How to Clean a Pool Filter
September 16, 2021
Cleaning your pool filter is how you keep your pool clean. If you don’t clean it, there will be dirt and other things in the pool that can make your water unpleasant and unsafe. It’s important to keep the water clean so that everyone can have a good time swimming in it!
How do pool filters work?
The pool pump pulls water from the skimmer and main drain on or near the bottom of your pool. The dirt, debris, bacteria are filtered out after which it flows through plumbing to a heater (if you have one) and salt chlorine generator if you have a saltwater swimming pool. The clean water returns to the pool through the return jets on the pool walls.
What are the three different types of pool filters?
To maintain a clean and healthy swimming pool, the filter is going to be one of the most important pieces. There are three different types of pool filters. They each have different qualities that make them better for certain purposes.
1) Cartridge or Closed-cell Foam Filter: a cartridge filter is made up of a porous material where dirt particles and debris are trapped by the air pockets in the foam. This type of filter doesn’t usually need to be replaced and it can last up to 3 years. It’s a good choice if you don’t plan on swimming very often because the dirt doesn’t get back into your pool water, but it can be wasteful with how much water it pulls out before dumping it back in.
2) Sand Filter: this type of filter uses sand to trap dirt particles and debris and then cleans them out of the pool. This system doesn’t need to be cleaned as often (2-4 weeks) because it filters larger particles more effectively. It’s important to note that this type of filter isn’t used very often anymore due to how much time it takes to maintain and how expensive it can become over time as sand gets trapped inside of the media.
3) Diatomaceous Earth Filter: this filter uses a specially formulated filtration material called DE powder (diatomaceous earth powder). Once you insert this material into your cartridge or sand filter, it works like a magnet that traps dirt in microscopic holes where water has no choice but to flow right through it. This is how this type of works so there’s less pressure on how often you have to clean it which is why it’s probably the most common type.
The best way to keep your pool filter working for as long as possible is by regularly cleaning and changing out the media when necessary. The more dirt that builds up inside of the media, the less effective your filter is so it’s important to stay on top of how often you’re having to clean it.
