Proper Maintenance of Household Water Filters: A Complete Seasonal Guide
Essential maintenance tips and replacement timelines for pre-filters, carbon blocks, and RO membranes during the monsoon season.

During and immediately after the monsoon season, water turbidity in Nepal spikes significantly due to silt and surface runoff.

To ensure your home filtration system operates at peak efficiency, follow these guidelines:

1
Pre-filter Inspection Check the spun PP sediment cartridge every 30 to 45 days during heavy rain seasons. Replace when discoloration turns dark brown.
2
Activated Carbon Flushing Carbon filters remove chlorine, volatile organic compounds, and unpleasant odors. Replace every 6 to 9 months.
3
RO Membrane Care Monitor TDS (Total Dissolved Solids) levels regularly. Ensure pre-filters are replaced on time to prevent membrane scaling.
4
UV Lamp Life UV sterilizers kill harmful bacteria and viruses. Replace UV lamps annually to maintain effective germicidal dosage.

Always look for certified WAFEAN member logos when purchasing genuine replacement parts.
