Inspired by the design of a manhole cover, its unique structure features a single central opening and circumferential grooves, making it easy to clean while helping reduce residue and contamination. Made of fully transparent, heat-resistant glass, the funnel allows users to observe the filtration process. It is available in funnel diameters ranging from 8 mm to 185 mm, and the RHOTO 55 (55 mm), RHOTO 150 (150 mm), and RHOTO 185 (185 mm) models are compatible with commercially available filter paper.
