Filtration At Its Finest

Why fluoride-free water?

From skeletal fluorosis, a condition that weakens bones, to potential impacts on the thyroid and nervous system, the risks associated with fluoride ingestion are growing. Children are particularly vulnerable to fluoride's effects, with studies linking it to lower IQ and impaired cognitive development.
It's crucial to be informed about the fluoride levels in your water supply. Phoenix Gravity POSTreat fluoride removal cartridges are designed to remove up to 95% of the fluoride in your water. Because we care about your health and the well-being of your family.

FAQs

Is the POSTtreat compatible with all gravity filters or just the Phoenix Gravity Filter?

The POSTreat is compatible with all gravity filtration systems. Remember, it can’t be used alone - so you must have a gravity filtration system and existing Carbon Cartridge to use it.

Can I set it up myself?

Absolutely. The POSTtreat is designed for easy DIY set-up with your Phoenix Gravity System. 
You simply attach your POSTtreat cartridges to the exposed thread of the Carbon Cartridges. We’ll send detailed assembly instructions with your POSTreat filter.

Can I clean my POSTtreat Fluoride Filter?

Yes, it’s simple! You can clean the stainless steel casing of the POSTreat filter - without the FluoRid media inside - in your home using tap water and a soft brush or mild abrasive. The FluoRid media itself will need to be replaced every 4 months. We’ll include detailed instructions when we send it to you.
