Celebrate Earth Day With NanoWave® Filter Media

Leave a Comment

earth dayWhile Earth Day is an important time to celebrate nature and the beauty of the outdoors, at Hollingsworth & Vose, we are doing our part to make the air quality in buildings safer through filtration solutions that reduce energy consumption and minimize carbon emissions as compared to standard filtration in the market.

With energy consumption in buildings contributing over 30% of U.S. greenhouse gas emissions, and HVAC equipment accounting for 40% of commercial building energy usage, our team is motivated to help overcome these energy burdens through the introduction of advanced filter media that achieves better and more sustainable outcomes.

Air filtration is a critical requirement for healthy indoor air quality, but one that often involves making difficult decisions around higher energy expenditure to achieve the increased levels of filtration needed to keep building occupants safe and productive. That’s because it generally takes more energy to move air through higher-grade filters in HVAC systems (such as MERV 13-16), meaning more energy usage is the trade-off for cleaner air.

When considering indoor air quality, can we live in a safe and more energy-efficient world, having our cake and eating it too? A recent study conducted by on the carbon handprint of our NanoWave® filter media, an industry game-changer given its low-pressure-drop-to-performance ratio, revealed that building owners don’t have to compromise with higher energy usage for a safer indoor environment.

After reviewing our manufacturing processes and considering the energy use savings against comparable filter media, the study showed that NanoWave® emits 32 times less carbon and generates a savings of -326 kgs CO2e per filter use from cradle to gate. To put that into perspective, those savings are roughly the same amount of carbon emissions that a car ride from Massachusetts to Michigan would generate using regular gas.

The filtration industry admittedly has much work to do to continue improving manufacturing practices as responsible contributors to the green economy. At H&V, we are passionate about driving sustainable innovation to fulfill our mission of creating a cleaner, healthier, more sustainable world. If you are interested in learning more about how NanoWave® can help reduce HVAC energy consumption and lead to better outcomes for people, buildings, and the planet, please contact us at


Wishing everyone a happy and healthy Earth Day from the team at Hollingsworth & Vose!

Hollingsworth and Vose Continues Its Pursuit of a Cleaner, Healthier, More Sustainable World

Hollingsworth & Vose has an innovative and insightful outlook that helped to grow the company from a family business established over 200 years ago to a global leader in the advanced filtration industry today. Our company’s primary goal is to develop sustainable filtration solutions for a cleaner, healthier world.

Josh Ayer is the CEO of Hollingsworth & Vose. He came to the company in 2009 as the Vice President and Managing Director for their Asia Pacific Region. He then became the President and Managing Director of the Americas region, followed by President and Chief Operating Officer.

International Filtration News (IFN) recently interviewed Ayer for their ”Executive Q&A” article. Ayer spoke about the dedication and commitment that Hollingsworth & Vose has to the research and development of sustainable filtration and energy.  

How Has Hollingsworth & Vose Grown and Become an Industry-Leading Innovator?

As a global manufacturer of advanced materials for filtration, battery, and industrial applications, Hollingsworth & Vose always strives to maintain innovation in everything we do. 

Since our origins in 1728, we’ve expanded our manufacturing and research development into facilities in America, China, Europe, and India. Our greatest strengths are foresight and the ability to meet market needs and create a positive impact as they arise. 

During Ayer’s interview, he explained the company’s success, ”I think it’s always been key for us as a company to keep innovation at the forefront of what we do. That is what has allowed us to evolve and thrive for so long.”

Ayer also mentioned the following reasons for H&V’s past and continued growth:

  • An international presence that has contributed significantly to our role as an industry leader.
  • Our 13 worldwide research and development, and manufacturing facilities, allow us to partner economically and efficiently with customers. 

How Are Hollingsworth & Vose Handling the COVID-19 Pandemic?

We stepped up when COVID-19 struck the world, and our main focus became providing the filtration media for respirators, ventilators, medical wear, and COVID-19 testing materials.

In addition to filter media, our battery separators supported medical equipment and backup power sources for overtaxed emergency vehicles, hospitals, and other healthcare facilities.

According to Ayer, ”Before COVID-19, the industry was in a pretty good place. There was a wide range of interesting markets — lots of demand for increased performance requirements that really kept us not only busy but continually innovating, as well.”

As Ayer thought back to the start of the pandemic, he talked more about the challenges and adaptations the company faced: 

  • Overcoming capacity constraints 
  • Adapting and shifting focus to “people protection”
  • Providing emergency vehicles, hospitals, and other health facilities with battery separators for backup power sources

Ayer is also looking ahead to the future of H&V. He believes filtration is going to play a huge part in the future of vaccines, which require the microfiltration of liquids and pharmaceutical cleanrooms to eliminate air contaminants. 

Further, as government regulations and consumer expectations lean toward improved Indoor Air Quality (IAQ), our global environmental efforts for clean energy, air, and water will intensify. 

Important Market Segments for Filtration in 2022

As far as filtration in 2022, Ayer believes the demand for filtration media will continue to increase as the public realizes the importance of sustainability and emission reduction. Government regulations and corporate air quality policies will expedite the demand for green buildings with sustainable, healthy spaces that adhere to LEED standards.

Additionally, cabin air filtration will play a huge part in the transportation sector as we move toward more energy-efficient vehicles, such as hybrids and EVs. Ayer predicts, ”The demand for filtration in the future may evolve, but it’s not going away.”

Hollingsworth & Vose Continues Its Innovations Toward Sustainable, Clean Filtration Solutions

Hollingsworth & Vose is a family-run company and global leader in the development of sustainable filtration media. As Ayer proudly said, ”We won’t stray from our mission of creating a cleaner, healthier, more sustainable world.”
