The quality of water which reaches our crane not always answers standard indicators. That its use has not led to problems with health, it is necessary to use only purified water. It is possible to choose the household filter if to know about their modifications and ways of cleaning.
Instruction
1. Learn type zagryazneniyapered acquisition of the filter make the analysis of water which you should purify. Many unnecessary particles are part of water: sand, rust, organochlorine compounds, fluorides, industrial pollutions and many other things. Depending on the nature of the main impurity make choice among set of modifications of filters: for hard water, for soft water, bactericidal, for removal of chlorine. For example, the filter for hard water softens it, removing excess salts of calcium and magnesium. If water has metal smack, the water filter absorbing iron and manganese will approach. And full removal of mechanical impurity requires the equipment detaining foreign debris.
2. Choose type you filtraopredelit extent of filtration which is necessary for you. By means of filters it is possible to remove one-two impurity or to receive absolutely clear water. Two types of filters are widespread: periodic and flowing action. To remove separate particles, choose filters of periodic action. They are easy-to-work: in them water passes through the cleaning layers of the cartridge and gathers in receiving capacity - jug. Considering that the average physiological norm of water for 1 person is 3 l, count its approximate consumption. Not to lack liquid, choose the filter capable to clean 2-3 times more. If you have small family, pick up jug capacity to 2 l – it will be enough for pure numerous preparation for 1 or 2 people.
3. Choose class of filters of dependence on how flowing water arrives for cleaning, filters are divided into three classes: are got on the crane, are connected to the crane during filtration and are built in water supply. The first – act as tanks – jugs. The second – are connected to the crane by flexible hose only for the period of filtration, and then act. If you are interested in high-quality cleaning, stop the attention on stationary flowing filters - they are installed directly in water supply. Here water undergoes multistage cleaning: mechanical, removal of chloric connections and harmful impurity, mitigation and disinfecting. Thanks to it it becomes suitable for drink and cooking.
