That model name is an IMS product code — series, cup count, height and hole pattern are all encoded in it. IMS basket codes, decoded explains how to read one, and lists every code covered here.
The shallower of IMS’s two NanoQuartz-coated B70 doubles — 22mm against the
H24’s 24mm, and rated
14–16g for a dark roast rather than 16–18g. If you dose in the mid-teens rather
than 18g+, this is the one that keeps the puck properly filling the basket.
The Nanoquartz coating is the point of the Nanotech line: a non-stick,
corrosion-resistant surface that releases the puck cleanly and wipes out easily.
Underneath it is competition geometry — 715 holes of 0.30mm in a hexagonal
pattern, Ø70mm border, Ø60mm body, flat profile.
Same official B70 compatibility as the rest of the series: E61 and
58/58.4mm-tamper machines from La Marzocco, Rancilio, Lelit, Rocket, ECM and the
Breville Oracle. Gaggia machines take the B68 series instead. Verified against
IMS’s official product page and Competition catalogue.
Other items confirmed to fit machines this one fits — useful if you're kitting out a single setup. The count is how many of those machines overlap; nothing here is a new fitment claim.
What size portafilter is the IMS B70 Competition NanoQuartz 2 Cup H22 (B702TFH22NT) for?
It is a 58mm basket, 22mm deep, for 58mm portafilters.
Is the IMS B70 Competition NanoQuartz 2 Cup H22 (B702TFH22NT) pressurized?
No — it is a non-pressurized (single-wall) basket, for freshly ground coffee.
Does the IMS B70 Competition NanoQuartz 2 Cup H22 (B702TFH22NT) fit 54mm machines like the Breville Barista Express?
No. It is a 58mm basket, so it does not fit Breville's 54mm machines or any 54mm portafilter.

Amazon listing verified firsthand 2026-08-03: 'E&B Lab, by IMS Nanoquartz Precision Basket with largest filtration area of 715 holes. For about 15 grams. B702TFH22NT' — the B702TFH22NT code in the listing title matches this entry exactly, including the NT NanoQuartz coating suffix. Add-to-cart present, i.e. actually buyable, at the time of checking.
https://www.imsfiltri.com/IMS-competition-Catalogue.pdf(archived) — 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.
