    Droplet vs Aerosols: Evaluating Respiratory Virus Transmission

    Most respiratory infections are caused by respiratory viruses, a significant cause of morbidity and mortality for humans. Respiratory viruses are transmitted through by four major transmission modes: 

    • direct (physical) contact
    • indirect contact (fomite)
    • (large) droplets
    • (fine) aerosols

  3. Medical-Grade HEPA Filter Solutions for Hospitals & Cleanrooms

    Medical-Grade HEPA Filter Solutions for Hospitals & Cleanrooms

    Medical-grade filters and medical filtration systems include a HEPA filtration design that is designed to yield breathable, non-contaminated air. Unlike industrial or equipment-based filters for vacuums and equipment pumps, medical-grade filters are designed to reintroduce and recirculate extremely clean air back into the environment. Importantly, medical-grade filters must also prevent contamination that is introduced from the filter itself. Thus medical-grade filters do not use fiberglass filter media, which can introduce microscopic fiberglass particles into the air stream.

  4. How Do I Calculate Cleanroom Fan Filter Ceiling Coverage?

    How Do I Calculate Cleanroom Fan Filter Ceiling Coverage?

    Cleanroom fan filter coverage is an important consideration when designing and constructing a cleanroom. Fan filter coverage is largely determined by cleanroom air flow requirements. A room with faster air change rates requires more airflow, thus will also require additional fan filter units to achieve the desired air flow velocity and room air change rates.

    Methods of Cleanroom Air Flow Calibration - Tips for Balancing and Calibration

    cleanroom is an environment that must maintain a specific concentration of airborne particles per cubic meter. Cleanrooms are usually defined by the maximum allowable concentration of airborne particles in the room. To achieve and maintain a specific cleanliness level, the room is supplied with a continuous supply of HEPA filtered air.

    Terra Cleanroom Filter Replacements for Cleanrooms and Controlled Environments

    When searching for "True" HEPA filters, H13, or IEST rated HEPA filters, not all classifications of HEPA filters are created equal. There are numerous groups and classifications that further distill HEPA performance ratings into more specific performance categories.

    Terra’s HEPA and ULPA filters are specially designed for use in cleanrooms, labs, and precision assembly areas. They come in a wide range of sizes for use in Terra work stations, cleanrooms, and many other applications. They can also be used as final filtration in standalone purification systems.

  9. Air Quality and Surface Decontamination - How HEPA Filters, UVC Lights, and Portable HEPA Systems Reduce COVID-19 Contamination

    Air Quality and Surface Decontamination - How HEPA Filters, UVC Lights, and Portable HEPA Systems Reduce COVID-19 Contamination

    Traditionally, HEPA fan filter units and far-UVC disinfection lights were most common for environments requiring critical air quality control such as cleanrooms, hospitals, pharmaceutical processes, and healthcare facilities.

    The resurgence of global pandemics such as COVID-19 places abrupt demand on commercially deployable HEPA air filtration systems and UV disinfection technology. UV decontamination lights and HEPA filtration are known to be rapidly effective for capturing and eradicating a wide range of surface and airborne based contamination, including SARS-CoV-2 and other respiratory viruses.

    This post outlines various product features, methodologies, and configuration options for mobile and portable HEPA filtration systems. Additionally, this post covers additional solutions for integrated and standalone UV torches, far UV lamps, UV wands, and UV integrated

  10. Save Money with Room-side Replaceable Fan Filter Units

    Save Money with Room-side Replaceable Fan Filter Units

    A cleanroom fan filter unit (FFU) uses HEPA filtration to protect products and personnel inside the cleanroom from unwanted particles and germs. The HEPA filter (or ULPA filter) in the FFU is constructed of delicate tightly woven fibers to catch sub-micron particles. In a typical cleanroom, the fan powered hepa filter mounts on top of the ceiling grid and scrubs air clean as the motor pulls air from outside the cleanroom, pushes it through the HEPA filter and into the cleanroom.The downward top-to-bottom flow of air into the cleanroom provides laminar airflow - a single pass unidirectional flow of air--starting from the ceiling and exiting near the floor--to help flush out other contaminants that may be introduced inside the cleanroom. The clean filtered air being pushed
