Reusable by Design

    Appropriately named THE ANSWER, this simple design lid/straw/filter device is a perfect fit for 32 oz and 40 oz Hydro Flask wide mouth water bottles. (More compatible bottles coming soon!) From waterborne pathogens, to heavy metals, fluoride and even trace pharmaceuticals, all are eliminated with our multi-patented filter media. Be confident that the only thing reaching your body is the purest water available. Our filter technology has been tested in 16 different countries, and they promise to remove some of the most contaminated tap water on Earth. Enjoy up to 75 gallons of pure clean water per filter. On average, we recommend replacing it once every few months if being used regularly.

    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 pitcher you've become so skeptical of lately).

    Epic for the Earth


    Goodbye Single use plastics: Each Epic Water Filter eliminates the need for up-to 1500 single use plastic bottles. Enjoy some of the cleanest water on earthing knowing that each sip is contributing to the reduction of single use plastics.

    Partnerships: We are a proud contributor and strategic partner of the Inland Ocean Coalition (IOC) who works to raise awareness of the impact that micro-plastics (single-use bottles and straws) are having on our rivers and oceans. They remind us that you don't have to live by the ocean to care about it. Click here to learn more about them. You can also support IOC by purchasing our OG Special Edition IOC Bottle, proceeds go directly back to them.

    Materials: We opt for materials that are gentle on the environment. Our packaging is 100% compostable, and we have a Filter Recycling Program to help you responsibly dispose of your used filters (and get rewarded for it). To learn how you can recycle your filter, click here.

    We also like to reuse materials in our warehouse whenever we can do so safely so as to minimize our footprint and give a second purpose to materials that would otherwise end up immediately in landfills.

    Giving Back: We believe in supporting others who are doing work that matters. As a 1% for the Planet Member, we commit 1% of our sales each year to give back to environmental organizations that are truly making a difference. We like to engage our local community in making a difference too, so we do monthly creek clean up’s to prevent unwanted waste from making its way from us to the ocean. We love where we live and we like to do what we can to keep it beautiful.

    Recycle for rewards: Can our filters be recycled? Yes, they can! But it's not always easy to find a recycling center that will do so. We use Terra Cycle's Zero Waste Box for Filters so both the filter shell and the contaminants inside can be disposed of responsibly. Want to be rewarded for recycling your filters? Learn more here.

    Best investment I’ve ever made

    I have a block in my head that I can’t drink tap water. I know, how bougie of me. So, I’ve never been able to drink water at work unless I filled up my water bottle at home before getting there. But, this water filter fixed all of that. Now, I’ve been drinking 60+ oz of water every day. This is a game changer. Thank you. My one and only critique is that I wish there was one more slightly larger straw size because this one doesn’t quite reach all the way

    Really good water with one small problem

    I noticed it leaves a little room at the bottom so not all the water is consumed because of this. But besides that, it’s a really solid water filter. I’m glad to be able to have well filtered water with my hydro flask everywhere I go from any sink available.

    Great water bottle filter

    We love the water bottle filter! It is easy to drink out of and fits perfectly into the 32oz and 40oz hydro flasks water bottles. We have used it for only a couple weeks but great piece of mind knowing that when traveling during the holiday time you can still have great clean drinking water!
