Review on 🌀 BlueDri BD-AS-550-GY Negative Machine Airborne Cleaner - Ultimate HEPA Scrubber for Water Damage Restoration Equipment and Air Purification - Single Unit, Grey by Azizah Jefferson

I'm a general contractor and I absolutely hate cleaning up flagstone dust and other hard dust after I've finished the job. This air purifier works 24/7. The end result was worth the investment. Very dirty filter and much less dust in the room than I expected. I also used a zip system and bought an 8 inch duct to direct all of the clean air out of the work area. I definitely recommend it. I can't comment on someone who uses it all day every day, but for me it worked great and made the job site a lot more professional
