What is a cartridge filter and how does it work?

There are three different types of pool filters. Each has its own pros and cons, but cartridge filters are the best choice for both first-time pool owners and experienced veterans. They require low maintenance and oversight, while keeping your pool just as clean as the other options. If you're renovating your pool, consider hiring a San Diego pool service to install a cartridge filter.

Cartridge pool filters are most common in spas and smaller pools. According to Pool and Hot Tub Village, these have been around for a relatively long time in the pool industry, but recently, they're becoming more popular. They're made from spun polyester and placed inside a tank.

These systems work by pushing water from the pool into the tank. A skimmer collects the larger debris and the secondary basket catches anything that the first one may have missed. The water then passes through the polyester filters, and dirt gets stuck on the screen allowing for clean water to pass by. The chlorine will kill the bacteria that find their way past.

According to Pool Center, a clean filter can trap particles as small as 25 microns in size. When they become dirty, you may notice the pressure gauge rise to around 8 to 10 pounds. At this point, the filter needs to be cleaned in order to become more effective. Call your local San Diego pool service to have them take care of it. However, it'll probably take up to 6 months before you need to do that, unless you have a smaller filter or recently accumulated lots of debris or algae.

Cartridge filters last about three to five years, and then you just need to ask your pool service to get a replacement. To ensure that it lasts longer, experiment with how long you run your system each day. It depends on the pool size and how often it's used, as well as the amount of debris and sunlight your pool sees on average. The good news is that replacing the filter is cost-effective, and it should only run you about $100 depending on how big the screen is.

A nice benefit of cartridge filters is that you don't need to backwash. Instead, your San Diego pool service will clean the tank. This is great for pool owners who don't want to waste water as it saves about 200 gallons a month.
