Cartridge Filters

The delivery time depends on the product reference, availability, and destination of the order. Check the information shown on the product page before completing your purchase.

Orders over €100 qualify for free shipping to mainland Spain, except for products subject to special transport conditions.

If you need to replace the equipment urgently, pay particular attention to the availability and estimated delivery time of the chosen model. You can also browse our complete range of pool filters.

To choose the right one, you must consider the pool volume, pump flow rate, filter area, and the installation's hydraulic characteristics.

The filter should not be selected solely based on the pool's cubic metres. The pump and filter must operate within the flow-rate ranges specified by their manufacturers.

Also check the working pressure, connections, and available space to open the filter and remove the cartridges during maintenance.

Check that the flow rate provided by the pump is suitable for the filter's operating range.

You should also check the connections, maximum working pressure, and other hydraulic specifications indicated by the manufacturer.

A more powerful pump does not necessarily provide better filtration. Excessive flow can cause the system to operate outside the conditions for which it was designed.

The safest approach is to identify the brand, model, and exact reference of the original filter or cartridge.

Dimensions are also important. Depending on the cartridge, check the height, outer diameter, inner diameter, and the design of the ends or connections.

Two cartridges with similar dimensions are not necessarily interchangeable, so we recommend using the measurements to confirm compatibility, not as the sole selection criterion.

The filter surface area is one of the important factors when comparing this type of filter, but it should not be analyzed in isolation.

It must be considered in relation to the operating flow rate, pool size, filter characteristics, and planned maintenance frequency.

Use the manufacturer's recommendations and specifications to choose the appropriate model rather than assuming that a larger filter surface area is always better for every installation.

Generally, cartridge filters are cleaned by removing the filter elements and eliminating the accumulated dirt according to the procedure established by the manufacturer.

This distinguishes them from conventional sand filters, which typically use backwashing to clean the filter media.

Since they normally do not require periodic backwashing, a cartridge system may be a good option for installations where reducing the water discharged down the drain during maintenance is desired.

There is no universal frequency. It depends on the amount of dirt, filtration hours, pool usage, and the equipment's filter surface area.

The pressure gauge can help detect an increase in resistance compared with the usual pressure of a clean filter. Follow the cleaning criteria established by the equipment manufacturer.

Rather than cleaning solely according to a fixed schedule, it is advisable to monitor the filter's behavior and its baseline pressure.

Remove the cartridge following the manufacturer's instructions and eliminate the accumulated dirt using the procedure recommended for that filter element.

Avoid using tools, products, or cleaning methods that could damage the pleats, fabric, seals, or structure of the cartridge.

Before reinstalling it, check that it has no cracks, deformation, or deteriorated areas.

There is no number of months or seasons that applies to all cartridges.

Its lifespan depends on factors such as operating hours, accumulated dirt, water quality, cleaning frequency and method, and the characteristics of the filter element itself.

A cartridge may need to be replaced when it is damaged or deformed, or when, after proper cleaning, it continues to show a loss of performance attributable to the filter element.

An increase compared with the usual pressure of the clean filter may indicate that the cartridges are accumulating dirt and offering greater resistance to water flow.

However, the pressure gauge reading must be interpreted in light of the operation of the entire system.

If the pressure remains abnormal after properly cleaning the cartridges, inspect the system and consult the manufacturer's instructions before assuming that the cartridges need to be replaced.

A compatible replacement can be used provided it is specifically indicated for the corresponding filter reference or model and meets the necessary specifications.

It is not enough for the cartridge to have approximately the same dimensions.

Check the equivalent reference, dimensions, end configuration, and any other indicated specification to ensure proper installation.

Cartridge filters are available with different flow rates and filtration areas, including models designed for higher-capacity installations.

Therefore, they should not be considered solely a solution for small or above-ground pools.

The choice will depend on the required flow rate, installed pump, filtration area, operating conditions, and planned maintenance.

Both systems can provide adequate filtration when correctly sized, but they have important maintenance differences.

The cartridge filter uses removable elements that must be cleaned periodically and normally does not require backwashing. The sand filter uses a granular filter medium and can generally be cleaned by backwashing.

The choice depends on the size of the installation, flow rate, availability of water for maintenance, space, and user preferences.

It can reduce the water used for certain maintenance operations because it normally does not require the periodic backwashing associated with a sand filter.

This does not mean that the system does not use water during maintenance, as the cartridges also need to be cleaned.

The actual savings will depend on the installation, cleaning frequency, and procedure used.

The warranty depends on the manufacturer and model, in addition to any rights applicable under the relevant regulations.

Manufacturing defects must be distinguished from wear of the filter elements and damage resulting from incorrect installation, use, or maintenance.

Keep the invoice or proof of purchase and follow the instructions provided by the manufacturer.

For online purchases, you have the applicable withdrawal rights in accordance with the regulations and the applicable sales conditions.

The general withdrawal period for distance purchases in Spain and the EU is 14 calendar days, although the relevant conditions and possible exceptions must be taken into account.

If you have questions about the equipment received, check its compatibility and review the return conditions before installing or using it.

Check the availability status shown on the product page when placing your order.

Availability may vary between models, so not all filters necessarily have the same shipping time.

If you need to replace the equipment urgently, check the information for the specific reference before completing your purchase.
