Water Filter IQ

Our Testing and Data Gathering Methods

WaterFilter IQ prides itself on providing the most accurate and up-to-date information on the latest water treatment products on the market.

In-House Testing

Many products featured and recommended on our website were tested by us in our facilities. We use a variety of water testing kits, including highly sensitive TDS meters, pH meters, composition kits, freeze testing, timers and scales to name a few.

It’s important to note that while we use commercially available products to test various water filters, we are not scientists or engineers and our test results are for educational purposes only.

NSF Certifications

We rely on authoritative governing bodies, such as NSF, to supplement our findings. We’ve carefully cross-referenced all water filters in the market with NSF certifications to ensure their claims are justified and backed.

Verified Customer Reviews

We read and analyze hundreds of thousands of verified customer reviews to get an accurate view of the product. Not all products are suitable for all people, and thus a single review will not be the most helpful when deciding on a water filter. We carefully interpret the different types of people who will use the product and display it in a digestible way. We only take a review into consideration if it is a verified purchase on a trusted online marketplace.
