4.6 High Efficiency Air filter
A high efficiency air filter is available for the Ultra-Aire . This filter is
rated 90%-95% efficient by ASHRAE Dust Spot Test Method 52-76.
This filter is much more efficient than the standard air filter and is
able to catch much smaller particles that can aggravate allergies.
The high efficiency air filter is 4 inches thick and should be
installed in the filter enclosure directly below the standard air filter.
The standard air filter will act as a pre-filter for the high efficiency
air filter and will prolong the life of the high efficiency air filter.
