IMS Competition Convex Filter Basket for 58mm Bottomless Portafilters (18g) B702TCH24E
The 18g convex competition basket is designed for bottomless 58mm portafilters, delivering a ridgeless, convex bottom to promote even extraction. It fits most E61 group head portafilters and aligns with 58.5 mm tampers. This model emphasizes a smooth flow profile to reduce channeling while preserving crema and sweetness. Its convex geometry, combined with a precise hole layout, aims to balance near-center extraction for consistent shots from smaller doses.
IMS Competition Convex Filter Basket Nanotech 58mm (18-22g)
This 18-22g convex basket incorporates Nanotech coating to repel water and coffee oils, facilitating cleaner cups and easier cleanup. The center-weighted hole pattern supports uniform flow through the puck, while the convex bottom and ridgeless design promote even extraction across the distribution. It is tailored for Verybarista equipment and similar 58mm bottomless portafilters, making it a solid option for cooks seeking reduced sticking and smoother channel control in a single-dose or light-dose regime.
IMS Competition Convex Filter Basket for 58.5mm Tampers (20g) B702TCH26E
This 20g convex competition basket features a ridgeless, convex bottom designed to optimize water distribution in bottomless and standard 58mm portafilters. Its design supports a larger dosage with consistent flow, reducing channeling and promoting a balanced extraction. The basket is compatible with most 58.5 mm tampers and a broad range of 58mm group heads, including popular E61 machines. The aim is to deliver cleaner pulls with a sweet, full-bodied finish.
MHW-3BOMBER 58mm Espresso Filter Basket (18g) Double-Layer
The MHW-3BOMBER dual-layer basket offers 18g capacity with 745 laser-drilled perforations to support precise extraction. The inner layer prevents ultra-fine particles from escaping, while the outer layer enhances extraction efficiency. The 58.5mm diameter is generally compatible with most 58mm portafilters, though some models may require removing the stock portafilter bottom to fit. This configuration emphasizes uniformity and a clean cup profile, with notes of sweetness and balance across typical double-shot brews.
Oruola 58mm Portafilter Basket, Double Layer
This double-layer pressurized basket supports a 2-cup capacity, designed to deliver a smoother, richer espresso with a reliable crema. Made from stainless steel for durability and rust resistance, the basket’s layered construction aims to improve flavor extraction while simplifying cleaning. It is positioned as a versatile option for home and small-shop machines, particularly when replacing worn baskets in 58mm portafilters.
IMS Big Bang Precision Filter Basket 18-20g (Center-Heavy)
The Big Bang design focuses on a high-density center with 585 holes to drive forward a robust flow. The arrangement is intended to reduce channeling and deliver a consistent sweetness across the shot, with a preference for 18-20g dosing. The basket aims to create uniform extraction, particularly on bottomless setups where flow paths are more exposed to the coffee puck.
IMS Big Bang Precision Filter Basket 22-24g
This 22-24g Big Bang basket extends the same center-weighted perforation concept to a larger dose, promoting a sweet, balanced cup through increased hole density near the center. It is designed to support fuller extractions without sacrificing clarity or crema. Compatibility spans most 58mm portafilters and common commercial machines, with careful attention to the group head depth and tamper size when choosing a larger-dose basket.
Buying Guide
- Dosage range: Choose baskets that match your typical shot size, whether 18-20g, 20g, or 22-24g, to optimize balance and sweetness.
- Hole pattern and geometry: Center-focused holes and convex vs ridgeless bottoms influence flow, channeling risk, and extraction uniformity.
- Coatings and materials: Nanotech coatings can aid cleaning and oil repellence, but ensure compatibility with your portafilter and cleaning routine.
- Compatibility: Confirm fit with your 58mm portafilter and tamper dimensions (58.5 mm vs 58.0 mm) and whether your machine is E61 or other group heads.
- Bottomless considerations: Bottomless designs highlight flow behavior; beginners may experiment with smaller-dose baskets first to observe puck dynamics.
- Maintenance: Some baskets offer easier cleaning due to smoother surfaces; regular backflushing and careful drying help maintain performance.
- Extraction goals: For sweetness and crema, central hole density and total perforations matter; for clarity and brightness, consider holes distribution and material.
These baskets provide options across convex, double-layer, nanotech, and Big Bang styles to accommodate varied brewing preferences, from home setups to studio environments. When selecting, consider your typical dose, machine compatibility, and desired cup profile to maximize espresso quality without excessive trial-and-error.
