water
Everyone has different ideas about whether the water in the wild should be treated before drinking. Some people think that people in the wild are rarely seen, so there will be no pollution. It's OK to drink. In fact, even if there is no pollution, it does not mean that there is no virus, bacteria, or various harmful substances in the water. If conditions permit, it is better to handle it. Water treatment methods mainly include boiling, water purification chemicals and filters， sports fitness .
boil
This is the most practical and effective means. The disadvantage is that it wastes fuel (except for the zip stove I have introduced), and it also consumes time.
Water purifying tablet
The use of water purification tablets is regarded as chemical purification, and chlorine and iodine are mostly used. The mainstream in the market is to use iodine. For example, iodine tablets should be kept away from light and moisture. The advantages of water purification tablets are cheap, convenient and light. It takes a lot of time. It takes about 20 minutes to drink the water purifying tablets. One disadvantage is that it has peculiar smell and color. This can be solved through post-processing. For example, the bottle of yellow pills above is used for deodorization. Or add some fruit. Second, there is a major virus that cannot be removed, cryptosporium, which is probably the most common parasite in water. Third, it is easy to cause allergy and chemical reaction with some food or appliances. In general, water purification tablets still have a large market because of their lightness, cheapness and small size. In terms of use, it is important to wait at least 20 minutes. Second, do not use it continuously for more than a week.
Purification filter
There are actually two categories, filter and filter purifier. The main difference is that the filter removes bacteria and parasites by filtering. The filter purifier can remove bacteria and parasites as well as viruses. (Based on the REI classification) The advantage of using the purification filter device is that you can drink water immediately without waiting, and it is almost the safest way to purify water (if you use the filter purifier). The disadvantage is that the price is expensive. Few of them are less than $60. The later cost is also high. The filter element also costs money. It is large in size and weight, almost more than 1 lbs. Frequent maintenance is also required during use, which is easy to block.
