I have a condensation problem and understand that fitting a passive humidity vent would go some way to alleviating this problem.
The difficulty is that I have been recommended three specific units at similar prices but had no idea which is the best.
Passyfier vent www.condensationshop.com/products/passyfier/
Fresh 99H by Passivent

Aereco EHT 17 40
What is your experience with either of these and which would you recommend for moisture/humidity absorption?
