APEC Water Systems FILTER-T2Y-ESPH (Replacement Filter Set)

How often should I replace these filters?

The sediment and carbon filters typically last 6-12 months depending on your water quality and daily usage. If you notice reduced flow rate, changes in taste, or it's been over a year, it's time to replace them. The alkaline filter usually lasts the same duration. Heavy sediment loads or high chlorine levels may require more frequent changes.

Will these filters fit my APEC system?

This set is specifically designed for the APEC ROES-PH75 system. The filters are standard 10-inch size and will fit in the designated housings. The alkaline filter includes quick-connect fittings that match the system's connections. If you have a different APEC model, check your system manual to confirm compatibility.

What's the difference between these and cheaper carbon filters?

These use extruded solid carbon blocks rather than loose granular activated carbon (GAC). Solid blocks provide better contaminant removal, don't release carbon particles into your water and last longer. They also resist channelling where water finds easy paths through loose media, ensuring consistent filtration performance throughout their service life.

Do I need any tools to install these filters?

You'll need a filter wrench to remove the old housings, which usually comes with your RO system. The alkaline filter has quick-connect fittings that simply push together. Turn off water supply, release pressure, unscrew housings, replace filters and reassemble. The process typically takes 15-30 minutes with basic DIY skills.

Why does the alkaline filter matter?

Reverse osmosis removes virtually everything from water, including beneficial minerals, leaving it slightly acidic. The calcium carbonate alkaline filter adds minerals back and raises pH to a more neutral level. This improves taste and provides the mineral content many people prefer in their drinking water while maintaining the purity benefits of RO filtration.

How do I know when filters need changing?

Watch for reduced water flow from your RO tap, changes in taste or smell, or simply track the installation date. Most systems benefit from filter changes every 6-12 months. If your water has high sediment or chlorine levels, you may need more frequent changes. Some people set calendar reminders to ensure timely replacement.

Can I use just some of these filters?

While the filters can be replaced individually, it's best practice to change them as a complete set. The stages work together in sequence and replacing all ensures optimal system performance. If one stage is overloaded, it affects downstream filtration. Complete replacement maintains the designed filtration capacity and water quality your system was engineered to deliver.

What contaminants do these filters remove?

The sediment filter removes particles, rust and debris down to 5 microns. The carbon blocks eliminate chlorine, chloramines, taste, odour and many organic compounds. Together they protect the RO membrane and improve water quality. The alkaline stage adds beneficial minerals back. This combination addresses most common water quality issues in municipal supplies.
