Filter efficiency in businesses: The critical need to improve air quality

WLF Filter 2000 has around 300 customers coming from a variety of industries. Since the worldwide coronavirus pandemic, owner Marc Wilhelm has observed a significant shift in demand and purchasing behaviour. Factors such as reducing the risk of infection and enhancing working conditions through clean air are becoming bigger priorities. Improving indoor air quality is now essential not just for sectors with stringent hygiene standards, such as healthcare, pharmaceuticals, or the food industry, but for all companies aiming to meet the needs of their customers and employees.

Energy-efficient filters for more sustainable air filtration

The rising adoption of air filter systems, coupled with escalating energy prices, is posing significant new challenges for companies, especially in terms of increased energy consumption. This impact is evident not only in terms of the increased carbon footprint but also the greater financial costs. This situation is driving the move towards energy-efficient filtration technologies that can reduce costs and the environmental impact.

Energy classification in air filtration: A+ filters by MANN+HUMMEL

"More and more customers of WLF Filter 2000 are opting for energy-saving filter solutions to reduce the energy consumption of their systems and installations. The proportion of A+ filters sold has almost doubled in recent years," reports Marc Wilhelm.

The decision to opt for high-efficiency, energy-saving air filters is motivated not just for economic reasons, but also for the ecological benefits they provide. Companies that have embraced this approach are convinced of the undeniable benefits of using A+ filters:

  • Up to 41 % energy savings compared to conventional standard filters
  • High cost savings aligned with greatly improved performance
  • Positive impact on the environment and climate due to significantly reduced energy consumption
  • Increased filter service life and performance
  • Beneficial contribution to environmental and climate protection, as well as future-proofing systems in readiness for upcoming environmental regulations

"Probably the biggest advantage of switching to energy-saving filters is the significant cost savings that can be achieved. An A+ filter saves up to 41 percent energy compared to a conventional standard filter. Customers are simply delighted with the performance and longevity of the energy-saving filters."
