    What is the increase of oil life if filtered daily?

    Community Answer
    It's best to filter after each use, if possible, rather than daily, if you fry more than once a day. Frying for longer times reduces the lifespan of the oil, but you could see 5 - 10x the life of the oil through filtering.

  • Question
    What are some scientific explanations about this purification of oil?
    Bozobub
    Community Answer
    It's just removing matter from frying that can continue to cook, then burn, ruining the oil for later use. It's simply the science of filtering out particulates.

  • Question
    Using this method never worked for me. The standard coffee filter always ended up clogged by the oil, even when there were almost no food particles in the oil. Why?

    My money is on oil temperature being too low. The oil might be too thick, so it's easier to get trapped in the filter.

      Tips

      • You can filter the oil at room temperature but the oil will flow better when it is warm.
        Thanks
      • Dark oil, after filtering, is a sign the oil maybe breaking down and is not in pristine condition. However dark does not mean bad oil.
        Thanks
      • Ideally, select a mason jar or jars that will hold all the oil and keep the bottom of the filter out of the clean oil.
        Thanks

      About This Article

      Article Summary X

      To filter fry oil for reuse, start by scooping out any large chunks of food from the oil and then letting the oil cool to 150-170 degrees Fahrenheit. Next, secure a coffee filter or cheesecloth over the top of a jar and pour the warm oil into it. Then, after you add the oil, wait a few minutes for it to filter into the jar. Finally, remove the filter, seal the jar, and set it aside for the next time you want to fry food. To learn how to secure a coffee filter or cheesecloth to a jar lid, scroll down!
