These sheets really work, much to my surprise

The central vac in our 15 year old home had become increasingly slow, so I researched the web for suggestions after my other efforts failed (such as holding hand over suction in ten second increments). Learned about these hose sheets, and was skeptical. Tried a wet paper towel with no success, so bought some of these. Ran one of these sheets through each of our four outlets 3-4 times as instructed. I was amazed at all the dirt and dust they collected. The system now runs like new, and I'll use these every month or so now to keep my vacuum system clear. Great find.
