PRLA Restaurant & Lodging Matters Fall 2020

10 •  PENNSYLVANIA RESTAURANT & LODGING matters  •  Fall 2020 AIR FILTRATION KEY COMPONENTS AND SCIENCE The recommendation from the EPA, CDC, and other agencies is to get a HEPA 13 or better air purifier capable of circulating a large amount of air. This type of filter is referred to as “Deep HEPA.” Deep HEPA can capture particulate matter as small as 0.3um (0.3 micrometers). The truth be told, a single COVID-19 virus molecule is approximately 0.125 μm. However, up to 90% of the virus is agglomerated to small water droplets, increasing the overall size of the particulate matter, making deep HEPA a scientifically proven method to capture airborne COVID-19. In addition to HEPA, a new technology called Needlepoint Bi-Polar Ionization (NBPI) is being incorporated into portable purifiers by a limited number of manufacturers. NBPI is proven to neutralize virus molecules by damaging its RNA structure. NBPI also increases particle clustering so that the HEPA filter will capture the particulates once the air carries it to the filter. COMMERCIAL UNITS BUILT FOR COMMERCIAL USE There are several key features to consider when looking for a Satellite HEPA unit. It must be: • Durable It needs to withstand collisions with people and equipment with little chance of damage. • Portable It must be portable enough (e.g., having strong, lockable caster wheels) to be moved around the space as needed, but it should also allow you to lock the wheels to keep the unit in place. • Easy to Install and Operate The installation and operation of the unit must be as easy as operating a refrigerator. No maintenance or service personnel required. It should be a “set it and forget it” design. • Little and Easy Maintenance HEPA filters should last a minimum of one year, and it should be easy for staff to change filters. • Low Operating Costs The yearly cost of consumables (e.g., filters and lights) must be as low as possible. • Built-to-Last and Easily Repaired It must be built-to-last, and if it ever does need to be repaired, it should be easily repairable to protect your investment. • What Type of Air Purifier Should I Buy for My Restaurant?
