You may need to make a water filter with your own hands in different situations. Previously, such “home-made products” were used by tourists who needed to purify drinking water.
Today, in domestic conditions, a home-made filter may also be required, for example, if it is necessary to purify water, and the household filter is out of order.
Do not think that a do-it-yourself filter can completely replace home filters geizer.com/catalog/house/. It is worth using such devices only when absolutely necessary, in other cases it is worth installing modern filters on the taps in the house, which not only purify water from debris and dirt, but also affect its chemical composition.
What are homemade filters for? First of all, they help to clean the water from debris, make it drinkable.
At the same time, not all do-it-yourself filters completely purify water, some chemicals still remain in the water. But from suspension and impurities that make water unsuitable for use in food, they release.
Moreover, some filters that you can buy in the store are similar in design to homemade options, such as carbon ones. Consider several options for how to make a water filter with your own hands.
How to make a water filter?
The easiest way to purify water is to pass it through a layer of charcoal. Most of the impurities remain in the filter, and the water is drinkable. Many pitcher filters work on the principle of charcoal cleaning. However, coal cannot rid water of chemical elements.
Another inconvenience is the need to regularly change the layer of coal through which water passes. A filter change is needed every three days, just enough to solve a home water filtration problem.
How to make a carbon filter?
- It is necessary to burn a sufficient amount of birch firewood in a metal container, such as a tank.
- The coals formed after burning, after they cool down, are placed in a funnel.
- The funnel is placed in a container for collecting filtered water, water is poured into the funnel itself from above.
Remember that such a filter cannot be used on an ongoing basis, the coal layer quickly becomes clogged and needs to be changed.
You can improve the carbon filter and make it more efficient by making a multilayer filter. In this case, a layer of sand is added to the coal layer. You will also need a piece of gauze or loose fabric.
- It is necessary to make coal, as in the first case.
- A fabric or gauze is placed in several layers in the neck of the funnel.
- A sufficient layer of charcoal is poured onto the fabric, a layer of river sand is poured onto the coal.
- It is better to pour a layer of gravel on the sand, which, in turn, is covered with a layer of gauze.
The further action of the filter is the same as in the first case. True, here purification will be much more effective. The only negative is the duration of the manufacture of such a filter. The filter media themselves also need to be changed frequently.
The third version of the carbon filter was most common among Soviet tourists and even soldiers during the war. Today, an activated charcoal tablet is in any kit for a foot soldier; it allows you to purify water for drinking in field conditions.
As you may have guessed, you can make such a filter from activated carbon. So, we make a water filter with our own hands.
- A layer of gauze or cloth is placed in a funnel or inverted plastic bottle without a bottom and with a hole in the lid.
- Activated charcoal tablets are poured on it.
- Water is poured onto the coal, which, passing through a layer of agents, is purified.
One standard tablet of activated charcoal is able to purify a liter of water, take this into account when calculating. In any case, there should be several tablets in the filter in order for the purification to be most effective.
Water filter at home
The most elementary household water filter that you can make from improvised materials at home is a filter from cotton wool and paper napkins.
Please note that such filtration can only free water from dirt and debris, but not from chemical impurities, which, in some cases, can be hazardous to health.
- You need to prepare a bottle or funnel, as we did in previous cases.
- The bottle is filled with several layers of cotton wool and paper napkins in random order.
- The dirtier the water, the more filter material must be put into the funnel.
- The filter is ready, you just have to pour water on top and place a container under the funnel to collect clean water.
Such methods of making a household water filter are taught at school. If you know how to purify water for drinking, you will be able to put your knowledge into practice in a difficult situation. In any case, this is only a temporary replacement of the filter; it will be difficult to use such a filter on a permanent basis.
