Well made, poorly described
This product is actually TWO one micron bags for an 850. It contains both the top and bottom bags. Same belt loop construction as the original 30 micron bags. Don't see the usual vapor cloud of fine dust suspended in the air so I assume they are working as they are supposed to. Bags have no company logo and have the blue marks to indicate where they should be stitched. Not a very professional appearing product but it is priced right and seems to clear the air.

Micron Bag A Must
After reading some critical reviews about the quality of manufacture, i.e. Poor stiching, loops not properly positioned, I was concerned about the quality of this product. The two units I received were well made and have been an important addition to my confined shop space with many different power tools. This filter is attached to my 1.5 HP Delta unit. For those who are not aware that the standard filter bag that comes with the unit filters down to only 30 micron particle size. This bag filters down to 1 micron and makes a big difference in the residual amount of fine particles that are released into the shop environment. I highly recommend this product for better woodworker health.

buy em...worth it
I bought this to go with the Delta 50-850. It fits fine. Two come with the order so it's not as pricey as you'd think.

From all I've read, you want to get these. If you've gone this far to buy a dust collector, don't skim on the last part that will stop tiny dust from blasting back into your workshop.

Delta 1 micron let down
Cheap Cheap Cheap... Sure they are 1-micron dust bags... My Grandmother could have done better at sewing a bag together... Ink marks and no double stitching on the loops... In fact it appears to have a loop missing.... Again how can Delta hold there heads up with charging so much for a crappy crafted piece of material.... The original bag was made better by the Asians so why can the US made products at least muster up to their quality?? Not even a Delta Logo on the bag... a waste of money in my opnion.... your better off just throwing a sheet over your dust collector with the original bag on it.... probable just as effective or perhaps better....

Cleaner air! Increased airflow! Works great[.]
I just installed my 1-micron bags. What a difference! It's true, the 1-micron bags do not inflate up hard like the original bags that came with the dust collector. Since the 1-micron bags allow so much more air to pass through more easily, do not expect them to be inflated hard and stiff. The 1-micron bags have less resistance to air flow. To test, I held the original bags and the 1-micron bags over my mouth to see how breathable they were. The 1-micon bags were very easy to breath through and the original bags were very restrictive. I purchased the 1-micron bags for two reasons, (1) I breath anything that the bags do not collect and (2) I started noticing a very light dust covering over items in my storage room where I also keep the dust collector after about 2 weeks of use (I just installed my dust collection system.) I can only imagine what it would look like after 2 years with the original bags. Keeping things clean is the original reason I bought the dust collection system in the first place. My only negative is I think these bags are a bit pricey but I still worth a 5-Star rating.
