I’m satisfied.

Excellant customer service I haven't run across many companies providing the kind of service Grace at Airthereal gave me, all done by email. She quickly offered several options to rectify a problem with the unit. I chose the replacement option on Dec. 18 which was delivered Dec 24th. Amazing, given the Christmas delivery crunch.
