Waterdrop MNR35 Remineralization Filter Compatible with Undersink RO System

Enjoyed the mineral taste in the water.

Simple to install and the water tastes great. Decent rate of flow.

Worked like a champ. Really good tasting water.

Pros ✅ Improves taste significantly Many users report that RO water tastes "flat" before adding the MNR35 and more like spring water afterward. Reviews consistently mention a noticeable improvement in flavor. ✅ Adds minerals back to RO water The filter is designed to reintroduce minerals such as calcium, magnesium, potassium, and small amounts of sodium after the RO membrane removes most dissolved solids. ✅ Easy installation The 1/4" quick-connect fittings make installation straightforward for most under-sink RO systems. Many reviewers describe it as a simple DIY upgrade. ✅ Long filter life Rated for approximately 9–12 months or about 1,100 gallons of treated water.

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.

everything was good. there was a 3/8" adapter that comes with it that i missed. but it was there.

It does taste more like spring water. Just one issue came up, but figured it out. If you have a system that pumps and has fridge water with a pressure tank,make sure to put the minerizer after the tank, otherwise it will cycle. Another thing, consider a bypass for when you have to change filters so you don't flush minerals down the drain while it flushed the filters.

Installed the new MNR filter with ease and noticed a bit of a restricted water flow. After contacting Waterdrops customer service center the problem was narrowed down to the filter not flushing well enough. Anna L. helped me resolve this problem by having a new one delivered free of charge. Could not be happier with Waterdrops customer service center and their representatives.

Very effective in improving TDS. Improved TDS from 8 to 45. Was delivered ahead of time.

These are made in China and not cheap you can get EU made mineraliser cartridges from AQFILTERS or AIMRO branded crtridges that are far supperior and you can see what's in them (the AIMRO you can't see inside but still EU made and cost around £9)and the build quality is 5 star. Avoid these Who knows what your drinking sort of defeats filtering your water in the first place. Returned for refund be careful what you buy from Amazon when it comes to filters. groaqua.store for AIMRO and aqfilters.square.site for the best mineraliser.

Gute Leistung, aber etwas teuer! Die Filterleistung ist top und das Wasser schmeckt super. Mein einziger Kritikpunkt ist der Preis – dieser könnte gerne etwas günstiger sein. Trotzdem empfehlenswert!

Es de los mejores que se consigue en mexico, aumenta los TDS.

Ce petit filtre de reminéralisation est vraiment top ! Il donne un goût excellent, doux et très agréable à l'eau, je le recommande sans hésiter. De plus, un grand merci au vendeur car tout est arrivé exactement dans les temps, super bien emballé et conforme. Une expérience parfaite pour ce produit !
