For example, a relative humidity of 35% means that the air is holding 35% of the total moisture it is capable of holding. Generally, one does not want to have a home humidity any lower than 30%. It is recommended that your home’s relative humidity should be kept between 30% and 55% during the winter. Without a humidifier to moisten the dry winter air, lower relative humidity levels can aggravate skin allergies and respiratory infections. Dry air can irritate nasal passageways and also lead to increased mucus production, which can be dangerous for people with asthma. Conversely, in the summer a humidifier can combat higher levels of humidity that increase the spread of mold, bacteria and viruses. Dust mites also spread when the humidity is above 50%. Humidifiers provide clean, healthy air by maintaining proper levels required for quality air and by preventing the growth of bacteria, mold, and algae and arresting their growth.
In the middle of winter, with little moisture in the air, humidifiers can bring humidity up to preferred, healthy levels to help fight asthma symptoms. Humidifiers add moisture to the cool, dry winter air by restoring moisture to your body. During the cold months, many homeowners will complain of indoor air so dry that it causes itchy skin, dry throats and cracked nasal membranes. Dust and allergens tend to fall to the ground when the humidity is slightly higher and become airborne when this moisture is too low. In the winter months, that basically means that it is easier to get sick which we know to be true. In the summer, mold spores and pollen can combine with high humidity levels to aggravate asthmatic individuals. The use of a humidifier can help monitor the humidity in your home and regulate it accordingly. Many homes are equipped with humidifiers that are connected to their overall HVAC systems, but portable humidifiers are increasingly popular and extremely effective as well. Asthma can be a crippling sickness to deal with, especially in the winter time when it may be difficult to breathe. Investing in a humidifier is an excellent way to improve your homes air quality while protecting people with asthma.
