Frequently Asked Questions

What is the Omnipure K2540-JJ inline coconut carbon filter and what does it do?

The Omnipure K2540-JJ is a 10-inch inline activated coconut shell carbon filter designed for polishing applications in reverse osmosis systems, refrigerators, ice makers, and drinking water systems. It uses premium coconut shell granular activated carbon (GAC) to reduce chlorine, tastes, odors, and other organic contaminants, delivering cleaner, better-tasting water. Its compact inline design makes it easy to install in tight spaces and connect directly to 1/4" water lines.

What is the micron rating and filtration capacity of the Omnipure K2540-JJ?

The Omnipure K2540-JJ features a nominal 20-micron rating, making it ideal as a polishing filter rather than a sediment filter. It has a rated capacity of approximately 1,500 gallons or a 12-month service life, whichever comes first. The maximum flow rate is 0.75 GPM, with an operating pressure range of 20–100 psi and a temperature range of 40–100°F.

What are the fitting size and connection type on the K2540-JJ?

The Omnipure K2540-JJ is equipped with 1/4" female NPT (FNPT) threaded connections (denoted by the "JJ" in the model number) on both ends. This allows easy installation with standard 1/4" fittings, including John Guest quick-connect push-fit adapters or compression fittings. The filter measures approximately 10 inches in length by 2 inches in diameter, making it compatible with most under-sink RO systems and refrigerator water lines.

Is the Omnipure K2540-JJ NSF certified?

The Omnipure K2540-JJ is manufactured in a facility that follows NSF/ANSI Standard 42 guidelines for material safety and chlorine/taste/odor reduction. The coconut shell activated carbon media used in this filter is FDA-compliant and tested to meet NSF standards for drinking water components, ensuring the filter housing and media are safe for potable water applications.

How often should I replace the Omnipure K2540-JJ filter?

Omnipure recommends replacing the K2540-JJ every 12 months or after filtering approximately 1,500 gallons of water, whichever comes first. If you notice reduced flow, returning tastes or odors, or if the filter is used in an RO system as a post-filter, replacement may be needed sooner. Since the K2540-JJ is a sealed, disposable inline cartridge, the entire unit is replaced—there are no internal media changes required.
