What is the difference between a pleated filter & a fiberglass filter?



Pleated Filters: 

Pros:

  • Better indoor air quality based on the MERV (Minimum Efficiency Reporting Value) rating. Check which filter is recommended for your system.
  • May remove particles associated with allergy causing pollutants
  • May remove particles associated with sickness such as mold spores and bacteria

Cons:

  • May restrict air flow which leads to inefficient operation and damages
  • Typically needs to be replaced every 1-3 months
  • Approximately 3X more costly than a fiberglass filter
