📌 Note: Filter lifespan depends on various factors such as usage conditions, maintenance, cleaning frequency, water consumption, and raw water quality.
💡 Tip: Regularly replace the PP filter (every ~3 months) to prevent clogging of subsequent filters, extending their lifespan. The PP filter is also the most cost-effective to replace.
