It can get complicated to try and find the best product for your home considering the wide variety of in line water filters in the market, varying in construction, design, and filter medium.

In these cases, it will be best to conduct a water quality test from your local water treatment facility to monitor the specific elements present in your water.
From here, you can get a general idea of your specific water filtration needs. When reviewing in line water filters, make sure to consider these key factors:
-
- Filter medium
The first thing to take into account is the filter medium. The most popular filters by far are: granular, carbon-activated, and charcoal filters. Each of these different filters will have varying effectiveness levels and strengths. Some filters work best to eliminate chemicals, bacteria, and pathogens, while others are great at improving water taste and odors.
It’s essential to try and research the specific chemicals, substances, and impurities these types of mediums target. Carbon-activated and charcoal filters focus on removing carbon-based toxins and chemicals. They’re also widely used as effective physical barriers against harmful contaminants.
Granular filters are a well-rounded choice for homeowners that are looking for a filtration system that can deal with all sorts of issues.
-
- Filter rate
Water filter rate refers to how many gallons of water a system can treat in a single day. This is usually indicated by a number in GPD or gallons per day. From this, users can estimate how much water a system can treat during a period of time.
Filtration rate also gives the user an indication of the lifespan of their system – higher filtration systems are more expensive. Still, they will last longer and work better in larger households.
-
- Installation and maintenance
Make sure that the system you are buying has a user-friendly installation and maintenance system. Most filtration units will come with a comprehensive guide, so it’s best to go with a product that is convenient and hassle-free.
Most filtration units will require routine maintenance. Go with a convenient filter system that requires check-ups and maintenance only twice a year.
-
- Durability
Make sure to check the materials that your water filter is made from. Since chemicals and sediments will go through your filter, it’s particularly important to ensure that the construction is of high-quality.
Products that ensure low acidity will retain the structural integrity of your filter system. It will best if you also check your filter’s warranty to ensure you get the benefits of clean water in the years to come.
-
- Certifications
All water filter products will claim effectiveness and reliability. Take the benefit of the doubt by ensuring that these claims are backed by recognized NSF/ANSI certifications.
The more common NSF/ANSI certification standards include protection against bacteria, pathogens, and cysts. Ensure that the system is also certified to remove chemicals such as chlorine, mercury, and lead. Water filter systems also need to be certified to effectively remove unpleasant odors and flavors.
Conclusion
Investing in a high-quality in line water filter guarantees the safety and health of any household. Make sure to get a water filtration system that is specific to your water supply needs.
