Activated carbon filters, a popular type of water filtration system, work by using adsorption to remove impurities and contaminants from your drinking water. As you consider using an activated carbon filter, you might wonder how it benefits the environment.

The good news is that these filters have a relatively low carbon footprint, making them a more eco-friendly option.

When it comes to filter maintenance, you'll need to replace the activated carbon filter regularly to guarantee it continues to remove impurities effectively. Failing to do so can lead to a buildup of contaminants, which can negatively impact the taste and quality of your water.

Reverse Osmosis Systems

Reverse osmosis systems, a popular choice for homeowners, use a semi-permeable membrane to filter out impurities from your drinking water, providing you with a reliable source of clean water. By applying pressure, the system forces water through the membrane, removing up to 99% of contaminants, including dissolved solids, bacteria, and viruses. This results in water that tastes fresh and clean, perfect for drinking, cooking, and even making coffee or tea.

To guarantee your reverse osmosis system continues to perform at its best, regular system maintenance is essential. You'll need to replace the filters periodically, as their lifespan varies depending on usage and water quality. Typically, pre-filters last 6-12 months, while the semi-permeable membrane can last 2-3 years.
