Product review (1 stars): than the old full one and now it sounds like it is sucking air
The new filter was slower, when we finally got it to work, than the old full one and now it sounds like it is sucking air.  It would not prime at all, we ended up putting water in it a little at a time out of the faucet and now it just trickles.  NOT happy, so we ordered another PUR filter.
