APEC Reverse Osmosis Filter Replacement Guide
Why Regular Filter Replacement Matters
Your APEC reverse osmosis system is like a car; regular oil changes and maintenance is required from time to time. The same idea applies to your water filters. Over time, they collect sediment, chlorine, and other contaminants. If they’re not replaced, your system can’t do its job, and the water won’t taste as fresh and clean. Regularly replacing your Water Filters keeps your APEC water filter system producing healthy and clean water. And, Using genuine APEC water filter parts means everything fits perfectly and works the way it should.

Sediment & carbon filters: Every 6–12 months
RO membrane: Every 3–5 years
Advanced Coconut Shell Refining Carbon (TCR): Every 3–5 years

Troubleshooting Common Issues
Even with new filters, sometimes things don’t go as smoothly as planned. Here are the most common hiccups (and quick fixes):
- Low water flow: Often means it’s time for a new RO membrane replacement.
- System keeps draining: Could be a worn auto shut-off valve or you might benefit from a permeate pump to balance water pressure.
- Bad taste or smell: Usually solved by flushing the system longer or replacing the carbon filter.
- Leaking faucet or fittings: Check the O-rings and connections
- Gurgling noises: A little is normal, but loud or ongoing gurgling can mean air in the system or an installation issue.
