The PAIR Program is now CLOSED. For more information about any upcoming programs please email airinfo@sdapcd.org.
The PAIR Program provides new portable air purifiers and indoor air
  monitoring systems to selected residences in the Portside area, at no
  cost to participants. Eligible households will also receive three
  extra filters for the air purifier, and a small one-time monetary
  stipend to partially reimburse participants for antipated electrical
  costs to run the new devices. The Portside area encompasses parts of
  Barrio Logan, Logan Heights, Sherman Heights, and National City
  neighborhoods, and is ranked within the top 15% of most polluted
  neighborhoods in California. The low-income area is particularly
  impacted by poor air quality being adjacent to and downwind of the
  industrialized waterfront, Port areas, and local freeways along San
  Diego Bay.
