We keep seeing people trying to use our U-shaped filter papers in V-shaped drippers like the Hario V60… and then wondering why they split or cause uneven extraction.
They’re not defective — you’re just using the wrong shape!
If you want a perfect fit for your V60-02, grab our EE1402s – they’re made for it. No folding, no fuss.
But if you insist on using our U-shaped ones (EE1078 size 4s or EE1086 size 2s), because they’re about half the price of Hario’s, then at least fold them properly so they don’t split.
Yes, the shape mismatch can cause uneven extraction — but if cost’s your priority, this simple fold trick makes them work surprisingly well.
