“This is really about the unit overall. It is very noisy and I cannot sleep next to it so it is impossible to put on at night when the condensation is at its worst. Flap always needs to be open and so looks ugly. Bought these two new filters for it and the instructions to change them are ridiculously jargon-y and complicated. Generally this unit has not solved my ventilation problems and I’m pretty I happy with the product overall.”
