yes I have one the question is/was: Will it filter out hormons as in estrogen
There are lots of different types of filters how do I choose one?
Most filters use carbon to remove hormones, pesticides and solvents.
The jug-type filters are made from granular activated carbon. This is a bit like putting carbon granules in a tea bag and letting the water flow through. It will do something but it’s not the most efficient. It contains a resin which is good at removing calcium carbonate – this is found in hard water areas and gives the ‘scum’ on top of your cup of tea.
Filters with a carbon block are better. The carbon is powdered and then reconstructed into a solid block. This is more efficient than the granulated filter because the particles are very small so there is more surface area for the water to come into contact with. You can use this system to filter all the water in your house, not just the drinking water. They will remove hormones, pesticides, organic solvents and nitrates. Some are impregnated with other materials and so will also remove heavy metals.
Some sophisticated filters have ceramics, carbon block and resins. The carbon block does 99.9% of what you want apart from scale removal in very hard water, so you might want to add a descaler for your tap water.
Some carbons have silver added to them to prevent the growth of bacteria and algae. This is good when the filter is only going to be used intermittently with many days or weeks in between uses.
