You can find plenty of small and inexpensive dehumidifiers at any home goods store, but these models are only designed to regulate air moisture in one or two rooms at a time. If you have a full size basement with a damp problem or live in a humid climate that permeates the entire home, invest in a whole house dehumidifier instead. This kind of efficient equipment offers the damp-fighting homeowner five different benefits.
Better Air Volume Processing
Since portable dehumidifer units circulate so little air each minute, most products sold for a single room don't even list the cubic feet per minute (CFM). Whole house units offer higher CFM rates than smaller units because the goal is to completely process the air in the entire house or targeted space multiple times per hour, also known as air changes per hour (ACH). The ideal CFM is calculated based on the needed ACH due to the humidity levels, so a 1000 square foot home needing four ACH will need a device with a minimum CFM of 67. Most portable units barely provide 10 or 15 CFM, which is enough for a single room but nowhere near the requirements for handling a bigger humidity problem.
More Precise Humidity Control
Afraid of drying out the air in your home so much it causes sinus and skin dryness? Get precise control to balance moisture removal with your family's comfort. The electronic controls and high-tech touchscreen thermostats let you raise and lower the humidity levels by tiny degrees. Some devices even hook up to your whole house automation system that connects to your smart phone for constant monitoring and access.
When a member of the family is diagnosed with asthma or allergies, invest in a whole house dehumidifier to control their symptoms. The professional grade dehumidifier provides allergen control by
- Reducing humidity to prevent mold and mildew from growing and releasing spores
- Trapping any existing mold spores and other tiny allergens in the air filters
- Cutting back on dust mite colonies, since the mites need high humidity levels.
If cleaner air is a concern along with the control of humidity levels, choose a whole house system fitted with HEPA filters, electrostatic filters, and even UV lights for disinfection. This allows you to enjoy the benefits of air purification while getting a handle on dampness and musty odors.
Many people assume that room-sized dehumidifiers are the best choice when they only need to dry out a basement or a single room with water damage. However, whole house units still do a better job even when you only need limited air treatment. The HVAC installer simply connects the duct work to whichever parts of the home need dehumidification, and you can set up as many separate zones as you like to change the humidity levels in different parts of the home. The large and central compressor is easily expanded to the rest of the house if you need whole house control later.
Less Structural Damage
Excess moisture in the air does more than just encourage mold growth, it also accelerates rot hidden inside the walls and attic. If roof damage from a falling branch leaves your attic water damaged, the rot threatens your home's stability even after the leak is repaired and the space dries out. Room dehumidifiers barely process all the air inside the room, while a powerful whole house unit transfers enough air each day to maintain a dry environment inside the wall cavities and other enclosed spaces too.
If you're concerned about investing in such a large upgrade to your home, keep in mind it raises your property value for reselling. A dry house stays intact and clean longer, making it more attractive to buyers even when you wait decades to sell it. Get the equipment professionally installed by someone like Allcounty Plumbing Heating & Air Conditioning to make sure it is properly sized for your home's air volume and your humidity lowering needs.
