When choosing a filter, consider the efficiency of the filter with regards to your system and the overall filter performance . . .
- Is it pleated? A pleated filter provides additional surface area on which particles can be trapped.
- Is it electrostatically charged? Filters with electrostatic charging can attract and capture particles that other filters can miss.
- What type of particulates does it capture?
- What is the filter's efficiency?
- What is its MERV rating? A larger MERV (Minimum Efficiency Reporting Value) number means better filtration. (Scale for a MERV Rating is 1 to 16)
- How many air changes (jump to link to definition) per hour do you want?
HOW EFFICIENT ARE THESE FILTERS?
- Flat Throwaway:
- Usually made of fiberglass or polyester and is typically the least efficient filter with a MERV rating range of 0 - 1.
- Pleated Throwaway:
- Usually made of cotton polyester and has a MERV rating range of 3 - 6.
- Electrostatic Pleated:
- Has a higher efficiency and is better at filtering because it holds a charge that attracts allergens, mold, etc. The MERV rating for these filters is around 8 - 11.
- Deep Pleated:
- Provides the highest efficiency and uses microglass to enhance its effectiveness. The MERV rating range for these filters is 8 - 10.
