I was prompted by this thread to check the Price of the WA8039 on Amazon where I had previously bought one before.
They had reduced the price on the 3 they had left in sock to $20 each. I bought 2 of them and got the free shipping.
So I now own a total of 4 of the above Filters.

In Frams defense the Filter Media is also 100% synthetic.

"Stop Replacing Your Air Filter!
FRAM engineering has developed a revolutionary air filter featuring 100% synthetic media which is designed to:

•Filter 99% of harmful particles
•Wash in minutes for like-new performance
FRAM Washable Premium Air Filter is designed to perform like new after every wash

•Construction that's built to last!
•High-density gasket for increased durability
•Heavy Gauge stainless steel screen
•Easy to wash!
Using a bucket and household dishsoap, this filter can be cleaned in 15 minutes with minimal down-time for drying."

Of course it does not say what size the 99% of the harmful particles are.
I have read claims it can be washed 10 time and now they say 20 times.
I am guessing that they will be able to be washed more than that.
