Example 1: The refillable SETRENLO® InLine toilet vent
The activated carbon in all toilet vents ensures that unpleasant odors are absorbed. This should be changed once a year. However, changing it yourself is not possible with most commercially available products.
With SETRENLO® toilet vents, this is certainly possible. This saves you a lot of money and helps reduce plastic waste.
The SETRENLO® InLine toilet vent is suitable for all composting toilets. Activated carbon is included for the first three years. With comparable products, the entire container must be replaced annually. Activated carbon is only included for the first year.
Produkt | Anschaffungskosten (einmalig) | Verbrauchskosten (jährlich) |
|---|---|---|
SETRENLO® InLine-Klo-Entlüftung - nachfüllbar, nachhaltig | 239 € | 13€ |
Klo-Entlüftung mit Wegwerfbehältern aus Plastik | 205 € | 39€ |
Differenz | -34 € | +26 € |
When calculating the savings potential, we proceed as follows: We look at the acquisition costs and the annual consumption costs.
In this example, the purchase price of a standard toilet vent with a disposable plastic container is at least €34 cheaper than the SETRENLO® solution. However, the operating costs are somewhat different.
Save up to 312€ on consumables
For standard toilet vents, a refill cartridge costs approximately €39. Manufacturers recommend changing these cartridges once a year.
With the SETRENLO® InLine Toilet Ventilation System for all composting toilets, activated carbon is included for the first three years. This means you don't have to worry about it again until the fourth year. One liter of SETRENLO® Vegan Activated Carbon, for refilling, costs €39 and is sufficient for another three years. This means you'll save €13 per year, saving €26 per year.
For the long-term analysis of cost savings, we consider a period of 12 years. With the SETRENLO® InLine toilet vent, you can save a total of €312 in operating costs. The total cost, including the one-time purchase, still amounts to €289.


Example 2: The refillable SETRENLO® exhaust air filter
The activated carbon also ensures that unpleasant odors are absorbed in all exhaust air filters for urine, sewage, and wastewater tanks. This should be changed once a year. For exhaust air filters, this usually means replacing the entire product once a year.
The SETRENLO® exhaust air filter is suitable for all urine, holding, and wastewater tanks. Activated carbon is included for the first three years.
Produkt | Anschaffungskosten (einmalig) | Verbrauchskosten (jährlich) |
|---|---|---|
SETRENLO® Abluftfilter - nachfüllbar, nachhaltig | 139 € | 13 € |
Wegwerfprodukt aus Plastik oder Aluminium | 40 € | 40 € |
Differenz | -99 € | +27 € |
To calculate the savings potential, we proceed as follows: We look at the acquisition costs and the annual consumption costs.
In this example, the standard exhaust air filter costs approximately €40, making it a full €99 cheaper than the SETRENLO® solution. However, the operating costs are quite different.
Save up to €323 on consumables
A standard exhaust air filter costs approximately €40 per year to purchase. There are many different solutions available; we've focused on the more affordable ones. With more expensive solutions, the savings are even greater!
With the SETRENLO® exhaust air filter, activated carbon is included for the first three years. This means you don't have to worry about it again until the fourth year. One liter of SETRENLO® Vegan Activated Carbon, for refilling, costs €39 and lasts for another three years. This means you'll save €13 per year, saving €27 per year.
For the long-term analysis of cost savings, we consider a period of 12 years. With the SETRENLO® exhaust air filter, you can save a total of €323 in operating costs. The total cost, including the one-time purchase, is still €224.


The costs shown refer to the SETRENLO® - the green loo list prices as of February 9, 2025, and are subject to change. The market prices used for comparison do not refer to specific products, but rather to general market values. These, too, can vary considerably. So, just do the math yourself!
