GSS Imperial British Berkefeld gravity filter for chemical and microbiological filtration

I am writing to ask for a quote to purchase the GSS Imperial British Berkefeld gravity filter for chemical and microbiological filtration .I am still in the process of doing my research on other similar products.
This may sound odd, but could you recommend any of your competitor’s products that may be close to yours?
Your company’s products we’re the first and so far only one that I am considering, but it never hurts to have the knowledge.

You may be able to find Katadyn gravity filter with ceramic only called Ceradyn or combination ceramic with carbon called Gravidyn but their candles are same as our standard 2" as opposed with our Imperial Supersterasyl 2.75" in diameter for higher water production.
Doulton ceramics are the only one in the world to pass NSF Int'l arsenic and cadmium extraction test. This does not imply that Katadyn ceramics leach out these commonly found contaminants in ceramics.

When will "Model GCC Classic Gravity Filter" be in stock?

Model GCC has been discontinued however the 10" Supersterasyl filter replacement elements for this model will be available indefinitely.

My next choice, after the GCC, is the GSS2 w/ fluoride elements.

How would the GSS2 (with fluoride elements) compare, in purification ability, to the CP200UC+ (with fluoride elements)?

Same, both will take out fluoride/heavy metals to none detectable level.
