ABSTRACT:
The invention relates to a method of treating reticulated foam with a controlled migration treatment medium to produce an improved air filter. Reticulated foam is treated with a highly viscous oil that protects the foam from hydrolytic degradation and increases efficiency of the filter without causing unacceptable air restriction of the foam. An improved air filter made from treated and untreated layers of reticulated foam is also shown.
