FAQ

We provide a fan and vent that should be installed to an external wall or ceiling. If on a boat, a common solution it to vent into the anchor locker. For more help with installation, check out our Installation Guide.

By seperating both, It helps to reduce moisture in solid waste, speeding up composting and massively reducing odors. It also helps manage nutrient levels, ensuring a more effienct process. Finally, it reduces the amount of times you will need to empty the solids tank.

Once urine and feces are separated, the solid waste is mixed with a carbon-rich material, like our Coco Peat Bricks, which act as a bulking agent. This mixture creates the perfect environment for aerobic bacteria to thrive. These bacteria break down the waste into compost, a nutrient-rich soil additive, through a natural, odor-free process.

Absolutely! More and more liveaboards are moving to Air Head Toilets because it allows you to be take your boat to areas which are tightly regulated by waste water laws or regular pump outs. It is also much easier to maintain, with fewer moving parts than a traditional manuel or electric head would require, meaning you can carry less spares, and spend less time dealing with toilet problems.

Yes, Air Head Toilets are completely custom. When ordering, you can choose which options suit your install best, allowing you to easily build the toilet around your space.

Check out our dimensions page for more detail!

Optimal composting occurs at temperatures between 55°F (13°C) and 100°F (38°C). Within this range, the aerobic bacteria that break down waste are most active, leading to efficient composting and odor control. At lower temperatures, the composting process slows down, as microbial activity decreases. Conversely, if the temperature gets too high, it can kill the beneficial bacteria or lead to excessive moisture loss, hindering the composting process. The Air Head is designed to maintain a balanced environment for composting, but it’s beneficial to be mindful of external temperatures.

Generally, restrictions will be different depending on location, but typically it is ok to use any compost in flower beds, or in your garden, just don’t use it on anything you plan to eat (fruit or veggies). It is generally permitted to dispose of it in the trash as long as it is in a sealed bag. But you are still advised to consult local authorities to find out if there are any location specific rules to follow.

  1. In general, there are very few things that can go wrong in your system, which makes maintenance great. However, if you are going away for months or years, we recommend that you carry:

    • Fan Replacement: Keeping a spare fan (and electrical wiring) ensures the ventilation system remains operational.
    • Spare Lids: In case you drop or misplace a lid for the liquids, order a few extra.
    • Bulking Agent: While not a “part,” having an extra supply ensures you can maintain the proper composting mix.

    Having these items ensures that you can deal with most maintenance or repair needs without a trip to town, keeping your system running smoothly in off-grid situations.

Yes! Our brand new model, Tejo, has been designed with this in mind. Simply install a hose directly between the Air Head, and your thru-hull (allowing for a vent or loop above water line to prevent sea water coming back in). By eliminating the urine on the toilet, it reduces the amount of time you need to remember to empty the toilet

Yes! There is no better option for RVers, either full time, or weekenders. It opens up so many opportunities to not have to find sites with pump out facilities, or places which sell chemicals. Instead, you are free to roam wherever you want, not planning your route around your toilet!

So, the solids tank can take, on average 80 uses. So, if 2 people use the toilet every day, it will last 1 month. But if 2 people are only using it at weekends, it can easily last a full season. Of course it can be emptied more frequently if you are happy to do so. For liquids it will also depend on usage. But, for 2 people, the small tank will need emptied every 1-2 days, and the large tank will last 2-4 days.

When at home, solids from your Air Head should be emptied into a dedicated compost pile or bin, where they’ll further decompose into usable compost for non-edible plants. Away from home, the solids can be placed in a biodegradable bag and disposed of in a trash receptacle.

The fan is designed to provide continuous air flow, aiding in the composting process and helping to minimize odors by evaporating excess moisture. While it’s generally recommended to keep the fan running to ensure the system operates effectively, it can be turned off for short periods if necessary. Extended periods without the fan may hinder the composting process and could lead to increased odors.

We make it as simple as possible. Clean the unit with natural cleaners to maintain hygiene. Inspect and clean the fan and vent system for unobstructed airflow, and agitate the composting material to aid decomposition. Check the rubber seals for integrity to prevent leaks and odors. Adjusting the bulking agent helps maintain optimal compost moisture. Following these simple routines ensures your toilet remains efficient and hygienic over time.

