Just look at the water packaged in soldered tin (not steel) cans that were hand dipped in enamel during World War II.  Because the water was pressure cooked in the can (killing all the bacteria), and the can was seamless (not allowing bacteria to get back into the water), the water is still bacteria free and good to drink even 50-70 years later.  

Because we are certified bacteria free and our bottles don't allow for bacteria to re-enter the water while in storage, we offer a 20-year guarantee that your Puravai water will remain pure and secure.   Each bottle is date and time stamped to help you keep track of when you bought it. 

We don't cover problems as a result of improper transportation or storage conditions, such as allowing the water to freeze (ice may form and damage the protection seals) and/or if the product is stored near chemicals, sharp objects, or other hazards that may compromise the integrity of Puravai bottles and the water inside.  

It doesn’t rust, it doesn’t tear apart, it bends rather than breaks, it expands and contracts with heat and cold, it will last 100s of years without falling apart, and can be recycled over and over and over.

This isn’t weakling packaging! It’s thick and sturdy and because of that you can preserve your water from Water Vapor Transferring (WVTR) that occurs with store-bought bottled water or even aluminum pop cans. If you leave store-bought bottled water or aluminum pop cans on a shelf long-enough, the water vaporizes through the pores of the bottle and through the seams and thin skins of the pop cans, and your water supply gets lower and lower. And, with pop cans, it doesn’t help that the carbon-dioxide or the nitrogen gas creates pressure from the inside out, causing the water to escape even faster over time.

HDPE is actually one of the safest plastics and is FDA approved for potable water. Because of its high density nature, you don’t have the plastic chemicals leaching into the water like you would from a cheap plastic. That’s why HDPE is used for long-term water-storage tanks, such as those 55-gallon storage drums we’re familiar with.

This almost goes without saying, but if you leave a can of water out long enough it can rust from from the outside in and from the inside out. All it takes is for water to work itself into the seams of a metal can over time, and eventually the water seeps out.

The more seams, the more weak points, and the more chances of your water escaping over time or becoming contaminated. For example… Pouched water has seams sometimes on all four sides. A metal can has seams at the bottom (a very bad place for a seam!) and on the top. An aluminum pop can has seams around the top edge and another seam where it pops open (a very thin, weak seam, mind you!). But, thick HDPE plastic bottles are seamless. There is only a hole at the top that is sealed by induction and then a tight lid keeps it all in place for decades without the worry that water will eventually “seap” out of its seams.

As much as you think the aluminum in an aluminum can won’t get into your water over time, it’s not true. The aluminum gets in and heavy metals in water make the water un-healthy and sometimes un-safe.

Because of the thickness and the density of the HDPE (“High-Density” Polyethylene), water doesn’t get out and water doesn’t get in!! Try soaking a can in water over time (especially salt water), and see what happens (not a good thing!).  Being water proof means that your emergency water is protected from the corroding effects of basement flooding or even something as simple as humidity in the air. 

Yes, importantly, it’s BPA Free. Most cans can’t claim the same simply because of the food-grade coating they use on the inside of the cans.

One of the biggest flaws in cans are dents. When a can is dented, two bad things can happen. First, you create weak points or even cracks in the interior or exterior liners. This causes rusting over time for metal cans, and causes aluminum to enter the water with pop cans. Second, when you dent the bottom or top edges of a can, you have just weakened or maybe even ruined the seamed of the can. One small dent on the seam and your water can be ruined for life (which is bad if you plan on staying alive in an emergency situation). Dents aren’t an issue with sturdy HDPE bottles like Puravai uses.

Thick HDPE plastic doesn’t tear like pouched water does. So, it is safe to put in a 72-hour kit or let it roll around in a trunk or anything else. These bottles are tough!

A very beautiful thing about HDPE bottles is that it comes with a reusable cap. That means in an emergency, Puravai bottles can be used again and again, drinking from the bottles and then refilling them where needed, like a canteen. In fact, we make our bottle from the same materials the U.S. military uses to make their canteens.  You can’t say the same for pop-topped cans, opened metal cans, or torn-open pouches.

HDPE plastics are one of the most recycled plastics in the world and can be used and reused again. Did you know that even your store-bought gallons of milk are made from HDPE?

This is a big plus for emergency water, because you precious water supply is protected against flooding, rivers, lakes, or oceans. Emergency water that floats means an extra level of security in a variety of emergency situations and a great backup water supply for the U.S. Coast Guard and the Navy as they travel in the open waters. 

Soda cans are made to last about a year or so, not decades. Soda manufactures have spent years at finding and developing the thinnest, cheapest way of putting their drinks into a can, so they can maximize profit - that is the aluminum soda can! If these manufacturers were concerned about longevity, they would still be canning in pure tin cans like they used to during World War II or in thick HDPE plastic like we do, but that gets way too expensive and would cut into their profits.

Also, the liners inside aluminum pop cans are so thin that all it takes are little dents or some rough housing (something as simple as just shipping a product to your doorstep), and your water could get contaminated by soaking in the aluminum. That’s a very bad thing.

Soda cans also can collect bacteria and contaminants on the lids of the can over time or during a crisis, which can get you sick when you drink from it.  The pop-tap of the can is also designed to go down into the can, which can push those contaminants into your water even faster.  During emergencies, for example, chemicals and particulates float through the air or are able to soak the cans.  Those types of contaminants can cause sicknesses that can defeat the whole intent of drinking the water in the first place (including diarrhea or vomiting, which can dehydrate a person faster than that person can re-hydrate).  A good pre-packaged emergency water protects the drinking area where the mouth comes in contact with the container.  Soda cans are not built with that type of protection. 

Another thing to consider is that the seams and pop tops of soda cans are weak points.  Soda cans sometimes pop open over time from heat and cold shifts in the air and the CO2 or Nitrogen in the can even cause water vapor to escape through the micro holes in the seams of the can.  For example, go on Ebay.com and look for 20-30 year old soda cans. Most of the sellers talk about how their cans were NEVER opened, but all the liquid somehow is gone out of the can. Case in point!!

Are your bottles 100% recyclable?
