Pool filters are essential in keeping your pool clean and removing unwanted particles like dirt and sand from the water.

Frequently Asked Questions

The best pool filter depends on your pool size, maintenance habits, and water clarity goals:

  • Cartridge pool filters capture very fine debris, require no backwashing, and are popular for residential pools.
  • Sand filters are durable and simple to maintain, making them great for larger or commercial pools.
  • DE (Diatomaceous Earth) filters offer the finest filtration but need more maintenance.
    Brands like Hayward and Pentair pool filters offer quality options in all categories. For most homeowners, a cartridge or sand filter delivers the ideal balance of performance and convenience.

It depends on the filter type and usage:

  • Cartridge filters: every 1–3 years, depending on care and cleaning frequency.
  • Sand filters: replace the sand every 3–5 years, though the tank can last 5–10 years or more.
  • DE filters: grids typically last 3–5 years with regular cleaning.
    High-quality brands like Pleatco pool filters tend to last longer when maintained properly.

The pool pump moves water through the system, while the filter cleans it.

  • The pump creates the circulation that pulls water from the pool, pushes it through the filter media (sand, cartridge, or DE), and returns clean water back to the pool.
  • Without the pump, the filter can’t function; without the filter, the water can’t stay clear.
    Think of the pump as the heart and the filter as the lungs of your pool system.

The standard recommendation is to run the pool filter 6–8 hours per day, long enough to turn over all the water at least once.

In hotter climates or after heavy use, you may need longer runtimes to maintain clarity. If you have a variable-speed pump, you can run it at a lower speed for a longer period to save energy while keeping water clean.

 While sand filters are reliable and easy to maintain, they have a few drawbacks:

  • They filter to around 20–40 microns, meaning very fine debris may pass through.
  • They require backwashing, which wastes water.
  • The filter sand needs replacement every few years.

However, for large or commercial pools, their low maintenance and cost-effectiveness still make them a strong choice.

Yes. Voomi Supply offers Hayward, Pentair, and Pleatco pool filters compatible with most popular systems. Always check the model number or size requirements before ordering, or contact us for assistance.

With proper care, most swimming pool filters last 5–10 years, though the internal elements (cartridges, grids, sand) will need periodic replacement. Regular cleaning and balanced water chemistry significantly extend filter life.
