bonsoir,
I would like if you allow to put things a little into filtration .....
first thing to consider: what is the quality of
your water (from the tap) ?? ..... (it is absolutely not equivalent for all !!)
second thing: what is for you the
priority reason filtration ?? => either have a little better for cheap (= taste improvement with economic reluctance) ...> or desire for healthy and harmless water (= qualitative approach)
third thing: what is the budget that you give to this choice ??
>> because I sincerely believe that this subject of the filtration of drinking water cannot be both really qualitative
et econological ....
So if you want to make a coherent choice, you must first answer these three questions, and then define the choice of the filtration process based on these answers ....
but ... except in some rare cases, you cannot hope to have the best for a handful of € .....
but beware too, it is dangerous at the moment to say that
there is no danger of consuming tap water regularly since it is recognized as potable !! , because "drinkable" is an official "value" but does not represent a harmless quality !!! .....
but also pay attention to the choice (qualitative once again) of the filtration device, because if the "reverse osmosis device" represents the best level of filtration, a 300 € reverse osmosis device will probably be Chinese equipment which will not have a guarantee of reliability / durability necessary for its function ......
but also beware of "miracle products" which (supposedly) eliminates all that is bad and keeps you all that is good, and all for 25.95 € ......
but be careful also to believe that the Brita or other guarantees you quality water free of any pollutant ......
>>> this subject is very delicate, very complex, difficult to generalize due to the very different characteristics of water from one region to another, a sensitive subject and increasingly "juicy" alas (therefore vigilance !!) ......
but for those who accept the choice of
quality for health .... there is a certain obvious cost, but this cost is more to be considered as an "investment in good health" than as an ancillary technical expense .. !!!
obviously remains to make a good choice, and not to be fooled in the game of bizness ....
I do not find it judicious, for example. to invest € 2700 in a water refiner (= softener), even if you have hard water .....
for having studied and still studying the thing, personally I think that the most "econological" remains the filter (for sink) type "micro" or "ultra" filtration,
for purely qualitative research (health), it is osmosis + dynamization ....
for general ecology and well-being: this would be the full use of rainwater (including drinking water)!
here is a point of view which is mine, but not only ....
everyone can judge ... without judgments .....
friendly ....

well hello to you !! ...
