The Bestway Flow Clear Sand Filters makes an extremely efficient and environmentally friendly upgrade to a standard filter pump. It’s also a cost-effective way of circulating clean, clear water so that your pool is fresh and hygienic. The sand filter pump filters the water through silica sand, which only needs to be replaced once every three years. The above ground pool sand filter even has a strainer to prevent leaves, twigs and large debris from blocking the filtration system as water gushes through! Designed to be simple, this pool sand filter pump is equipped with an easy to read pressure gauge, 360 degree rotation top flange clamp and the easy access design keeps the maintenance simple. Controlling this pool filter pump is even easier with the 6 position valve so you can choose a mode with a flick of a switch. Durable and corrosive proof, this frame pool cleaner will keep your pool clean all summer long. Ideal for inflatable and frame pools such as Fast Set pools and Steel Pro Frame pools.