Winterizing the Air Head Composting Toilet in an RV or boat involves a few key steps to ensure it remains functional and odor-free during colder months:

  1. Empty the Unit: Empty both solids and urine containers before cold weather.
  2. Clean Thoroughly: Use natural cleaners for a thorough clean of the entire unit.
  3. Add Antifreeze: If occassionally in use, add non-toxic antifreeze to the urine bottle.
  4. Maintain Ventilation: Keep the fan and ventilation system running to prevent moisture build-up.
  5. Insulate Pipes/Vents: Insulate external vents or pipes against freezing.
  6. Monitor Moisture: Adjust bulking material addition to manage moisture in colder temperatures.
  7. Use a Heater: In extreme cold temperatures, consider a small heater near the unit to maintain composting temperatures.

Absolutely! We have made the install very user friendly for anyone to be able to have up and running in a few hours. Simply follow our installation guide, here:

Yes, additional hoses can be added to the Air Head Composting Toilet to accommodate longer vent paths. This flexibility allows for customized installation in various settings, including RVs, boats, and off-grid homes, ensuring effective odor control and proper air flow regardless of the distance to the exterior vent point.

It’s best to avoid chemical-based household cleaners, like bleach, in you Air Head as they can disrupt the composting process by killing beneficial bacteria. Opt for natural, non-toxic cleaners like vinegar, baking soda, or eco-friendly products designed for composting toilets. These alternatives keep your toilet clean and ensure the composting system works effectively and safely for the environment.

Our brand new model, Tejo, was built with this in mind. It comes without a urine tank, which allows you to install the urine directly to an existing holding tank. This allows you to go much longer without emptying tanks, improving the whole experience.

Things you should know in advance

There are pros and cons to this toilet that I didn’t understand ahead of time. The pros are well articulated on the website. I wish I understood the cons better.

1. The tankless version doesn’t come with installation instructions made for it. They are repurposed from the original. This made the install more frustrating than it needed to be, particularly on how you should handle the liquid draining to an under the waterline through hull. It doesn’t simply drain by gravity if you don’t add a way to introduce air between the drain hole in the toilet and the line. It seems as though this could have been built into the toilet.

2. The toilet needs to vent to the very aft of your vessel or you will fill the air with toilet smells that are more prevalent and throughout the living area of the boat than a standard toilet, albeit a bit more tolerable than the typical smell from a saltwater flush toilet. This is a very difficult task on my catamaran. Make sure you have a clear path to the furthest most aft void in your boat before purchasing.

3. The mounting hardware is flimsy and the screws will loosen and your toilet will move around unless you regularly retighten the ****.

4. The hand cranking isn’t the easiest. An upgrade would be for this to be motorized and perhaps on a timer.

Would I do it again? I’m not sure. It feels like a trade off of inconveniences. I expected more given the cost and effort to install.

*UPDATED FEEDBACK AFTER CONVERSATION*

A productive conversation with Joel regarding his installation provided us with an understanding of why his toilets were not draining properly. Both toilets are installed so that the urine drains directly out of the boat approximately 24' below the waterline. This is problematic because the water pressure at that depth pushes back on the outgoing fluid and thereby restricts the flow.. Also, the installation is not legally acceptable since the Air Head is an MSD type 3 or no discharge device. The product is sold as a no discharge device and therefore was intended to run urine to a tank. When installed in this manner, the product will drain without the need for a pump so long as the tank is vented to relieve air pressure.

Joel also mentioned odor coming from the vent and confirmed that it is a musty odor rather than a sewage type of smell. He believed that the odor was exiting the on deck vent and re entering the boat via downwind hatches when they are open. We have found this to be normal and recommend in our manual to avoid using vents directly forward incoming vents or hatchs. A possible solution for Joel's installation could be placing the exhaust on the outer or inner hull.

*ORIGINAL FEEDBACK*

Hi Joel,

Thank you very much for leaving a review! We really appreciate it. A few comments below:

The hold down brackets must be touching the solids tank when installed otherwise when they are tightened, the brackets will bend inward creating spring tension. The spring tension will cause them to loosen with sea movement.

The Tejo use manual was included, along with an instruction manual from the Classic which aside from the Tejo not having a bottle describes the installation which is exactly the same. A new manual is underway but has taken much longer than expected due to staffing issues. We wanted to make sure we could launch Tejo ASAP, and for us this was best option.

If you need any more help, please get in touch with us via email.

Perfect solution for off grid living

Hello everyone,
I installed the Tejo model on the 40ft trawler that I live aboard full time, and I love it! Its design is very much like a traditional household toilet that it is way more comfortable than a typical marine head. It is so nice to not have to deal with monitoring the level of the holding tank, and paying for pump outs!
Great job to the folks at Airhead, and thank you for making this product.
I tip my hat to you all.
Peace

Thank you so much for the positive feedback! We hope it makes your life onboard even better!
