We could no longer read the digital… We could no longer read the digital display on our APH260 HEPA Air Purifier. We reported this under the warranty and we worked via email with Terry. He quickly sent us a new unit under the warranty. Then he wrote us a few days after we received our replacement unit to make sure everything was ok. Excellent service and follow up.

I have four APH260s I have four APH260s. I had some problems with the digital displays and contacted Customer Service. Julie and Karen were so helpful. They answered all my questions, helped me troubleshoot, and ultimately sent me a new unit completely hassle-free. They were professional and even checked back with me to make sure things were going okay. Really good customer experience.

Great company, great product We had an airthereal filter for maybe 2 months and the display started doing wonky things where you couldn’t quite read it properly if numbers were higher. We reached out to warranty support and they were super quick to respond and ask all the questions and provide options. I was really pleased with the filter to begin with but knowing customer support is so strong, we like it even more. Thank you!!!

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.

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.
