Review: Great Product, Easy Install. - Easy install, water tastes better than without. I also received superb support from Waterdrop customer service (Harper)! Waterdrop is a really good company, I've always been impressed by how support their products after purchase. I own three different RO units for various properties and I love them!
Review: Great for coffee - I mainly picked this up for my coffee—everything from espresso and V60 to doing "soup" extractions with the OXO brewer. I looked around at a bunch of options and found that most remineralization filters are either too basic, adding only calcium, or they go way overboard and add too much. This one hits a great middle ground; my final TDS sits right around 30–40, which makes the water taste good without being too heavy. I also added a bypass line so I can still get pure RO water when I want to mix my own specific water recipes from scratch, giving me the best of both worlds. It’s a solid, balanced setup if you want good drinking water.

## Questions & Answers

**Q: What is the source of the calcium used in your filter?  Is it calcite or something else?**
A: This is the answer I received from Waterdrop to a similar question: 
Our MNR filter includes 18 kinds of natural mineral stone materials:
 
Subsurface rocks like Serpentine, sea pumice, Anorthite, Zinc Spinel, Bioclastic limestone, Baimo Dolomite, Magnetite, Wollastonite, Clinoptilolite, Volcanic Stone
 
Shallow underground rock:  like Kunlun Hetian Complex Rock, Marl, Clinoptilolite, Kaolin Ore, Tourmaline
 
Deep underground rock:  like Tianshan Maifan Stone, Potassium Feldspar, Basalt
 
 
The above combination of stone materials is a scientific formula to simulate the environment of the best natural spring water that benefits human health.

**Q: How much will this raise the ph level? At .50gpm(waterprop to system)**
A: They sell an Alkaline filter, that will raise ph more, not this one.. 
All these other answers are wrong, talking about tds. Tds is total dissolved solids,  that is not Physical hardness(ph) tds measures minerals in water. Ph measures the acid level in water. 2 totally different things. This filter is for adding minerals back not really raising ph so you can have Alkaline water.

**Q: Has anyone cut this open after use to see what remains?  i couldn't tell by taste if anything is even happening.  time to buy a tds tester.**
A: TDS testers are a must have and are cheap.

**Q: How do you know that this isnt just adding arsenic and heavy metals back into the water?**
A: Hi,
Thanks for your interest in our MNR filter product.

Please rest assured that only beneficial mineral will be added into the filtered water, and we use natural mineral rocks as source, so there will be no heavy metal releasing into the water, thank you.
