Understanding Pool Filters

The filtration system is one of the most important parts of your pool, to keep it looking and feeling clean.

The filter works in two ways:

  1. It keeps the water looking great by removing debris and oxidised materials from the water; and
  2. Stimulates water flow throughout the pool, distributing chemicals and preventing algae from forming in poorly circulated areas.

The water gets forced through the filter where undesirables are trapped and the filtered water gets sent back into the pool.

It’s important to note that filters don’t remove algae or bacteria, that’s the job of chlorine. So, it’s essential to keep the filter clean and keep your pool’s chemicals in balance.

Pool filters in Australia will most likely use sand or cartridge as the filtration medium.

Although sand filters are most popular in Australia, cartridge filters are great for smaller spaces – using less water and energy. To get rid of the debris however, you’ve got to remove the cartridge and hose it down.

Sand filters are robust, durable, low maintenance and easy to use. They can also be backwashed, which simply means flushing out the dirt by turning the lever on the filter. If you’re in the market, the Hayward ProSeries Sand Filter is a high performance and totally corrosion-proof sand filter.

When choosing or replacing a pool filter, it’s important to first consult your local BioGuard Approved Retailer, as they’ll be able to give you the best advice possible on your personal situation.
