CELLULOSE & POLYESTER BLEND
Most cellulose and polyester blends are comprised of 80% cellulose and 20% polyester. They are commonly referred to as 80/20 blends. 80/20 media is most often used for dryer dusts with larger particulate due to its MERV (Minimum Efficiency Reporting Value) 11 rating. Its rating makes this filter a functional choice for large particulate, it may allow the finest and most hazardous dusts to pass through. Learn more about MERV ratings here.
The polyester portion of this media makes for a filter that is more durable than those that are composed of 100% cellulose. The polyester also makes the filter more resistant to humidity.
80/20 is also available with a fire retardant material suitable for applications with a risk of sparks or other fire hazards. If the FR upgrade is not available on your filter’s product page, give us a call or reach out to us in the chat box.
