Faucet Filter Cleaning: Maintenance Guide

How to remove limescale and sand from faucet filters in a few simple steps

Faucets spraying water everywhere: it's a common problem that happens to everyone sooner or later. The most frequent solution is to replace them with a new one, but there is a much simpler and more economical alternative: regular filter maintenance keeps them in full working order.

First, you need to remove the filter from the faucet by unscrewing the filter holder by hand or using the specific wrench provided, in the case of faucets without an external filter holder.

If the filter holder is stuck due to limescale, use a pair of pliers wrapped in a cloth to avoid scratching the chrome finish.

Once removed, clean it from sand and residue with a stiff-bristle brush. Some models can be completely disassembled: inside you will find metal mesh screens that should be carefully cleaned one by one.

Now submerge the components in a small container filled with liquid descaler — the kind used for household appliances will work perfectly — or simply use white vinegar. The goal is to completely remove every trace of limescale.

Let them soak for at least 3–4 hours; if they are not perfectly clean, repeat the process by replacing the vinegar or descaling solution with fresh product. Reassemble them on the faucet: they will work like new, without any need for replacement.

Aerator filter: what it is and why it should be kept clean

Aerator filters serve to reduce water consumption: they mix air and water in the stream, maintaining an excellent washing effect while using much less water. Due to their structure, they are the most susceptible to limescale buildup, but they too can be easily cleaned by following the procedure described above. Better not to waste: not only water, but also filters.

faucet filter flow rate

Not everyone knows that the water flow rate of the filter changes depending on its color, so if it seems like too little water is coming through, replace it with one that has a higher flow rate.
