It is easy to become so concerned about excess air leaking from your home in the winter that sometimes you end up forgetting that there are some things that should escape, like pet dander, dust and smoke. Additionally, the warmer temperatures indoors serve as a breeding ground for dust mites, cockroaches, rodents, fleas, ticks, moths, and molds.
Indoor winter air can be anywhere from two to five times more polluted than outdoor air. In some cases, the air can be up to 100 times more polluted! Since people generally spend significantly more time indoors during the colder months (as much as 90% of our time is spent inside during winter), this poor indoor air quality is especially troublesome, particularly for young children, seniors and those who suffer from allergies and asthma.
If you’re still not convinced that the air in your home is that bad, then consider this: in the United States, indoor air quality is listed as one of the top five environmental risks to the public health by the Environmental Protection Agency.
While allergens are always present in your home air, many people find that their symptoms get worse in the winter since they become shut in with all the pollutants.
