The last few times I have ordered this filter I have bought the 2-pack because it was cheaper - HOWEVER the last 2-pack came shipped only in bubble wrap and the tip on the 2nd unit had snapped off rendering it unusable - AND since it had been 6 months I couldn't return it. Word to the wise - - either inspect carefully upon arrival or only order single units.
