Franklin FWPC 10" x 2.5" Polypropylene & Coconut Carbon Filter Cartridge – 5 Micron RO Prefilter for Sediment & Chlorine Reduction

Dual-Media 5-Micron FWPC Filter Cartridge for RO Prefiltration & Point-of-Use Water Treatment

The Franklin FWPC Filter Cartridge is a high-performance dual-media filter designed for reverse osmosis (RO) prefiltration, post-treatment polishing, and general point-of-use drinking water applications. Combining a graded-density polypropylene sediment filter with coconut carbon GAC, the FWPC provides two stages of protection in a single cartridge—capturing fine particulate matter while reducing chlorine, taste, and odor.

Engineered with a complex density gradient, the polypropylene layer maximizes dirt-holding capacity and resists bacterial growth without binders or additives. The integrated coconut shell carbon media removes chlorine and trihalomethanes (THMs), helping protect RO membranes and improving the taste and clarity of drinking water.

Designed to fit standard 10" x 2.5" filter housings (standard or slimline), this cartridge offers a reliable, economical upgrade for residential RO systems, potable water filtration, and commercial beverage or process water applications.

Specifications

Frequently Asked Questions (FAQs)

What does the FWPC filter remove?

It reduces:

• Sediment, rust, and particulates (5-micron)

• Chlorine

• Taste and odor compounds

• THMs
  It also protects RO membranes from chlorine degradation.

Can this filter be used as both a prefilter and postfilter?

Yes. The FWPC is suitable for:

• RO prefiltration (sediment + chlorine removal)

• RO post-filtration (taste and odor polishing)

Will this cartridge fit my RO system?

If your system uses a 10" x 2.5" standard or slimline housing, the FWPC will fit.

Is the sediment media safe and bacteria-resistant?

Yes. It is made from #1 grade virgin polypropylene, which is:

• Cellulose-free

• Bacteria-resistant

• Free of binders and additives

Does the carbon media improve taste?

Yes. Coconut shell carbon is highly effective at reducing:

• Chlorine

• Taste & odor

• Organic contaminants

How often should the filter be replaced?

Typical replacement is every 6–12 months, depending on:

• Chlorine levels

• Sediment load

• Water usage

• RO membrane protection requirements

Is the filter safe for potable water?

Yes. All materials of construction are compatible with potable and process water applications.

Can it handle hot water?

The maximum temperature is 40°C / 105°F—do not use with hot water lines.

Does this filter remove dissolved minerals or soften water?

No. It removes sediment and chlorine but does not soften or demineralize water.
