Why maintenance matters
Every purification system relies on replaceable parts that do their job over time. Timely maintenance preserves water quality and system performance; delaying it for too long can reduce performance.
Common signs your filter needs service
You may notice indicators that are commonly associated with a system needing service or replacement:
- A change in the water's taste or smell
- A noticeable drop in water flow
- A long time since the cartridges were last replaced
- Unusual sounds or leaks from the system
Filter cartridges
Filter cartridges — «كارتردج» — are the elements that do the filtering and are replaced periodically. Choosing the right cartridge depends on your system type and stage count.
The reverse-osmosis membrane
In reverse-osmosis (RO) systems, the membrane («ممبرين») also needs timely replacement and is central to performance. Its replacement timing usually differs from that of the cartridges.
What determines replacement timing?
Replacement intervals depend on usage, water quality, and the system type and its stages, so there's no single schedule that fits every home. We explain the right schedule for your system as part of scheduled maintenance.
Scheduled maintenance contracts
To avoid missing service dates, we offer scheduled maintenance contracts and planned visits that include checking the system and replacing parts on time.
How often should filter cartridges be changed?
It depends on usage, water quality, and the system type, so there's no single schedule that fits everyone. We set the right schedule for your system as part of maintenance.
How do I know the membrane needs replacing?
The need to replace the membrane is usually linked to a change in the system's performance over time. Checking the system during maintenance is the most accurate way to determine it.
