The length of time to go between pool filter cleanings all depends on the type of pool filter a pool is using. A professional pool cleaning service can provide this maintenance and will also schedule the next cleaning with a pool owner before they leave.
The most popular type of pool filter is a DE pool filter. Its popular because it catches more debris and junk than other filters. It can also maintain large and small pools and is a huge asset when it comes to keeping the pool crystal clear and safe to swim in.
