How Long Do Pool Filters Last

How Often Should I Clean My Cartridge Pool Filter?

Your swimming pool pump system can expect to pump 60-70,000 gallons of water every 8 hours. Thats a lot of work!

Like all things, swimming pool filters become less effective with age! When the filter has passed its prime, it will get clogged, dirty, and become ineffective.

How long your pool filter will last ultimately comes down to how much dirt it needs to clean. Assuming you properly maintain your swimming pool, you should expect the below timescales on average:

  • – Filter Cartridge approximately 2,000 working hours, usually around 2-4 years.
  • – Sand Filter Media around 3-7 years
  • – Glass Filter Media about 7-15 years

Pool-filter cartridges are used to keep home swimming pools and spas clean. They can be used for pools with a capacity of 30,000 gallons or less volume of water. The filter cartridge is generally made of polyester cloth or corrugated paper that acts as a filter. When the filter is dirty and clogged, the water in the entire pool can become dirty. Check out these guidelines below to know how often you should replace your pool filter to keep your water safe and clean.

General Filter Life

Pool-filter cartridges can run for about 2,000 hours in a filter pump. Usually, filter cartridges have to be replaced once every one to two years. The filter, however, will not last as long if you enter the pool with suntan lotion, deodorants, hair-care products, and other chemicals.

To know when to replace it, you should observe the filters condition. If the cloth looks loose, or if the cartridge looks cracked, its time to replace it with a new one.

Usage and Size


Step 1 – Remove Filter and Rinse

First, remove the filter from the cartridge and rinse it off with a brush and hose, spraying it with regular water. You should repeat this process at least once per week.

Step 2 – Replace Filter if Needed

How Often Should Pool Filters Be Cleaned

The recommended cleaning interval is 1 to 3 weeks, but generally speaking, you should clean a sand filter when needed, there is no set time. The best way to tell if it needs to be cleaned is to use your eyes to check the clarity, flow and pressure. If the water is cloudy, hazy or green, you need to clean your filter. Also, if you dont see any obvious visual signs, check the pressure gauge.

Each pool filter has a different threshold for how long it can go between cleanings and maintain the proper chemical balance of your pool water. The quality of your pool water is a big determinant, and that depends on how often you use your pool and its surrounding environment. However, you can always use the pressure gauge as a benchmark for when you need to clean, regardless of the type of pool filter. If the pressure is 8-10 PSI over its startup level, its time to clean it.

Use the same backwashing technique for DE filters as you would for sand filters. There is no set time for how often you need to backwash a DE filter. The best rule of thumb is to do this when your pool needs it. Pressure is the best marker to determine when to backwash your filter.

Cartridge filters can go up to six months without cleaning but most likely will need to be rinsed sometime after the three-month mark, depending on pool balance and clarity.

  • Broken valvesvalve failure renders your sand filter virtually useless
  • Split tanka ruptured tank will need to be replaced. If you see any signs of fracture, turn your filter off immediately
  • The pressure is too highIf your filter isnt functioning properly, it most likely needs cleaning. Low pressure means less restrictiontoo low could indicate your return fittings are missing. Low pressure isnt a problem as long as the flow is there

Cleaning Pumps And Skimmers

Keep your pumps clean on an ongoing basis by watching the pressure levels. When the pressure is high , backwash them right away. Twice each season, you should clean the pumps thoroughly. Open them up and clean them out completely. This task requires daily, weekly and seasonal attention!

When people ask, How often should you clean a pool? they often dont realize that many factors go into determining this. Clean your skimmers daily if your pool is near trees. If there are no trees around, once a week may be alright.

How To Clean a Pool Filter Cartridge

DarthChicha said:Hi, I have a 10,000 gallon, cement pool in Texas. I bought a new pentair 160340 filter that has cartridges. How often should I clean it? I had read that they should be cleaned every 6 months but the pool guy told me that its every month. :-|Thanks

For your filter, mine has a gauge on top of it. It really depends on your conditions, and how much junk it’s filtering out. My filters gauge was initially setup running at 14 psi, when it gets up around 20 psi, the gauge has a reading that it’s time to clean.

Jeremy — Do not use the dial markings to determine when to clean. Use 25% above clean pressure. Thank you.

Lilypad said:When you have cleaned and reassembled your filter, start it up and note the new “clean” pressure. When it goes 25% above that number it is time to clean. I’ve gone through two of those gauges and am now going to switch to a glycerin one sold by TFTestkits. That black one isn’t very accurate IMO.

Changing Your Pool Filter

Now that weve touched on when to change your pool filter, we need to talk about how. After all, knowing when to replace the filter doesnt do any good if you cant change it yourself.

Luckily, changing the pool filter is extremely easy.

Removing the Filter

Before you can remove the pool filter, youll need to turn off the pump system. If you dont, youll spray water everywhere. Its a mistake most people only make once.

Next, shut off the valves leading into and out of the filter. This stops any extra water from entering the filter while you work. Remove the tubing that connects to both sides of the filter, and youre ready to remove the cartridge itself.

The actual cartridge should unscrew from the housing and drain water. Look inside where the filter was and ensure nothing seems broken.

Replacing the Filter

The actual replacement process involves screwing the new filter into place. Check with both your pool and filter manuals to make sure youre installing the filter in the correct orientation.

Once youve reviewed the manual, you can plug in the new filter and ensure its securely in place.

Reconnecting and Restarting Your Pump

Now that the new filter is installed, you can begin reconnecting the pipes to the filter assembly. First, dry-fit the pipes to make sure they all fit back in place. Next, prime the pipe threads, cover them in Teflon tape or pipe sealant and reconnect all the connections.

Is Pool Filter Cleaning Really Necessary

Like everything else, pool filters are subject to wear and tear. Certain factors, such as poor maintenance, can accelerate this process and reduce their lifespan.

Over time, debris and chemicals build up in the filter. Without proper cleaning, pool filters get clogged and become less effective. This results in cloudy water, bacteria growth, and poor water quality.

Filters also play a crucial role in pool water circulation. They help spread the chemicals you add to your pool and ensure a clear swimming area.

If the filters are clogged, you may experience problems with the pool pump too. It could back up and flood, causing a lot of damage. Regular pool filter cleaning can prevent costly repairs and infectious diseases.

How Do I Know If My Pool Filter Is Bad

There are ways to tell if the swimming pool filter is bad. If the water turns cloudy, then you know that your filter is not functioning properly. Leaking multi-port valves, broken or bad laterals, valve failure, tank failure, and pressure issues are some of the other indicators that the pool filter is bad.
