Two-stage filtration at its finest

Stage one: Tortuous Path
Activated carbon creatives a tortuous path that contaminants like microplastics, cysts and bacteria cannot pass through
Chemicals like chlorine, lead, pesticides and more are absorbed by activated surface 
Stage Two: Sterilising 
Impregnated silver sterilises water and prevents growth of bacteria or mould

Better quality you can taste, on tap.

FAQs

Are the activated carbon cartridges compatible with all gravity filters or just the Phoenix Gravity Filter?

Yes! Our advanced Carbon Cartridges are compatible with all gravity filters including Berkey and Doulton. If you’re not sure about your filter, just drop us a line and we’ll be happy to assist you contact here.

Can I set it up myself?

Absolutely. The carbon cartridges are easy to replace on your own - without tools or a professional - and installed in your Phoenix Gravity System within minutes. 

You simply remove the old cartridges from the upper chamber of your filter and replace them with the new. We’ll send detailed assembly instructions with your new delivery - and our team is always available via chat, email and phone to provide help and support. Contact here

Can I clean my carbon cartridges?

Generally, you won’t need to clean your cartridges - but they should be replaced within 18 months. If you notice the flow slows down, it may mean the cartridge is blocked. In this case, you can easily clean your filter in your home using tap water and a soft brush or mild abrasive. We’ll include detailed instructions when we send it to you.

How does the Phoenix Gravity Filter compare to plastic jugs or other filters?

The Phoenix Gravity is one of the most advanced filtration systems on the market. With a Phoenix Gravity System, your water is purified through three-stages of activated carbon filtration to remove 99.9% of contaminants including bacteria, parasites, cysts, pesticides, heavy metals and more.  This means we can trap physical contaminants that are more than 20 times smaller than jug filters. Combined with our higher filtration contact time we are 20 times more powerful than typical jug filters and those using granular carbon.

Our stainless steel chambers not only prevent microplastics and other harmful chemicals from leaching into your water, but also hold significantly more purified water than the average jug. This makes it even easier for you to enjoy fresh, nutrient-rich hydration - whenever you need it most. Unlike Reverse Osmosis (RO) filters, the gravity system does not require electricity to run or a plumber to install - and it won’t strip your water of the healthy nutrients your body benefits from.

Since purchasing my Phoenix Gravity and filters my tap water has no chemical tastes. It’s comforting to know I’m drinking safe refreshing water with no after taste.

I had to switch from a spring-fed supply to mains, so I bought the Phoenix Gravity Water Filter with the Fluoride remover, and it's brilliant. The water is delicious —my daughter agrees!

Great addition

When i first started with Phoenix, I brought the Carbon filter as was desperate to have filtered water. Now Finally i got the Postreat Fluoride removal filter and it’s made the water taste even better and so much fresher. I feel confident knowing i am removing 95% of Fluoride especially having two young children. Also appreciate the thought from the design team who made the unit from stainless steel. Meaning no leeching plastic.

I now have great tasting water and properly safe drinking water.
