Why Winter Makes Indoor Air Quality Worse

Why Winter Makes Indoor Air Quality Worse

Homes are built to be energy- (and therefore cost-) efficient by holding heat in during the winter time and keeping heat out during the summer. Winter weather prompts homeowners to tightly seal any cracks in insulation that could allow cold drafts into the home. This, in turn, also seals off the home from any fresh air and raises the concentrations of allergens, pollutants and chemical concentrations in the home.

Add Stack Effect…It gets Worse!

indoor air qualityThe same force that causes hot air balloons to rise in to the sky is present in all of our homes. This “stack effect” draws air up from the lowest levels through floors, doors, windows, and up from the basement and/or crawlspace commonly called “chimney effect”. This stack effect or chimney effect is very powerful during the winter heating season actively introducing basement/crawlspace air up into the living environment contaminating the quality of indoor air.

40% of the air we breathe in the living spaces was once basement/crawlspace air!

Effects of Poor Indoor Air Quality

Immediate effects of poor indoor air quality can show up after just a single exposure and include headaches, dizziness, fatigue, and itchy eyes, nose, and throat. Asthma and chemical sensitivities can also be aggravated by exposure to indoor pollution. Allergic responses to pollutants in the air can last for months on end as the air quality continues to worsen. Chronic sensitivities may also build up after repeated exposures.

Although it remains uncertain what levels or periods of exposure are necessary to bring on serious health effects from indoor air pollution, long-term effects of indoor air pollution include respiratory disease, heart disease, and cancer.

Improving Indoor Air Quality

The EPA recognizes two basic strategies to improve indoor air quality: source control and ventilation improvements.

Improving indoor air quality through source control involves removing the sources of pollution. Gas emissions, like those from a poorly maintained stove, for instance, can be adjusted in order to lower their emissions; asbestos can be sealed or enclosed. Often, source control is a more cost-conscious way to remedy poor air quality, however source control is not always possible or practical.

Increased ventilation is an easy and effective way to control poor indoor air by bringing fresh indoor air into circulation. Especially because most heating systems do not bring fresh air into the home. Whole home ventilation systems not only create a path of escape for the myriad of pollutants trapped inside our homes, but also make room for better air to be introduced. Solution by dilution. Increase the amount of fresh air entering the building envelope is an effective way to improve the quality of indoor air

You can easily check to see if your home might have ventilation problems. Condensation on walls or windows, stuffy air, moldy areas, or dirty heating or cooling equipment are all indicators. Odors (which are most notable upon entering the home from outdoors) are also an indication of poor ventilation.

When performing many home improvement or hobbies, it’s especially important to be aware of the need for proper ventilation. Without ventilation, pollutants such those emitted during painting, welding, sanding, or even cooking, can add toxic elements into your home environment.

We are a 2nd generation family owned and operated business that has been working in homes with basements and crawl spaces for over 40 years.  We have been waterproofing and sealing about 500 foundations a month during that time as the largest Waterproofing contractor in the Midwest with 15 locations servicing 8 states.

20 years ago we would seal a foundation and recommend a standard dehumidifier to address the additional water vapor (humidity in the air) inherently found in below grade environments, such as basements and crawlspaces.  Back then, dehumidifiers were the industry standard to help with this problem. However, many of our customers were looking to us as the “foundation expert”, asking…

“What else do you have? I really am not getting results with this messy, expensive dehumidifier. My foundation is dry, walls are dry, floor is dry, so why does it still smell and feel like a basement?” 

We needed to find something better. Our company’s core values include offering world class customer service to every customer, every time.   So, we challenged our Research and Development department to find a real solution for our customers to combat not only the moisture, but also the odors, pollutants and unhealthy environment our customers were concerned about. We found, tested and installed a ventilation product for a period of three years. We private labeled that product as the EZ Breathe Ventilation System. The feedback in those first three years from our customers, as well as our installation crews, did not live up to the standard of quality to be included in our waterproofing process that offered a life time warranty. Once again, we needed something better.

We valued not only the results, but what we were learning from our customers. So, we went back to the drawing board, took matters into our own hands and made quality improvements to that first generation ventilation unit.

Our own EZ Breathe Ventilation System was born…reengineered, redesigned and much improved! We quickly learned that our crews were thrilled with the quality improvements, ease of operation and installation, but more importantly, our waterproofing customers loved the new, improved EZ Breathe unit as well.

Their feedback told us the air in their basements and crawlspaces felt better, but their entire home was benefiting from their EZ Breathe as well. We received countless letters thanking us because their whole house felt different, less odors, fresher air upstairs too, family members were feeling better, needing less allergy medicine, husbands were no longer snoring, children were no longer coughing as much, the home and it’s family were living healthier lives!

It was time for us to move beyond simply offering this innovative technology to just our waterproofing customers. Our passion and commitment to helping people improve their indoor air environments is what drove us to incorporate EZ Breathe Ventilation Systems as an independent company in 2003. We strongly believe that homeowners everywhere deserve a healthy indoor air quality.

We have spent the last 20 years dedicated to learning about the relationship between our home and our health; indoor air quality, the home as a system, building science and how it relates to indoor air quality as well as the challenges our modern day practices pose to the quality of air we breathe in our homes.
