exceed's microscopic nanofiber mesh keeps particles at bay.

How does it work?

Our products are manufactured using cutting-edge nanofiber technology developed and popularized by our founder, Dr. Jayesh Doshi, a researcher at the forefront of developments in electrospin technology.

During the electrospinning process, nanofibers ranging from 100 to 500 nanometers in diameter are woven together to form a microscopic mesh that is incredibly effective at filtering out pollutants. Thanks to the nanofibers, this microscopic mesh has a larger surface area to capture more small particulate matter, like dust, aerosols, pathogens, and smoke. Their nanoscopic size also reduces air flow restriction and lowers pressure drop, which lasts longer and ensures that your HVAC system is energy efficient.

Unlike standard filtration materials, our nanofibers are water and oil resistant, making them durable in tough weather conditions. 

Our nanofibers are smaller than small.

Nanofibers provide a unique benefit in air filtration because of their size. Our nanofibers are 1000 times smaller in diameter than a single human hair, and create a mesh that captures even the finest particles that usually pass through conventional air filters.

Increased airflow means more bang for your buck.

The size of exceed nanofibers is perfect for allowing air to pass through while trapping particles. The increased airflow compared to conventional filters provides a substantial savings by reducing maintenance and electricity use.

Made in a state-of-the-art, proudly American facility.

Our small business was born 22 years ago in Chattanooga, Tennessee, and has developed into a state-of-the art research facility, with testing instruments including wind tunnels, particle counters, and a SEM microscope. We are a leading provider of nanofiber products to many American institutions, including airports, schools, industrial facilities, and the United States military.

Pesky particles are small, but exceed has you covered.

Pet dander

Our beloved animal friends, including dogs, cats, rodents, and birds all shed tiny skin particles that can trigger allergies.

Mold spores

Mold can grow in many places around the home with moisture, as well as tracked in from other places.


A single particle of dust can be home to hundreds of dust mites, affecting those with asthma and allergies.

Grounded in science.

Developed in close collaboration with industry experts and scientists, our products effectively reduce many common household pollutants.

Rigorously tested.

We take pride in carefully testing our technology, both in-house and through independent, third party laboratories.

Quality manufacturing.

As independently certified by a third party, our management system meets international standards for quality products.
