About this product

For Potentially Higher Dirt Loads where Low Resistance and Cleanability are Critical, Choose the Model IN Washable Electrostatic Air Filter

Model IN electrostatic air filter will outperform and outlast a metal mesh panel filter in many applications. Upgrade to the stainless steel frame to use in wet, marine environments where mold and bacteria can be a concern.
Accumulator Chamber provides triple-action filtration

The IN washable electrostatic air filter for commercial HVAC air handling systems contains multiple layers of custom woven electrostatic polypropylene media with expanded wire support on both front and back. Its durable construction allows high-velocity air to be pushed through limited filtering surface areas, often found in older HVAC systems.

The 1-inch and 2-inch models feature the exclusive Accumulator Chamber. By using a unitized filter bank design, multiple layers of media assembled in a steel frame provide a distinct separation to create a triple-action filtration system. The pre-filter/after-filter assembly promotes free airflow while resisting face loading. Excess particles sweep through the pre-filter. Cross-currents within the chamber cause further agglomeration and settlement until the filter is rinsed clean. The outer frame contains strategically placed drain holes for thorough cleaning.

IN Electrostatic Air Filter Features

  • The standard frame constructed of galvanized steel. Stainless steel and aluminum frames are also available for an upcharge.
  • A stainless steel frame is recommended for caustic or corrosive environments.
  • Multiple layers of electrostatic polypropylene media with wire reinforcement.
  • Exclusive ACCUMULATOR CHAMBER® design for maximum performance.
  • FDA approved materials 
  • Drain holes positioned for easy cleaning

Best for

The Model IN is ideal for:

  • Commercial office buildings
  • Manufacturing facilities
  • Warehouses and distribution centers
  • Schools and universities
  • Healthcare facilities (non-critical areas)
  • Cigar lounges and hospitality spaces
  • High-dirt or high-velocity HVAC systems
  • Facilities with limited filter surface area

If your system pushes large volumes of air and standard filters clog quickly, Model IN is built to perform.

Installation tips

Quick, standard filter swap.

  1. Turn off HVAC system before installation.
  2. Confirm correct size and thickness.
  3. Insert into existing filter rack or housing.
  4. Ensure proper airflow direction if marked.
  5. Restore power and verify proper seating.

Maintenance Tip:
Wash with mild detergent and low-pressure water. Allow to fully dry before reinstalling. Cleaning frequency depends on dirt load and system runtime.

Frequently asked questions

How often should the Model IN filter be cleaned?

Cleaning frequency depends on environment and airflow. High-dust facilities may require monthly cleaning; lighter-duty spaces may extend intervals.

Is this filter MERV rated?

This model is rated by average arrestance efficiency (78%).

Can it replace disposable pleated filters?

Yes, in many commercial and industrial HVAC systems where washable electrostatic filtration is appropriate.

Does it reduce airflow?

Initial airflow resistance is only 0.11" w.g., supporting strong system airflow.

How long does the filter last?

With proper maintenance, the filter is backed by a 5-year warranty.

Is this suitable for healthcare?

It can be used in non-critical healthcare areas. For critical environments, confirm filtration requirements with your engineer.
