A+ 2000® Permanent Air Filter
The A+ 2000 is truly a quality product, build to last a lifetime. Unlike some permanent air filters, the A+ 2000 used NO FOAM that may clog, degrade and restrict air flow, so it can provide a lifetime of dependable service. And there are not metal parts that could lead to corrosion or oxidation within the filter.
A+ 2000 permanent Air Filters are designed to provide a balance between adequate air flow and filtration. According to NAFA, resistance to air flow, called pressure drop, causes your unit to work harder, resulting in greater energy consumption and possible damage to your unit. In selecting an air filter, the most important consideration is the ability to remove from an air stream the greatest number of dust particles whose size is of most concern.
How slow or fast an air filter reaches its capacity greatly affects resistance, because a filter's resistance will increase as it captures particles. That's why it's important to have a filter with a good balance of resistance to air flow and adequate filtering capabilities.
