Question: Do dehumidifiers help with allergens?
Answer: In the home, humidity over 50% can increase mold and house dust ite allergens, which can worsen allergies. In this case, dehumidifiers are helpful in reducing humidity below 50%.
When the dehumidifier fan is running, moist air from the living spaces is drawn into the unit via the inlet duct. It passes through the filter to remove air-borne contaminants, then continues on through the cold evaporator coil which causes the moisture to condense on the coil, much like condensation on the outside of a glass of ice water. The moisture falls into a stainless steel drain pan and is carried away by the drain hose. The air then passes through the condensing coil where it is warmed before being discharged into the living space. To maximize this process, a thermostatic expansion valve provides precise refrigeration control over a wide range of operating temperatures.
