Sta-Rite® System 3® Modular Media Filter holds 50 times more dirt than a regular sand filter. The unique Mod Media design gathers and holds more dirt — so you clean less often. The split tank design allows for convenient access for cleaning or changing filter media while the use of Posi-Lok® clamps enables safe, easy access to filter. The System 3 Filter is durable, lightweight and corrosion resistant thanks to its Dura-Glas® exterior. The sleek, black tank profile blends well into any landscape design. Available in three sizes — 300, 400 and 450 square foot filter areas.
