Waterdrop Remineralization Inline Water Filter, 1/4” Quick Connect Post Filter for RO Reverse Osmosis Filter System, Restore Essential Minerals (1)

Amazing difference and the taste is really good can’t stand plastic water bottles and the taste from them now since having this on our ro system

Having spent the last 20 years drinking RO water on my sail boat without remineralisation, I thought I'd treat myself with my new RO unit, recently installed. The difference is night and day! I'd got so used to drinking flat-tasting tea, coffee and straight water, that the introduction of this filter is immediately apparent. Straight water or cordial is especially tasty now. Installation was easy, just insert the 1/4" product water pipe straight into the filter without any additional connections and you're laughing. Now that I know, I will not do without one of these in future.

Decent and easy to install

I use this as the remineralisation filter inline after Reverse Osmosis system from the same manufacturer. It works fine if you are pouring one or two cups of water from the tap after RO. However, the remineralisation cannot keep to the correct level if you are pouring say several litres of RO water. The first half litre of pour gives the correct level of remineralisation but it drops off significantly beyond that amount. When I’m preparing 5 litres of brew water I have to add bicarbonates, magnesium and calcium to make good brew water. In the right proportions this gets the water to the right pH (through the bicarbonates) and the right hardness (through the calcium and magnesium). If you ever need advice on how to do this, just ask ChatGPT and it will tell you the ingredients and percentages.

I don't have a testing device to actually check for quality, but the water does taste different, better.

I’ve fitted this filter in my fridge inline after the normal Samsung filter and what a difference in taste. The water tastes a lot sweeter than normal and very refreshing. According to the description it adds magnesium sodium potassium and calcium so a health benefit too. So much like drinking spring / mineral water so saves pounds in buying such. Highly recommended and a vast improvement on normal filtered water.

Took 10 min to install, instantly noticed a nicer taste in my RO drinking water. Highly recommend

Installed with water drop x8 filter for remineralisation works ok not much difference in taste of 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.

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

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 !

Al top mi ha risolto un problema con un impianto waterprop che funziona molto bene, ma avendo un'acqua in entrata fortemente calcarosa, il reminalizzatore ha risolto alla grande il problema del sapore. Attenzione alla durata che è veramente precisa, non oltre un anno. Per la cronaca gli ultimi vengono forniti anche con l'adattatore da sei a otto millimetri idoneo per gli impianti da settecentonovecento galloni
