Air Scrubber for Industrial/Commercial, HEPA Air Purifier with Ion Generator/Light, 4-Stage Filtration, 1100 sq.ft, 900 CFM, Stackable, GFCI Outlet, Heavy Duty Negative Air Machine

Nowhere near as effective as I had hoped. We use this on residential construction projects (kitchen, bath, etc). It does not scrub or move air nearly as much as is needed to control dust. The prefilters are proprietary, don’t last more than a couple days, are expensive, and are always out of stock. I definitely would NOT buy this unit again.

At level 1, it is tranquil, and at level 5, it makes it so I do not hear my kids fighting (so plus and minus to the noise factor). I would only like more clarity on what each level is for. The owner's manual doesn't specify that level 1 is for this and level 3 is for that. But overall, I'm thrilled. It also helped dry the air and improve the airflow without an HVAC system.

It is literally impossible to get filters that fit this thing I called the manufacturer themselfs. They sent me to a link. I paid $56 and never received the filters. It’s been a month. There are no standardized filters that fit this thing I would never purchase this again I would buy something that take standardized filter sizes.
