For Outdoor Freshwater and Travel
Everywhere Filter
Sustainable from start to finish
Every Epic filter is designed with the planet in mind. From recyclable materials and compostable packaging to our filter recycling program and USA-based production, we minimize waste at every step. Each filter keeps over 550 plastic bottles out of landfills—because clean water shouldn’t come at the Earth’s expense.
New Filter Setup
First Use:
Remove filter, straw and package insert from bottle. Set the filter aside for now. Wash the bottle, straw and lid including mouthpiece with a mild detergent and warm water.
Flush Filter:
Remove the filter cartridge from the filter body by turning the straw adapter counter clockwise to the unlocked position. Then remove the filter cartridge by simply pulling the cartridge from the straw adapter. To activate the filter, please soak the filter cartridge in a bowl of filtered water for five minutes. After soaking your filter cartridge, fill up your water bottle (leave some room for the filter), connect the filter to both the straw and the mouthpiece.
Prime Filter:
Take a few quick, strong sips to start the flow of water. Note: first few sips can feel tough to draw in water while the filter becomes hydrated and air is displaced from the filter. Flow rate will improve after continued use.

- JAJohn A.Verified BuyerRated 5 out of 5 stars3 months agoSo far I love this thing.
I confess I drink water from plastic bottles all day long. Since I got this i have not opened a single bottle of water. If there was one thing I'd change, I would like it to fit in a cup holder, in the boat, in the truck, etc. But I still love it and just ordered one for my wife.
- KDKellye D.Verified BuyerRated 5 out of 5 stars6 months agoExcited to now have safe water on the go
I never had an on the go water bottle that filtered my water. I never considered using a public water fountain to refill my water because I feared it was unsafe. Now, I can with this water bottle.
- BKBen K.Verified BuyerRated 5 out of 5 stars9 months agoMilitary Field Tested
This is an exceptional filtered water bottle. I’ve been using it during our field training exercise and it is going through the wringer. Dusty tank trails and falls from military vehicles mean nothing to this excellent container of water. Just wipe it off and keep going. Its true test is the filtering of toxic gunk juice known to the military as “potable water”. Our “purified” military water tastes like public pool water filtered through a Soldier’s fungus impregnated sock but this epic filter makes it so pleasurable to drink I’d almost take it over a Yuengling. People say “I don’t taste anything” to which I say “exactly”. Keep up the good work epic team. Y’all rock. Now if y’all could convince the military to use your systems that would be next level.
- MPMaciej P.Verified BuyerRated 5 out of 5 stars1 year agoExcellent travel bottle
This is excellent travel bottle. I took it with me on vacation to Patagonia. I was refilling it from the tap and from the stream on my hikes. I did not have to buy water at all. I was well hydrated. Water tasted great. Never got sick. Few times I removed the filter and used it for hot beverage. This works like a thermos and kept my tea hot.
- GCGarey C.Verified BuyerRated 5 out of 5 stars1 year agoGood insulation keeps liquids cool
I like this insulated version of the epic system as it keeps my water cool, even in sunlight. It is also large enough that I can add some ice cubes to really ensure I get a nice cooling drink of water in hot weather. The rubber bumper on the bottom of the bottle keeps the container safe in case of drops and the loop on the handle allows one to attach it to backpacks or easily carry the bottle when hiking or just heading to the gym.
It is a larger diameter which means it does not fit most "standard" cup holders. However, I find the larger opening and capacity worth the extra heft and size of the bottle.
FAQs
Please read our FAQs page to find out more.
How do I setup my Epic Bottle
- The filter works best when the media has been pre-saturated with water. Remove the filter cartridge from the filter body by turning counter clockwise the straw adapter to the unlocked position. Then remove the filter cartridge by simply pulling the cartridge from the straw adapter.
- To activate the filter, please soak the filter in a bowl of filtered water for five minutes. If you do not have access to filtered water, please run water over the outside of the filter via your tap. Do this for at least 60 seconds. In absence of both of the options, you can also fill up your water bottle and install the filter the regular way and let the filter sit at the bottom of the bottle for five minutes before drinking. Soaking the filter in a bowl of filtered water is our preferred method.
- Fill up your water bottle (leave some room for the filter), connect the filter to straw like you normally do. Drink normally.

Any tips for me?
- Test your gear before you go! Follow the first use instructions to ensure proper operation of your Epic Water Filters Bottle.
- Keep the lid and mouthpiece away from contaminated water.
- Airplanes & Altitude: Due to the airtight design, pressure may build up during air travel, changes in elevation, or high temperatures. To prevent leaks, slowly twist open the lid, for instance when on an airplane, to release the pressure. Retighten the lid before drinking. You may consider only filling your bottle 3/4 of the way before getting on an airplane.
- If you experience a slow flow rate, blow air through the mouthpiece to remove potential air bubbles and debris from the filter.
- Check the mouthpiece for excessive dust or debris; clean if necessary.
- Note: When the filter cartridge reaches the end of its working life, the Epic Water Filters bottle will no longer filter water. If you are unable to sip water through the straw, it is time to replace the filter cartridge.
