Your pool can use any type of filter that keeps the water clean.
Pooled Energy recommends sand filters (media filters) which can be backwashed with glass media rather than sand media. We believe these are also the easiest to maintain and operate. If you have an old or inappropriate filter at the time of installation, we may recommend that you replace it and will be happy to provide a replacement service or you can arrange to do this separately. Please use 50mm plumbing. It is essential that the filter is correctly chosen to match the pump and pool.
