IMS E61 Precision Filter Basket 16/20g - B702TH26.5M From  £17.52

This is a high quality filter basket, that I have used to replace the stock 2-cup filter basket that came with my ECM Classika. It has a slightly higher maximum dosage than the stock filter basket, yet fits within the stock portafilter just fine, is highly polished, is easier to clean, and seems to yield a bolder, richer extraction (perhaps due to the slightly greater capacity). I highly recommend it.

This Filter is made very fine surface , so good for dripping.
But its fitting for Rocket E61 porter handle is closely , and difficult to remove it.
