They are the unsung heroes of pool maintenance. They’re expensive, but they make your pool healthy and clean, so it’s worth having. It’s not as simple as just putting one in a pump and turning it on, though. Pool filters needs specific care to function properly, and possible maintenance will create a huge improvement in your filter’s performance.

There are three main types of filters: sand, cartridge, and DE (diatomaceous earth). All three have advantages and disadvantages. But if you need help deciding which is best for you, we can help.

Sand filters are the oldest type of filter system, but that doesn’t make them obsolete. They require more care than cartridge or DE systems because they must be backwashed every few days with a garden hose or power washer to flush out the dirt and grime from the swimming pool’s water. However, sand filters have been shown to work better in colder climates because they won’t freeze up during winter months like other types of filters can.

Cartridge filters and DE filters both have their advantages. Both are highly efficient at trapping dirt, but both need maintenance and can be very messy. The biggest drawback to cartridge filters is that they require regular replacement. Cartridge systems generally last three to six months, while DE lasts three to six years.

So if you don’t have time to spend on your pool’s filter system, a sand filter is an affordable solution—and if you’re not using your pool this summer, a sand filter is the only filter that will last throughout the winter. When you’re ready to start using your pool again in the spring, backwash your sand filter, and you’ll be good to go.

No matter which type of above-ground pool filter you choose, ensure the unit is of a reputable brand that is easy for you to take care of. Whether it’s DE, cartridge, or sand filters that will work best for you depends on how much time and effort you want to put into your pool’s maintenance.

Additionally, if you have a DE filter, ensure you get a pump with a DE filter system, so the water is filtered through the pool’s return lines. This will keep your swimming pool’s water clean and clear.

Sand filters are by far the most economical of the three above ground pool filters, and they’re also more convenient than cartridge systems. As long as you perform regular maintenance on your unit, it will last several years without needing expensive repairs or replacement parts.

Cartridge filters are very efficient at trapping dirt, but they do need to be replaced regularly. They are also much more expensive than sand filters and don’t last as long as DE systems do.
