Mat,

For that money you buy the best filtration system on the market... the NS
Research 3 stage filter. Ever read the specs on these..?
http://www.gasblending.com/filters.htm , check it out.
I have been using these for years, never any problems. Far longer use out of
these elements, better quality air and same price.

Rgrds,

THOMAS
