Airborne Disease Filter

  

Keep your family safe from airborne biological threats

Infected people can broadcast viruses and bacteria in droplets and aerosols. These are both fluids that can infect other people. Droplets will land on a surface up to a couple of yards from the source and aerosols will go much farther. They can even be drawn into heating, air conditioning, and ventilation systems and be spread throughout a home.

 

There are two ways to deploy this air filtration system:

   

Safe Cell NBC air filtration system

Positive Pressure Safe Room

The filter is inside the safe room.

Outside air is drawn through the intake hose into the bottom end bell and up through the two pre-filters and the nuclear grade HEPA filter. It’s then blown out of the top exhaust port of the filter with enough pressure to ensure that if there are any leaks in the safe room, the air flows outward through them.

You must take measures to seal up the safe room, but this pressure differential will not allow any unfiltered air to enter  through small leaks.

Negative Pressure Protected Space

The filter is in a room adjacent to the protected space; separated by an interior wall.

Air from the protected space is drawn through the intake hose into the bottom end bell and up through the two pre-filters and the nuclear grade HEPA filter. The filtered air is then exhausted to the outside through the discharge hose.

You must take measures to seal up the protected space, but this pressure differential will not allow any unfiltered air to escape through small leaks. 
  

No matter which mode you are in, these five rules apply:

  1. The safe zone is ALWAYS the room with the non-infected people.
  2. The filtration system ALWAYS goes in the safe zone. This allows the non-infected people to ensure it’s continued operation.
  3. There is ALWAYS a pressure differential between the safe room/protected space and the rest of the home and the outside. Compared to the normal air pressure in your home, safe rooms have more pressure and protected spaces have less pressure. This keeps bio-aerosols OUT of the safe room or INSIDE of the protected space.
  4. The dirty air is ALWAYS drawn in through the bottom hose of the filter.
  5. The clean air is ALWAYS blown out of the top of the filter.

Easy installation

The Airborne Disease Filter comes fully assembled. It sits on the floor and plugs into a normal wall outlet with the included 120 volt AC to 12 volt DC power supply.

The marine grade blower runs on 12 volt DC and uses only 52 watts of power. If the grid goes down, you can use the included battery clips to run it off a deep cycle battery. Just unplug the power supply from the power port on the filter and plug in the battery clips.

The hoses slip right onto the intake and exhaust ports of the filter and the wall mount flanges without tools. The bolts between the top and bottom end bells are hand tightened to slightly compress the gaskets on the HEPA filter.

SAFE ROOM MODE – you will need a four inch diameter port through an exterior wall. The easiest way to do this is install a dryer vent kit like this one, with the flapper valve removed. Trim the penetration pipe that comes through the wall so that it is flush with the inside wall.

Once you have your dryer vent kit installed:

  1. Mount one of the included wall mount flanges with its gasket right over this port on the inside of the wall.
  2. Slip one end of the intake hose onto the wall mount flange and slip the other end onto the bottom intake port on the filter.
  3. Plug in the filter and turn it on.

PROTECTED SPACE MODE – you will you will need a four inch diameter port through an exterior wall and a four inch diameter port from the isolation room to an adjacent room. A corner between an exterior wall and an interior wall works best. The bottom end bell can be rotated so the intake port points in either direction.

  1. Mount the included wall mount flanges with their gaskets right over these two ports.
  2. Slip one end of the intake hose onto the wall mount flange on the interior wall and the other end onto the bottom intake port on the filter.
  3. Slip one end of the discharge hose onto the wall mount flange on the exterior wall and the other end onto the top exhaust port on the filter.
  4. Plug in the filter and turn it on.
     

  

Air Filtration

Most so called “HEPA filters” are imported from China and are batch tested. A sample of filters from each batch is pulled from the line and inspected.

The Airborne Disease Filter comes with an American made high efficiency particulate air filter that has been individually serial numbered and tested by the manufacturer. This test is performed by placing it in a test chamber that blows air through it at a known pressure and airflow. An inert test particle is introduced into this airflow upstream of the filter and the concentration is measured downstream. Every single HEPA filter we supply is tested this way and the specific performance data is on a placard on the side of the filter.

These true HEPA filters have a minimum 99.97% filter efficiency that meets NIOSH P100-series respirator test criteria and feature a gasket on both sides. These gaskets mate with shoulders molded into the top and bottom end bells. They are evenly compressed by the eight bolts that run between the top and bottom end bells to provide a secure seal.

This is the same nuclear grade HEPA filter we use in the Safe Cell Nuclear, Biological, and Chemical air filtration systems. We’ve been in continuous production of the Safe Cell for 18 years.

There are many optional accessories available – four are shown below. The rest can be seen here. All of our accessories will work with any of our filtration systems.
