Partnering with a leading climbing gym and fitness center to reduce annual filter waste by 15 tons

THE FILTRATION CHALLENGE AT BOULDERING PROJECT

The Bouldering Project, headquartered in Seattle with 12 locations nationwide, is a nationally recognized indoor bouldering gym where climbing enthusiasts go to climb, train, exercise, and practice yoga. Their facilities are typically located in densely populated urban environments, with high occupancy at peak hours creating a significant amount of chalk dust that must be filtered efficiently and effectively to maintain a safe and pleasant experience for climbers.

At Bouldering Project’s small facilities, the number of filters needed per replacement cycle could be as few as 6 in the RTU for the building. In contrast, larger facilities, like the Springdale gym in Austin, 11 RTU’s continuously run to keep the building cool and over 60 filters keep customers breathing easy with clean air.

Bouldering Project’s filtration challenge is unique in that the volume of particulate they are filtering is massive — enough to be measured in kilograms per day — and the frequency with which they change filters to maintain an enjoyable experience for members is very high — up to 2 times a week in the driest and dustiest times of year.

“Sustainability has three components: Economic, Environmental and Social — This makes sense for us on the Economic side because we’ll see payback in less than 12 months. On the Environmental front, we are removing 15 tons of waste from the landfill every year. And on the social side, we are helping create a better experience for the members of the community that use our space. Ticks all the boxes”

PROBLEM:

Until 2024, the Bouldering Project filtered their air the same as any other company: by purchasing and replacing legacy single-use filters and disposing of them in the landfill. The process racked up sizeable operational expenses as Bouldering Project continuously purchased filters to replace the old ones. In fact, in 2023 Bouldering Project purchased and disposed of over 14,000 filters at an average cost of about $10 per filter, generating about 15 tons of mass to landfill and about $150,000 off their bottom line.

As a company that prides itself as being a responsible participant in the climbing community, Bouldering Project recognized that their large contribution of mass to the landfill was unacceptable. Bouldering Project prides itself on it’s superior gym experience, continuously investing to improve the overall gym experience at their facilities — $150,000 per year is money that would be well spent to better the experience and facilities and provide more community support.

SOLUTION

K&N’s High-Flow Washable Filters are and were the perfect solution to help reduce Bouldering Project’s operational expenses and minimize their impact to the landfill. Starting with a small PILOT of 6 filters, in one air handler at a single facility, K&N was able to demonstrate equal/or better filtration with their washable reusable product.

Bouldering Project facility managers integrated the filter washing process into their existing workflows and the PILOT yielded immediate savings on filter purchases at the facility. The PILOT expanded to a larger facility with consistent results as the pilot scaled and in the spring of 2024 Bouldering Project rolled out K&N Washable HVAC filters to all their facilities nationwide.

The keys to success

  • Extended filter life and lower maintenance requirements
  • Durable performance under heavy air and debris loads
  • Simplified changeout process, freeing up city maintenance teams
  • Tangible financial and environmental ROI

McDonald’s Case Study

McDonald’s Case Study

MCDONALD’S STREAMLINES OPERATIONS AND CUTS COSTS WITH K&N REUSABLE FILTERS

In 2024, McDonald’s adopted the K&N Washable, Reusable HVAC Filters in select high-volume restaurant locations within the U.S., aiming to increase operational efficiency, reduce maintenance labor and support sustainability goals. Known for efficiency and consistency across thousands of locations, McDonald’s facility teams sought a filtration solution that aligned with both their cost-saving initiatives and maintenance goals.

By transitioning from traditional disposable filters to K&N’s high-flow, washable technology, McDonald’s saw immediate operational benefits. Labor costs decreased significantly as maintenance teams were able to extend filter change-out cycles from every two weeks to once a month. The simplified maintenance process allowed teams to reallocate labor to other high- priority areas, while the reduced volume of discarded filters contributed to the company’s broader sustainability efforts. The shift also yielded a clear financial return, with McDonald’s realizing full ROI in under nine months.

87% Waste Diverted: Animation Studio’s Path to Zero-Waste Filtration

87% Waste Diverted: Animation Studio’s Path to Zero-Waste Filtration

A CREATIVE CAMPUS CONTINUES ITS DRIVE TOWARD ZERO WASTE WITH K&N FILTERS

A leading animation studio’s collaboration with K&N Engineering exemplifies how thoughtful innovation can drive meaningful environmental and economic benefits. By replacing disposable HVAC filters with durable, washable alternatives, the studio has taken a significant step toward achieving its sustainability objectives. This particular case study serves as a model for other organizations seeking to enhance their environmental stewardship while also realizing cost efficiencies.

OVERVIEW

Recognized worldwide for its iconic films, the studio also nurtures a culture that emphasizes innovation, diversity, and environmental stewardship. It is committed to sustainability, integrating eco-friendly practices into both operations and storytelling. In recent years, the studio has intensified its efforts to achieve Zero Waste to Landfill certification, a process that requires diverting at least 90% of waste from landfills. As of 2025, it has successfully diverted over 87% of its campus-wide waste, positioning itself as a leader in corporate sustainability.

CHALLENGE

Despite significant progress in waste diversion, the studio identified an area with substantial environmental impact: disposable HVAC filters. These filters, typically replaced quarterly, contributed approximately 2,800 pounds of waste annually. The operations team recognized an opportunity to further reduce landfill contributions by adopting a more sustainable solution.

SOLUTION

The studio partnered with K&N Engineering, a company renowned for its high-performance, washable, and reusable filters. K&N’s filters are designed for longevity and can be cleaned and reused for years, significantly reducing waste and the frequency of replacements. The pilot program involved replacing traditional disposable HVAC filters across the studio’s campus with K&N’s washable filters. This initiative aligned with their sustainability goals and offered a practical solution to further minimize environmental impact.

ENVIRONMENTAL IMPACT

The adoption of K&N washable filters enabled the studio to divert an additional 1% of its waste from landfills annually, contributing to its ongoing journey toward Zero Waste to Landfill certification. This initiative underscores the studio’s commitment to environmental responsibility and its proactive approach to sustainability.

This initiative also led to a dramatic reduction in associated carbon emissions. By eliminating the need for continuous delivery of disposable filters to the facility, the studio was able to reduce carbon emissions by over 98%. In real terms, this translated to the elimination of 25,410 pounds of carbon dioxide per year and 83,868 delivery miles driven over the life of the filters. This underscores their proactive approach to sustainability and its commitment to reducing its carbon footprint.

SOCIAL IMPACT

The studio has cultivated a culture where sustainability is integral to its identity. They offer internal sustainability tours and encourages employees to participate in initiatives that promote environmental stewardship. This hands-on involvement fosters a sense of pride and community among staff, reinforcing the company’s dedication to making a positive impact on the world.

The keys to success

While K&N’s washable filters require a higher initial investment compared to disposable alternatives, they offer long-term cost savings. The animation studio’s team demonstrated a payback period of less than three years on the initial investment, with expectations that the filters will remain effective for up to 10 years. This approach not only reduces waste but also leads to significant financial savings over time.
