An aerator is a small component installed on the tap in bathrooms and kitchens.

Certain aerator models reduce the flow rate, thus saving water.

What does an aerator do?

A regular aerator mixes the water stream with air, creating a soft, splash-free water stream. It thus improves the stream comfort, ensures more hygiene, and prevents annoying splashing, for example.

In addition, a water-saving model reduces water consumption and thus leads to a reduction in energy costs. Because if you use less hot water, less water is heated and therefore electricity, gas or heating oil can be saved.

Where are aerators used?

Nowadays, every tap is equipped with an aerator – but not all of them with a water-saving one. At the washbasin and in the guest toilet, it makes sense to choose an aerator with the lowest possible flow rate. There, unlike in the kitchen, only a small amount of water is usually used – for example, for quick face and hand washing or brushing teeth.

Water can also be saved in the shower. The product used there, however, is not an aerator, but a so-called flow regulator. These are small, flat, round components that can be inserted by the user in a few simple steps.

Very important: aerators and flow regulators must not be installed if pressureless water heaters or storage tanks such as boilers are used in the household.

A new, water-saving aerator is always useful when you want to save water and energy in everyday life in a simple yet effective way. This applies toprivate households, but also to public facilities or businesses such as restaurants and hotels.

How much water can an aerator save?

An aerator can reduce water consumption by up to 50 percent. This means that you only need half the amount of water while maintaining the same level of comfort.

How much money can an aerator save?

The savings from a new, water-saving aerator depend on the amount of water reduced and the respective energy costs. So, if we assume that you equip your kitchen tap and the bathroom tap with a water-saving device, you can save about 50 euros per year in water and energy costs per person. In practice, this means, for example, that a four-person household can save almost 200 euros per year in no time at all.

How much does an aerator cost?

Replacing an aerator is usually very inexpensive. Most aerators cost less than 10 euros. The best thing about it: you can remove the old aerator yourself and attach the new one in just a few steps, without special installation tools or the help of professionals.

Thanks to the energy and water costs saved, this small investment pays for itself very quickly.

Which aerators are there?

There are many different types of aerators, differing in size, material, flow rate and spray pattern. It is important to choose the right aerator for the respective tap if you want to replace your old one with a new, water-saving model. 

The bottom line

Water-saving aerators may be small and inconspicuous, but they can be a real game-changer. With an investment of just a few euros, you can cut your water consumption by half and reduce your energy costs at the same time.
