The dusted HEPA filter is a type of air filtration system that uses a high-efficiency particulate air (HEPA) filter to remove particles and contaminants from the air in a building. The dusted HEPA filter is designed to capture larger particles, such as dust, pollen, and dander, which can be difficult to remove with traditional HEPA filters. The dusted HEPA filter is typically installed in the ductwork of the building, which distributes the filtered air throughout the space. This type of filtration system is commonly used in commercial buildings, hospitals, and other large facilities where clean air is essential for health and safety.

The housing material of a ducted HEPA filter can vary depending on the specific manufacturer and model. However, most ducted HEPA filters are made from durable materials such as stainless steel or aluminum, which can withstand the pressure and temperature changes that occur in the ductwork. The housing may also be designed to prevent the growth of mold and bacteria, which can be a concern in humid environments. Additionally, some ducted HEPA filters may have a powder-coated finish for added protection against corrosion and rust.
In addition to the HEPA filter itself, there are several other accessories that may be used with a ducted HEPA filter system. These can include:
1. Air intake grille: This is a metal or plastic grille that covers the opening where air enters the ductwork. It helps to prevent debris and contaminants from entering the system.
2. Air discharge grille: This is a similar grille that covers the opening where filtered air exits the ductwork and enters the building.
3. Damper: A damper is a valve that regulates the flow of air through the ductwork. It can be used to control the amount of filtered air that is distributed throughout the building.
4. Motorized blower: Some ducted HEPA filter systems use a motorized blower to force air through the filter and distribute it throughout the building.
5. Humidistat: A humidistat is a device that measures the humidity level in the air and adjusts the operation of the HEPA filter system accordingly. This can help to prevent the growth of mold and bacteria in the filter.
6. Controller: A controller is an electronic device that monitors and controls the operation of the HEPA filter system. It can be used to set schedules for filter replacement, monitor filter performance, and alert maintenance personnel when filters need to be changed.
The air flow direction of a ducted HEPA filter is typically from the bottom up. This means that the air enters the ductwork at the bottom of the filter and is forced upwards through the HEPA filter media by a motorized blower or other air moving device. The filtered air then exits the top of the filter and is distributed throughout the building via the ductwork.
It's worth noting that some ducted HEPA filter systems may have a reversible design, which allows the air flow direction to be reversed if necessary. This can be useful in certain applications where it's important to ensure that all parts of the filter media are used evenly over time.
