Review on 🌬️ Air Choice Home Air Purifier - Ultra Quiet Bedroom Air Purifier for Homes up to 1485 sqft - True HEPA H13 Technology Removes 99.97% Hairs, Dust, and Smoke - White by Lisa Holland

This is an addendum to my original review. I bought this product a few weeks ago and was so impressed that I bought a second unit for another room a few days later. For reasons unknown, one of the units started running with a red light and a much higher fan speed. A red light indicates an indoor air quality issue. It made no sense since nothing in the room had changed. I brought the second unit and when turned on it showed a blue light that the air quality was fine and was working in "automatic mode". Apparently one of the devices was not working properly. I am very disappointed because initially I liked the performance of this product but I have to question both the reliability of this item and its long term performance. While it comes out of the box, I'm concerned about how well made this product is actually and how valuable it is given the high cost.
