## Questions & Answers

**Q: Can this filter be used with the woder 10k-genii undersink filtration system or is this for the woder frm fluoride filter?**
A: Only the Woder FRM (http://www.amazon.com/dp/B0126EN5NQ) will filter out Fluoride. The FRM is a dual stage filter. Stage 1 is replacement FRM (http://www.amazon.com/dp/B0144MFK1I). Stage 2 is replacement Gen2 (http://www.amazon.com/dp/B0144MFN92). 2. The replacement FRM does fit the stage 1 system of Gen2 (http://www.amazon.com/dp/B0144MFPOA), however, the taste might be unpleasant and therefore it is recommended to use the replacement FRM only as a 1st stage to replacement Gen2, which also removes all the above but Fluoride.3. If to conclude, if Fluoride is a must to remove, then the Woder FRM (http://www.amazon.com/dp/B0126EN5NQ) is the only solution. Otherwise, the Gen2 (http://www.amazon.com/dp/B0144MFPOA) is recommended to remove Lead, Heavy metals, Chlorine (99%) and other contaminants (99%), odors and bad tastes, Asbestos, Mercury and turbidity, BUT NOT Fluoride...

**Q: What is fluoride removal premium media (95%) (asin b0126en5nq): activated alumina, bone char?**
A: The http://www.amazon.com/dp/B0144MFK1I is a type of activated alumina (NOT a bone char filter), but currently Woder is not revealing the media used.

**Q: Is woder wd-s-8k-r replacement cartridge for woder wd-s-8k-dc water filtration system?**
A: I’m not sure, but it looks like it is. We bought this cartridge as replacement to our Woder 10K-GenII Ultra High Capacity filtration system. When I click on that name in our orders, it now goes to the “wd-s-8k-dc” system.

**Q: Is this the correct replacement filter for the system i purchased in 2018, the  woder wd-s-8k-dc water filtration system?**
A: Yes! The Yes, the WD-S-8K-R is the correct replacement cartridge for the previous Woder 10K-Gen3/GenII models and the new WD-S-8K (WQA Gold Seal Certified cartridge) under sink water filtration system models.
