How it works

A Composting Toilet That Diverts Liquids and Solids

The “Air Head” Composting Toilet works simply. By separating liquids from solids, the volume of solid human matter is significantly reduced. Air Head’s approximate five-gallon capacity means that up to a season’s worth of weekend use may be held. (Based on solid matter volume for two persons’ use twice every weekend for five months: 80 uses). A liveaboard couple can expect 60 uses (one month) before they’ll have to empty the solids tank.

Toilet Bowl Open and Closed

 

Much like a household toilet the “Air Head” Composting Toilet has a bowl and an actuator which provides a “flush.” The main difference is the “Air Head” Holding Toilet’s waterless operation. A paper bowl liner acts as a carrier for solid matter on its way to the solids tank.

The solid matter is separated and agitated, thereby decomposing it into a non-offensive state inside the large tank. Additionally, the unit has an integral 12-volt fan that provides a constant negative pressure to pull moisture out of the living space. Even after long lay-ups, there is no “holding tank” smell when you come aboard.

Crank handle and inside the bowl

 

Liquids are collected in the smaller forward tank. Its wide-mouthed aperture will keep the contents emptying smoothly into any standard commode.  The liquid tank will hold approximately four days use per person if used exclusively.  A low-profile bottle is also available that holds about half the volume of the standard bottle.

Additionally, the “Air Head” may be integrated with an existing holding tank system, creating holding capacity for both solids and liquids far beyond what many medium and small boat owners are used to. This is because the tanks take on no flushing water and are free to hold just what they need to.

Why Do Our Customers Love Air Head?

I keep telling our customers about your (Air Head) system. We now have been using it for 8 years. We are doing the Baja HaHa this year. I’ll make sure to let all the cruisers about AirHeadToilet.

Thank you for designing such a great product. Airhead is the first boat toilet we have had that didn’t have any odour! My wife loves it. We no longer dump our maceratored sewage into the Georgia Strait, so that feels good as well. We will sing your praises to all we meet…

The airhead composting toilet is a fantastic toilet for van life. It’s the best composting toilet on the market.
