Quality water is key to a healthy home. And while there’s endless filtration options available, some systems add chemicals or alter the taste of your water. The best carbon filters do the opposite, creating a deliciously pure flavor without the additives.
So, how do carbon water filters work?
This technology uses activated carbon to absorb contaminants in the water. The finer the grain of the carbon, the more absorbent the filter. This is measured in microns. Filters with a low micron level will typically have a slower flow rate, so the water spend more time in the filter. So, contaminants are more likely to be absorbed.
Depending on how often you use it, a typical carbon filter can last from three months to several years. However, this will differ with each product. You’ll generally need to change your carbon filter every three to six months, so it might be worth buying your filters in a multipack.
