Waterdrop MNR35-2 Remineralization Filter Compatible with RO System

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.

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.

Worked like a champ. Really good tasting water.

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

We purchased a Waterdrop water filtration system with reverse osmosis. I installed a small tank and a re-mineralization filter. Everything works perfectly well on this system and the only real critique that I have with the re-mineralization filter is that if you were looking for a real minerally tasting water, you won’t get it with this. It does everything it says it will do, and it does put minerals back in your water, but it doesn’t change the taste if you’re looking for that minerally taste. I went through two filters within the first week before I realized it and did some research that this particular filter is a mid to low range filter as far as mineralization goes. If you’re looking for that real mineral taste, do some research and buy a higher range filter that puts more mineralization back in your water. They pretty much all use 1/4 inch tubing so as far as installing a different type of filter, you should be OK. Other than that, it was easy to install, and the product says it lasts between six and 12 months or approximately 1100 gallons of water.

Great flavor. Adds about 40ppm TDS to the RO water coming out of my membrane stage. Really helps with that harsh RO taste. It was very easy to hook up and no leaks.

Got tired of the flat taste from my RO unit. Plumbed this in three months ago. Water tastes normal now, not empty. Wish Waterdrop just built this directly into the main system instead of making me mount a separate tube. Worth knowing: You will need a small utility knife to cut your existing RO tubing cleanly before pushing it into the quick-connect ports.

I went through about 7 filters looking for a good mineral / alkaline taste before I found this one! It makes my dead tasting R/O water taste like an expensive bottle of mineral water! So good! I’m glad I found THE filter I’ll be buying again and again!!

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.

La remineralizzazione funziona bene, l’acqua è buonissima, leggera, sapore gradevole (prima bevevo acqua sant’anna/san bernardo)

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.
