I couldn’t figure out for the life of myself and others why I had to scrub our shower with bleach every other day. There was a mildew smell coming back within hours of every shower, even if it followed an intense cleaning session moments before I started shampooing our hair. I went through so much bleach cleaner in 1 week that I started developing allergy troubles with the chlorine odor in our house. I talked to people at the local hardware store, however few had any definite ideas on how to service the issue. It took a acquaintance of mine who works in residential Heating plus Air Conditioning to pose a possible explanation for our problem. She asked myself and others what the air flow is like to our lavatory from our central A/C. When I told him that there is no Heating plus Air Conditioning vent in our lavatory, only a roof ventilation fan, she told myself and others to get a small dehumidifier for the lavatory. With only minimal air flow coming in through the open doorway, it wasn’t enough to keep the lavatory dry. If an indoor space sustains a certain level of moisture, mildew growth is almost unavoidable. At the same time, I was skeptical that a small dehumidifier would make much of a difference on the air quality in our lavatory. To our amazement, it dropped the humidity level from 68% to 45%. I took a shower later the same day plus was astonished with how good the lavatory odored while I was toweling off. If I can’t get constant flow of conditioned air coming from the central A/C, at least I can dry out the lavatory to achieve much of the same effect. I don’t mind if I have to pay more on our electric bill to cover the cost of running a dehumidifier, it’s worth it to keep a sanitary lavatory.
