Frequently Asked Questions (FAQ)

A: Yes, the filter is compatible with alternative filter media such as glass or zeolite, which can improve filtration efficiency. Media is not included. -

A: For optimal performance, the pump flow rate should be between 4–6 m³/h. This filter is suitable for pools up to 30,000 liters (approx. 8,000 gallons). -
Q: Does the 1-year warranty cover shipping costs?
A: The warranty covers manufacturing defects. Shipping costs for returns are borne by the buyer, but we offer free replacement parts for defective components. -
