Does anyone have any direct knowledge of or experience with the Pentair "Clear-pro Technology"?
I am in the market for a new sand filter. Some of the Pentair sand filters are equipped with what they call "Clear-pro Technology". These models cost 15-20% more than their standard counterparts depending on where you shop. Some places list the various models at the same price The only difference is that the center tube and laterals are made from a porous material. This is how the Pentair ad copy describes the filter.
"Traditional sand filters can only remove particles in the 50-100 micron range, but ClearPro technology^Â® removes particles up to five times smaller, well below what your eye can detect. When combined with our popular Tagelus^Â® sand filter, your pool will achieve 60% cleaner water than with other sand filters. "
"The secret is a proprietary component inside the filterâ€”an exclusive porous tube water must pass through before re-entering your pool. It creates a final barrier to the small
particles sand cannot stop, including the finest dust particles, algae, and pollens. The result is a level of water clarity never before possible. In fact, Tagelus with ClearPro Technology achieves the same water clarity as legendary diatomaceous earth (D.E.) filters.
I have talked with several pool store people and I intend to talk to at least a couple more. So far nobody around here knows anything about this filter. The big push here is for cartridge filters so nobody knows much else.
My concern is that as the filter ages the tubes will become impacted and resist back flushing. Pentair customer service says absolutely not, and there is no additional back flushing necessary. They also maintain that the filter effectiveness does indeed approach DE. These filters have only been on the market for a little over a year so I'm thinking time will tell. Pentair suggested to me that at some point they may be using these tubes on all their sand filters if they can stay competitive on price. It seems to me that even if these tubes do eventually "stop up", say in 3-5 years, I could replace them with either new ones or standard ones.
Any experience or thoughtful suggestions? (Please no dismissive comments about mfg. hype, etc.)
