Brief Comparison Between Paper And Polyester-Based Industrial Filters

Paper and polyester are the two most commonly used filter elements in industrial air filters. But what are some major differences between the two? In this blog, Dynamic Filtration Ltd., a major manufacturer of industrial filters in Waterloo, Ontario, explores the major differences between the two filter elements in detail.

 

 

What Are The Major Differences Between Paper And Polyester-Based Industrial Filters?

 

Filtration Efficiency

 

Paper filter elements are mainly designed to capture larger particles in the air. They have a typical MERV rating of 8-10. Polyester, on the other hand, is more adept at capturing smaller airborne particles. Hence, the two vary in terms of the type of particles they can capture.

 

Airflow And Resistance

 

Paper-based air filters typically have a tighter weave. While this is great from a filtration standpoint, it can reduce the overall airflow. Hence, when used in HVAC systems, it can place a slight strain on the system.

 

Polyester-based air filters, on the other hand, have a looser weave without compromising filtration. Thus, they can trap microscopic particles while maintaining decent airflow.

 

Durability

 

Paper is not a great fit for moist environments, as it can deteriorate

 

Polyester-based industrial filters are better equipped to handle moisture and damp environments. Hence, they are considered more durable than paper filter elements.

 

Maintenance

 

Paper filter elements do not require maintenance. They are designed to be replaced once they are worn out.

 

Polyester elements last longer and thus can be cleaned multiple times. However, there are also some non-washable versions of polyester filters.

 

Cost-Effective

 

In terms of cost-effectiveness, paper-based industrial filters are highly cost-effective, even when they are meant to be replaced regularly.

 

Polyester, by comparison, has a higher initial cost. However, they do offer some benefits with their durability and reusability.

 

 

Conclusion

 

To summarize, paper and polyester-based air filters have very different features. Selection will depend on examining the operating conditions and applications.

FAQs:

 

What is cellulose used in paper industrial filters?

 

Cellulose is a type of filter element that uses compressed wood pulp and cotton fibres to create a paper-like consistency.

 

Are paper industrial filters reusable?

 

No, paper industrial filters are designed for single-use and need to be disposed of after a short time.
