High-Capacity WhisperFlow® Portable HEPA Filtration System

Filters 9ft high 300 sq. ft. with 17.8 air changes per hour, or once every 3.4 minutes. Filters 500 sq. ft. with 10.7 air changes per hour. Filters 800 sq. ft. with 6.7 air changes per hour. Filters 1,600 sq. ft. with 3.3 air changes per hour.

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures

Use this mobile medical grade air filtration system to recirculate HEPA-filtered air in confined areas or quickly convert any room to a negative pressure isolation room.

Portable isolation room filtration system easily configures for recirculation or safe exhaust. In exhaust mode, a flange adapter attaches to the top of the unit for connection to ducting. The ducting then re-directs filtered air outside the room.

Unlike other manufacturers, Terra’s FFUs include a unique perforated panel beneath the filter, acting as a shower head, to guarantee filter protection and laminar air flow uniformity, which prevents localized air swirling, particle build-up and turbulence.

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
