Pool filter cartridge cleaning is necessary to maintain the high level of filtration you expect from these popular units. They've grown steadily in popularity with residential pool owners partly due to their high performance when it comes to reducing water particulate and because they don't require a backwash. With a regular maintenance routine you can count of sparkling clean water for many years.
A salt water pool system combined with clean filter cartridges will produce unmatched water quality that will be sure to impress your friends and neighbours. When it's time to replace the cartridges it's important to find the cartridge paper that's compatible with your specific filter. They come in variety of shapes and sizes depending on the manufacturers and there's differences even among the major pool hardware brands.
An indicator that your cartridge filter needs to be cleaned is that your pool water isn’t as clear as it should be. If your cartridge filter is equipped with a pressure gauge you should clean your filter when the pressure rises 10 lbs above the original starting pressure. This rise in pressure is due to debris blocking the normal flow of water that means your filter will not be working optimally.
It’s important that cartridge pool filters are not backwashed like sand or diatomaceous earth filters. The paper filters that are found inside the filter are quite sensitive and a backwash will actually damage them. The papers will need to be removed and cleaned much like a vacuum filter needs to be cleaned occasionally. Precise pool filter cartridge cleaning will vary with different makes and models but a good basic guideline is as follows.
Regular cleaning will ensure your pool remains clean at all times and will extend the life of your filters. Filters should be replaced every 2 to 3 years depending on usage. A larger filter will generally need to be cleaned and replaced more often and vice versa for a smaller filter. After a few times cleaning your cartridge filter it will become second nature. Pool filter cartridge cleaning is something that can be done by any pool owner on your own and will prevent having to call out a pool professional.
If you need to replace your cartridges, use the make and model of your specific unit and it should be located on a sticker on the top or side of your filter. If it's not legible or not attached to the filter you can measure the cartridge. Measurements should be taken for the length top to bottom of the cartridge and the diameter outside edges.
