Cellulose and 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, but it may allow the finest and most hazardous dusts to pass through. Learn more about MERV ratings here.

The polyester portion of cellulose and polyester blends 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, which is one reason cellulose and polyester blends are commonly selected for demanding environments.

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.

There are filters available in every size that are a better choice for fine dusts. This media is called nanofiber. Click here to review further information on this media. Nanofiber may also have double the lifespan of a typical 80/20 media, and almost all users see improved filter life after switching.

This cellulose and polyester blend is a great choice for:

Wood
Paper

Aggregate
Mining

Textile
Cement

An 80/20 blend consists of approximately 80% cellulose and 20% polyester, combining cost-effective filtration with improved durability and moisture resistance.

This media typically carries a MERV 11 rating, making it suitable for capturing larger particulate while allowing finer dust to pass through.

It is ideal for dry dust applications with larger particulate such as wood, paper, aggregate, mining, textile, and cement environments.

The polyester component increases strength and durability while also improving resistance to humidity, making it suitable for more demanding operating conditions.

No. While effective for larger particles, finer and more hazardous dusts may pass through. For those applications, higher-efficiency media such as nanofiber is recommended.

Yes. This media can be treated with a fire-retardant coating for applications where sparks or fire risks are present.
