WhisperFlow® Portable HEPA Filtration System, High Capacity
Product Details
  • Available ISO Ratings: ISO 5, ISO 6, ISO 7, ISO 8
  • HEPA filters help capture many bacteria and viruses such as COVID-19 to reduce risk of infection
  • Portable isolation room filtration system suitable for negative pressure or recirculation
  • Medical grade air filtration system quickly converts any room to a negative pressure isolation room
  • Mobile, self-contained, high capacity air purifier with small footprint easily rolls between rooms
  • Clean Air Delivery Rate (CADR) of 800 CFM replaces air 5x per hr in a room 1,000 sqft x 9 ft high
  • In addition to wearing face masks and staying at least six feet away from other people, good air circulation and ventilation inside buildings will reduce the spread of COVID-19 in aerosols.
  • Medical grade air filter system is ideal for clinics, waiting rooms, hospital emergency rooms, schools, court houses, and other confined areas without access to open windows for outdoor air circulation.
  • High-capacity design features a large 2' x 4' HEPA filter, allows longer operation with fewer filter replacements.
  • Mobile filtration system features powerful blower to supply a Clean Air Delivery Rate (CADR) of 800 CFM to minimize the spread of airborne diseases.
  • One way to measure ventilation is to determine how often the air in a space is completely replaced. This is called Air Changes per Hour (ACH). In a 900 sq.ft. (30-foot by 30-foot by 9-foot high) room with 25 people in it, the air can be replaced roughly every 10 minutes, which equals an ACH of 6. Higher ACH lowers the risk of disease spreading through the air.
  • Mobile hospital air purification system easily configures for recirculation or negative pressure:
  • For recirculation: room air and airborne contaminants are drawn through intake grille at the bottom, and purified air is discharged from the exhaust grille at the top to generate a sweeping, low-to high air circulation pattern to optimize clean breathing zone for patient and staff.
  • For negative pressure: simply connect flexible ducting to the top exhaust to direct exhaust through a window or wall. The system creates a negative pressure environment isolation room, suitable for use with patients known or suspected of having infectious diseases.
  • Quiet, low vibration HEPA filter system; only 43 dBA measured 30 in. from unit minimizes distracting background noises.
  • High Efficiency Particulate Air (HEPA) filter: 99.99% efficient at 0.3µm particle diameter
  • Uses a lightweight, forward-curved fan powered by a 120V 60Hz motor
  • Includes four swivel casters
  • Variable speed dial simplifies air balancing
  • Filters are leak tested in accordance with IEST standards and meet UL 900
  • All filter sales are final; returns for this item cannot be accepted

Features and Benefits

Room Coverage and Air Changes per Hour

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.

Protect Against Contaminants and Pathogens

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

Portable Isolation Room Filtration System

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.

Easily Converts from Recirculation to Negative Pressure Isolation

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.

Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity

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.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

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).
