The sediment filter is your RO system's first line of defence, trapping visible dirt, dust, rust particles, and sand before water moves further into the purification stages. When this filter gets clogged, it doesn't just reduce water flow — it also forces later-stage filters and the membrane to work harder, shortening their lifespan and reducing overall purification quality. Signs that your sediment filter needs changing include noticeably reduced water pressure at the tap, a visibly discoloured or clogged cartridge, and longer tank refill times. Our technicians carry standard-sized sediment filters compatible with most major brands and can complete a straightforward filter swap quickly, usually within fifteen to twenty minutes. We recommend checking and replacing sediment filters every two to three months in areas with harder or more turbid water, and slightly less frequently in areas with cleaner municipal supply. Keeping this first-stage filter fresh is one of the simplest, most affordable ways to protect the more expensive components of your RO system.
