Maintenance Q01 How often should I replace the cartridges and where do I purchase them?
Last Updated 23 days ago
All iSpring RO systems are designed with ease of use and low maintenance in mind. The frequency of replacing the cartridges depends on the source water quality and water usage. Normally, the first 3 pre-filters (F3) and the sixth stage (if any) alkaline filter (FA15) or DI filter (FD15) need to be replaced every 6-12 months, or sooner if water flow becomes slow. The fourth stage RO membrane (MC1) needs to be replaced every 2-3 years or sooner if the TDS level starts increasing. The stage 5 carbon block filter (FT15) and stage 7 (if any) UV lamp need to be replaced every 12 months. You may search the model number on our website to purchase them.
