Cartridge Filters

Cartridge Filters for Swimming Pools: Accurate Filtration, Low Maintenance and Water Saving

Cartridge filters for swimming pools are purification systems that stand out for their simplicity, low water consumption and ease of maintenance. They are a very popular alternative to sand filters, especially in small installations, removable pools. Their compact design and filtration technology make them a choice for those looking for performance without complications.

why choose these products?

• Fine and efficient filtration: They capture particles down to 10 microns, removing very small impurities such as pollen, dust, microscopic algae or sediments, providing crystal clear water.
• Remarkable water savings: Unlike sand filters, cartridge filters do not need backwashing, avoiding the waste of hundreds of liters each week.
• Low maintenance cost: Cartridges are easy to clean and some models can be reused for several seasons.
• No installation work required: They do not require drainage connections or complex piping systems. They are quick to assemble and are designed to be compatible with most domestic pumps.
• Silent and valve-less operation: The absence of selector valves makes the system simpler, more compact and quieter.

how does it work?

The water is sucked by the pump and sent into the filter, where it passes through the pleated cartridge. This cartridge is made of highly resistant synthetic materials (generally polyester), arranged in the form of pleats that considerably increase the filtering surface.

During the process, dirt particles are trapped in the cartridge. Once the cartridge becomes saturated, this is detected by the increase in pressure in the filter pressure gauge. At this point, the cartridge must be removed and cleaned by simply rinsing with a hose or, in some cases, with a descaling solution if lime or organic buildup is present.

Many modern models have a quick release system (bayonet or clamp type) for easy access to the cartridge without tools.

  • Internal components resistant to chlorine, salt and UV rays.
• Easy maintenance
  • No sand or valves required.
  • Cartridge cleaning with hose and, optionally, specific cleaning products.
• Universal compatibility
  • Coupling with standard pumps (1", 1.5" or quick thread type connections).
  • Suitable for pools with chlorine, salt, bromine or active oxygen.

Buying Guide: Which is the best product for you?

• Small pools, paddling pools or above ground pools (up to 20 m³)
  • Opt for a compact, low-flow, easy-to-clean single cartridge filter. Ideal for seasonal use.
• Medium and family pools (20-40 m³)
  • Choose filters with larger surface area cartridges to increase the time between cleanings. Better if they are reusable.
• Large, heated or daily use pools
  • A double cartridge or high pressure capacity filter is recommended, with more spaced maintenance.
• Areas with water shortages or environmental restrictions
  • The cartridge filter is a very efficient and environmentally friendly option because of its zero water consumption during maintenance.

Explanation of technical terms

• Micron: Unit of measurement indicating the particle size that a filter can hold. 10 microns = 0.01 mm.
• Pleated cartridge: Cartridge with pleats that increase its filtering surface, improving its efficiency.
• Flow rate (m³/h): Volume of water passing through the filter every hour. It must be adequate to the pump and the volume of the pool.
• Working pressure: Maximum pressure supported by the filter. If it is exceeded, there may be a risk of rupture.
• Reusable cartridge: Cartridge designed to be washed and reused several times before replacement.
