The PropelAir uses just 1.5 litres of water to flush the bowl, compared to up to 9.5 litres of water used in conventional toilet cisterns! The toilet was designed by Phoenix Product Development. It works when the lid of the toilet is closed over the bowl, which creates an air-tight seal. A small amount of water is used to rinse the bowl, then air is used to displace the waste.
The flush works in just 3 seconds. The bowl is then filled with more water to act as an odour trap. It’s pretty similar to an airline toilet in the way it works. There’s no rim on the toilet bowl, meaning it’s more hygienic and easier to clean. Impressively, the PropelAir toilet doesn’t used compressed air to flush the toilet, it uses air at atmospheric pressure.
The toilet is not yet available to purchase, but you can register your interest on the designers website.
