Your Shower Filter Has a Best-Before Date... Sort Of
A shower filter isn't quite a set and forget solution. The filtration media inside your Süla Shower Filter does a lot of work. Capturing chlorine, chloramines, and heavy metals with every shower. Over time, that media becomes saturated and less effective. When that happens, you're essentially showering without filtration.
The good news: you don't need to replace the whole unit. The Süla Refill Capsule is designed to drop in and refresh your filter in minutes, restoring it to full performance.
How Long Does a Refill Capsule Last?
As a general guide, most households should replace their refill capsule every 3 to 6 months. Where you fall in that range depends on a few factors:
- How many people use the shower: a busy family bathroom will exhaust the media faster than a single-person household
- Your local water quality: areas with higher chlorine levels or harder water will deplete the capsule sooner
- How long your showers are: longer showers mean more water processed, and faster media saturation
As a practical rule: if your household has two or more regular users, plan to replace your capsule every 3 months. For solo users, every 4–6 months is typically sufficient.
Signs It's Time to Replace Your Capsule
Your body will often tell you before the calendar does. Watch for these signals:
- Your hair feels drier or more brittle after showers than it did when you first installed the filter
- Your skin feels more irritated or tight a sign chlorine is getting through again
- You can smell chlorine during or after your shower
- Colour-treated hair is fading faster than usual
- It's been more than 6 months since your last replacement
If you're experiencing any of the above, it's almost certainly time for a fresh capsule.
What Happens If You Don't Replace It?
An exhausted refill capsule doesn't just stop filtering in some cases it can actually release previously captured contaminants back into your water. This is called back-flushing, and it means an overdue capsule could be doing more harm than good.
Staying on a regular replacement schedule keeps your filtration effective and your shower water consistently clean.
How to Replace Your Süla Refill Capsule
Replacing your capsule is a quick, tool-free process:
- Unscrew the filter housing from your shower hose or head
- Remove the spent refill capsule
- Insert your new Süla Refill Capsule
- Reattach the housing and run water for 30 seconds to activate
That's it. The whole process takes under two minutes.
Make It Easy: Set a Reminder
The simplest way to stay on top of refill timing is to set a recurring reminder on your phone the day you install a new capsule. Pick 90 days for busy households, or 150 days if you're a solo user. You'll never need to guess.
