Hi Eric,
Have you tried searching for it on Amazon?

Let me know.

Thanks,

I accidentally placed the old used filter back in the casing and the light turned green and stayed green for about three months…. What????

Oh noooo. You can’t run hot or even warm water through the filter, That will ruin the the filter. Only the cold tap water should be used. It says on the instructions to run the Cold water through a new filter for about 5 minutes to remove the initial residue that feels as you described. Then it is good to go. Never use the warm/hot water.

How is the water purified

When I first installed the PUR faucet attachment it worked great,the water was flowing fine and then over a two week period the flow turned into a trickle. I bought three replacement filters and just like the last one they all petered out after about two weeks. Also after installing a new filter the water coming out contained some kind of clear greasy substance. After running hot water through it for a couple of hours
it seemed to disperse.

1. Fitting the filter to the faucet. The filter came with an adapter (s?) that did not work with my faucet threads. At the time, I was using a Delta faucet. I contacted Delta and they sent an assortment of plastic adapters, one of which I used to fit the threads on the faucet at one end, and the threads on the filter at the other end.

2. A red light appears when it’s time to change the filter. Even after the change, the light continued to glow red. Deep inside the plastic housing, there is a T-shaped button. Sometimes, after removing the used filter, the button will remain depressed. Before inserting the new filter, make sure the button is popped out. If not, I use a pointed knife to press/pry the button until it pops out. Then the light will progress through the normal green-yellow-red cycle.

3. Because of the shiny slippery surface, it is difficult to fully tighten the housing cap, leaving a small gap between the housing and the cap. If there is a gap, high pressure inside the filter will cause a blowout and spray water afar. I used a thin coating of Vaseline to coat the ring gasket, allowing me to fully tighten the cap until there was no gap and no leak.
