Woder WD-HMG4-DC Water Filter.
Woder WD-HMG4-JG Water Filter.

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.
Heavy Metal & Lead Removal Replacement Cartridge (WD-HMG4-REP)
For existing owners of our heavy-metal combo systems, the WD-HMG4-REP is the cartridge that keeps that protection going. It’s a water filter cartridge replacement built for our WD-HMG4-DC and WD-HMG4-JG products, combining the same Gen4 Advanced media with dedicated heavy-metal and lead removal, packaged as replacement water cartridges you can order without buying a whole new housing.
What This Cartridge Removes
This cartridge removes the same things your original system did: standard Gen4 contaminants like chlorine and lead, plus the added heavy-metal media targeting arsenic and elevated lead specifically. It’s one of our more specialized replacement cartridges for water filters, functioning as a genuine heavy metals removal filter rather than a standard cartridge, since the media combination isn’t shared with our standard filters. On certification, it’s worth staying precise: the base Gen4 stage is WQA Gold Seal certified, while the added heavy-metal media is CLB Labs tested, a distinction we keep consistent across every heavy metals removal replacement cartridge we sell.
Knowing when it’s time for replacing water filter cartridge media like this comes down to the usual cues: a drop in flow rate, or simply hitting the cartridge’s expected lifespan as listed on the product page. Because this cartridge is doing more work than a standard filter, tracking your install date is especially worthwhile here, since waiting for a symptom means you may have already gone a while without full heavy-metal protection. Ordering water filter cartridge replacements on a set schedule rather than reactively is the more reliable approach for this specific product. This cartridge is designed and packaged in the USA.
When to Replace It
Installing the new cartridge follows your original housing type: DC systems unscrew for a straightforward swap, while JG systems use a push-to-connect cartridge change. Either way, our install guides cover the exact steps, and most heavy metals removal cartridge swaps take just a few minutes.
Frequently Asked Questions
Which Woder systems is this replacement cartridge compatible with?
It’s built for our WD-HMG4-DC (under-sink) and WD-HMG4-JG (inline) heavy-metal combo filters, matching the same Gen4 plus heavy-metal media combination in both.
How often should I replace this cartridge?
Watch for a drop in flow rate, and check the expected lifespan listed on the product page. Given the specialized media, replacing on a set schedule is more reliable than waiting for a symptom to show up.
Is this cartridge WQA certified?
The base Gen4 Advanced media is WQA Gold Seal certified. The added heavy-metal removal media is CLB Labs tested rather than WQA certified, and we keep that distinction accurate across all our heavy-metal products.
