Sand filter

The device is a container filled with sand, which serves as a filter material. These filters can be equipped with additional elements:

  • Backwash valve to regulate operation
  • Pressure gauge for pressure control

Sand filters remove particles as small as 20 microns. They are affordable, have high performance and a long service life.

Advantages of the Emaux V350 sand filter:

Filtration efficiency: With a flow rate of 4 m³/h, the Emaux V350 effectively purifies pool water, removing even the smallest impurities.

Compact size: With a body diameter of 355mm, this filter is ideal for small to medium sized pools without taking up much space.

Durability: Thanks to the housing material, the filter is resistant to corrosion and other external influences, ensuring a long service life.

Easy to operate: Emaux V350 is easy to operate and maintain, including sand replacement.

Cartridge filter

Contains replaceable cartridges that need to be cleaned and replaced periodically. They can filter particles down to 10 microns, save water and energy, but require frequent maintenance and are more expensive to operate.

Diatomite filter

These are the most effective filters, removing particles down to 1 micron. They use diatomite, a rock. They are the most expensive and are most often used in commercial pools.

How to choose the right filter

  • Determine the filter performance based on the volume of the pool. For example, for a pool with a volume of 50 m³, it is necessary to filter 125 m³ of water per day (50 m³ * 2.5 is the mandatory minimum number of water turnovers per day).
  • Consider pool occupancy, especially for commercial properties.
  • Choose filters from well-known and reliable manufacturers to guarantee quality and durability: Emaux, Waterline, Hayward, Aquaviva.
  • When choosing a filter, you should also consider ease of maintenance and operating costs. For example, although cartridge filters are more compact and use less energy, they require cartridge replacement more frequently and can be more expensive to maintain than sand filters.
  • Consider where your pool is located. Pools located in areas with a lot of trees or dust may require larger filters due to increased contamination.

If the pool is used regularly and heavily, this may increase the need for a more powerful filtration system. For detailed and accurate selection of equipment, consult with specialists.

The right filter will keep your pool water clean and safe, ensuring a comfortable experience throughout the swimming season. Choosing the right filter is important not only to maintain the hygienic safety of water, but also to reduce the cost of maintaining the pool.
