Water travel: water filter or tablets, that choosing
No travel, the issue of drinking water can often be difficult. Two types of solutions are then offered: chemical processing, more suited to short stays, and mechanical treatment, more cumbersome, but better over time.

Water travel: tablets and drops for short stays
The tablets and drops are very convenient and extremely easy to use: one tablet or a few drops, a little patience, and you have drinking water.They slip easily into your luggage and you have them with you everywhere. It’s perfect if you travel often during your trip. The major drawback is that you do not have to use it for a long period: prolonged use can indeed cause health risks.
Note: These products are generally used with clear water, without sediment. If water is turbid, it must begin with the filter. Also, remember that pills are very effective against viruses and bacteria, but not against parasites and chemical pollutants.
Mechanical treatment of water for long journeys
Water filters are more suitable for long stays unlike pellets, they are not dangerous to your health if you use long as they do not contain chemical agents. This is the best option to make drinking water if you plan to travel more sedentary. By cons, they are bulkier and more expensive than chemical solutions.
They have the advantage of working well on bacteria and parasites, but are ineffective on viruses. Consider also that their flow is limited, and it will take time to filter the water.
