And why do people pour cold water into the kettle and not warm water?

An exaggeration is 40 liters of used water per 5 liters of purified water, the current filters do not consume such a large amount of water, but the fact is that the used water is overflow which is drained into the sewage system.

What does not change the fact that after what you see on the pre-filters, replacing them will convince you to the profitability of such an investment. When replacing the pre-filters, they smell like that and there is so much rubbish of various kinds, from typically mechanical impurities to algae, not forgetting what you cannot see, that someone who has such a filter will sooner go to the store for "mineral" water than drink what comes from tap. Mineral in quotation marks because what is sold in stores is water after cleaning through an RO filter and passed through a mineralizer.

By the way, I pour water into the kettle and coffee machine from behind the RO filter, to drink only the water from the mineralizer, behind the filter there is a double tap, one goes mineralized from the other, practically clean. Which is clearly visible in the kettle and coffee machine (no sediment whatsoever). However, drinking RO water alone is not recommended - just as drinking distilled water is not recommended.

Or maybe it is so that in your opinion "pollutants that stink" are really needed by the human body, or at least they do not harm it? Because everything organic decomposes and stinks over time ...

Do you really think that the bottled water in the stores is after some filters or is it taken directly from a hole in the ground?

Spring water is too expensive, taps are cheaper after filtration, so mineral from good sources is healthier, but I doubt that any concern producing bottled water would pay more attention to this ...

Returning to what stinks - no, there should be no microorganisms or algae in the water that decompose and stink in the filters.

Irrelevant. Legionella is killed at temperatures above 40 ° C.

It may sound clichéd but probably YouTube Adbuster or some other native "scientist" made calculations whether it pays to pour hot water into the kettle, as I remember correctly based on the heating water and it turned out that it does not pay off.

Of course it doesn't pay off. District heating or district water is much more expensive than one prepared on site. Exactly like charging an electrician. Charging at home will be 2-3 times cheaper than in the city.

Not true, they die above 70 degrees at 40 feel good and multiply :-)

Especially when there are side installations, end caps, etc., where there is poor circulation or the water is standing

After all, I wrote that above 40 ° C, because the optimum for their development is 38 ° C, above their ability to reproduce decreases. By contrast, the water in the kettle is usually 90-100 ° C, so legionella is not of any use.

I never use warm city water for food.

in single-family houses with hot water heating solar panels, where glycol is used, it is also dangerous. Somewhere, I heard about the coil leakage and glycol getting into the hot water tank.

Because people lead to boiling of glycol in the panels and increasing pressure, because how else would it be closed without a safety valve, it bursts the coils.

A few cascading bugs plus sloppy and problematic.

By replacing the pre-filters with clean ones, you will understand why no water from the mains is safe to drink even after boiling it.

oooo, I change the pre-filters every 2 weeks, I could after a week, it overgrows so quickly. I used to use 100?m, but when I saw what the municipal water was saturated with (I moved in 2012), I started to use it denser, now 20?m and 3 months ago I added another 5?m.

It is de-iron to prevent the formation of deposits.

Currently, propylene glycol is used more and more, the toxicity of which is low, while ethylene glycol has a much greater toxicity than ethanol.

Solar is actually a bit of an extinction technology, although more efficient heating is pv causes a switch to heaters, eliminating several problematic factors related to solar panels.

For me, I replace them every 3 months, but even after this time they do not look as bad as yours. The first one is 30 um and the second one is 1 um.

Kranówa is perfect for that.

From the tap, of course ... Such a life observation came to me ...

The faucet is uneven; I have water from my own intake (pipe stuck in the soil)
and always pour it into the kettle cold water because it makes it fresh.
In addition, brewing coffee from hot or previously cooked water results in a nasty glaze.

My water has a lot of limescale, but I don't do anything about it and I'm behind it; everyone in the area has had the same "beaten" wells for many years, they have been drinking water for generations and do not complain about any problems related to drinking it.
Limescale is deposited on the walls of the kettle and on the heater, so after a short use of the electric kettle and its quick failure (heater shot) - I returned to boiling water in an ordinary kettle, on the gas cooker.
When too much of it accumulates - I clean the kettle with vinegar, which removes the scale.
The first boiling must be longer to precipitate a small layer of limescale on the wall, although the water is slightly cloudy, but the next boiling gives crystalline water.

I do not envy those who, dependent on drinking the city's water, read or listen to what she is like; people who are not immune to suggestions are able to "feel bad" immediately after such suggestions information about water, just as they immediately "feel bad" for information about climate change (although they have felt good so far).

Filters (of any kind) have always been "wonderful" and I know that in some cities the water is really not potable.

This water should not be used for food purposes, every child even knows it. However, I wonder if brushing my teeth and rinsing my mouth with such warm water do I risk any health problems?

Good - it's the same magnesium as in tablets.
Drinking water should not be demineralized because it is harmful to health - water should have limescale - it is an important source of calcium and magnesium (and maybe iron).

That is why there are two taps behind the RO filter, one with demineralized water and the other where the water has passed through the mineralizer.
