Recently I have realized that the the performance of my CV1800 has degraded dramatically. I have a good sized shop (24 x 36) with 13 ‘ ceilings. All my runs are 6”PVC. When I installed the system in 2014 it would try to suck your hand off your arm. Now it’s not much better than my shop vac. I have gone over all my connections, resealing where it was suspicious. Nothing obvious. I’m wondering if there is a lifespan on these Wynn filters. Could that be the restriction? I’ve beat on it and blown it. Is there a life span?
