Key Benefits
What this system helps you achieve
Reduces staining
Helps control orange and brown iron stains on sinks, toilets, tubs and fixtures.
Protects plumbing
Reduces iron deposition that can contribute to pipe and water-heater problems.
Chemical-free treatment
Adds no treatment chemicals to the water when used within the recommended conditions.
Application Fit
Is it suitable for your site?
Best for
- Well and borewell water with dissolved iron up to 3 ppm
- Whole-house and light-commercial cold-water treatment
- Pentek 10-inch or 20-inch Big Blue housings
- Sites experiencing metallic taste or orange-brown staining
Check before ordering
- Iron must be below 3 ppm and pH above 7.0
- Silica below 100 ppm and manganese below 1 ppm
- No iron bacteria or hydrogen sulphide in the incoming water
- Pre-sediment and post-carbon treatment are recommended for best results

Pentek by Pentair specialty media
RFFE cartridges are part of Pentair’s point-of-entry specialty cartridge range.
Water-chemistry fit is essential
Iron, pH, silica, manganese, iron bacteria and hydrogen sulphide must be checked before selection.
Housing and installation support
Aquainwent can help review compatible Big Blue housing, plumbing and treatment-train requirements.
Iron-load-based replacement
Expected life changes significantly with incoming iron concentration and daily water use.

Why This Model
When RFFE cartridges make sense
A cartridge-based option for dissolved iron in microbiologically safe cold water when the chemistry falls within the stated operating conditions.
1
Targets dissolved iron
Designed for the metallic taste and staining associated with up to 3 ppm dissolved iron.
2
Fits Big Blue housings
Choose RFFE10-BB or RFFE20-BB for the corresponding 10-inch or 20-inch housing.
3
Capacity varies with iron load
Lower incoming iron can provide substantially longer cartridge life than higher iron concentration.
Process
From water check to
From water check to
ongoing support
Test the source water
Measure iron, pH, silica, manganese, iron bacteria and hydrogen sulphide.
Select housing and cartridge
Choose 10-inch or 20-inch Big Blue format based on demand and space.
Build the treatment train
Include recommended sediment pre-treatment and carbon post-treatment.
Monitor and replace
Track staining, taste, flow and expected capacity against iron loading.
Customer Confidence
Built for commercial operations teams
Visible problem reduction
Correct treatment helps reduce metallic taste and orange-brown staining.
Defined chemistry limits
Selection is based on measurable source-water conditions rather than guesswork.
Planned cartridge life
Iron concentration and daily use provide a basis for replacement planning.
RFFE cartridges are designed for dissolved iron under the stated water conditions. Iron bacteria, hydrogen sulphide or heavy sediment require separate treatment and may make this cartridge unsuitable.
The media performance depends on water chemistry. Conditions outside the manufacturer recommendations can shorten cartridge life or reduce effectiveness.
RFFE10-BB fits a compatible 10-inch Big Blue housing. RFFE20-BB fits a compatible 20-inch Big Blue housing.
Life depends strongly on iron concentration and daily usage. The referenced RFFE20-BB data ranges from about 26,000 gallons at 3 ppm iron to 160,000 gallons at 0.5 ppm.
Yes. Pentair recommends pre-sediment and post-carbon treatment for best results, along with confirming that iron bacteria and hydrogen sulphide are absent.
