The role of the faucet filter
The filtration effect of the filter is mainly related to the pore size - the pore size of the faucet filter is the largest among all filters and water purifiers. Therefore, its filtration accuracy is poor, and generally it can only filter impurities, color and other visible impurities in the water.
Calcium sulfate is directly present in tap water and can also be filtered out due to its bulky size - so install a faucet filter and you may find that the scale is smaller than before.
As for those ions, the filter does nothing. Therefore, the faucet filter can only reduce the scale, but cannot completely eliminate the scale.
How to prevent limescale
If you want to eliminate scale, you need water purification equipment with higher filtration accuracy - RO reverse osmosis membrane water purifier or ultrafiltration membrane water purifier. In these two types of water purification equipment, the main filter element has a very small pore size, so the molecular-level impurities can also be filtered out, so that the water has no scale.
Another method is to use chemical reaction filtration: use the ions on the resin to combine with calcium ions and magnesium ions in the water, so that the final water no longer produces scale (the process of water purification can be understood as the process of producing scale, The scale is produced in advance, and the water will not be produced again) - a device that uses this method to purify water is called a "water softener".
