What You'll Need

The fan/filter is a DIY and low cost strategy to remove particles in the air. Our team recommends the use of a MERV 13 20x20 4" filter for desired filtration and longevity. Through our selected Low-Cost Monitoring Project participants,we have seen promising results in reduction of indoor particles (0.5+ microns) in ranges that we are measuring.

The fan/filter can be placed in a window to filter outdoor air as it comes into your home or used within a space. Fan/filters are particularly useful if homes rely on open windows during the summer months for comfort.

 

Materials

• MERV 13 20x20 4” Furnace Filter
• 20x20 Box Fan
• Foil-faced. Duct. or Cellophane Tape
• Pair of scissors/utility knife

 

Steps

1. Find the arrow indicating air flow on the filter; make sure this matches the direction of the fan’s air flow
2. Place the filter on the box fan.  We recommend placing the filter on the front of the box fan if placed in a window.  The filter can be placed on the back of the box fan if used to recirculate the air within a room.  
3. Secure the filter to the fan by using tape; completely seal the filter to the fan with tape.
4. Plug in the fan/filter and run on low.  Your DIY fan/filter is complete!
5. Change the filters as needed. Filters typically last for 3-6 months, longer if used within a room, rather than to filter air coming in a window.
