Caution: Do not put water rinsed filters back into cleaning solution.
We recommend a strong sturdy plastic. The quality of plastics vary. Do not clean in cheap plastics.
Like with any cleaners we recommend wearing gloves, as skin sensitivities vary.
Unlike almost every other filter cleaner you don't need to wash your filter with soap after using F3. F3 has a self activating soap when rinsing in water so you no longer have to bother with that additional step!
NO! F3 is designed to be rinsed with water not diluted, the product will not clean effectively when mixed with water.
Testing shows that you could clean at least 10 filters effectively with 1qt / 946ml of F3 before replacing with new F3.
