"Give you clean water anywhere, anytime"
—KATADYN Swiss Condi BeFree Portable Water Purifier Reviews
People who enjoy hiking and camping are aware that in the outdoors, they can carry high-energy or high-compression foods that occupy a relatively small volume to save the space and weight of the backpack. However, water cannot do this. The three forms of water, only the liquid state is the form that we can drink directly, but it can not be further compressed to reduce the volume and save space, which are determined by the physical characteristics of water. Then when formulating a 2-3 day trip, when the average temperature is above 20 degrees Celsius on foot, the average water consumption of a person is almost between 4-6L (1L water weight 1kg), if not guaranteed 1000ml per day In the case of water intake, high-intensity trekking is very prone to dehydration, so the problem of water supply is one of the issues that needs to be considered in the process of hiking. Excluding campsites of waterless sources, this article focuses on evaluating the quality of water sources that may be encountered.
brand introduction
I usually do not write brand information based on objective criteria when evaluating, but considering the fact that the water purifier brand is less and more professional, I will make a brief introduction here so that everyone can understand.
The BeFree portable water purifier for this evaluation is part of a European brand KATADYN, Condé. At present, Condit has acquired related companies and sub-brands of KATADYN GROUP as its main products, covering water purifiers, fresh water filters, and industrial water processors. KATADYN outdoor water purifiers originated in 1928 and currently have a global market share of more than 50%.
The author wants to evaluate is the BeFree portable water purifier that has won the ISPO gold prize, we introduce in detail below:
Water purifier appearance and packaging
First of all, thanks to this evaluation opportunity equipped with cool, so that I can understand the product in detail. Water purifier packaging is relatively simple and environmentally friendly packaging, the product itself contains filters, bottles and instructions.

Package side
KATADYN BeFree portable water purifier packaging instructions can filter out 99.9999% of the microorganisms, can clean up to 1000 liters of water life. The whole bottle contains 58 grams of filter and bottle weight. This weight can be regarded as an excellent grade. In the outdoors, any auxiliary equipment (such as stove, camping lamp, etc.) below 100 grams is the first choice for UL lightweight walking camping.

Instructions
Speaking of the instructions, the author has to spit a little, and the thick eight pamphlets cover the eight most commonly used languages ​​of the European Union. It is not inhumanity. But if you really want to make a difference in the Chinese market, I'd like to have a Chinese Simplified Specification, so that consumers can feel warm and caring. If the brand wants to formally enter the Chinese market, the brand's expression information must be localized to be more advantageous to lead the opponent.
Filter and bottle separation
Water Purifier Bottle
The bottle body of the water purifier is soft, and it can be seen that the bottle body has a tick mark and can purify 600 ML of water at a time. The bottle is very soft, easy to fold and store. The material of the bottle is similar to the material of the hump water bag, but it is lighter and thinner.
Water purifier filter
Water purifier filter hollow fiber filter material
It can be seen in the figure that the interior of the filter is closely arranged in the order of the hollow fibers, which effectively removes bacteria and also maintains high water efficiency.
How Filter Materials Work
Sports nozzle
Bottle mouth external dust cover
The sporty siphon nozzle with external dust cover is convenient for drinking, and the efficiency of water filtration is very efficient. 600ML water can be filtered within 10 seconds.
Water filtration test
In order to better demonstrate the effect of the water purifier at the moment, the author selected three different locations of water sources for testing, based on the naked eye to direct the senses based on the division, respectively, turbid water, debris sources, clear water. At the same time, in order to indicate the difference of each water source, it is marked on the test container with various symbols and classified by A and B. A represents the water quality before filtration, and B represents the filtered water quality.
Clear water
Clear water show
The characteristics of the clear water source: The water source is the flowing water source in the mountains between 1500-2000 meters above sea level. The water source before the filtration shows that the water quality is clear without odor, and no visible impurities are visible to the naked eye.
Before filtering
Clear water source water quality before filtration
After filtering
After being filtered by the water purifier, it can be seen that there is no obvious change in the appearance of water quality, and the odor does not change. Since the water quality before filtration is excellent, the bacteria and microbes that are invisible to the naked eye are mainly filtered. After this water source is filtered, the author directly consumes the water. Without any discomfort.

Turbid water source

Characteristics of muddy water source: The water source is the static water source of the pond between 100-200 meters above sea level. The water source before the filtration shows that the water quality is turbid with slight oxidation, there are a lot of tiny microorganisms visible to the naked eye, and the water quality has a slight algae-specific odor.

After being filtered by the water purifier, it can be seen that the appearance of water quality has changed significantly, and the odor has also changed greatly. Because there are many water quality magazines before filtration, the filtered water quality is basically no visible impurities, but the water quality has a very slight turbidity. But it is not obvious. The change in water quality before and after the filtration is very obvious, because the water quality before the water test is too muddy. For the sake of safety, such water sources are recommended to boil and drink better after filtration.
Miscellaneous water sources
Miscellaneous water show
Introduction of the characteristics of water sources for debris: The water source is a water source that contains a large number of aquatic plants at altitudes of 100-200 meters above sea level. The water source before filtration is characterized by clear water quality, heavy smell of aquatic plants, and large amounts of aquatic plant impurities.

After being filtered by the water purifier, it can be seen that the appearance of the water quality is significantly changed. The water before filtration contains a large number of aquatic micro-plants, and the filtered water has no visible impurities, and the plant odor is eliminated. After this kind of water source filtration, I suggest adding disinfection tablets to drink, more secure.
After the above static tests and field filtration tests of three water sources, the author gave the following evaluation results for this water purifier:
advantage
1, lightweight and portable. The weight of 58g is superior in the same type of water purifier, and with the soft bottle marked with a volume scale, the amount of filtered water can be grasped at any time. Soft bottles can also be folded for storage and easy to carry.
2, high service life. The service life of the 1000L water purification capacity is calculated 10 times per year using 10L per year as the standard. It can be used for 10 years. Of course, this is a theoretical value. If you purify low-quality water sources frequently, it is not a problem for five years.
3, excellent quality of purification. From the above tests, it can be seen that even with a water source that is not visible to the naked eye, the visual quality of the purified water is close to that of tap water. This is a very good performance in the water purifiers I have used. .
4, can eliminate odor. Thanks to the excellent hollow fiber filter material, the purified water quality will probably filter out 90% of the odor before filtration, which will make the drinker more comfortable to drink.
5, easy to clean. When you have applied the filter in the field, you can use the filtered water to clean the filter head, dry the bottle and store it. When you come back home, you may wash it once with fresh water and then dry it to make it more convenient for later use and preservation.
Disadvantages and regrets
1. The localization work needs to be improved. As a product that is determined to break into the Asian and Chinese markets, there are no Asian voices and text descriptions. It is a bit difficult to say. Although it is possible for users to read foreign languages, the mother tongue display will make the products more intimate.
2, as a rate of water purifiers, if you can target the extreme environment, with 1-2 pieces of water purification film, you can get more favorable impression, this is personal advice.
to sum up
In summary, the KATADYN Swiss Condi BeFree portable water purifier is a portable, high-quality outdoor water purifier as a whole. If you are a camping walker and focus on lightweight outdoor enthusiasts, then This water purifier is definitely worth your own, it will provide you with more backpack space and better outdoor travel experience in the case of water sources.
