Scary to think that anyone's filters could look anything like those in the video. Lol. Ads like that make me thinkI'm being had.
I know what you mean. The video demo looks like something you would see at a State Fair or on an Info-mercial at 1:00am.
Just for fun I thought I would try to build a wand out of 3/4 pvc with small holes drilled in it that I could put down the center of the filter to blow the grime out from the inside. It kind of worked, just awkward to hold, and hard to stay dry. I think I am just going to order the thing, if it does not work well I guess I can always use it as a $100 Sprinkler!
