Clearbrook Refrigerator Filters: RF10-J vs. RF10-S Compatibility Guide
If you've gone looking for "which refrigerator models work with RF10-J" expecting a compatibility list like you'd find for a built-in cartridge filter, here's the good news: that's not how these filters work. RF10-J and RF10-S aren't fridge-specific at all.
Shop both in our Clearbrook water filters collection.
Key Takeaways
- RF10-J and RF10-S are external inline filters that connect to your water line, not internal cartridges tied to a specific fridge brand.
- The real choice between them is connection hardware: RF10-J uses John Guest push-fit fittings, RF10-S uses a compression stainless steel hose.
- Both work with refrigerators that lack built-in filtration; RF10-S is also built for ice machines specifically.
- RF10 filters are rated for 1,000 gallons, per Wild Oak Trail's own listing.
- Check your existing water line's fitting type before ordering, that's what actually determines which one you need.
Why There's No Fridge Compatibility List
Filters like Whirlpool's EDR1RXD1 or GE's XWFE replace a cartridge that clicks into a slot built into the refrigerator itself, so compatibility depends entirely on the fridge's make and model. RF10-J and RF10-S work differently: they're external inline filters that install in the water line before it ever reaches the refrigerator or ice maker. That's why Clearbrook markets them as compatible with refrigerators that don't have built-in filtration, rather than listing specific fridge models. If your fridge takes water from a standard line rather than a dedicated cartridge slot, either RF10 filter can work with it.
RF10-J: John Guest Push-Fit
RF10-J connects using 1/4 inch John Guest fittings, a push-to-connect style that doesn't require compression tools. It's built for refrigerators without built-in filtration, and Clearbrook's own product description notes it installs without professional help.
RF10-S: Compression Stainless Steel Hose
RF10-S uses a 1/4 inch compression stainless steel hose instead. It's built for both refrigerators and ice machines, and the stainless hose is the more durable connection of the two if your setup sees frequent movement or vibration.
How to Actually Choose Between Them
Look at your existing water line connection, or the fitting on whatever filter or cap is currently at the end of it. A push-fit connection points to RF10-J. A compression fitting, or a setup involving an ice machine specifically, points to RF10-S. If you're not sure, a quick look at the fitting itself, or the fitting on your current water line, will tell you more than the fridge's brand name will.
What RF10 Filters Actually Remove
Clearbrook lists lead, select pharmaceuticals, select VOCs, PFOS, PFAS, and chlorine taste and odor among the contaminants RF10 filters address. This is a different contaminant profile than a gravity filter like CB9, since RF10 is built specifically for the cold-water and ice-maker use case rather than general drinking water filtration.

Frequently Asked Questions
Do I need to know my refrigerator's brand or model to pick RF10-J or RF10-S?
No. Unlike filters that replace a fridge's internal cartridge, RF10-J and RF10-S are external inline filters that attach to your water line ahead of the refrigerator or ice maker. Both work with a wide range of refrigerator models. The choice between them comes down to your water line's connection type, not your fridge's brand.
What's the actual difference between RF10-J and RF10-S?
The connection hardware. RF10-J uses 1/4 inch John Guest push-to-connect fittings, built for refrigerators without built-in filtration. RF10-S uses a 1/4 inch compression stainless steel hose, built for both refrigerators and ice machines. Check which fitting your existing water line uses before ordering.
How often do RF10 filters need to be replaced?
1,000 gallons, per Wild Oak Trail's own listed filtration capacity for the RF10 line.
What does an RF10 filter remove?
Clearbrook lists lead, select pharmaceuticals, select VOCs, PFOS, PFAS, and chlorine taste and odor among the contaminants it addresses. This differs from a gravity filter like CB9, which is built around a broader standard contaminant profile rather than the ice-maker and cold-water-line use case RF10 is designed for.
