If you are replacing a filter that forms part of an existing system then your replacement should match the size of the existing filter.
For example if you already have a 20 inch filter and 1.0HP pump on a 20m³ pool then you would still need 20 inch filter, alternatively you would need to replace both the pump and filter with a smaller selection as per our sizing guide below.
