When it comes to water filters, it's important to understand that not all brands are created equal. Second Nature's It Matters filter, for example, is certified to meet NSF 53 and 42 standards, and is able to leak more than 99% of lead from drinking water.

The most basic certification a refrigerator water filter can obtain from NSF certifies that your water filter improves both the look and overall taste of your home water supply. However, there are several NSF certifications that your refrigerator water filter was tested for, and they all mean slightly different things. For example, a PureSource filter can earn a total of three NSF certifications if it's large enough to filter 200 gallons. With a lead-free food-grade material construction and a top-of-the-line coconut charcoal block and three-layer filtration system, you can count on this filter to provide clean, healthy drinking water for you and your family. In many cases, taking a risk with generic brand filters is worth it as they tend to be much cheaper than OEM products.
