Dry air is a natural byproduct of cold weather. As temperatures decrease, the outdoor air drastically loses its ability to hold onto water. When it becomes colder, you’re also more likely to turn on your home’s heating system. These two conditions together contribute to why your home’s air is too dry.

Most homes aren’t as insulated as they should be, so when you’re running your central heating system, you may be losing your conditioned heated air through cracks and walls. This lost air is then replaced in circulation with the cold and dry air from the outside. Unless there is enough moisture added from other sources like cooking, bathing, etc. the air will continue to get drier.

Your home needs to completely replace the indoor air with fresh air from the outside, at least eight times per day. However, if you’re losing all your conditioned air then there will be an imbalance of dry air present in your home. While there can be many sources for where your home is losing heat (walls, windows, cracks, etc.) the primary source for your dry indoor air is always the outside environment.

Knowing that the outdoors is the culprit for drying out your home, we can now discuss some solutions for improving your indoor air quality.
