M; It’s rainy season around the corner. Humid and high temperature are good for mold especially in the bathroom.
F; Yeah…,I clean the bathtub and bath floor every time after taking bath because wet and warm room is easy for many bacterias.
M: I mention you…do you regularly clean the ventilation?
F; Do you mean the bath ventilation and dryer which works 24 hours all round a year?
M; Yes, I do. I happened to try to clean the ventilation on the ceiling and took off the filter for the first time ever since rebuilding the new bath room for 5 years.
F; Oh….what happened?
M; I was astonished at the filter covered with black mold!
I was really scared of it and went to outside to wash it out!
F; Was it for 5 years’ built mold?
M; It was! I didn’t notice it until yesterday. I’ll often check the filter at least once a month as well as washing out the bathroom walls.
F; I’ll also check it A.S.A.P.
