The A+2000 permanent electrostatic filter are truly a quality product, built-to last a lifetime. Unlike some permanent air filters, the A+2000 uses no foam that may clog, degrade and restrict air flow, so it can provide a lifetime of dependable service. And there are no metal parts that could lead to corrosion or oxidation within the filter. Cleans easily and effectively no oil sprays or expensive cleaners required. The A+2000 permanent electrostatic filters are designed to provide a balance between adequate airflow 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 airflow and adequate filtering capabilities. The secret behind the A+2000 superior performance is its patented stage loading/peak and valley design. Instead of face loading (particles captured on the outer surface of the filter) the A+2000 uses stage loading, with each stage capturing progressively smaller particles inside the filter. This design enables the A+2000 to maintain its performance over the years.
