Duct cleaning has not been
shown to prevent health
problems, nor is scientific
evidence currently available
to conclusively demonstrate
that particle (e.g., dust)
levels in homes increase
because of dirty air ducts.
The U.S. Environmental
Protection Agency does not
recommend that air ducts be
cleaned routinely, but only
as needed. When health
problems are believed to be
the result of biological
contaminants or dust in
indoor air, it is important
to first determine that
contaminated ducts are the
cause of the health problems
and verify that the ducts
are, in fact, contaminated.
The source of the problem
may lie elsewhere, so
cleaning ducts may not
permanently solve the
problem. |
