OREA WAVE
Since OREA's inception, many people have inquired about WAVE filter paper (cake filter paper/wavy filter paper), but frankly, we've always struggled to find a better alternative than existing products on the market. Therefore, we've always persisted in searching, rather than launching inferior products. After years of searching, we finally found a filter paper that satisfied us and launched it under our own brand. This filter paper is thick yet highly breathable, outperforming similar products. We don't particularly like the flatness of this filter paper, but we love its wavy designâwhich allows its advantages to be fully displayed.
WAVE filter paper is the simplest filtration method; just place one in the filter cup and you're ready to brew. If you'd like to try more types of filter paperâfor example, coffee that brews faster or has a higher extraction rateâwe also have the Negotiator system to meet your needs. If you simply want an easy-to-use method, then this corrugated paper is the perfect choice.
