Two practical effects: the spent puck releases cleanly instead of clinging to the walls, and coffee oils do not bake onto the surface, so the basket stays closer to new with a rinse rather than a scrub. It is a **surface** treatment, not a geometry change. Ø70mm border, Ø60mm body, 715 holes, Ø58/58.4mm tamper — the same as the uncoated line. If you want the same dose without the coating, the plain B70 baskets are the equivalent. ## Heights in the NT family | Code | Height | Dark | Medium | Light | |---|---|---|---|---| | B702TFH20NT | 20mm | 11.5/13.5 g | 12/14 g | 13/15 g | | [B702TFH22NT](/baskets/ims-b70-competition-nanoquartz-2-cup-h22/) | 22mm | 14/16 g | 14.5/16.5 g | 15/17 g | | [B702TFH24NT](/baskets/ims-b70-competition-nanoquartz-2-cup-h24/) | 24mm | 16/18 g | 16.5/18.5 g | 17/19 g | | [B702TFH26NT](/baskets/ims-b70-competition-nanoquartz-2-cup-h26/) | 26mm | 18/20 g | 18.5/20.8 g | 19/21 g | | [B702TFH28NT](/baskets/ims-b70-competition-nanoquartz-2-cup-h28/) | 28mm | 20/22 g | 20.5/22.5 g | 21/23 g | Worth noticing: the NT range's capacities move far less across roast levels than the convex E-series does — a couple of grams rather than several. Pick by dose, and check the [code guide](/guides/ims-basket-codes/) if you want to decode the rest of the suffix. Same official B70 compatibility as the rest of the series. Gaggia machines take the narrower B68 series and are deliberately not cross-referenced. ## Sources - https://www.imsfiltri.com/filters/B702TFH26NT.html - Official IMS Filtri product page ('B702TFH26NT'), read firsthand 2026-08-11. Specs verbatim: 'Border: Ø 70 mm', 'Body: Ø 60 mm', 'Height: 26 mm', tamper 'Ø 58/58.4 mm', 'Coating: Nanoquartz', '715 Holes'. The page's NT-series capacity table gives this height as 18/20 gr (dark roasted), 18.5/20.8 gr (medium) and 19/21 gr (light), within a family running B702TFH20NT (20 mm) through B702TFH28NT (28 mm). IMS describes the coating verbatim as 'a specialized non-stick treatment that makes the surface highly resistant' to sticking. - https://www.imsfiltri.com/IMS-competition-Catalogue.pdf - Official IMS Competition Series catalogue, read firsthand 2026-07-04, whose 'For tamper 58 / 58.4' B70 compatibility list names La Marzocco, Rancilio, Lelit, Rocket, ECM and 'BREVILLE (The Oracle)' among the fitting brands — and 'FLAIR ESPRESSO (58)', which is why the Flair 58 is cross-referenced here; Gaggia is assigned to the narrower B68 series, so B70 baskets do not cross-reference Gaggia machines. --- Compatibility reference, not a substitute for your machine's manual.
