ciency of 99% at an initial resistance of 0.10 to 0.50 inches of static pressure.
High efficiency particulate air (HEPA) filters are even more efficient than those just described
and are cost effective for the home cultivator. They screen out particulates down to 0.1 -0.3 microns
with a rated 99.96% to 99.99% efficiency and have a resistance of .75-1 .00 inches of static pressure. HEPA filters are made of a variety of materials, depending on their intended application. Most
HEPA filters operate in environments of up to 80% humidity without disintegration. Special "waterproof" filters operable in 1 00% humidify environments can also be purchased at little or no extra
expense. These "waterproof" filters are especially appropriate for use with systems that push recirculated air through the filter. This type of system is illustrated in Figure 77. To protect the filters and
prolong their usefulness, a one inch prefilter of open celled foam or fiberglass (of the furnace type) is
installed to remove large particulates.

Exhaust Vents
Exhaust vents are designed to relieve overpressure within the growing room caused by the introduction of fresh air. Without an exit for the air, a back pressure is created that increases resistance
and reduces the CFM of the fan. Small rooms operating with low fresh air requirements can forgo
special exhaust vents and allow the air to escape around the seals of the room entrance, in effect

creating a positive pressure environment. Positive pressure within a room can also be created by
