Practical Pleated Air Filter (2-Pack) - 17 1/2" x 23 1/2" x 5"Yes, we even have the odd sizes! The "Practical Pleat" media is up to 28 times more effective at capturing particles than standard fiberglass panel filters. In general, the more efficient a filter is at removing particles, the greater it's resistance to airflow, and the greater the pressure drop it creates. One way to overcome this problem is to increase the surface area of the filter media. The "Practical Pleat" contains over 500% greater surface

This design enables A+2000 custom air filters to maintain performance over the years

We can make custom air filters in heights and widths ranking from 6 inches to 36 7/8 inches with increments in 8ths of an inch

And there are no metal parts that could lead to corrosion or oxidation within the filter

the A+2000 uses stage loading

We look forward to delivering our American-made

the A+2000 uses no foam that may clog

Instead of face loading (particles captured on the outer surface of the filter)

Unlike some permanent custom air filters
