Frequently Asked Questions (FAQs)

1. Are carbon block filters good?

Carbon block water filters are extremely effective in filtering out a variety of contaminants including very small contaminants or particle size. Water will generally flow slower during this filtration stage due to the compact nature of the compressed carbon.

2. Are carbon block water filters safe?

Are carbon water filters safe? Carbon water filters are safe, especially if they've been rated by a third party for material safety. All carbon filters are rated for CTO (chlorine, taste, and odor) removal, and sub-micron carbon blocks remove other contaminants like lead or cysts.

3. How long do carbon block water filters last?

Carbon filters should be replaced after 18-24 months of continuous (24/7) usage. Although this may vary depending on the company product, it has been shown that carbon filters can last for up to four years. These filters' lifespan is largely dependent on their carbon quality, use, humidity, and plant type.

4. Which faucet water filter removes the most contaminants?

Reverse osmosis systems are generally the most effective type of water filter. They can include more than seven filtration stages and use a reverse osmosis process that allows them to remove 99 percent of contaminants from the water, including chlorine, heavy metals, pesticides, and herbicides.
