Fluoride Removal:

A Pair of POSTreat Fluoride Removal cartridge is designed to remove >95% of fluoride from your water. Continued ingestion of artificially added fluoride can lead to long-term health issues e.g. osteoporosis. Made from 304 Stainless Steel and containing our own proprietary media, our unique refillable cartridge is designed to be used in conjunction with the Phoenix Gravity Water Filter Cartridges. Vital naturally occurring minerals are retained. The POSTreat DOES NOT affect TDS.

Durable, Sustainable, Reusable, Safe:

Made from the highest grade 304 stainless steel (like our Phoenix Gravity Water filter)- the most chemically neutral and safest material in domestic water filtration. Naturally BPA free and non-leaching, it will not corrode or re-contaminate your water like many alternatives.The filter casing has been formulated to be a non-disposable option- simply refill with sachets of new media every 4-6 months (optimum performance).

Highly Compatible:

Our Phoenix Gravity POSTreat Fluoride Reduction Filter is compatible with any gravity water filter with a thread size of ¼ inch (and its cartridges). So you can benefit from our sustainable reusable, refillable cartridges no matter your current Gravity System (including Berkey, Doulton and more). Please note, as with most fluoride reduction filters, the POSTreat must be used in conjunction with a primary Gravity Water Filtration cartridge, it’s not a stand-alone.

Convenient and Simple to Use:

Like our Gravity Water Filters, the POSTreat requires no specialist knowledge nor technical expertise to use. They are easily assembled (non-plumbed) using our simple step-by-step guide, avoiding expensive and inconvenient plumbing. Gravity Filters produce higher volumes of water than jug filters and can provide better filtration. By having filtered water on tap, you can dispense with the need for bottled water- fill up your bottle straight from the Phoenix Filter.

Greater than 95% Fluoride reduction with the two POSTreat Steel cartridges.


Our POSTreat can be used in gravity water filters to remove fluoride ions from drinking water. Gravity water filters use a combination of carbon filters, along with the POSTReat Fluoride reduction filter, to remove impurities and fluoride from water while passing through a bed of activated alumina, which adsorbs fluoride ions. This process can remove up to 95-98% of fluoride ions from water.

The POSTreat filters reduce >95% of fluoride from your water. Because of the slow and steady water flow inside the filters. Under normal conditions it is recommended that each set of Phoenix Gravity POSTreat filters are to be replaced every 6 - 8 months for a family of four.


Easy Installation no tools required. Phoenix Gravity POSTreat Steel fluoride reduction filter will fit into any gravity water filter cartridge which has a thread size of ¼ inch.

Enjoy fresh and healthy water with eco friendly phoenix gravity POSTreat fluoride reduction element.
