Frequently asked questions
Is SANDBAG® compatible with my existing sand filter?
Yes. It is designed to fit all standard filter tanks up to 500 kg.
Is it really reusable?
Yes. A simple rinse is enough — SANDBAG® can be reused for several years.
How often does it need maintenance?
In most cases, only one backwash per season is required.
Is the glass used dangerous?
No. The glass particles are rounded, thoroughly cleaned, and safely contained within a recyclable rPET textile bag.
How do I clean my SANDBAG®?
Use the backwash function—ideally when the pool is overfilled after heavy rain—or remove the SANDBAG® units and rinse them with a garden hose.
