Review on 🌬️ ALORAIR 3 Stage Filtration Air Scrubber: Stackable Negative Air Machine for Industrial and Commercial Use, Heavy Duty Air Cleaner with MERV-10, HEPA, and Activated Carbon Filters - 10 Year Warranty by Paul Curington

The first unit I received was missing the pre-filter and the handles that hold the pre-filter in place. I used the device for several hours and then it stopped working. I contacted customer service and they agreed to send me a new device. After a few days with the new block it's amazing. It moves air properly and is quite quiet. Customer service is also great for this company. I would buy another.
