Cartridge pool filters

How to choose a cartridge filter?

Choosing the right cartridge filter for your swimming pool depends on several essential criteria:

• Pool size: the filtration capacity must match the volume of water in your pool. An undersized filter will not be able to provide effective filtration, while an oversized filter could be an unnecessary expense.
• Flow rate: expressed in cubic meters per hour (m³/h), the flow rate must be sufficient to renew the pool water in a reasonable time. Generally, all the water should be filtered in 4 to 6 hours.
• Compatibility with the pump: ensure that the filter is compatible with the power of your pump. A pump that is too powerful could damage the filter, while an insufficient pump will not allow for optimal filtration.
• Cartridge quality: opt for quality cartridges, made with durable materials and offering good filtration fineness.
• Ease of maintenance: a filter that is easy to dismantle and clean will simplify your task during regular maintenance operations.

How to clean a pool filter cartridge?

Regular maintenance of the filter cartridge is essential to ensure clean water and extend the life of the filter. Here are the steps to follow carefully to effectively clean a filter cartridge:

Stop the pump: before any intervention, cut off the pump's power supply to avoid any risk of accident.

Remove the cartridge: open the filter housing according to the manufacturer's instructions and gently extract the cartridge.

Clean the cartridge: clean the filter by rinsing the cartridge with a jet of water, directing the flow between the pleats to remove debris and impurities.

Deep cleaning: for a deeper clean, it is advisable to use a cleaning gun, specially designed for cleaning a cartridge, equipped with a soft brush, or soak the cartridge in a suitable detergent solution for a few hours, then rinse thoroughly.

Model inspection: check the condition of the cartridge. If you notice tears in the fiber, damaged pleats, deformation of the cylinder, or excessive wear on these elements, it's time to change it.

Reassembly: once the cartridge is clean and dry, put it back in the filter housing and make sure everything is properly in place before restarting the pump.

It is important to note that a low filtration flow rate can also be caused by the filter cartridge clogging.

What is the filtration fineness of a cartridge filter?

The filtration fineness of a cartridge filter is an indicator of its ability to retain particles present in the water. Cartridge filters generally offer a filtration fineness of between 15 and 20 microns. This means they can capture particles as small as 15 microns, such as:

Dust: fine dust particles that can settle on the surface of the water.

Pollen: pollen grains carried by the wind, responsible for the appearance of yellow deposits on the water surface.

Algae: suspended micro-algae that can cloud the water and promote the proliferation of other harmful organisms.

Organic impurities: organic residues such as skin cells, hair, or insects.

This filtration fineness guarantees crystal-clear water and reduces the need for chemicals to maintain water quality.

What are the advantages of a cartridge filter?

Cartridge filters offer several advantages that make them a popular choice for pool owners:

• Filtration efficiency: Thanks to their high filtration fineness, they ensure clear pool water by retaining fine particles.
• Ease of maintenance: Cleaning cartridges is simple and does not require specific technical skills.
• Water saving: Unlike sand filters which require regular backwashes, cartridge filters do not require such processes, thus reducing water consumption.
• Compactness: Their compact design makes them ideal for restricted spaces and reduces clutter in your technical room.
• Simplified installation: It is easy to install and generally less expensive than other types of filters.

At Poolplanet, we have chosen to offer you a range of cartridge filters from Hayward and Pentair, known for precise filtration.

How does a cartridge filter work?

The function of a cartridge filter is based on a simple but effective principle:

Water suction: Water containing impurities, sucked in by the pump, is directed to the filter.

Filtration system: Water passes through the pleated filter cartridge. These pleats increase the filtration surface, allowing a large amount of debris to be retained without quickly clogging the filter.

Water return: Once filtered, clean water is returned to the pool, thus ensuring continuous circulation and optimal water quality.

This looped process ensures that the pool water remains clean and clear for the comfort of swimmers.

What is the lifespan of a cartridge?

The lifespan of a filter cartridge depends on several factors:

Water quality: Water containing many impurities or that is unbalanced can clog the cartridge more quickly.

Pool usage frequency: The more the pool is used, the more debris the cartridge will have to filter, which can reduce its lifespan.

Regular maintenance: Proper and regular cleaning extends the lifespan of the cartridge and reduces clogging.

On average, a quality cartridge can last between 1 and 3 years. It is essential to monitor its condition and replace it at the first signs of wear or degradation to maintain effective filtration.

What type of filter for above-ground pools?

Above-ground pools have specific filtration needs due to their design and use. Cartridge filters are particularly suitable for these types of pools for several reasons:

Ease of installation: Their installation is simple and does not require major structural modifications.

Compactness: Their small size is suitable for the limited spaces often associated with above-ground pools.

Efficiency: They offer fine filtration, ensuring clean water even in small pools.

Water saving: Unlike sand filters which require frequent backwashing, cartridge filters help limit water consumption.

For above-ground pools, it is recommended to opt for a cartridge filter whose flow rate corresponds to the volume of water in your pool. There are models suitable for all sizes of above-ground pools, from small inflatable pools to large tubular pools.

How to install a cartridge filter?

Installing a cartridge filter is an essential step to ensure effective filtration of your pool. Here are the steps to follow:

1. Choose the filter location: Place the cartridge filter near the pool, on a stable and flat surface, protected from bad weather if possible.
2. Connect the pump: Connect the filtration pump to the filter inlet using the supplied hoses and the complete connection kit. Make sure the fittings are tight to prevent leaks.
3. Water outlet connection: Connect the filter outlet to the water return circuit to the pool.
4. System check: Before starting, check all connections and make sure the cartridge is in place.
5. Start-up: Start the pump and monitor the proper functioning of the filter. Water must circulate correctly without leaks or abnormal noises.
   
   

Once installed, your cartridge filter is ready to ensure clear and healthy water. Don't forget to perform regular maintenance to maximize its performance and extend its lifespan.

Cartridge filters are essential devices for keeping your pool water clean and clear. Particularly suitable for small and medium-sized pools, these filters use a cartridge to remove impurities from the water, thus ensuring a pleasant and safe swim with optimal filtration quality.
