Controlled residential ventilation Dry air - is a humidifier the right solution?

Hello friends of controlled residential ventilation,

I hope I'm not bringing up a thread that is too old, but the thread title does not yet fully do justice to its content. Because besides an enthalpy exchanger, an active air humidification system also belongs to the class of "humidifiers." And this is exactly where my question comes in:

My heating engineer recommends a controlled residential ventilation system from Pluggit. As is well known, this company does not offer enthalpy exchangers and mentions among other reasons:

[*
Only part of the moisture can be recovered, so air drying in winter is only delayed.


[*]This has already been mentioned here. Of course, if you regularly shower or engage in other moisture-producing behaviors, there should be enough moisture. But one can question how generally valid that is for everyone.


[*]The moisture is transferred in an enthalpy exchanger by osmotic effect. Thus, on the supply air side, there will always be a water film on the membrane that the supply air must absorb.

[*]Bacteria cannot pass from the exhaust air to the supply air side because the membrane pores are too small for microorganisms. But on the moist supply air side, bacteria can form in the water film present in the warm environment. Manufacturers always argue that the pores are small enough and say they additionally coat the membrane with an antibacterial layer. In my opinion, they do the latter precisely for this reason: if the impregnation did not exist, bacteria would form on the supply air side. Otherwise, this coating would not be necessary because from a physical standpoint, no bacteria can penetrate the membrane from the exhaust air side to the supply air side. So for me, this is an indirect proof that this can be a problem (!). Otherwise, the impregnation would not be carried out.
[*]Does anyone also know how long such an antibacterial impregnation is effective? Every impregnation loses effectiveness sooner or later.


[*]Active humidity control. You can individually set your humidity, which is controlled via a control loop with a humidity sensor in the exhaust air.

So now the question: Is the investment in an actively controlled hot steam humidifier, such as the one Pluggit offers, worthwhile based on the reasons mentioned? The price is comparably steep—approximately 2500 € compared to 500-1000 € for a passive enthalpy exchanger. Additionally, there is the electrical power consumption, for which I have no feel yet (of course, it depends on the choice of humidity).

Thanks a lot for your opinions and experiences
