Water is essential for biological life but also the biggest ripoff in an airport. Not to mention it’s usually sold in plastic containers so a filtered water bottle can not only save you money but creates less waste as well. There are a variety of options for travelers making a straightforward accessory a potentially complicated decision.
To make it easy, there are basically two types of filtered water bottles to be aware of and these are the best filtered water bottles of each to travel with.
In Short, Two Types
Basically there are two primary types of filtered water bottle – those designed for hikers and those for tap water. For most travelers, the latter is what you’re looking for. The majority of filtered water bottles are made to purify tap water, which is useful at airports, new cities, or at the gym. Essentially, they improve the taste of and eliminate the most common bacteria (down to 0.01 micron) you might come across in already treated water.
The SurviMate won’t filter heavy metals or viruses meaning you can’t just fill it up from a lake and chug. But it can help you get cleaner water from drinking fountains at airports plus has replaceable filters.
Straight Outta Nature
On the other hand if you’ll be hiking or know you won’t have access to treated water, the GRAYL filters out nearly all bacteria, viruses, and heavy metals. GRAYL uses a manual pump system that can remove larger sediments as well. It might be a bit overkill depending on where you’ll be traveling but for the best portable water protection, the GRAYL is worth the investment.
More Options To Choose From
Of all the filtered water bottles I tested, the primary differences between the types were small. Tap water filters generally have a .01 micron limit and many SurviMate knockoffs don’t have replaceable filters. (Many claim the filters are “coming soon” but SurviMate’s been around a while and have filters that last a year under regular use of 4 liters/1 gallon per day.)
As for the wilderness water filters, the prices generally go up based on the amount of water being filtered but for backpackers a typical water bottle size is ideal. Other options like UV pens I’ve found aren’t as reliable since they can’t remove large particles or heavy metals from water like the GRAYL. You can check this map to see where you can and can’t drink the local water, filter tap as you go, or GRAYL for the great outdoors.
