The UFO Special editions are the filters that perform the maximum potential, yield and fitting of the UFO dripper.
The filters ensure the no bypass but let extraction be driven through the UFO original air channels design, achieving an special and stunning cup profile.
The UFO dripper is a Jay and Kenzie development, they based all the R&D to create the UFO around the Sibarist filters due the performs consistently every single time. The UFO special edition goal is to share the utmost consistent brewing experience with the brewing community.
UFO: “We wanted to create a conical dripper that can not only capture clarity and complexity, which are characteristics of a traditional 60-degree wall angle conical dripper but also sweetness and even extraction of a flat bottom dripper, leading to cups with incredible clarity and intensity. Once we achieved that through UFO’s unique 80-degree wall angle, our next mission was to solve the consistency issue of a conical dripper. That’s when we designed our UFO air channels alongside UFO blocks that the filters sit on with enough surface tension to not collapse into the air channels. The result is something truly special, a cup profile that has never existed before. One that combines the best of the flat bottom and the conical geometry. We cannot wait for you all to experience it soon.”
There are two filter paper technologies available for the UFO dripper:
The B3 Specialty Coffee Filters (The filter is delivered unfolded, se HOW TO USE below)
“B3 flows slower than FAST. We enjoy B3 for fast flowing process impact-heavy (natural/anaerobic natural/carbonic maceration/co-ferment/yeast-inoculated, etc) coffees that require coarser grind sizes and a slower flow rate to provide sufficient contact time to extract all the good things while avoiding over extraction of the mega funky flavours that can often be overwhelming. This can also apply in roast levels. The more developed the roast, the more we will lean towards the B3 and grind even coarser.”
Using Sibarist Flat Papers
UFO was designed for use with Sibarist Fast flat and B3 papers, although this template can be used to fold any flat filter. Simply fold once in half, then fold to match the angle below (feel free to take a screenshot and print this diagram).
The SOLO HIFLUX Filter 165 is a custom-designed wave filter, developed in collaboration with HIFLUX to precisely match the geometry and flow characteristics of the SOLO dripper.
With a design that is both aesthetically refined and technically advanced, the SOLO dripper required a filter engineered to match its exacting standards. After extensive discussions, testing, and development, HIFLUX has successfully achieved this goal.
Throughout the process, the HIFLUX Team was strongly influenced by Jackie Tran, the creator of the SOLO dripper. His deep commitment to coffee and his outstanding design expertise have redefined the standards of modern specialty coffee brewing. It is clear why the SOLO dripper has earned admiration from brewers around the world.
About the Solo Dripper
George Jinyang Peng, the 2025 World Brewers Cup Champion, used the SOLO Dripper to win the prestigious competition in Jakarta. A seasoned competitor with vast experience, George impressed the judges with his smooth presentation and an award-winning coffee that showcased exceptional clarity and balance. The SOLO Dripper - featuring its signature 40° angle, curved base - played a crucial role in his success, delivering consistent flow, even saturation, and optimal extraction throughout his routine.
Optimized Flow Design
With a 40° internal angle and sloped bottom, the SOLO Dripper promotes smooth, balanced extraction. The geometry naturally directs water flow for even saturation, delivering consistent, clean cups with every brew.
Durable. Portable. Versatile.
Crafted from food-safe, BPA-free PCTG plastic, the SOLO Dripper is built to perform—whether at home, in a café, on the competition stage, or while traveling. The complete SOLO System includes:
A standalone dripper compatible with most glass servers
A dual-purpose ceramic server that doubles as a tasting cup
A compact, protective container for convenient travel
Each component is carefully crafted with thoughtful design details that elevate both the brewing process and the experience.
Outer support ribs provide a secure, balanced fit on a variety of brewing vessels - a holder is included for additional elevated support
Technical Specifications
The filter is made from a blend of high-quality European pulp and long Lyocell fibers, delivering clean and consistent extraction with excellent structural integrity. Its unique three-dimensional fiber structure, formed during the papermaking process, minimizes clogging and promotes even flow, ensuring optimal brewing performance.
Designed in Prague, SOLO embraces geometric harmony and purposeful design.
Los colores de los productos reales pueden verse ligeramente diferentes a los de las fotografías del producto. Esto se debe a las distintas configuraciones de los monitores. Cada monitor o pantalla móvil tiene una capacidad diferente para mostrar colores, y cada individuo puede ver estos colores de manera diferente. Además, las condiciones de iluminación en el momento en que se tomó la fotografía también pueden afectar el color de la imagen.
Los productos que tienen una capa brillante también se verán de manera diferente bajo diferentes configuraciones de iluminación. Los colores pueden parecer diferentes incluso bajo una luz fluorescente o una bombilla de pantalla más cálida.
Designed for the curious brewer. The Solo Daily wave paper filters feature an accelerated flow rate that opens up new territory in your pour-over, enabling you to grind finer, extract more, and let the coffee's natural oils carry through to the cup.
Expect a rounder body and a noticeably smoother finish.
Each pack: 50 filters, size 155.
