Manufacturing of Industrial Filters In Waterloo, Ontario

Industrial filters are known for their efficiency, robustness and overall quality. Some popular options are pleated air filters and fiberglass filters. In fact, the two are often compared with one another in terms of features. This comparison is irrespective of whether it is a custom filter or OEM-manufactured. So here’s a look at how pleated air filters fare in comparison to their fiberglass counterparts over these 5 features.

 

Pleated Air Filters Versus Fiberglass Air Filters

 

Overall Filtration

 

When it comes to the effectiveness of the filtration, pleated air filters fare better than fiberglass. This is because these filters can trap smaller particles easily, leading to a significant improvement in air quality. However, fiberglass is only optimal for trapping larger particles.

 

MERV Rating

 

MERV rating is another metric to quantify the filtration efficiency. The higher the MERV rating, the better the filtration efficiency. By this metric, pleated air filters are still superior, as they have a MERV rating of 8-13. By comparison, fiberglass air filters only have a MERV rating of around 2-3. 

 

Durability

 

In terms of durability and lifespan, pleated air filters last longer than fiberglass filters. On average, the former lasts at least 3 months or longer, whereas the latter lasts a month at best. 

 

Cost Effectiveness

 

When it comes to the initial cost of investment, fiberglass air filters might seem like a better choice. However, since pleated air filters last longer and require fewer replacements, they are more cost-effective in the long run.

 

Airflow

 

This is the only parameter where fiberglass filters fare better than pleated air filters. Due to their pleated design, the filters add more resistance to airflow, which can lead to higher energy bills in older HVAC systems. However, since fiberglass filters can’t trap small particles, there has to be a tradeoff between airflow and filtration efficiency.
