BlueDri BD-AS-550-GY Negative Machine Airbourne Cleaner HEPA Scrubber Water Damage Restoration Equipment Air Purifier, for Commercial Use, Gray

We bought this to use during a huge demolition project in which 3900 sq feet were taken down to the studs, all insulation, flooring and pretty much anything else we could get our hands on was removed. We recently had a flood in our home and the restoration company had brought in this units much more expensive competitor and left them behind for us to use for awhile, after they picked them up we decided we were so impressed wth how well they worked that we needed one to buy for our upcoming much larger project, however we weren't impressed with the competitors pricing- so I found this product and couldn't be happier! It works just as well as the other one and is actually a fair bit quieter than the other ones- it's still noisy but at a more tolerable level. It's actually much less expensive to buy this unit than to rent one even for just a few weeks!!This past weekend we removed all the insulation from our ceilings. We have a relatively flat roof which we found out while removing the insulation that it had at one point been a tar and gravel roof now replaced with a membrane roof, however you can imagine the amount of dust, stones, mold and whatever else was up there since the 50's -pretty much the most disgusting insulation you've ever seen. When we were taking it down you couldn't see across the room - the air was literally black. So we we finished our job, picked up all the insulation and left the air scrubber running. 20 minutes later we returned and the air was totally clear!!! ( we still had to wear masks but the difference was incredible and saved us a ton of cleaning!) We vacuumed off the unit and opened up the hepa filter and vacuumed that off as well and were able to keep working rest of the day- without this machine the dirt and dust in the air would have lingered for many many hours!Couldn't be happier with this machine!

Very impressed with air quality after running this in a number of different scenarios.Has 8" exhaust nozzle to attach a flex line too if you want to remove the filters and just move air away.

This is a great little air scrubber. I purchased for a job requiring a containment and this exceeded expectations. I wish the company included an exhaust hood to direct exiting airflow in particular direction. If necessary, customers can probably spend another $100-200 for a flexible exhaust duct. The pleated pre filter is 16x16x1 merv 8.. only a few dollars at the home center. Will likely buy more of these for various job sites.

I love this unit! I use it for my dogs and it helps so much with their dander. Will buy again!

There are two drawbacks when considering this machine.1. The pre-filters are way overpriced. They are just cheap furnace filters and cost over $158 for twelve.2. The clips that hold the pre-filter in place are so tight and oddly positioned, making it challenging to get the old filter out and placing a new filter in the unit.I am going to purchase another unit but not from this manufacturer. There are air scrubbers that have washable pre-filters. Even if they cost a little bit more money, it's worth it in the long haul. The pre-filter only lasted three days, and they only send ONE with the unit. This unit will cost more over time because you have to replace the filters often.

Large device, very light, amazingly fast. Removed mold particles from air!

We have run this for 279 hours and it works exactly how we wanted it to work. It scrubbed particulates from the air and took the funk out of a moldy area. If you tried to rent this...you would pay one third of this price for one weekend. Sure, the filters are going to be pricey...but you pay for quality.

GreatWorks really wellGets rid of smells
