The Best Swimming Pool Sand Filters

5 minute read

Apart from the swimming pool pump, the next most key piece of equipment is the “lungs” of your pool, the filter! With an undersized or poor performing filter your pool will turn into a green nightmare full of debris and dirt, making it swamp that no one would want to swim in.

This is a guide to what we think is the Best swimming Pool Filters -

When it comes to having a pool, dirty water has the potential to make people very sick, which is why knowing how to keep your pool clean by combining a high-quality pool filter and the right cleaning chemicals is so important.

Many pool owners have the misconception that the pool filter will sanitise the water, which is not the case at all! That is done by chemicals circulated through the pool. The filter is one part of the circulatory system of the pool. Its job is to catch debris, so as to limit the particles floating out in the pool. That is why it is so important to correctly size and install a suitable filter to have a crystal clear pool!

The six settings of the sand filter 

The sand filters always have a six-port valve with different settings.

  1. Filter: This is what your sand filter does 99% of the time, it filters the swimming pool water. 
  1. Waste: In this position, the water runs directly out of the filter, bypassing the sand. This is used when the pool is excessively full or needs the debris to be vacuumed completely out of the pool. Please note: this setting actually empties your pool.
  2. Backwash: This is a short cleaning cycle of the sand to improve filtration (see 'Maintenance of your swimming pool filter'). It is recommended to do this once a fortnight in summer and monthly in winter.
  1. Rinse: This setting is used directly after backwashing. Allow the water to run through the filter from top to bottom for 30 seconds. This ensures all the sand is put back in place and that any remaining dirt is drained away, not blowing back into the pool 
  1. Circulation: The water runs from the pump directly back to the swimming pool without going through the pool filter. This means the water isn't filtered. 
  1. Closed: All ports are closed. If your pump is still on, make sure to switch it off within seconds as the pressure builds up incredibly fast! This setting is generally used if the pool is below water level and you need to ensure water is closed to service equipment.

General maintenance tips of your sand filter

Check pressure gauge. If pressure increase is greater than 5psi cleaning may be required.

Davey's Premium Crystal Clear Sand Filter Information


Think about the type of pool you have and the size of your pool. These are the two main factors in installing the right filter for years of maintenance-free poolside fun.

Larger pools will need larger filters, but you might want to use a large filter on a mid-size or even small pool, depending on how dirty it gets. Most of the time, filters will specify the size they’re used best for, but unless otherwise stated
