Editorial Review:
Includes 3-Speed Ambient Air Cleaner - 50-875, 1/5 HP, 60 Hz, 1,025 RPM, 120 Volt Single Phase Motor, (4) Eye Bolts & Flange Nuts, Rubber Feet, 6 ft. Cord, Remote Control, Instruction Manual.
Wood fibers and dust particles suspended in the air in your shop or home are a major safety concern that needs to be addressed. Delta's 50-875 Air Purifier will filter dust and particulate matter down to one micron in size (i.e. tiny). The Delta 50-875 not only filters all the air in a 20- by 20-foot room but it does it at a rate of 13 to 18 times an hour. The unit has a three-speed air cleaner to handle the most serious dust or particulate problems and the remote control allows the user to change speeds or set the built-in timer from any point in the shop. The filter's system consists of a 3-pocket inner filter, a pleated outer filter and an electrostatic pre-filter. The unit's overall dimensions (24 by 30 by 12 inches) and weight (50 pounds) mean the Delta 50-785 Air Purifier can be placed almost anywhere in the home or shop and can even be hung from the ceiling using the four eye bolts and flange nuts included with each unit. -- C.

Arrived defective... like many others have commented:
I was really excited to get this but it arrived defective. The box was fine. No dings from UPS but the fan was out of kilter and rubbed the side of the housing. My carpenter tried to fix it but it was too far gone to address. Delta seems to really have some quality issues. I put into amazon for a relplacement and will try one more time. I really like the concept but I need the unit to work. The replacement process with amazon was very easy to do online.
Shop air cleaner:
The air cleaner works well. I especially like the timer, it can be set to run for 1/2 hour or longer and then shut off automatically. I set the timer to better clean the air after doing some work and do not have to return to shut the cleaner down. The gage on the side of the unit is supposed to show when the filters are getting clogged. I do not think it is very accurate because new out of the box the gage shows that the cleaner almost needs a filter change. I almost did not buy the unit because... more info
Woodworker:
This filter was installed in a basement workshop and suspended from the flooring beams above by chains. There is no noticeable vibration and the noise, even at high speed, does not bother the wife in the upstairs area. I was able to get it in place by myself, but this is best accomplished by two people. It moves a lot of air, and so far, after only a month of service, I'm pleased with the unit.
Good filtration:
For the price, this unit is a good buy. I do a lot of fine sanding of exotic woods on my lathe (220 to 400 grit) and this filter has eliminated a lot of the sawdust "drift" from my workshop. It has good airflow although there seems to be some leakage around the primary filter when it's loaded. I put a telltale on the exhaust and it doen't seem to indicate a drop in airflow when the filter is obviously clogged. You can clean the filter easily with a shop vac, just don't forget to do it frequently.
