Keeping the air you breathe clean and safe during flight is one of the most foundational layers of protection Delta aims to provide to our customers and employees. Just as we have focused on ensuring clean air onboard by replacing our industrial-grade HEPA filters twice as often as recommended, we are also committed to ensuring clean air on the ground.

By mid-September, Delta will replace the current air filtering systems that pump outside air into our jetbridges and parked aircraft with LEED Platinum MERV14 filters that will result in a more than 40% reduction in air particles* and cleaner air in those spaces during boarding and deplaning.
