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

Decent and easy to install

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.

Great quality, highly recommended

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

So we have a Watersrop 600GDP, unfortunately we did not know we needed remineralisation after the RO filter. But glad we know now and have this filter.
