Ultrafine bubbles (UFB) do not rise like larger bubbles, instead following a random Brownian motion within liquids for long lifetime and stability (up to months). Some research attributes enhancement in thermal conductivity to the motion of fine and ultrafine bubbles which may improve efficiency in boilers and heat transfer systems.

The strong surface charge, greater zeta potential, in UFB results in better attracting opposite charged oils and dirt particles as well as repelling like particles for greater colloidal dispersion and prevention of scale. UFB also collect and release free radicals upon collapse (namely the hydroxyl radical) which act as natural oxidizers to reduce biofilm and odors in baths, toilets, kitchens, and piping throughout the home.
