The Nalgene OG Story

In the 1970s, conservationists began discouraging the disposal of cans and glass bottles by burning and burying them in the wilderness & in recreation areas. Eventually, some of those places responded with regulations and began forbidding such materials. Nalgene products quickly became popular replacements among backpackers for storing consumables; the light, wide-mouthed high-density bottles were more secure than plastic bags and were used for both liquids and solid foods. Originally, wilderness travelers purchased Nalgene products from laboratory-equipment suppliers or gained access to them through their networks, like in their workplaces.

Company lore has it that the Nalgene Company president discovered that his son's Boy Scout troop was using Nalgene laboratory containers for camping. Since then, the company has re-packaged and marketed the items for consumer sales through their line of Nalgene Outdoor Products. In 2018, Epic Water Filters & Nalgene began to discuss a collaboration between the Nalgene wide mouth bottle and the Everyday Filter system from Epic Water Filters (both made in the USA). We could not be happier putting our filter into the OG American made water bottle, the Nalgene 20 oz wide mouth.

Why OG?

"OG" back in the day used to mean Original Gangster although some younger people these days use OG as a quicker way of saying "The Original" - at Epic, we thought, what is more OG than the Nalgene wide mouth bottle? That is why we call it the Epic Nalgene OG. It's the original gangster.

Reusable by Design

At Epic Water Filters, we believe in building products that never become obsolete. Our water bottles with filters are a perfect example. When you invest in the Nalgene OG, you get a modular system designed to grow with your family and perform for years to come. Whether you are trying to remove tap water contaminants or taking your Nalgene OG bottle on your next adventure overseas, the interchangeable filter system has you covered no matter where you find yourself.

Our American-made and American-tested filters outperform well known filtration brands any day of the week. You'll notice some of our biggest competitors do not even publish test results -- that's because their filters only remove bad taste and some chlorine (like that Brita water bottle you've become so skeptical of lately).

What Does This Filter Remove? Everyday Filter Test Results.

Our American-made Everyday Water Bottle Filter are tested against NSF/ANSI Standards 42, 53, 401, & P473 for contaminant reduction (see Everyday Filter Test Results for more)

What are customers saying? From Amazon customer JoshR - 5 Star Review

"I'm an admitted Water bottle addict. I have them in my car, in my pack, in my gym bag. When I saw this bottle, I was really excited because Nalgene was the original bottle before everything had to be double walled and hold ice for 47 days. I felt like they got a bad rap during the whole BPA scare a few years back, so I was excited to get a new Nalgene. Like many people, I was originally skeptical of the need for a filter. I live in a great city with good quality water. And then I filled up my nalgene and drank with the Epic Filter. man o man- it's a whole new world. You really don't realize the chemical tastes you've been conditioned to until you NO LONGER taste them. This is pure water. As far as comparison with other filters, Epic blows the competition out of the water. Look at what they filter out vs Britas- it's no contest. And Epic states that their filters are recyclable, which is fantastic. If you're still buying crazy expensive "spring water", take a look at the Plastic ocean floating in the pacific. Take action. This is a great combo for reducing plastic consumption AND having water that tastes like... well, water. And I live in a city with great water standards. My whole extended family still drinks from well water! Guess what they're getting for Christmas?"
