WAVE ventilation is a brand name for a type of dehumidifier that is used in basements, crawl spaces and in structures that are built on concrete slabs. WAVE solves excess moisture problems by targeting the source of a moisture problem, which is the lowest area of the house. The dehumidifying unit extracts damp air from a home and utilizes the warmer above-ground air to reduce relative humidity.
According to the WAVE website, the WAVE basement dehumidifier gets rid of mildew and the problems associated with a musty basement. The dehumidifier also alleviates asthma and allergies.
A regular dehumidifier removes moisture from the air by the process of condensation and then re-circulates the same air back into a room. Therefore, WAVE technology is a more healthful alternative. According to the WAVE website, additional humidity in a home traps pollutants and thereby worsens such health conditions as headache, dizziness, fatigue, sneezing, eye irritation and respiratory distress. Moisture also increases the development of dust mites and mold.
The WAVE website states that it is a well-known fact that dry air is less costly to heat or cool than air with excess moisture. Therefore, WAVE ventilation lowers a homeowner's energy costs. The Department of Energy supports the finding, stating that it costs 17 percent less to heat and cool a home that utilizes mechanical ventilation such as WAVE technology.
