Are composting toilets, like Air Head, legal?

Yes, both Air Head Classic and Tejo are classified as a MSD type III.

What happens to the smells in the solid tank?

Once solid matter enters the main tank, anaerobic bacteria die off within a few days due to airflow. Aerobic bacteria then thrive, breaking down waste without foul odors. Solids are mixed under the composting medium and agitated to encourage aerobic activity, producing only a mild earthy scent. The included external fan and vent carry away any residual odor.

Why is urine and feces separation important in composting toilets?

Separating urine and feces reduces moisture in solid waste, speeds up composting, and minimizes odors. It also improves nutrient balance and reduces how often the solids tank needs to be emptied.

How does it make compost?

Solid waste is combined with a carbon-rich material, like coco peat bricks, which support aerobic bacteria growth. These microbes naturally break down waste into compost, a nutrient-rich soil additive, in an odor-free process.

Is the Air Head suitable for Marine liveaboards?

Yes. Liveaboards prefer Air Head because it reduces pump-out needs and meets wastewater regulations. A cruising couple usually empties the solids tank once a month. With fewer moving parts than standard heads, it’s easier to maintain and more reliable long-term.

Is the Air Head suitable for RVs?

Yes, it’s an excellent option for both full-time RVers and weekenders. Perfect for boondocking, it removes the need for dump stations or harsh chemicals, letting you travel freely without waste-related restrictions.

How often should an Air Head be emptied?

The solids tank averages about 80 uses. For two people using it daily, that’s roughly one month before emptying. Weekend use can stretch it through a season. Liquids tanks vary: the 1-gallon version needs emptying every 1–2 days, while the 2-gallon lasts 2–4 days.

Where do you empty the solids?

At sea, solids can be discharged offshore outside U.S. legal limits. On land, solids can go into a compost bin for further decomposition or be bagged and placed in regular trash. Never dump waste in inland lakes or restricted coastal waters.

Can the fan be turned off for periods?

It’s best to keep the fan running continuously to aid composting and control odors. Turning it off for long periods slows decomposition, increases odor risk, and may allow insects to enter. Short interruptions are acceptable if necessary.

Can the Air Head be ordered in any orientation?

Yes. Each Air Head unit can be customized for your installation needs, including orientation options to best fit your available space.

How much space is needed for a proper installation of an Air Head?

Air Head’s rounded design allows installation in compact spaces. Exact dimensions are available on the sizing guide page to ensure compatibility with your setup.

What specific maintenance routines are recommended for long-term use?

Recommended routines include cleaning the bowl with vinegar and salt, inspecting the fan and vent, agitating the compost regularly, checking seals, and ensuring moisture balance. These steps keep the toilet efficient and odor-free.

How does temperature affect the composting process in the Air Head Toilet?

The ideal temperature range is 55°F–100°F (13°C–38°C). Composting slows below this range as microbial activity decreases. Excessive heat can harm bacteria and dry out the medium, disrupting composting efficiency.

What is the recommended procedure for winterizing the Air Head in an RV or boat?

To winterize: empty both tanks, clean thoroughly, add non-toxic antifreeze to the urine bottle if used, keep ventilation open, insulate vents or pipes, monitor moisture, and use a small heater in extreme cold.

Can I install the Air Head myself?

Yes. The Air Head is designed for straightforward DIY installation, typically completed in a few hours using the provided guide.

How much power does the 12v fan use?

The 12v fan uses about 0.06 amps per hour, equaling roughly 1.44 amp-hours over a full 24-hour day, making it very energy-efficient for continuous operation.

How much does an Air Head Composting Toilet cost?

Prices vary depending on model and configuration, but typically range between $1,000 and $1,200. Accessories or add-ons may increase the total cost.

How long does an Air Head Composting Toilet last?

With proper care and maintenance, an Air Head can last more than 15 years. Replacement parts are available if needed.

What cleaning products are safe to use with Air Head?

Mild, natural cleaners like vinegar and salt are safe. Avoid harsh chemicals such as bleach or ammonia, as they can damage the toilet and disrupt composting.

Can I use regular toilet paper with Air Head?

Yes, but thinner or quick-dissolving toilet paper is recommended. Air Head also offers paper carriers to keep toilet paper tidy in compact spaces.

Does the Air Head Composting Toilet require electricity?

The Air Head uses a small 12v fan for ventilation, which consumes about 1.44 amp-hours per day. It can also run on solar power or a household 110v transformer.

How heavy is an Air Head Composting Toilet?

The full unit weighs approximately 25–30 pounds, making it easy to install in boats, RVs, cabins, and tiny homes.
