Replacement Filters Features and Benefits

UL 900 Certified for Fire Safety

HEPA and ULPA filters are UL certified for UL 900 to meet local and state fire safety requirements for most applications. The standard covers requirements and tests for allowable combustibility and amount of smoke generated.

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.

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

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

HEPA Filters Prevent Infection
Watch Terra's Portable HEPA Filtration System Video

HEPA filters capture and mitigate airborne particles that can cause infections. HEPA Filters Prevent Infection HEPA and ULPA filters capture and mitigate airborne particles, as well as pathogens including Rhinoviruses, Influenza, SARS-CoV-2, and RSV. Filters also combat aerosolized bacteria like C. Difficile, a prevalent cause of hospital-acquired infections.

Terra's in stock portable HEPA filtration systems provide high quality and medical grade air filtration for your ambient environment. Watch Terra's Portable HEPA Filtration System Video The mobile/ self contained filtration system converts to any room to a negative pressure isolation room which then makes it well suited for medical clinics, schools, waiting rooms and other confined areas.
