Treating the air in your home should be #1 on your list of home improvements!
Dry air absorbs moisture from your skin and everything else in your home. Dry air can increase your likelihood of getting colds, flu and other upper respiratory ailments. Viruses that cause colds and flue thrive in dry air. It can also make people more susceptible to infection and can aggravate allergy and asthma symptoms.
Dry air may also cause damage in your home. Along with static electric charges that could cause your electronics to need expensive repairs or replacements, it also causes walls, woodwork and hardwood floors to crack.
