Flush every time

Run water through for 5 to 10 minutes after installing or replacing filters, before drinking it or reconnecting your ioniser.

Disconnect your ioniser first

When replacing filters, always disconnect your ioniser and flush the system before reconnecting it.

Use the right tool

Stainless steel above sink housings open with the black handle tool. Older plastic systems use the white spanner ring.

Tank or bore water?

Fit a washable 5-micron sediment filter at your tank or bore outlet so the UltraFilter doesn’t clog.
