Set of two ozone plates for FM1, FM2, Pro 4 & Pro 8. Plates need to
be cleaned every 2-3 months. These plates are replacements that should
be replaced every 1-2 years.
Keeping an extra set of plates on
hand simplifies this process so you never have any down time. (Note: The
Pro 8 needs 4 pairs all others above need only 1 pair)
