The Best Swimming Pool Sand Filters

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

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 chemicals kill the invisible contaminants like algae, spores, and bacteria while the filter takes care of the debris and the particles left behind. That is why it is so important to correctly size and install a suitable filter to have a crystal clear pool!

Before we go over our recommendations for the best Pool Sand Filters, let's see what the Sand Filters are all about so you can easily get why we chose these particular sand filters to recommend.

The Six Settings of Sand Filters

Sand filters always have a six-port valve with different settings. They are as follows:

Filter: This is what your sand filter does 99% of the time, it filters the swimming pool water.

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 debris to be vacuumed completely out of the pool. Please note that this setting empties your pool.

Backwash: This is a short cleaning cycle of the sand to improve filtration. It is recommended that you do this once a fortnight in summer and monthly in winter.

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 and not blown back into the pool.

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.

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 the water is closed to service equipment.

General Maintenance Tips for Sand Filters

Periodically, you will need to perform some basic checks on your filter to ensure smooth operation, these are outlined below:

Timing Maintenance Check Service Action (if required)

Fortnightly (Every two weeks)

Check inlet/outlet O-rings for leaks.

Annually (Once a year)

Compare operating pressure of backwashed filter to initial pressure (when new).

If pressure is more than 10psi different from new filter pressure, a sand change may be required.

Sand filters are the most effective way to keep your pool water sparkling clean. They require little maintenance and will remove impurities, such as dirt, leaves, grass, hair, body oils, sunscreen and even bacteria, from the water. As dirt accumulates in the sand particles over time, you only need to backwash the filter by simply reversing the water flow.

Sand filters have a reputation for durability and performance, and are ideal for small to large domestic swimming pools. They are designed to give maximum performance with superior filtration for sparkling clear water and are compatible with sand or Zelbrite, an advanced filter media which filters finer than sand and gives your pool greater clarity and sparkle.

Conclusion

Think about the type of pool you have and the size of your pool. These are the two main factors you need to consider when choosing 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 small pool, depending on how dirty it gets. Most of the time, filters will specify the size they’re used best for.

So which do we recommend?

They're all good! (We wouldn't carry them if they weren't) but for the best bang for your buck, we highly recommend the Water TechniX 25inch Sand Filter Aspire. It does everything that all of the other sand filters can do at a fraction of the cost. Another reason why we love it is because of its simple backwash setting and its glass viewport which makes backwashing a breeze.

Of course, here at MPM we're really all about the warranty. On top of the 10-year warranty on the tank, the Water TechniX 25inch Sand Filter Aspire is the only one of the four that provides a two-year warranty for the valve and the gauge!
