Our Review Process

Water Filter Cast is committed to providing the most valuable and objective information about water filter systems and portable filtering equipment.

All our reviews are performed exclusively by professionals in the industry and reflect our best advice for you, the consumer. Our goal is to save you time researching products with the absolute best information we can create, and every review we write aims at being fair and impartial. 

Why Trust Us?

At Water Filter Cast, we strive to be perfect in everything we do. Before releasing an article, we devote our time to research and test each product ourselves whenever possible.

However, when reviewing whole house or under-counter filters, we do not have the budget to buy each product. Whenever this happens, our review process is as follows: 

  1. We choose a category (e.g. whole house water filter systems, whole house water softeners, reverse osmosis water filters, etc.).
  2. We thoroughly research each product from all available sources, including consumer product reviews, YouTube videos, and other sites.
  3. We supplement the study with the practical experience of those who have used the product. 
  4. At this stage, we select the best products in the category, aiming for the top 10 – some articles may feature fewer or more systems, based on our research.
  5. We write a detailed article that highlights the pros and cons of each product as well as a detailed buyer’s guide and FAQ section to help you decide which water filtration system is best for your specific circumstances.

Each product featured in our buyer’s guides has to pass through selection criteria. The process is constantly evolving, but this is how we do it right now: 

  1. We aggregate consumer reviews to determine which water filtration products are top-rated.
  2. Our experts assess each one of these products and select those that they consider the best in their category.
  3. We then move on to deeper research and real-life product testing.

To achieve our goal of providing you with the best possible advice, our experts install and use most of the water filtration systems we write about. Products in the same category are also compared head-to-head whenever possible. Our goal is to select only those systems that meet specific consumer needs.

In our buyer’s guides and review articles, we often use labels like “best overall,” “best rating,” “best budget choice,” and similar ratings. These labels reflect our personal opinion based on a general assessment conducted by our experts. The ratings often depend on:

  • Product quality
  • Water filtration quality
  • Installation ease
  • Pros and cons
  • General consumer opinion


At Water Filter Cast, we check all brand claims by testing each product ourselves whenever possible. We also conduct independent laboratory testing to check the water quality before and after installing a water filter system and consider general consumer opinions. Our final goal is to give you, the reader, fair, impartial, and expert buying advice.
