Designed for high performance under both normal and difficult operating conditions, VariCel II filters are appropriate for general HVAC and applications operating with variable air volume, turbulent airflow, and high humidity. The combination of durable construction and high efficiency also makes VariCel II filters ideal for specialized systems, such as diffusion filters in paint booths and prefilters in cleanrooms.
Heavy Duty Construction
High Performance in Tough Operating Conditions The frame is made with a 2-piece die cut contructed from high wet-strength beverage board. Two mating die cut boxes are bonded together, forming a double wall around the perimeter of the filter. The mini-pleat media pack is bonded inside the double wall. The double-walled frame prevents leakage and increases rigidity.
The slim-line design of the VariCel II filters provides minimum resistance and maximum dust loading capacity while lowering operating costs. Rows of adhesive beads are used to maintain even pleat spacing and provide maximum airflow with minimal resistance. The consistent pleat spacing of the media allows higher dust holding capacity and full use of the entire depth of the media.
Increases Dust Holding Capacity VariCel II filters use microglass paper media with a water repellent binder. The fibers are formed with dual-density construction, consisting of coarser fibers on the air entering side and finer fibers on the air leaving side. This design allows for collection of particulate throughout the full thickness of the media, substantially increasing dust holding capacity. The media is water repellent and can withstand intermittent exposure to water without affecting performance.

Compatible with Furnace, AC and HVAC Systems
The terms furnace filter and air conditioner (AC) filter. Are there really two different filters for the heating, ventilation, and air conditioning (HVAC) system in your home, or are they referring to the same filter? The answer—they are the same! Often times it depends on what part of the county you are in for the term you hear more often.

Frequently Asked Questions
Minimum Efficiency Reporting Value (MERV) is a filter industry standard system that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter. Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.
Choosing the correctly sized air filter is important in order to keep air clean in your home. An improperly sized filter may have limited performance. Determining the proper air filter size can be confusing, since filter packages generally display two sets of dimensions. It is important to understand that these dimension sets are the nominal and actual dimensions of the filter, and differences between the two.
The best place to start is our filter search page that can be found at the following link or at the top of every page.
You can search by filter size, part number, model and more.
Tips: When using our search option to locate your filter size especially for Exact Filters® enter the exact size needed in the format shown here.
No spaces, fractions only 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8.
Most often there will be an arrow on the side of the filter which will indicate which way to insert the filter. The arrow will show which direction the air is to travel through the filter. If there is no arrow the filter can be installed in both directions.
Remember your filter is designed to protect your system first and foremost. Air should be traveling through the filter before your blower and system.
Furnace, AC and HVAC filters are most often measured in inches. A nominal measurement would be a rounded number like 20x25x1, rounded up to the nearest inch. These filters if measured with a tape measure would likely be closer to 19 ½" x 24 ½" x ¾" which would be the actual true exact size.
