OREA WAVE
Since OREA was founded, many people have asked us about WAVE filters (cake filters / wave filters), but to be honest, we have always found it difficult to find a better option than what is already on the market. Therefore, we have always insisted on searching rather than launching an inferior product. After years of searching, we finally found a filter that we are satisfied with and are launching it under our own brand.This filter paper is thick while also having good breathability, offering performance that is superior to similar products. We aren't fond of the flat version of this paper, but we absolutely love it in the wave design—where its advantages are fully realized.
WAVE filters are the simplest way to brew; just grab one, put it in the dripper, and you’re ready to start. If you want to experiment with different types of filters—such as those that offer faster flow rates or higher extraction yields—we also have the Negotiator system to meet your needs. If you just want a simple and easy-to-use method, then this wave paper is your ideal choice.
