Sundance filters...questions?

We've been told that the pleated SD filter will last up to 10yrs with proper care.  And the microclean section needs to be replaced every 3mo w/water change.  10yrs on the pleated, that sounds like a long time.  He says that as long as the pleats are in good shape, its gonna work.  Said we soak every 6mo, but use a spray cleaner about twice a month, and hose spray every week or so  

True?

I change my micro clean filter every four months when I change water and mineral cartridge.  I expect my pleated cartridge to last maybe three years.  I figure they should last about 18 months and I use two that I swap between every month.  I clean them monthly in filter cleaner.  I generally do not rinse them in between cleanings.

I change the micro filter every water change (3 to 4 months), and clean and swap the pleated filter at that time.  I don't clean the pleated filter between changes, as it doesn't get that dirty.  I swap between 2 filters, and I hope to get at least two years out of them.
Ten years is longer than I'd expect to get, but then again, I only have a year on my tub so far.

Do filters EVER last 10 yrs? Yes, so they really weren't fibbing by saying they can if cared for. Is that a typical timeframe when properly cared for? Certainly not. Since the warranty is long over the salesman isn't making a promise that'll come back to bite him/her and it sure sounds good.
