In the UK, most domestic and commercial water filters should be replaced every 6 to 12 months, depending on the type of filter, water quality, and usage levels. Here's a quick breakdown:
• Sediment filters (used in pre-treatment): Every 6 months or sooner if water flow drops noticeably.
• Carbon filters (for taste, odour, chlorine): Every 6 to 12 months.
• Reverse osmosis filters: Prefilters every 6–12 months, membrane every 2–3 years.
• UV lamps: Annually (bulb may still light after a year but won't provide effective disinfection)
• Limescale filters: Cartridges usually last 6–12 months, depending on hardness and flow.
If you're dealing with high sediment levels, hard water, or heavy usage (like in a commercial setting), you may need to replace filters more frequently. Always follow the manufacturer’s guidance, and if in doubt, we’re happy to advise based on your system and setup.
