The Perfect Fit For Your Lifestlye

Every style of install has unique challenges. Find out how we have built the perfect toilets for your lifestyle.


What are the key differences between the Classic and Tejo models of Air Head Composting Toilets?

The main differences are their design and use case. The Classic model is our time-tested solution, known for its robustness and reliability. The Tejo model introduces an innovative design and a larger bowl, which feels more like a traditional household toilet. Tejo also removes the liquids tank from the toilet, allowing users to install a remote tank elsewhere, or use an existing black tank.

Absolutely! Thanks to the rubber gaskets on the lid, seat and tank,  both the Classic and Tejo models are designed for installation in wet head/shower areas. These gaskets prevent water from entering the composting area, maintaining the effectiveness of the composting process.

Absolutely! Both models boast a user-friendly installation process, accompanied by comprehensive instructions to guide you every step of the way. The key distinction lies in the design aspect;Tejo does away with the conventional liquids tank in front of the toilet, which will add some additional setup. This might involve installing a new tank or configuring hoses to connect with an existing one. However, this design tweak eliminates the need for a front-mounted bottle, which shrinks the toilet’s footprint. This can actually simplify the installation in more confined spaces, making it a bit smoother overall.

There is no right or wrong answer here. Both are perfect for off grid living with regular usage. Depending on your use case and install, Tejo may offer the ability to use a larger remote black tank, therefore requiring less frequent emptying. However, maybe you can’t install a remote tank, or prefer a more classic approach to composting heads, in which case the Classic might be a better fit.

Both the Classic and Tejo models offer customization options to ensure your composting toilet fits perfectly with your space. However, the Classic model does offer more versatility when it comes to options.

Maintenance and cleaning procedures are very similar for both models. Simply use vinegar and water to clean out the tank, bowl and seat.

The choice between the Classic and Tejo models for a boat depends on your specific needs and space availability. The Classic model, with its self-contained design, is straightforward and efficient for smaller boats. The Tejo model, with the option to route urine to an external tank or directly overboard (where legal), might be more suited for larger vessels or those looking for a more traditional toilet feel and the ability to handle waste more flexibly.

For RV users, the Tejo model might offer an advantage due to its innovative design that resembles a traditional household toilet, providing a more familiar experience. Its ability to connect to an external tank can also be beneficial for managing waste in long-term travel scenarios. It is also the first composting toilet in the world to be RVIA approved (Recreational Vehicle Industry Association). However, the Classic model remains a reliable and efficient option, especially for those who prefer a compact, all-in-one solution.

Tejo introduces an innovative design that has a much larger bowl compared to traditional composting heads, which feels much more like a traditional household toilet. Tejo also removes the liquids tank from the toilet, allowing users to install a remote tank elsewhere, or use an existing black tank, again mimicking the look of a household toilet. It is the best option on the market for those with Off-Grid or Tiny Home set-ups.

It’s important to note that U.S. regulations prohibit the discharge of untreated urine into any waterways. However, internationally, this isn’t always the case. (Check your local laws and regulations)

Tejo was created to be able to direct urine to an external tank. However, in theory, you could also direct urine directly overboard via an existing thru-hull.

For the installation, we recommend connecting a hose from the Air Head to a Y-valve (diverter valve), with one outlet leading to an internal tank and the other to your thru-hull, incorporating a pump inline to prevent backflow and ensure efficient disposal. This setup reduces the need for frequent emptying, thereby enhancing the usability and convenience of your toilet system.

Again, always ensure compliance with both local and international maritime laws when configuring your system for waste disposal.

While the Classic model features an integrated liquids tank with a specific capacity, the Tejo model allows for the flexibility to connect to an external tank of varying sizes. This means that the Tejo can potentially handle a larger volume of liquid waste, depending on the external tank’s capacity. The solids capacity is very similar for both models, with no real world differences.

Both models are engineered to set the benchmark in composting efficiency. With the correct use of composting medium and regular agitation, they both excel in creating compost. Tejo, however, introduces an enhanced urine diversion system designed to more effectively separate liquid waste from solid waste. This means that the solids in the Tejo model are more likely to be dryer, which can accelerate the composting process. As a result, while both models perform exceptionally in composting, Tejo’s advanced urine diversion system may offer a slight edge in ensuring the solids compost more efficiently and effectively.
