Do it Yourself Corsi-Rosenthal Box Air Filter: Improving Air Quality During Winter
Addressing Winter Air Quality Concerns
This winter break are you traveling to be with friends and family? Or are you staying warm inside by a fire? As we feel the chill in the air, it's important to also focus on preserving air quality during the winter season. There are unique considerations for indoor air quality during winter. The risk of colds, flu, and other respiratory illnesses is more common in these colder months. Preparing a home for gatherings can mean using lots of cleaning products. Many cleaning products can be harmful to your health and worsen indoor air quality. Lots of scented products like candles are popular during the holidays to create a festive and pleasant mood. Scented candles can contribute to indoor air pollution. Even the smoke from a fire contains fine particles that can affect air quality and respiratory health.
But these are some of the greatest joys of winter! As we stay warm inside, we need to consider indoor air quality. If indoor air quality becomes unhealthy, it can have a range of negative health effects, including respiratory disease, cardiovascular disease, and negative cognitive effects.
The Corsi–Rosenthal Box (CR Box) air filter was developed in response to growing awareness about the health risks of bad indoor air quality. The CR Box air filter is intended to provide an affordable and effective solution to improve indoor air quality. This innovative air filter is named after the two researchers who developed the concept, Dr. Richard Corsi and Dr. Brandon Rosenthal. From our perspective, the CR Box air filter is one of the best air filters for a home, office, or classroom.
Across the world, many people and local organizations have built their own CR Box air filters using the instructions provided by Corsi and Rosenthal.
Building your own CR Box air filter is a rewarding and practical Do-it-yourself (DIY) project that can improve the air quality in your home or workspace. By following the instructions, you can create a portable air cleaner using a standard box fan and MERV 13 filters. The CR Box air filter has been shown to reduce indoor particulate matter concentrations by up to 85%. The filtration is also very good for collecting very small particulates too small to be seen by the human eye. Yes, these include airborne materials in solid or biological forms, and dry or moist droplets ranging from animal dander to cough or sneeze discharges.
There are several detailed online resources available for those interested in learning more about the amazing CR Box air filter. The best resource is the Corsi-Rosenthal Foundation. A few of our other favorites are Clean Air Crew and Schools for Health.
As you prepare for festive gatherings, or take a breather after eating holiday cookies, consider incorporating the construction of a DIY CR Box air filter into your holiday plans. Whether you are looking to reduce your chance of a cold or airborne illness or minimize the impact of dust and other airborne pollutants from cleaning and scented products, constructing a CR Box air filter is a cost-effective way to improve air quality.
