Guzzle Product Questions

Guzzle H2O drinking water systems are great for any situation where available water is just not good enough...whether there is a health risk due to parasites, bacteria, or viruses, or if the taste or smell leave you less than thirsty. We want water to be reliably clean every single time. 

Our systems contain a carbon block filtration component, which screens sediment, turbidity, and absorbs much of the chlorine and chloramine that municipalities add to treat their water supply.

The UV-C LED purification step will inactivate 99.99% of the protozoan parasites, bacteria, and viruses from your drinking water. (This is the part that saves you from extra trips to the toilet!)

Other products you may see at an outdoor store aren’t quite the same. They often require pumping by hand or long wait periods that rely on gravity. Most products don’t address BOTH palatability and microbiological hazards. Some will do a single water bottle in a short period of time, but that’s it. Others are difficult to recharge.

Our products use only the best components that are third party tested. We use the same UV purifier that they use on the International Space Station. We use a two-step process to ensure that nothing gets by in the way of contaminants. Our Stream is in a rugged and durable case that can go with you anywhere. It can filter and purify 32 gallons of water on a single charge, while pumping from a creek or other body of water, OR seamlessly connect to faucets. Our Stealth is designed to be installed on a plumbed system and draws the smallest amount of power possible and only draws power when the faucet is open and water is flowing. 

Additionally, our products can filter and purify water for your entire group. No special bottles needed. If you take the price of a personal purification bottle or system and multiply it out for your family, biking buddies, fishing friends, etc, our products would quickly become more cost effective.

We designed Guzzle H2O drinking water systems to give you the highest and most reliable performance in the industry.

Product Questions

As you can see from our website, we have three drinking water systems...the Stream, the Stealth, and the Spigot. 

In short, the Stream is our highest end product at $950.00. One of the reasons it is at the higher end is because it is a fully self sustained system. This fully portable, battery powered unit, can filter water from a pressurized source, a jerry can, or even a body of water such as a creek. It’s robust, easy to use, and nearly instant. No waiting or pumping.

The Stealth retails for $525 and is the unit we designed to be installed in your van, camper, RV, boat, etc. It’s plumbed into the existing plumbing and uses a 12v power source. This unit has a flow system so that when you turn the faucet on, it senses the water flow and turns itself on. You can see an example Stealth installation diagram on the Stealth product page.

The Spigot also retails for $525 and is built to be used on pressurized water sources. It has a battery, but does not have the pumping system that the Stream contains. We use this one most often at campgrounds or marinas that have a tap water connection, but maybe not good, quality drinking water. 

In order to work its best, the pump typically needs to be within 6 feet of the water source. We suggest taking the Stream down to the edge of the water source and then pumping through a long hose into the vehicle’s tank. The Stream will pump 32 gallons on a single charge, so it would easily fill your 20 gallon tank in about 15 minutes. To recharge the Stream on the go, you would need a 12v charger or a solar panel setup. This would also be the ideal setup for backup jugs and water bottles.

If you want a second round of filtration and purification onboard, you could add also install a Stealth, which would treat any water coming out of the onboard tank and into the drinking faucet.

When you order a Stream, you pick either a 12v or 110/220v charger. You can add the other charger on as an option. We also have a solar panel setup if you’ll be off the grid. Please see all of those in Accessories.

No. The unit has a flow sensor that turns the LED UV on instantly when the water moves through the system. It immediately switches off when the flow stops.

It runs on 12v and draws about 1 amp when water is flowing. Otherwise it does not draw power. For installation instructions, please see our manual.


The Carbon Block Filter component removes sediment, turbidity, and absorbs much of the chlorine and chloramine that municipalities add to treat their water supply. Doing this makes drinking water taste and smell much better. Carbon Block filtration is the best know process for improving the taste of water.

The UV-C LED purification component of the Guzzle H2O will inactivate 99.99% of the protozoan parasites, bacteria, and viruses from your drinking water. 

Ingestion of microorganisms typically leads to infection of the gastrointestinal track. Symptoms may begin in 10 hours, or may take up to several weeks from the point of infection depending on the type and amount ingested. Also the overall strength and and constitution of the individual is a factor. Symptoms may include diarrhea, abdominal cramps and pain, nausea, vomiting, muscle cramps, fever, fatigue, headache, chills, loss of appetite, and, in the case of hepatitis, dark urine and jaundice. Symptoms usually dissipate in a couple of days or weeks, depending on the factors above. Healthy adults will generally defeat the illness without needing medical attention. Infants, young children, elderly, pregnant, and immune-compromised individuals are at higher risk of needing medical attention or having complications from an illness.

A filter removes contaminants from water by passing the water through a porous material and physically removing contaminates either mechanically or through molecular attraction. A purifier inactivates organisms in the water to standards set by the EPA. Guzzle H2O uses ultraviolet rays to inactivate protozoa, bacteria, and viruses. Some filters can remove most protozoa and bacteria, but typically cannot remove viruses. The Guzzle H2O system performs both filtration and purification to make your water delicious and safe.

The Guzzle H2O systems are most effective at removing sediment and turbidity as small as 0.5 microns, chlorine, chloramine, poor taste and odor, and inactivating 99.99% of protozoa, bacteria, and viruses.

In the process of filtering water, activated carbon is often used to remove contaminants and impurities. Carbon is very good filtration medium because of thousands of tiny pores that can absorb water. For example, a pound of activated carbon provides 125 acres of filtering surface area. The carbon is positively charged to attract negatively charged impurities such as chlorine, chemicals and volatile organic compounds.

Carbon block filters are the most effective, since there is a larger ratio of activated carbon surface area to water, and also because the powdered block form is denser and water travels through it more slowly. The larger surface area created by the block carbon, and the more time the water is in contact with the carbon, the more contaminants are removed.

Ultraviolet (UV) water disinfection technology has become an increasingly popular tool in water treatment over the past two decades, due in part to its ability to provide treatment without the use of harmful chemicals. UV represents wavelengths that fall between visible light and x-ray on the electromagnetic spectrum. The UV range can be further divided into UV-A, UV-B, UV-C, and Vacuum-UV. The UV-C portion represents wavelengths from 200 nm - 280 nm. UV-C photons penetrate cells and damage the nucleic acid, rendering them incapable of reproduction, or microbiologically inactive.

Inactivate means to destroy a pathogenic organism by breaking up its DNA and rendering it harmless.

The carbon block filter is tested and verified to remove 85% of particles 0.5 microns or greater.

The Guzzle H2O systems reduce chlorine, chloramine, and some VOCs. It has limited effectiveness on heavy metals, pesticides, and concentrated chemicals.
