4 1/2 inch Replacement Glass Bowl - CLEAR
This bowl is 4 1/2 inches in diameter.
Simply measure the diameter of the top of your diffuser to make sure the top of your diffuser is 'smaller' in diameter. Then, this bowl should work for you.
Example - the top of your diffuser measure 4 inches - this bowl will work for you.
If the diffuser base measures 4 1/2 inches it MIGHT work. This will work on all Ceramic, Glass or Soapstone diffusers.
This bowl does not have a 'flat' bottom.
