Pollution is often thought to be an outdoor air issue; however, the indoor spaces where we spend the majority of our time can become equally or even more polluted with organic and inorganic materials such as VOCs, molecular contaminants, and harmful particulates. Spending extended periods in indoor spaces with poor air quality can result in health concerns such as irritation of the eyes, throat, and nose, allergies, headaches, and even fatigue and reduced productivity.

At Hollingsworth & Vose, we manufacture air filtration media for high-quality control of contaminants, temperature, and humidity to maintain a safe and comfortable indoor air quality. Our innovative filtration media are made from the highest-quality materials to improve the energy efficiency of HVAC components and remove air contaminants. We offer various solutions to improve and maintain indoor air quality and deliver the benefits of high air quality.

Why Is Indoor Air Quality Important?

Indoor air quality (IAQ) is vital to reducing the transmission of viruses and other contaminants for the improved overall health of indoor air. Unfiltered indoor air can be as much as five times more contaminated than outdoor air, and Americans typically spend nearly 90% of their days indoors. Whether it’s time spent at the home, office, school, or in other public buildings, the air we are breathing is often a threat to our health.

Recent studies show enhancing IAQ may reduce aerosol virus transmission by as much as vaccinating 50 to 60% of the population against the same viruses. Contamination of indoor air has also shown links to cardiovascular diseases and respiratory allergies. H&V’s high-efficiency filtration media delivers reliable protection against indoor pollutants reducing exposure to unhealthy air and promoting better occupant health and productivity.
