Can we use our passive filters for third-party VSD?

It would be nice for schneider to sell passive filters, but reality is opposite.
All passive filter, that can be found in ATV catalogs have been designed and tested for use only with our drives. We, unfortunately, cannot offer passive filters for general use. Our passive filters must be considered as ATV accessory.
Well, third party VSD also consists of input rectifier, DC capacitors, maybe AC or DC, but it has different DC bus capacitance and inductance (AC or DC). As a result, the native spectrum of harmonics of third party VSD is different from harmonics spectrum of our drives. If third party VSD is combined with our passive filter, we cannot guarantee proper operation of VSD or passive filter, nor to declare the level of harmonics.
