Water bottles with filters
There is no doubt that trekking through Nepal will connect you with the beauty of the Himalayas and provide amazing views of snow-capped peaks, clear lakes, and a connection with a rich and ancient culture, but like any outdoor activity, there are some risks.
Nepal’s rivers may look clean and pristine but just like in the US and other parts of the world invisible parasites are a danger. What this means for you is that you’ll either need to choose between purchasing water, which is expensive and environmentally unfriendly because it is sold in disposable plastic water bottles, or investing in some type of water filter or purifier on your trip. We believe a water filter or purifier is better for your wallet and the environment.
The main difference between a water filter and a water purifier is that a water purifier uses a chemical reaction (usually iodine) or ultraviolet light to eliminate viruses from water, whereas a filter eliminates dangerous bacteria, but not viruses.
Another difference is that purified water has a chemical taste and you may have to wait 30-60 minutes to consume it, while filtered water does not. Both methods eliminate Giardia, which the Center for Disease Control (CDC) recognizes as one of the most common causes of waterborne illness.
The germ is found in every part of the United States and the world. The Centers for Disease Control recommends using a filtration system that meets the industrial standard of 0.2 microns, which filters out most harmful bacteria. The CDC’s website provides information about the most common parasites, bacteria, and viruses found in water and lists compelling reasons for international travelers to invest in a water filtration or purification system.

There are many companies that produce water filters and purification systems and each has there own advantages and disadvantages, you should make your choice based on your own preference for weight, money, and other needs.

There are also various methods for filtering and purifying water, ranging from hand pumps to gravity filters. Gravity filters filter a larger amount of water, but take longer than hand pumps and may require a group effort to set up.

Investing in a good water filtration or purification system will ensure that you enjoy Nepal’s natural and cultural wonders in a healthy and environmentally friendly way.
