Product Description

PERMAFILT Pre-Filter is designed to last for years. Once installed, this Pre-Filter can be easily maintained by occasional vacuuming from outside the perforated steel housing of the Austin Air unit. This procedure keeps the Permafilt Pre-Filter clean and increases the life expectancy up to 2 or 3 years, eliminating costly quarterly filter changes. The HealthMate Pre-Filter: Standards is a replacement pre-filter for all Standard Austin Air models, and is available in Black or White. The HealthMate Pre-Filter: Standards works to trap large dust particles, and can effectively filter a room between 150-1500 square feet. The HealthMate Pre-Filter: Standards is available in Black and White. NOTE: The HealthMate Pre-Filter: Standards can be seen from the exterior of your air purifier. Be sure to carefully select the HealthMate Pre-Filter: Standards to match the color of your air purifier. The white HealthMate Pre-Filter: Standards can be used for both white and sandstone air purifiers. The black HealthMate Pre-Filter: Standards can be used for the black and silver air purifiers.
