List of features

To understand why this filter suits so many people, you need to look at its technical specifications and design.

High-performance Smart Carbon CTC-60 technology

The compact activated carbon block forms the heart of the system. Its tiny pores mechanically trap chemical pollutants present in the water. It acts as a highly effective physical and chemical barrier.

This device removes heavy metals such as lead and mercury. It also acts on drug residues and pesticides. Tests confirm a drastic reduction in harmful contaminants.

We should point out, however, that essential minerals remain present. Magnesium and calcium pass through the system, confirming its status as a benchmark among the best gravity filter models on the market. The water retains its natural taste and benefits.

Durable 304 stainless steel construction

304 stainless steel is a top-quality food-grade material. It never rusts and does not impart any metallic taste to your drink. It is the standard in the medical and culinary industries.

This product stands out for its exceptional robustness. Unlike plastic, it is completely resistant to everyday knocks and bumps. Its chrome finish fits seamlessly into any modern kitchen.

It is worth noting that this product is completely free from Bisphenol A. Water is stored in a safe and neutral environment. This provides peace of mind for the long-term storage of your supply.

Tool-free installation and maintenance

Priming is the most technical step in the process. You need to soak the cartridges under the tap for a few minutes. This expels the air to ensure optimal filtration flow.

Assembly is a breeze. The two tanks simply slot together. The tap is screwed on by hand with its seals. No tools are required.

Cleaning is done simply with a soft sponge. Just rinse the tanks once a month. This prevents any limescale or dust build-up.

Users often note the change in taste. The water becomes neutral and very pleasant on the palate. This is the first positive point mentioned everywhere.

FAQ

How effective is the Phoenix Gravity at filtering water?+

The Phoenix Gravity is a real barrier against pollutants! Thanks to its Smart Carbon CTC-60 cartridges made from coconut shell activated carbon, it removes up to 99.9% of the most concerning contaminants. This includes heavy metals (lead, mercury), pharmaceutical residues, pesticides, PFAS and even microplastics. 🦠

What’s brilliant is that it doesn’t filter indiscriminately: whilst it stops bacteria and viruses, it lets essential minerals like calcium and magnesium through. This gives you purified, healthy water that retains all its nutritional properties and has a perfectly neutral taste.

How much do replacement cartridges for this system cost?+

This is where the Phoenix Gravity really stands out from the competition! A pair of main filter cartridges costs around €80 (or around $120 depending on stock). When you consider that a pair can filter up to 20,000 litres, the maths is simple: the cost works out at less than 2 cents per litre. 💸

If you choose to add the POSTreat filters for fluoride and arsenic, expect to pay around €77 for the pair. These need replacing roughly every 4 to 6 months, whilst the activated carbon cartridges can last up to a year depending on your usage. It’s a highly cost-effective investment compared to plastic bottles!

How do I choose the right filter size for my household?+

It all depends on your household size and daily consumption! We recommend taking a look at these three standard sizes: the 6-litre model is perfect for singles or couples (1–2 people), the 8-litre is a favourite with families (2–4 people), and the 12-litre is designed for large gatherings of more than 5 people. 👨‍👩‍👧‍👦

Bear in mind that the 8L model is the most versatile. It offers an excellent balance between workspace footprint and capacity. If you cook a lot with filtered water, don’t hesitate to go for the next size up so you never run dry!

Is installation and maintenance complicated?+

Not at all, it’s a piece of cake! The whole assembly takes less than 5 minutes and, best of all, you don’t need any tools. Simply screw the tap on by hand and slot in the 304 stainless steel tanks. The most important step is priming the filters under water to flush out the air, and hey presto, it’s ready! 🛠️

As for maintenance, a quick monthly clean of the tanks with a soft sponge is more than enough. If you notice the flow rate slowing down, simply brushing the cartridges with clean water (no soap!) will give them a new lease of life. It’s simple, robust and designed to last for decades.

Is the Phoenix Gravity really cheaper than a Berkey?+

Absolutely! The Phoenix Gravity is the ultimate budget-friendly alternative. Offering the same quality of steel and certified filtration performance (NSF 42 and 372), it is generally priced 30% to 50% lower than market leaders such as Berkey. 📉

It’s the smart choice for those who want complete self-sufficiency without paying the ‘brand premium’. What’s more, Phoenix cartridges are compatible with most other gravity-fed systems. So you benefit from cutting-edge technology with a 10-year warranty on the tanks, all at an unbeatable price.
