Price Pfister Pfilter Pfaucet Replacement Filter by Teledyne Water Pik Model 734-2RF.
Where can I purchase it (in St. Louis?) or internet?

I contacted Teledyne Waterpik to see if they still had these filters and they have discontinued them. Unfortunately, they do not have any stock left in this filter.

We have many filtration options available on our website. We have faucet filters that connect directly to the faucet available here:

The best technology is the Reverse Osmosis Systems. These are installed under your kitchen sink with a dedicated drinking water faucet. They are located here:

Under sink systems are also very popular. They have much better filtration than faucet filters but they are not quite as good as the Reverse Osmosis Systems. One of the best under sink systems we have is the Culligan US-EZ-4 system:
