What is a micron and why should you care when filtering water?
On long backcountry treks, you’ll want a hydration plan other than to lug around multiple gallons of water. When you encounter a freshwater source, such as a river or a lake, you have a few options to make that water potable: boil, filter or treat with tablets.
You’ll want to treat the water, no matter how clean it looks. It could have bacteria, viruses and parasites that can make you sick. Boiling the water for a full minute at a rolling boil should kill most of those nasty organisms. At elevations of 6,500 feet and above, boil for three minutes.
If you’re on the go, though, you can drop water treatment tablets into your bottle and wait a half-hour for clean water. Or you could filter your H2O — but what kind of filter should you use? There are straws, pumps, bags and bottles. Some contain chemicals or carbon to further treat the water. Many companies tout how small their filter pores are, using a measurement called microns. So, what is a micron?
Micron is short for micrometer, which is one-millionth of a meter. For those of us not too familiar with the metric system, especially the minuscule end of it, a micron equals .00003937 inches.

Outdoor Life: Do You Really Need a Water Filter for Backpacking and Mountain Hunting?
Fresh drinking water is essential. This water filtration system ensures you will never run out as long as there is a nearby natural water source. It can filter out bacteria, protozoa and microplastics.
Faster and more efficient than pumping or waiting for chemical treatments, the Sawyer Squeeze System offers on-the-go hydration at a good flow. This product is long-lasting, affordable, reliable, cleanable, and very user-friendly.
But Sawyer was way ahead of me — 15 years ahead, to be precise. In 2008, the brand started its Clean Water for All initiative, which provides Sawyer filters to developing countries around the world. And the company spends 90% of its profits funding it.
