With most people looking for better ways to protect themselves against potential airborne transmission of COVID-19, many products on the market are being promoted as effective devices to implement in their residences and businesses. One major step towards reducing the risk of COVID-19 noted by many health safety organizations would be the upgrade of the building’s air filter to one that is rated at a MERV 13 level or higher.
It’s a strangely surprising task, changing your home air filters. There’s an arrow on the box, and it says to point in the direction of “Air Flow”, but what does that mean? It means the arrow faces the unit, or in other words, facing inside the space you’re putting it into. Assuming your unit is outside or in your attic, you want the arrow to face the unit.
Air handling unit (AHU) filters are used in an HVAC system to prevent dust and other contaminants from circulating in a building. They help improve indoor air quality, which has become an increasingly important concern for all facilities since poor air quality negatively impacts people’s health and productivity.
Recommendations for the Cleaning and Remediation of Flood-Contaminated HVAC Systems: A Guide for Building Owners and Managers
During flooding, systems for heating, ventilating, and air conditioning (HVAC) can become submerged in floodwaters. As a result, these systems may contain substantial amounts of dirt and debris and may also become contaminated with various types of microorganisms such as bacteria and fungi. The following recommendations will help ensure that HVAC systems contaminated with flood water are properly cleaned and remediated to provide healthy indoor environments.
The initial resistance of the HEPA filter refers to the air circulation resistance of the newly-made filter under the rated air volume state.
The resistance characteristic of the HEPA filter is one of the important characteristics of the high-efficiency filter. Under the premise of meeting the efficiency of people's needs, the resistance characteristic is related to the cost of use.
High-efficiency filters must be tested one by one before they leave the factory due to strict requirements on the place of use. They can be put into use only after being qualified. The filter test includes factory inspection and on-site inspection. During these two tests, the reasons for the unqualified filter may be as follows.
Features of ultra-high efficiency filter: Ultra-high efficiency filter provides a variety of configurations suitable for strict cleaning requirements such as clean rooms, dust-free workstations, clean workbenches, and FFU windmill filter sets.
