Pools are great in the summer, but they can be a headache to maintain. Between balancing disinfectant levels, maintaining pumps and filters, and keeping dirt and debris out of the water, pool owners have their work cut out for them.
Fortunately, there are some tips for keeping ahead of potential problems, and much of that happens with the pool filter.
Pool filters typically come in three varieties: sand filters, cartridge filters, and diatomaceous earth (DE) filters. Each type has its advantages, but there are many restrictions on what filters will work, depending on your pool size, pump configuration, and so forth.
Speak to a pool professional to determine precisely what type and size of filter is best for your specific needs.
Sand filters work by naturally trapping dirt, debris, and organic matter in the dense matrix created by the fine grains. These filters require occasional backwashing to break up and wash loose all of the contaminants trapped in the sand. These filters work well, and are easy to clean, making them a popular choice.
Pool cartridge filters tend to be a bit less expensive than sand filters, though they can be more maintenance-intensive. It is best practice to occasionally remove your cartridge filter and hose it off, to free trapped contaminants and debris, and lengthen the filter’s life.
These filters generally have a somewhat larger micron rating than sand filters, though the micron rating will differ from across filters and manufacturers.
Finally, diatomaceous earth filters use a specific type of soil containing diatoms, the fossilized remains of ancient algae and microscopic creatures. The nature of diatomaceous earth makes it an ideal filtration media, with very small pore sizes to trap the smallest contaminants.
There is a tradeoff in cost, however, as these systems tend to be on the pricier side. Cleaning a DE filter is also a multi-step process, usually requiring some system disassembly and cleaning.
Talk to a pool expert to determining which type of filter is best for your needs and situation. For above-ground pools, cartridge filters are often the way to go, because they are relatively inexpensive, and often sufficient for the smaller amount of water in an above-ground pool.
Your local water conditions will also be relevant to determining which filter is right for you.
Keep your pool clean, so you can stay focused on having fun in the sun and water. Choosing and maintaining a pool filter is a breeze, provided you do your research.
