WD-MNR35 Remineralization Water Filter

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!

Obvious Planning, research and execution went into this product. The minerals are well balanced and taste great. My second purchase is usually an indication that im happy with it. Quality, value for money and well deserving of 5 stars, I absolutely recommend.

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.

I added this $29 remineralization filter to my new Waterdrop G3P600 tankless RO system. The taste is excellent, the install took 30 seconds to snap it in place. Also, why buy the upgraded RO system with Alkaline or minerals for $500 more when you could just add this inline and for $29 and achieve the same thing??

The filter does work as intended in introducing minerals back into the RO water. However I feel that it's lifespan is very short. After about 3 months of I'd consider normal water use. It drastically losses it's ability to replenish the water with minerals. At least it does show my RO system works well as without this additional filter. My water taste very "flat", fresh and clean but, akin to distilled almost. Which is good for what you'd expect from the RO system. However for consumption. Drinking pure RO water without re adding essential minerals back into it is not advisable for long-term health. So while this does indeed work, it loses its effectiveness rather quickly. So it is a costly replacement in the long run. I would like for Waterdrop to at least make this filter last longer. A bit larger in size or something. Otherwise. Good item.

Very good quality, I noticed a slight taste difference from straight RO water to remineralize RO water, THE ENGINEERING OF THIS PRODUCT IS EXCELLENT

My whole family loves it. I added the mineral cartridge to it and it makes the best tasting water and ice. It’s pricey but we have loved it. I would highly recommend .

As this is connected in via hose external to the Waterdrop unit, I'd say that even if you bought a Waterdrop unit without this feature (or possibly even a different brand of unit, assuming the same hose size?) this inexpensive filter really enhances the crisp clean taste of the water where I live. I use these filters in a G2 System (https://amzn.to/4eAO0j4) and they work great. They couldn't be any easier to swap out, they for "average/typical" use generally last about one year, and without a doubt I believe they improve the taste of the water considerably. Haven't tried an expensive mlm-model water purifier that had insane costs... these filters and the Waterdrop G2 unit/system are great value for money.
