The secret behind the A+2000‰۪s custom air filters performance is the patented stage loading/peak and valley design

åÊWe look forward to delivering our American-made

The "Practical Pleat" contains over 500% greater surface area than a MERV 10 one-inch pleat

such as dust

and long service life which reduces HVAC equipment maintenance and energy costs

Because we specialize in custom air filters

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

if not you can measure it or check the HVAC unit and the owner‰۪s manual

some just refer to them as electrostatic filters

One way to overcome this problem is to increase the surface area of the filter media

the A+2000 uses no foam that may clog
