No, because it has already condensed on the heat exchanger and runs off there.

Furthermore, you rarely/never have 30-degree warm air with 75% humidity in these latitudes - typically it is over 10% lower.

Do you really believe that you have discovered something that apparently all manufacturers/buyers/distributors/institutions have overlooked? Do YOU really think there would be a construction approval if the part were a breeding ground (which it would be 100% according to you)?

The condensate forms at the WT and then what happens next? Then you have air at temperature X after the WT and rRF 100 percent. What likely happens afterwards in the ducts when condensate has already occurred in the WT.

No, I certainly have not discovered anything totally unknown. The hygienic problems of ventilation systems are known. Conveniently hushed up and ignored by controlled residential ventilation sellers.

Good question. If the filter has the same specifications as the one in the controlled residential ventilation system, why not.

For example, I bought my coarse filter from a filter shop – they are all identical, whether for controlled residential ventilation, range hood, etc. (in my case: G4, 20mm thick, as installed by the manufacturer in the controlled residential ventilation system ==> 2 sqm = €16.99 ==> lasts half a controlled residential ventilation system's lifetime ).

Why have my pipes been bone dry for 14 months, including the condensate drain in summer? Why are the hygienic problems of ventilation systems known and yet kept quiet?

Because you, me & all of us just have no idea - finally understand that, nordanney

Luckily, we have not yet died from germs with our controlled residential ventilation...
