Do you also feel that your whole home is wet in spring and summer? It is a worrying problem and should be actively addressed if the indoor relative humidity is above 60%.
Whole-house dehumidifiers are HVAC devices that help you be proactive and effectively reduce humidity levels throughout the house.
Data from an analysis of indoor humidity levels show that more than 36 percent of U.S. homes have humidity levels that exceed the EPA’s maximum recommended value of more than 60 percent. Especially in summer, if there is no house dehumidifier, the humidity can reach more than 80%. Basements and crawl spaces were particularly humid, with relative humidity above 90 percent.
If the whole house dehumidifier is not available, there is a potential hazard in high humidity. Uncontrolled humidity has the following effects:
- The man. High humidity can easily cause respiratory tract allergies, such as asthma, nasal cavity, allergic rhinitis, and other problems.
- Mold and mildew growth. High humidity is an ideal environment for mold growth. Using a whole-house dehumidifier to reduce indoor humidity to less than 50% is the most effective way to prevent mildew from growing.
- Structural damage. Prolonged high humidity levels, especially in basements, can erode and shatter walls (moisture causes corrosion and reinforced concrete rusts). If the humidity in the walls of a building reaches more than 80 percent, the entire structure of the house is in danger. It also significantly reduces home values.
To prevent and avoid these problems, protect the health of your family and yourself, create comfortable living spaces, and keep your building and its contents safe, the EPA recommends that homeowners reduce indoor humidity levels. Indoor relative humidity should be kept below 60 percent, ideally between 30 and 50 percent.
Here we need to distinguish between two types of whole home dehumidifiers:
- Large pipe whole-house dehumidifier. Built-in tubular HVAC system, dehumidification ability is powerful and can ensure the accurate humidity adjustment in the room. Can cover every room, basement, crawl space, etc. The downside is that the price is slightly higher, about $1500 each.
- Small portable household dehumidifier. A knee-high unit that can dehumidify a single room and be moved from room to room effectively acts as a dehumidifier for the entire room. The unit is trendy because it only cost $200- $300, but to achieve the effect of a Large pipe whole-home dehumidifier, you need to purchase 2-3 of these devices.
