Our He[%] filter baskets are produced using CNC machining and laser cut hole technology, VST or IMS baskets are pressed products, and both the hole and shape are created by press and polish machines.
Our He[%] filter baskets use 1.1mm thick steel and are perfectly cylindrical, while IMS/VST uses a thinner layer of steel and the top diameter is different from the bottom diameter.
Our He[%] coffee filter baskets have an overall more significant amount of holes and open surface area compared to IMS and VST. The laser technology allows the holes of HE to be closer to the edges.
