Equiping for Mexico travel?
Hello Everyone, I am in the planning stages for a fall/winter trip down the West coast of Mexico. This will be my first extended trip in my 5th wheel. Past travel was in a converted Eagle 10 bus. M...

Today it is pretty easy and inexpensive to install your own water purification system with UV to purify drinking water - done properly the finished product is better than most bottled water. The proper filters before and after the UV does the same job as commercial water purification. A $100 UV and a couple filters can be done for under $200. There are also modern reverse osmosis systems that take up little room and don't cost too much - but they do require flushing which requires water so we do not have one in our RV. I think the OP knows this but others reading this thread may not. Many city water supplies now use UV instead of chemicals to purify water.

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses ultraviolet (UV) light at sufficiently short wavelength to kill microorganisms.[1] It is used in a variety of applications, such as food, air, and water purification. UVGI utilizes short-wavelength ultraviolet radiation (UV-C) that is harmful to microorganisms. It is effective in destroying the nucleic acids in these organisms so that their DNA is disrupted by the UV radiation, leaving them unable to perform vital cellular functions.
The wavelength of UV that causes this effect is rare on Earth as the atmosphere blocks it.[2] Using a UVGI device in certain environments like circulating air or water systems creates a deadly effect on micro-organisms such as pathogens, viruses and molds that are in these environments. Coupled with a filtration system, UVGI can remove harmful micro-organisms from these environments.
The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly it was employed to sterilize drinking and waste-water, as the holding facilities were enclosed and could be circulated to ensure a higher exposure to the UV. In recent years UVGI has found renewed application in air sanitation.
