Antlia vs Altair Triband RGB filter

[AstroMuni]

Are these effectively the same filter but from different providers? Both seem to transmit Ha, Oiii, Sii & Nii.

They're different thicknesses... Antlia 2.00 mm... Altair 1.85mm so I guess not

I'd also take those manufacturer supplied spectroscopy results with a very fine pinch of salt.

Cuiv on YT had tested his Altair filter and I believe it was good, but I think it's a bit of a lottery for the cheaper end of the filter game as to what you get is as per the bandpass graphs.
