The outdoor water purifier is a drinking water protection device that is convenient to carry when carrying out outdoor activities. When it is used, it does not need to be installed on a faucet, and it does not require tap water pressure. It only requires manpower to immediately purify outdoor natural rainwater, streams, rivers, lakes and other natural water into sterile, non-suspensive contaminants and other hazardous substances that can be used directly for drinking.

Water purifier selection principle:
The quality of outdoor water purifiers is very important. The quality of outdoor water purifiers is not good. So, how do you choose a quality outdoor water purifier?
1. The materials used must be safe. Domestic and foreign water purifier materials have clear requirements, through the material security immersion test to prove that long-term exposure to water will not release harmful substances into the water, the famous foreign testing agencies are the United States WQA Water Quality Association, Germany TUV SUD, domestic There are provincial disease prevention and control centers, and material security is the most basic requirement for the quality assurance of outdoor water purifiers. If the foundations are not played well, then nothing else can be said.
2. Ensure a certain filtering effect. The effect is good or not requires the professional inspection report of authoritative and professional inspection agencies. It is not enough to look at the propaganda of the manufacturer. It must be tested or certified by an authoritative third party. It is worth noting that the general outdoor water purifier filter bacteria can only reach 99.99%, and only a few brands of products have a bacterial filtration rate of 99.9999%. The filtering effect is the core of outdoor water purifiers. Only a good filtering effect can guarantee the safety and health of the water.
3. The manufacturer's quality management system must be improved. The popular saying is to have quality control and control of the products from the raw materials to the factory. The formal enterprises must pass the ISO9001 international quality management system certification. Among them, Germany's TUV is the most rigorous and relatively authoritative. General formal and professional companies will pass the ISO9001 international quality system certification, because the manufacturer's quality management system is perfect, marking a company's responsibility and quality of consumer attitudes.
