Cowa removes about over 15X times the number of contaminants of Brita, providing high-quality, naturally filtered water wherever you live in the world.
Cowa is designed to be the simplest and most affordable water filter that anyone can use. Whether you live in the U.S., Kenya, or pretty much anywhere, Cowa is meant to remove the worries you may have about the water you drink, without having to dish out hundreds of dollars.
Perfect for everyday use or even in an emergency when the power goes out - no batteries required. At just over 14 inches tall, Cowa is designed to sit on your countertop or on a table so you have easy access to water for drinking and cooking as well as making better coffee or tea.
Cowa reduces much more than your generic water filter. Tested in a third-party lab to NSF standards, Cowa has been certified for up to 400 gallons to reduce lead, other metals - including arsenic - chlorine, pharmaceuticals, pesticides, cysts, and bacteria. Depending on the number of people using it, that's about 6 months to 1 year of clean water before having to replace the filter element and 10 times the capacity of generic filters.
Check out the value you get with Cowa versus existing alternatives. Save money and drink better water.
Relax. Cowa's got your back
The top container will hold up to 2 gallons of water. Simply pour in, and wait. We recommend filling right before bed!
The ceramic element in the filter does two things: it keeps out bacteria and protozoa, and it slows the flow rate down. If you let the filter sit overnight, you'll have about 5 L of clean water by morning. This slow flow is needed to let the carbon reduce the many chemicals that may be in your water.
With Cowa, you can lay back, relax, and enjoy the clean water
We have already delivered samples to a local business in Kenya that is piloting our product.
In the United States, an EPA study showed that 20% of water systems tested high in lead. It's a problem we face at home, but a lesser known fact is that about 1.8 billion people, according to WHO, struggle with similar water quality issues worldwide. We created Cowa because it can solve this problem; our dream is to have it in the homes of families everywhere.
After riding a motorcycle around Nairobi, Kenya and interviewing different families, we learned that existing solutions, like using chlorine in a bottle or boiling water, were hated by almost everyone. The only other alternatives were out of most people's budget.
From our interviews, we knew Cowa could help. The biggest challenge is figuring out a sustainable way to get it there, so we're working with local businesses to get Cowa in more homes.

We're two mechanical engineers that met during our junior year at the University of Pennsylvania. We're passionate about simple designs, great technology, and businesses that do good in the world.
During our senior year, we were awarded the President's Engagement Prize from our university to explore water quality issues in an international context. The question we wanted to answer: why do people, in 2016, still struggle to get a cup of clean water?
Our journey took us to Oloitokitok, Kenya, a few hours southeast of Nairobi. There we stayed for a couple of months at Teule, an orphanage for young children, and we got to learn about the daily struggle many families face getting clean water.
So, as two engineers, we dove right in. We tested, we interviewed, and we learned. After those two months, we felt equipped with the information we needed to design our solution.
Shortly after returning to the United States, however, we heard the news of the Flint, Michigan water crisis that later became a national crisis. We realized this problem was larger than we originally thought - it was global, and it impacted us, too.
In Matt's basement, we had some power tools and time on our hands - a fun combination right after graduating from college.
After multiple tests and settling on the filtration technique to use, we designed the first Cowa with a ceramic and coconut carbon filter element.
After more iteration and feedback, we settled on the final design. We think you'll love it as much as we do. Get ready because this is just the beginning!
This past summer, we had the tooling for Cowa S made so that we could ship samples to local businesses in Kenya. That's why we are able to get Cowa S to our backers a few months earlier than Cowa T. Because we have already been through the manufacturing process once, we are confident we can deliver on-time.
Risks and challenges
We're working closely with Envirotek Laboratories, a NELAC accredited lab that is completing the testing our water filter. So far, we've been able to reduce lead, cysts, and metals like arsenic to NSF 53, chlorine to NSF 42, and bacteria (no NSF standard) for 400 gallons. Tests are almost completed to confirm its ability to remove pharmaceuticals and pesticides.
We've made it a point to find scalable, accountable suppliers. Our water filters are made in the United Kingdom from vendors with over 185 years of experience. Our plastics are made in southeastern China near Hong Kong, providing the necessary capacity to fulfill large quantities of orders. The major risk is that if shipments are delayed and/or something happens to our injection molds, there will be delays the manufacturing of our products. Rest assured, we've been very proactive to prepare our partners for this campaign!
