Replacing your shower filter can surprisingly brighten your day: water flows again with good pressure and feels cleaner. However, once a new filter is installed, many wonder what to do with the old one.
Does it belong in plastic recycling, electronic waste, or mixed waste? The answer is clear once you understand what's inside the filter casing.
Why can't a shower filter be put in plastic recycling?
This is the most common question we receive. Since the filter casing is plastic, plastic recycling seems like the obvious place. However, the truth is different.
A shower filter is a composite product, meaning it consists of several firmly combined materials. Inside the plastic casing is an effective sediment filter.
In use, the filter collects solid particles from the water. Our efficient sediment filter captures all particles larger than 5 microns, such as:
-
Rust from old pipes
-
Sand and sediment
-
Metal particles
-
Also limescale
Therefore, a used filter is full of impurities. Recycling plants do not have the technology to separate the plastic casing, filter material, and the metals and sediment bound to it. That's why the filter cannot be sorted as plastic waste.
The right place for an old filter is mixed waste
So, an old shower filter belongs in mixed waste, which in many municipalities is called combustible waste.
When sorted correctly, the filter does not end up in a landfill but is utilized in energy production. Your old filter is thus converted into district heating or electricity.
Here's how to dispose of the filter neatly:
-
Drain the water: Let the filter dry for a moment so that excess water drains out.
-
In a bag (optional): You can put the filter in a small bag to prevent any rust particles from dirtying the trash can.
-
To mixed waste: Place the filter in your household mixed waste bin.
Easy and quick.
What about empty aroma gel cartridges?
Many of our showerheads also use aroma gel cartridges that condition the skin. Unlike the filter, an empty cartridge can be recycled.
The cartridge casing is pure plastic. Once it's empty, rinse it lightly, let it dry, and place it in plastic recycling. This isn't just about scents; it's about genuine Korean cosmetics. The cartridges contain four skin-moisturizing natural ingredients: aloe vera, snail serum, milk protein, and vegetable glycerin.
When is the right time to replace the shower filter?
Regular shower filter replacement ensures that your shower works flawlessly. But how do you know when it's the right time?
The surest sign is weakened water pressure. As the filter fills with impurities, water flows through it less effectively. If your shower feels sluggish, a clogged filter is almost always the culprit.
Your eyes also tell a lot. Thanks to the transparent casing, you can directly see when the originally white filter turns brown. This is a clear sign that the filter is working and it's soon time to replace it with a new one.
As a rule of thumb, the replacement interval is 3–6 months. However, the actual need depends entirely on the quality of the local water and consumption. In areas with old piping or a lot of sediment and limescale in the water, a shower filter replacement may become necessary every 2–3 months.
Summary
With a little effort, you'll get a better shower and handle recycling honorably. Just remember this clear instruction: a used filter goes into mixed waste, an empty aroma cartridge into plastic recycling.
If you haven't bought a new filter yet, you'll find efficient sediment filters in our online store that effectively remove rust, metals, and other impurities from the water. They are perfectly suited for the popular Aroma Sense and Aromica showerheads and guarantee a clean shower experience month after month.
Frequently Asked Questions
Can I clean and reuse an old shower filter?
We do not recommend this. The small particles collected by the filter are deep within the material and cannot be rinsed out. Attempting to clean it would likely damage the filter structure and reduce its effectiveness. Only a new filter guarantees clean and safe shower water.
What happens if I don't replace my shower filter regularly?
If the filter is not replaced, it will eventually become completely clogged, causing water pressure to plummet and filtration capacity to be lost. In the worst case, a clogged, damp filter can become a breeding ground for bacteria. Regular replacement is therefore important for both comfort and hygiene.
How do aroma gel cartridges condition the skin?
Our cartridges contain Korean cosmetics, not just fragrances. They feature four natural, skin-conditioning ingredients: aloe vera, snail serum, milk protein, and vegetable glycerin. These substances dissolve in the shower water and help counteract the drying effects of water.
How do I know which filter is suitable for my shower?
The easiest way is to check the brand and model of your current showerhead. Our filters are specifically designed for Aroma Sense and Aromica showerheads and fit them perfectly. If you are unsure, you can always contact our customer service – we'll be happy to help you choose the right product.
Why does the filter go into mixed waste and not plastic recycling?
The filter is a composite product consisting of a plastic casing, filter material, and impurities collected during use, such as rust and metals. Since recycling plants cannot separate these components, the product is not suitable for plastic recycling. Instead, it is utilized for energy along with mixed waste.
