Here we present the most effective methods clean and pure water filtration, but to find the right one. it is best to ask your water company for chemical and bacteriological analysis of the water it supplies (it has a legal obligation to do so if requested).
What Type Of Water Filter Do I Need!
1. Chlorine Evaporation
The most comfortable and most economical method of removing chlorine is rest. We can fill a container and wait before consuming it for the chlorine to evaporate. The more hours, the better, but you have to consume that water preferably within 24 hours to avoid any kind of contamination.
Obviously, this way we don’t filter the rest of pollutants and impurities from the water, but at least we get rid of the chlorine.
2. Active Carbon
This system is associated with the famous filter jugs , but it is also presented as filters that are installed at the outlet of the tap or under the sink .
They contain active carbon and are economical (a good carbon filter does not cost more than $ 160, and there are from $ 25). In addition, they are very effective in improving the smell and taste of water. Since they eliminate some volatile organic compounds such as chlorine.
Yes, and stein away from the high filtering capacity of other methods. Such as osmosis and lose effectiveness as the filters become saturated.
The reverse osmosis filter works bypassing the water from the network through a semipermeable membrane with strong pressures. This process allows particles of up to 0.001 microns to be removed (human hair measures between 60 and 80 microns).
It is the most effective and recommended system to eliminate chemical contaminants present in the water and thus obtain practically pure water. Its technology has significantly improved in recent years to achieve a 95-98% degree of purification of all substances dissolved in water.
The list of substances that it filters is very long: arsenic, boron, cadmium, copper, calcium, chromium, silver, manganese, mercury, sulfates, chlorides, sodium, selenium, zinc, strontium 90, radius 226 and 228, tannin, micro-algae, bacteria, fungi, mold, pesticides, medications.
There are them with the pump or without pump according to the pressure available in the house. There are with or without deposit. And those with a deposit can have filters and deposit separately or together in a kind of “computer tower”. There are also “desktop” models for the kitchen counter top. They do not need auxiliary tap since they incorporate one in the same body of the equipment.
The economic investment is much higher than that of the active carbon: quality teams are around 1,000 euros. And you have to change the filters every year and every few years, the membrane.
Its Drawbacks Are That:
To obtain 1 liter of pure water, you have to filter another 3 liters (or more depending on the device) that go down the drain. If you want to take advantage of this “rejection water” to clean or water, you have to divert the osmosis drain tube. But if we compare it with the daily use of sanitary water (200-250 liters of water per day and person), the 10 or 12 liters of osmosis no longer seem so wasteful.
The resulting water is very “clean.” But in any osmosis equipment, you can add the filters you want to remineralize, ionize it, etc.
4. Water Softener
Declassification with exchange resins is considered adequate to remove lime in hard water regions. Among its advantages:
- Extends the life of appliances and clothes, takes care of the skin and hair.
- It decreases the energy consumption associated with heating domestic water and heating.
- Avoid the cumbersome white spots typical of lime in faucets, shower screens, glasses, etc.
- It allows saving on detergents (lime prevents soap from acting).
Now, it also has its drawbacks. All the water in the house passes through these devices. So they are usually installed near the entrance. To collect the lime that the water softener is retaining and pour it down the drain, salt is used. From the point of view of the environment, it is highly advisable, but the impact of having water with lime is greater.
It also slightly increases the sodium content of water. Which is in advisable in certain pathologies such as hypertension.
- There are anti fouling systems, also called softeners. Which do not remove lime but prevent it from sticking to the internal surfaces of the pipes.
- The soft water without lime is suitable for skin care and hair. But does not eliminate other impurities from the water as osmosis.
The classics do not filter the water but instead evaporate it and then condense it. They get very pure water and 99% free of pollutants but very unbalanced according to the detractors of this system, who consider it suitable for cleaning or specific medicinal uses, such as therapeutic fasts, but not for daily family consumption.
It is a slow system that requires more energy consumption than osmosis.
Conclusion Clean And Pure Water Filtration System
When choosing one of these systems for clean and pure water filtration, you have to look for serious professionals. The investment can be remarkable but worth it for health, comfort and saving bottles, which in turn implies caring for the planet for our children.
