Usually a rise in pressure of about 8 psi is an indication that the filter needs to be cleaned. In the last two and a half months, I have not seen the pressure rise on my filter but I opened it up once after the first month and hosed it down using a regular hose nozzle and again the following month. I use a scum sock which I usually rinse out every day to wash out the pollen and other junk. It takes two minutes and it's a lot less work than cleaning the filter, but even that isn't bad. It's probably easier to clean the filter more often than to wait until it needs to be cleaned but every two days seems extreme. I'm using chlorine by the way.
