How to Choose

There are several things to consider when selecting a permanent filter for your central air system:

  • The type of frame
  • Level of arrestance
  • Size

Frame Types

There are two rigid frames and one flexible frame to choose from. All three frames have the same quality of filtration material, but the Gold frame is the best-made, most durable. The Silver frame is slightly more economical. The FLEX frame is for special applications.

  • The ElectraGold filter has a premium quality extruded aluminum, gold anodized frame with a durable and attractive finish. The gold frame is held together by rivets at all four corners and is sturdier than the silver frame.

  • The ElectraSilver filter has a single piece, roll-formed steel frame with a durable and attractive finish.

  • The ElectraFlex flexible filters are available for applications where a rigid frame cannot be used because the filter must be bent in order to install.

Arrestance Levels

Arrestance: The arrestance of a filter reflects its ability to remove small airborne particles. Certain Air-Care permanent electrostatic filters are configured with an arrestance value of 88%, others with 94%, and FLEX frame filters with either. Since 94% arrestance provides a greater amount of particle capture, this level would normally be preferred. The 88% arrestance filters, however, may be needed when used in an older or weaker air handling system since air can move more freely through them. The difference in effectiveness is minimal.

Standard Filter Sizes

Air-Care washable filters are available in 30 standard sizes which include ElectraGold and ElectraSilver filters in 1-inch depths and ElectraFlex filters.
