If you’ve made the switch to a tap-mounted water filter, you’ve already taken a big step toward reducing plastic waste and improving your drinking water quality. But like any product that works hard behind the scenes, your filter needs a little care to keep performing at its best.
Here are 6 easy tips to help you get the most out of your Tappwater filter — safely, efficiently, and for the long run.
1. Use Cold Water Only
Your filter is designed for cold or cool water use only (below 40°C).
Using hot water can:
- Warp or damage the plastic housing
- Compromise the activated carbon inside the refill
- Increase the risk of bacterial growth
Quick tip: If you’re switching to hot water at the tap, make sure to move the lever to the “unfiltered” setting first.
2. Flush the Filter After Inactivity
If your filter hasn’t been used for a couple of days (e.g., after a weekend away), it’s a good idea to flush it with cold water for 30 seconds before drinking.
Why? Because water that sits inside the filter can:
- Taste stale
- Carry a mild odour
- Lose freshness and clarity
A quick flush brings your filter back to peak performance.
3. Flush New Refills Thoroughly
When installing a new refill cartridge, you might notice black or grey water at first. Don’t worry — that’s just harmless carbon dust from manufacturing.
Run water through the filter for at least 30 seconds, or until it runs clear.
Once flushed, the filter is ready to go.
4. Keep the Filter Away from Heat
Heat is the enemy of long-lasting filtration.
Avoid placing your filter:
- Near hot appliances (e.g., stovetops, kettles)
- In direct sunlight
- Under warm or hot running water
Heat can cause plastic parts to warp and reduce the effectiveness of the filter cartridge inside.
5. Don’t Clean the Housing with Soap
It’s tempting to wash everything with soap — but not your filter housing or valve.
Soaps and detergents:
- Leave residue that can affect valve function
- May damage rubber seals and plastic threads
- Can leach into your drinking water if not rinsed thoroughly
Instead, wipe the housing with a soft cloth and cold water, or use diluted vinegar for light cleaning.
6. Never Wash or Reuse the Filter Cartridge
Your refill is not meant to be cleaned or reused.
The activated carbon inside has a limited lifespan — once it’s saturated with contaminants, washing won’t restore it. In fact, adding soap or hot water can make things worse.
Replace your refill every 2 months for clean, safe, great-tasting water.
Final Thoughts
These care tips are simple, but they go a long way toward keeping your filter working exactly as it should. Whether you're filtering tap water for drinking, cooking, or filling your reusable bottles, proper maintenance means better performance — and a longer life for your filter.
