3 Cases Where Pleated Air Filters Restrict Airflow

Pleated air filters are often thought to be a bad match for HVAC systems where airflow is critical. However, nothing is further from the truth. Pleated air filters, like most industrial filters, are excellent for such applications. There are 3 cases where they are detrimental to airflow in commercial HVAC systems. Dynamic Filtration Ltd., a leading manufacturer of industrial filters and custom filters in Waterloo, Ontario, explores these 3 cases in this blog.

 

 

When Are Pleated Air Filters Detrimental For Steady Airflow?

 

Wrong MERV Rating

 

MERV rating is an important factor to consider for pleated air filters. Choosing a filter with a higher MERV than is required for the application can lead to airflow restriction. For instance, opting for pleated air filters with a MERV rating of 16 or above is unsuitable for most commercial HVAC systems. However, this is a selection issue, not a filter issue.

 

Neglected Maintenance Schedules

 

This is obvious but equally important. Pleated air filters must be maintained or replaced on a regular schedule for optimal performance. Neglecting to do so can lead to airflow restrictions, as the presence of dust and contaminants will clog the industrial filter.

 

Mismatched Filter Sizes

 

Mismatched filter sizes can ruin the performance of even the best pleated air filters. For instance, if the filter is not fitted snugly in the housing, then it can leave gaps where unfiltered air can pass through. Similarly, if the filter is not sealed properly due to improper sizing, airflow problems can occur. 

 

 

Conclusion

 

Overall, the problem of airflow with pleated air filters is often due to improper filter selection rather than the feature of the filter itself.

FAQs:

 

What are the benefits of pleated air filters for commercial HVAC systems?

 

The benefits of pleated air filters for commercial HVAC systems include better particle capture, longer lifespan of components, and improved air quality.

 

What does the MERV rating display in pleated air filters?

 

MERV rating explains the measure of how well the filter traps tiny particles, usually in the size range of 1 to 10 microns.
