Originally, the “naked” portafilter was just another term that describes the bottomless design. Nobody knows who came up with that name, but it’s a creative way to say that these portafilters will let you see their private parts — the baskets! In 2014, Gábor Laczkó, a Hungarian entrepreneur, launched a brand that specifically sells naked portafilters, in addition to other espresso accessories. The only thing special about these portafilters is that you’ll see the word “NAKED” engraved on the side.
