Water filter pitchers have multiple components that accumulate biofilm, algae, and mineral deposits — particularly the lid, the filter reservoir, and the spout. The filter itself cannot be cleaned and must be replaced on schedule; the housing around it, however, requires regular washing.
Disassembly
- Remove the filter and set aside — the filter itself goes into recycling or return programs; it cannot be cleaned
- Disassemble all removable parts: lid, upper reservoir, lower pitcher body, and any seals or gaskets
Washing
- Wash all plastic components in warm (not hot) soapy water using a soft sponge or cloth — avoid abrasive scrubbers that scratch the plastic and create surfaces where bacteria grow
- Use a small bottle brush to reach inside the spout and the lower reservoir
- Pay particular attention to the inside of the lid and the gaskets — these areas accumulate biofilm and are the most common source of a "musty" smell in filtered water
- Rinse thoroughly with clean water
Removing Algae or Mould
- If you see pink, green, or black growth anywhere: soak all components in a solution of 1 tablespoon white vinegar per cup of water for 30 minutes, then scrub and rinse thoroughly
- Store the pitcher in the refrigerator when not in use — cool temperatures slow algae and biofilm growth significantly
- Never leave the pitcher in direct sunlight — UV exposure accelerates algae growth in the water
Filter Replacement Schedule
- Brita standard filters: every 40 gallons or approximately 2 months
- Brita Longlast filters: every 120 gallons or approximately 6 months
- PUR standard filters: approximately every 2 months
- Running water through an overdue filter removes chlorine taste and odour but provides reduced contaminant reduction
