Welcome to our Hydrogen on Demand products page.
When we first started building HHO generators and installing Hydrogen on demand systems it was our intentions to be able to help those that couldn't afford expensive hydrogen on demand systems or elaborate hho generators. We stuck to modifying and perfecting the Water4gas type hho generators. These are a very good start for someone that wants to experiment with HHO Gas, but not so good for a lasting Hydrogen on Demand system.

HHO Dry Cell vs Wet Cell

We have moved way past the water4gas hho generator design and Now offer the very best  hho dry cell design.

HHO 2u is proud to have the best hho dry cells and hho dry cell kits available.  You won't find better hho dry cell construction.
If you find any lower prices than ours they are more than likely not the same quality. Please do your research before buying any type of Hydrogen on demand parts.

HHO2U's Hydrogen Generators and hydrogen on demand systems are built with The  highest Grade Material and come completely assembled and ready to install.
Only 316L  Laser Cut Stainless Steel Plate is used to make the electrodes.

Our HHO Economy DIY kit is a great deal for those that want to build their own HHO Electrolyzer (HHO Generator). Most of the hard work is done. Read the book and assemble it and you will have your own HHO Dry Cell generator built with your hands that looks like the shown pictures.
The HHO generator is the main component to a complete Hydrogen on Demand system.

Our HHO generators produce very good hydrogen levels at minimum amperage. With the improvements we have made to the original gasmaker hho dry cell design it produces twice the hho as the original single hole dry cells you will see others still selling.
We are not beginners in this hydrogen on demand technology and we know that there are endless choices of HHO generators out there, In fact we build many different sizes and styles.

The 3 hole design has proved to be the most efficient hho dry cell on the market due to the unique way the water is circulated. Check out these hho dry cell test videos.

The point is to bring to you a very affordable Hydrogen on Demand unit, that is DIY friendly and
that will give you good results to start, and can be expanded upon.
A quote from Ozzie:
Hydrogen On Demand technology is old - over 91 years old. All we've done is raise it from the dead, and develop a simple structure based on low cost hardware. Although there is a myriad of hydrogen generating designs out there, ours is the simplest and also the safest for the beginner.

We have come a long way since the water4gas hho generators, but have kept the same mindset - to help people get a hho generator that will give them good results for very little investment.

Our 11 plate hho dry cell puts out as much hho gas as a whole six pack of water4gas jars and much safer.

Thank You Ozzie for getting this HHO Gas revolution started !!

**  Please don't be fooled by other hydrogen generators and hydrogen on demand systems that are just here to make a quick buck using cheap materials, or deceptive tactics.We know that this unit will work for you because we have been running the same unit on our cars for many months.
