    • The other commercially available purifiers claim performances on the oxygen and water level purification that are >50 times worse than those of the two purifiers we tested. It will be clear from our analysis that even 1 ppb of water is critical in achieving narrow linewidths in the AlGaAs/GaAs/AlGaAs QW system: as a consequence we did not invest in testing them, also in view of the substantial financial cost this would have implied. It should be said that technical papers on some of the existing commercial purifiers seem to suggest that their performances are better than the producer specified values (see Ref. [7]). Nevertheless it is not the subject of this paper to analyze the performances of all commercial purifiers available, but only those underlining the importance of an appropriate purification strategy.

    • All samples have been grown also with the same hydride and metalorganic sources, all far from "depletion" effects. We indeed stress that in our comparison the only variable that changed over time is the arsine purification levels.

    • Thanks to private communication from Maxime Hughes we were made aware of a single exception to our statement: at Sheffield University QWs with extraordinarily narrow linewidths, down to 150 μeV, showing no charged exciton shoulder in PL have been studied.
