## Regent Big Grey Filter Housings in Oman

Before water from a roof tank or a well reaches the basin or the coffee machine, a Big Grey housing fitted where the supply enters can stop the sediment it carries.

A cartridge usually lasts 6 to 12 months. The housing is rated for water between +5 and +40 °C.

## Questions and answers

### Will it clear brown or cloudy water?

Most discolouration comes from rust and sediment, and it traps those. A tank in poor condition needs cleaning or repair as well.

### Is it good ahead of an RO unit?

Yes. Guarding RO membranes is a common use.

### How often are cartridges changed?

Somewhere between 6 and 12 months, depending on how dirty the supply is.
