This is not the cheaper "prefilter" material that most people are selling on eBay when it comes to flat filters. The prefilters are great for taking out the larger sediment, but they don't catch the fine stuff that these filters do. They only get the large particles. Ideally, it is best to use them together. Filter through the prefilters and then through these. That will help keep the larger sediment from clogging this fine Orlon filter.MAPLE SYRUP FLAT FILTER - SYNTHETIC ORLON - FOOD SAFE - MADE IN THE USA! Brand new item.
