Quick Answer
To build a simple air filtration system for decontamination, use a HEPA filter, a fan, and a plastic container to create a portable and effective air purification unit. This system can help remove airborne contaminants, including chemicals, dust, and other particles.
Selecting Materials
To build a simple air filtration system, you will need the following materials: a HEPA filter (at least 99.97% efficient for particles 0.3 microns in size), a fan (12-volt DC or a battery-powered option), a plastic container (at least 5 gallons in size), and a power source (batteries or a 12-volt DC adapter). The HEPA filter should be placed inside the plastic container, and the fan should be positioned to blow air through the filter.
Building the System
To assemble the system, place the HEPA filter inside the plastic container, and secure it with duct tape or other means of attachment. Connect the fan to the power source, and attach it to a vent or opening in the plastic container. This will allow the fan to blow air through the filter, purifying the air before it exits the container. The system can be powered by batteries or a 12-volt DC adapter, providing a portable and effective air purification unit.
Operating the System
To operate the system, simply plug in the power source or insert the batteries, and turn on the fan. This will create a flow of air through the HEPA filter, removing airborne contaminants and purifying the air. The system can be used in a variety of settings, including evacuation areas, chemical exposure sites, or other environments where airborne contaminants are present.
