## Notes

The **shallowest** basket in IMS's NanoQuartz-coated B70 line — 20mm, rated
11.5–13.5 g for a dark roast and 13–15 g for a light one. If you dose in the
low teens, this is the NT basket that keeps the puck filling the basket instead
of sitting at the bottom of a deeper one.

## The NanoQuartz coating

The Nanotech line's whole point is the surface. IMS describes the coating as
enhancing water flow, preventing coffee oils from sticking and making cleaning
effortless — in its own technical words, 'Electropolished & Nanoquartz coated',
'highly resistant to chemical corrosion' with residue removed 'with a simple
wipe'. Under the coating it is competition geometry: 715 holes of 0.30mm in a
hexagonal pattern across a Ø49mm perforated face, flat-bottomed and cylindrical.

## The full NT ladder

| Code | Height | Dark | Medium | Light |
|---|---|---|---|---|
| [B702TFH20NT](/baskets/ims-b70-competition-nanoquartz-2-cup-h20/) | 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 |

Five codes, and that is the whole family — the table above is IMS's own, so
there is no sixth NT height to hunt for. Every one of them carries the same
Ø70mm border and Ø60mm body, so the choice is purely dose.

Same official B70 compatibility as the rest of the series. Gaggia machines take
the narrower B68 series and are deliberately not cross-referenced.

  - Official IMS Filtri product page ('B702TFH20NT FILTER BASKET' — 'E&B Lab - Nanotech B70', '2 Cups - H20 Nanotech Flat'), read firsthand 2026-08-21. Specs verbatim: 'Border: Ø 70 mm', 'Body: Ø 60 mm', 'Height: 20 mm', 'Tamper: Ø 58/58.4 mm', 'Coating: Nanoquartz', 'Pattern: 715 Holes'; technical specification 'Perforated Area: Ø 49 mm', 'Holes: 715 (Exagonal pattern)', 'Hole Diameter: 0.30 mm', 'Finishing: Electropolished & Nanoquartz coated'. Described as a 'Cylindrical filter with a flat bottom featuring the exclusive Nanoquartz coating'. The page's 'Capacities Comparison (NT Series)' table gives this height as 11.5/13.5 gr (dark roasted), 12/14 gr (medium) and 13/15 gr (light), and lists the whole NT family as exactly five codes: B702TFH20NT, B702TFH22NT, B702TFH24NT, B702TFH26NT and B702TFH28NT.
- 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.
