me in his real estate column in Sunday’s New Mexican and his writing gave me
more credit than intended. I suggested the topic to him and supplied some
references. Richard Corsi came up with the idea of using MERV 13 filters (5 of
them to form a box for air being drawn into the fan) with a box fan as an
alternative to expensive air purifiers. Another friend thought it was my idea,
too, so I submitted a letter to the paper to clarify and add a couple qualifiers.
