Regarding whether the water in the wild has to be treated before drinking

Everyone has a different idea. Some people think that if the wild is inaccessible, there will be some pollution, and it will be fine if you drink it. In fact, as long as amateur players like us can reach it, what can be truly unpolluted? In fact, even if there is no pollution, it does not mean that there are no viruses, bacteria, or various harmful substances in the water. If conditions permit, whether to deal with it or deal with it. The main method of water treatment is boiling, water purification medicine and filter boiling. This is the most practical and effective method. The disadvantage is that it wastes fuel (of course the stove I have introduced is an exception), and it takes more time. The use of water purification tablets is considered to be a chemical way to purify, most of which use chlorine and iodine. The mainstream in the market is to use iodine. For example, in the picture above, the white bottle is iodine tablets. Keep iodine tablets away from light and moisture. The advantages of using water purification tablets are cheap, convenient and lightweight. It is time-consuming, usually about 20 minutes after adding water purification tablets to drink. The disadvantage is that there is a peculiar smell and color. This can be solved by post-processing. For example, the bottle of yellow pills above is used to deodorize. Or add some Guozhen or something. The second is that there is a major virus that cannot be removed, cryptosporidium, which is probably the most common parasite in water. Third, it is easy to cause allergies, and it will react chemically with certain foods or utensils. In general, water purification tablets still have a large market because of their light weight, cheapness, and small size. It should be noted that you must wait at least 20 minutes in use, and second, do not use it continuously for more than a week. There are actually two categories of purification filters, filters and filter purifiers. The main difference is that the filter removes bacteria and parasites by filtering. In addition to removing bacteria and parasites, the filter purifier can also remove viruses. (Based on the classification of REI) Filter The general filter purifier uses a chemical method to remove the virus on the basis of filtration, such as iodine, so it also has the disadvantages of the previous water purification tablets that chemically purify water. . The claim posted above is the only water purifier that does not use chemical methods to remove viruses. The advantage of using a purification filter device is that you can drink water immediately, almost without waiting, and it is almost the safest way to purify water (if you use a filter purifier). The disadvantage is that the price is expensive, rarely less than 60 dollars, the later cost is also high, and the filter element also needs to spend money. It is large in size and heavy in weight, almost more than 1 lbs. It also needs frequent maintenance during use, which is easy to block. The three methods have their own strengths, and how to choose is their own point of view.
