    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 HEPA modules. Further, there are a number of value added considerations such as UV storage cabinets and PPE storage dispensers which improve outcomes for high-volume industries including hospitals, schools, manufacturing facilities, and police-fire-EMT services.

  2. 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 into the cleanroom also creates a positive pressure environment to help keep unwanted contaminants from drifting inside the cleanroom.

  3. FFU Costs for an Energy Efficient Cleanroom

    FFU Costs for an Energy Efficient Cleanroom

    A HEPA fan filter unit (FFU) is a crucial component of every cleanroom environment. Making the correct decision as to which type of FFU is the most appropriate for your application is not something to simply gloss over. There are two main categories of motorized fan filter units: permanent split capacitors (PSC) and electronically commutated motors (ECM). Both types of fan filter modules provide a perfunctory standard for any cleanroom, but differ by way of efficiency, durability and cost. PSC systems save you money upfront and are ideal for small, consistent projects. However, when considering longer endeavors, especially those with ever-changing circumstances, the ECM will pay for itself with energy savings. For instance, in California at an average of 14.47 cents per kilowatt hour, you would make the difference between the higher upfront costs of the ECM over the PSC bac

  4. How Fan Filter Units Fight COVID-19

    How Fan Filter Units Fight COVID-19

    In addition to face masks, properly maintained air filters remain crucial in confined indoor spaces to help mitigate the spread of COVID-19 (SARS-CoV-2 virus). Both HEPA filters and ULPA filters reduce the number of microscopic particles in the air, which can keep air safe to breathe in places it’s needed most like hospitals, isolation rooms and crowded indoor areas.

    COVID-19 virus spreads through the air on respiratory droplets created from talking, coughing, sneezing, and even breathing. When these activities occur in a populated space with stale air, the likelihood of transmission can significantly increase, as COVID-19 has been proven to remain viable for at least 3 hours lingering in the air or on surfaces up to four meters away from its last host.

    Masks and social distancing significantly re

  5. Did You Know? | Fan/Filter Units Do More Than Meet ISO Requirements—they also prevent infection

    Did You Know? | Fan/Filter Units Do More Than Meet ISO Requirements—they also prevent infection

    Most cleanroom professionals understand that Fan/Filter Units (FFUs) capture contaminants that degrade particle-sensitive samples. But they also remove bacteria, viruses and mold spores that contribute to a host of infections.

    With the threat of superbugs on the rise in medical facilities, sterilization has never been more crucial. Superbugs, or drug-resistant bacteria that cannot be killed by standard antibiotics, have the potential to cause infections that are increasingly difficult to cure. The number of deaths related to these bacteria is decreasing. But the bugs, and the danger, remain present.

    Until new cures are developed to battle bacteria, the solution to preventing the spread of germs is to update cleanliness procedures in hospitals, pharmaceutical manufacturing facilities and other places where drugs are regularly developed or used. Hand-washing can push back against the threat, but

  6. Charcoal Filters 101 for Critical Environments

    Charcoal Filters 101 for Critical Environments

    Activated charcoal is highly porous carbon used in air filters to capture solvent fumes and organic compounds by adsorption of molecules (van der Waals forces). Unlike particle filters, which rely on micro-pores to capture solid contaminants suspended in air, Terra’s coconut-shell based charcoal filters remove a wide range of chemical fumes and odors common to laboratories and manufacturing environments. To understand chemical vapor filtration, let’s first focus on what having a carbon-based filter means.

    Did you know...

    Traditional charcoal is a common commodity, found in everyday-homes (cooking barbecues, vacuum cleaners, etc.). But did you know your water filter may contain activated carbon? Drinking water is often filtered through activated charcoal to remove certain toxins, and improve the odor and taste.

    What does “activated” mean?
