You Can't See It, But Your Shower Water Is Working Against You
Every time you step into the shower, you're exposed to chlorine, chloramines, and potentially heavy metals. Chemicals are added to our 'town' water supplies to kill bacteria, but they are harsh enough to strip your skin's natural oils and damage your hair over time.
A shower filter is designed to remove or reduce these contaminants before they reach you. But how does it actually work?
What's Inside a Shower Filter?
At the heart of every effective shower filter is a filtration media. These materials physically or chemically capture unwanted substances as water passes through.
The Süla Premium Wellness Shower Filter uses a multi-stage filtration system designed specifically for our kind of water conditions. As water flows through the filter housing, it passes through layers that target:
- Chlorine and chloramines: the primary culprits behind dry, irritated skin and colour-faded hair
- Heavy metals: like lead and copper that can leach from older pipes and can be more concerntrated in rain and bore water.
- Sediment and particulates: that cloud your water
The Filtration Process, Step by Step
Here's a simplified look at what happens from the moment water enters your shower filter:
- Water enters the filter housing attached to your shower hose or arm
- It flows through the refill capsule which contains the active filtration media
- Contaminants are captured and either adsorbed onto activated carbon or neutralised by the filtration media
- Cleaner water exits through your shower head at normal pressure
The process happens in seconds, with no drop in water pressure. You won't notice any difference in flow, just in how your skin and hair feel after a few weeks.
Does It Work on Hot Water Too?
Yes, and this matters more than most people realise. Hot water causes chlorine to vaporise, which means you're not just washing in it, you're inhaling it. Our shower filter works across the full range of shower temperatures, so you're protected whether you prefer a cool rinse or a steaming hot soak.
How Long Does the Filter Last?
This depends on your water usage and local water quality. As a general guide, the filtration media inside your shower filter becomes saturated over time and needs to be refreshed. The good news? You don't need to replace the whole unit.
The Süla Refill Capsule lets you simply swap out the internal media and keep using the same filter housing, a more sustainable and cost-effective approach. Most households replace their refill capsule every 3–6 months depending on usage.
Not sure when it's time? Watch for these signs: your hair feels drier, your skin is more irritated after showers, or you notice a stronger chlorine smell. These are signals your capsule is ready for a refresh.
Is a Shower Filter Worth It?
If you're in New Zealand or Australia, the answer is almost certainly yes. Both countries treat 'town' water with chlorine as standard practice which is great for drinking water safety, but less ideal for daily skin and hair contact.
For anyone with sensitive skin, colour-treated hair, eczema, or simply a preference for a more natural shower experience, a shower filter is one of the most practical upgrades you can make to your bathroom routine.
