I once had a P-Matic dust collector - filter bag above, plastic bag below. I could fill the plastic bag in 20 minutes if I was planing wood. Some days could get 4-5 bags. Pick 0 to 5 of them up and haul them out the door, every day.
I aded up the time I spent handling those damn bags, and reconnecting the empties, and eating all the dust in between, and realized I was spending a lot of money to handle shavings. This was time I could be doing something more billable. Think about 15 mins a day, 1-1/4 hrs a week, 65 hours a year. Multiply that by your hourly rate, and you will see, as I did, that you are paying for a first rate system, but you do not, and will never have one until you realize where your costs are and do the math.
When I ran the numbers, I called Oneida the next day.
I wanted better collection, and I wanted a large storage container that would empty once a week, or once a month. I built a small room on to the side of the shop, put the fan and motor in the top of the room, and 128 c/f of air tight dust storage, with access only from the outside, at p/u truck height. Life is sweet.
