Selective Filtration™
Our proprietary Selective Filtration™ technology removes 99.9% of contaminants while leaving in all essential minerals. Reverse Osmosis (RO) filters also remove 99.9% of contaminants, however, RO also remove ALL the minerals found in tap water – including minerals your body needs. RO systems can waste thousands of gallons of water annually while flushing out contaminants down the drain.
20-Micron Sediment Replacement Cartridge (WD-20M-REP)
If your pre-filter is due for a swap, the WD-20M-REP is the sediment filter cartridge built to match. This is a single-part order for existing owners of our pre-filter products, whether inline or under-sink, and it’s sized to drop right into your current housing without needing a new full system. It’s the same 20-micron media as the original sediment water filter cartridge you started with, just fresh, so there’s no change in what it catches or how it performs once installed.
What It Removes
What this part removes hasn’t changed from the original: it’s 20-micron mechanical filtration, catching dirt, sand, and rust with no chemical media involved. A sediment cartridge filter like this one won’t reduce chlorine or lead, that’s not its job, but it does keep particulate out of your fixtures and protects any downstream Gen4 stage from abrasive buildup, which is part of what extends downstream filter lifespan across your whole setup. Every water sediment filter cartridge we sell for this line uses the same media spec, so performance stays consistent replacement after replacement, regardless of how many times you’ve swapped it before.
When to Replace
Knowing when to swap comes down to a couple of clear signals: a drop in flow rate is usually the first thing people notice, and it means the part has trapped enough buildup that supply isn’t moving through as freely as it should. Households on well water or older plumbing will typically need to replace a cartridge sediment filter more often than those on cleaner municipal supply, simply because there’s more particulate coming through in the first place. Tracking the part’s expected cartridge lifespan alongside those flow-rate cues is the most reliable way to stay ahead of a worn-out part rather than waiting for performance to drop off noticeably first.
How to Replace It
Swapping it in is quick regardless of housing type. Our install guides walk through the specific steps for both inline (push-to-connect) and under-sink (unscrew) versions, so you’re not guessing at the process even if it’s your first time replacing this particular part. Ordering a compatible replacement cartridge going forward is just a matter of bookmarking this product page for the next time it’s due. This part is designed and packaged in the USA.
Frequently Asked Questions
Which Woder systems is this replacement cartridge compatible with?
It’s built to fit our pre-filter products across both the inline (JG) and under-sink (DC) product lines, matching the original 20-micron media spec.
How often should this cartridge be replaced?
That depends on how much your water carries through. A noticeable drop in flow rate is the clearest sign it’s time, and households on well water or older plumbing typically need more frequent swaps.
Does this cartridge remove anything besides sediment?
No, this is mechanical filtration only, built to trap dirt, sand, and rust. It doesn’t reduce chlorine, lead, or other chemical contaminants.
