ᐅ Cross-flow countercurrent heat exchanger with condensate drainage

Hello everyone,
We have bought a terraced house built to KfW 70 standard that is currently under construction. Now we have to choose between a cross-counterflow heat exchanger with condensate drainage or an enthalpy heat exchanger (from Wolf).
The enthalpy heat exchanger costs an additional 1600 euros, because instead of the Wolf CWL-300, the CWL-400 Excellent would be installed.
We have heard that the enthalpy heat exchanger is better for moisture reasons, but there is also a risk of bacterial growth.
What should we do? The installer says: "no problem at all."
Thanks for your expert advice!
Regards

I have the CWL-300 with a cross-flow heat exchanger, and yes, in winter the humidity can drop to about 30% (30 percent).
Now about the enthalpy exchanger: where there is heat and moisture, there are also plenty of germs and so on—it’s simply natural. This means that without regular and thorough cleaning of this type of heat exchanger, an increase in germs can be expected.
The consequences of this can be clearly seen in poorly maintained air conditioning systems.
