There’s nothing better than diving into a clear, cold swimming pool in the sweltering heat of summer. On the other hand, there’s nothing worse than spending your entire summer trying to troubleshoot discolored pool water or figure out how to keep algae from taking over.
Often, the key to a low-maintenance swimming pool lies in your filter. A pool filter that’s too small for your pool or that isn’t cleaned on a regular basis can allow bacteria to build up, leading to green or even brown pool water, scummy buildup, or a foul odor.
“Shocking” your pool with bleach and chemicals can take care of these problems in the short term, but the overuse of harsh pool chemicals in lieu of a properly-working pool filter can place additional wear and tear on your liner and any other non-metal pool components. Read on to learn about the 3 main types of pool filters.
Diatomaceous Earth (DE) Filters
These highly-efficient pool filters gain their power from diatomaceous earth powder. DE powder is made from diatoms – microscopic aquatic creatures whose skeletons and remains act as tiny sponges. When water flows through DE powder, these diatom skeletons remove dirt and grime from the water.
DE filters are fairly low-maintenance. You’ll need to backwash them, remove the used DE powder, and add new powder on a regular basis. Fortunately, DE pool filters have an easy-to-use pressure gauge that gives you a heads-up whenever cleaning is needed.
The frequency with which your filter’s DE powder will need to be replaced largely depends on how often you use your pool. If you and family members are in the pool just about every day, you don’t cover the pool at night, or pets use the pool, you’re likely to have to clean the filter more often than if you use the pool rarely and keep it covered whenever it’s not in use.
These low-cost and low-maintenance filters are often ideal for above-ground pools or in-ground pools that are on the smaller side. Cartridge filters operate by forcibly pushing water through the pleated cartridge to trap dirt, particles, and bacteria. These filters are available in a wide range of prices and sizes, so if you’re considering this type of filter, you’ll want to talk with a pool expert to make sure you’re choosing the best one for your specific needs.
Cleaning a cartridge filter is simple—when the pressure gauge rises, just pull out the cartridge and rinse it thoroughly with a hose; you’ll be able to see firsthand all the debris that it’s been filtering from your pool.
These cartridges are generally replaced every few years, depending on use. One of the keys to a long-lasting cartridge filter is ensuring that the filter you’ve chosen is the right size for your pool, as using an undersized filter can increase wear and tear and reduce its lifespan.
Sand filters are similar to DE filters; however, instead of diatomaceous earth, they filter the pool water through specially-graded silica sand. All you’ll need to do to keep a sand filter running like new is to periodically backwash it and change the sand when you notice the pressure gauge rising.
Sand filters require the least amount of maintenance of the three types of pool filters available. Sand filters are ideal for landlords, first-time pool owners, those who are often away from home during the summer, or anyone who would rather spend more time in their pool than they do cleaning the filter.
