Reliable, Low-Maintenance Filtration with Sand Pool Filters

Looking for a durable and cost-effective way to keep your pool water clean? Sand pool filters are one of the most popular filtration systems for both above ground and inground pools. These systems use specially graded sand to trap dirt and debris, returning crystal-clear water back to your pool.

At Doheny’s, we carry a wide selection of sand filters and sand filter systems from trusted brands like Hayward, Pentair, and our own Doheny’s line—perfect for pool owners who want simplicity, performance, and long-term value.

How Do Sand Filters Work?

Sand filters operate by your pump pushing water through a tank filled with filter sand. As the water flows through, the sand traps particles as small as 20 microns—including dirt, leaves, oils, and other debris. Clean water is then returned to your pool.

Over time, the sand becomes clogged with debris. To clean it, you simply backwash the filter, reversing the water flow to flush out the trapped particles. Sand typically needs to be replaced every 5–7 years.

Benefits of Sand Pool Filters

  • Low Maintenance: Just backwash as needed or every 1–2 weeks.
  • Long-Lasting Media: Filter sand lasts up to 7 years with proper care.
  • Cost-Effective: Lower upfront and maintenance costs than other filter types.
  • Durable Design: Built to handle high flow rates and large pool volumes.

Choosing the Right Size Sand Filter

The size of your sand filter should match your pool’s volume and pump flow rate. Here’s a general guide:

Pool Size Recommended Tank Size
Up to 10,000 gallons 16"–19" tank
10,000–20,000 gallons 22"–24" tank
20,000+ gallons 26"–31" tank

Frequently Asked Questions

How often should I backwash a sand filter?

As-needed or typically every 1–2 weeks, or when the pressure gauge reads 8–10 psi above normal.

How do I maintain my pool sand filter?

When your filter pressure rises 8–10 PSI above normal or your water stays cloudy despite treatment, it’s time to clean your sand filter. Routine backwashing can help, but deeper cleaning may be needed to remove oils and debris that clog the sand bed. Check out our blog to learn how to clean your pool filter properly.

How long does filter sand last?

Most pool filter sand lasts 5–7 years before needing replacement.

How do I change the sand in my pool sand filter?

The process involves safely removing old sand, inspecting the filter laterals, and refilling with the correct type and amount of new filter sand. Follow our step-by-step guide to changing sand in a pool filter.

Can I use a sand filter for a saltwater pool?

Yes! Just make sure the filter and valve components are rated for saltwater use.

What’s the difference between sand and DE or cartridge filters?

Sand filters are the most low-maintenance and budget-friendly option, but they don’t filter as finely as DE (3-5 microns) or cartridge filters (5–7 microns).

Sand Filters Guides

  • Sand Pool Filters: How to Change the Sand

    Sand filters for pools are known for typically requiring much less maintenance than other types of pool filtration systems, but they do require some care to stay running at their optimum level. Part of sand filter maintenance involves changing the sand in the filter. Depending on how much your pool is used and what type of filter system you have, the sand will typically need to be replaced about every 5-7 years in order to keep everything running efficiently.

    Over time, as the sand in your filter is run through the system, the granules become smoother and the sand filtration process becomes much less efficient. When your sand filter stops working as well, that means it’s pumping harder and harder and overworking to do what should be a simple job. Keeping up with changing the sand on a schedule will help keep everything running smoothly and help to keep your filter running for as long as possible.
