In 2023, a global financial services firm in London’s Financial District replaced its disposable filters with K&N washable reusable filters across its 10-story headquarters. The facility team, already committed to sustainability with intiatives like a rooftop garden using recycled water, aimed to further that commitment as they participated in a pilot of K&n’s potentially transformative product: high-flowing, washable reusable HVAC filters. The client was able to demonstrate significant improvement in differential pressure while also demonstrating a slowing of the build-up of dP over the legacy disposable filters. Managers were able to extend the changeout cycle from roughly 5 months to washing every 9 months. Over all the operation is more sustainable, requiring fewer deliveries and fewer waste hauls because of the change.
