Water filters are designed to resolve problems associated with harmful contaminants in water. Bad taste or smell can make water unsuitable to drink, or a high concentration of chlorine in water can make you itch or have scaly skin after you shower.
So, if your goal is to improve the quality of your water and to have a better tasting and healthy drinking and shower water, this site will guide you to choose the filtration system that best meets household or commercial needs.
Your First Step?…
Before a home or a commercial outlet decides to buy a water filter system, the first step is to test the water to find out exactly what the exact contaminants in order to choose the best water filter.
Even if you are making a homemade filter, knowing the contaminants will help you buy the right parts. You can find affordable self-testing kits on the market. For example, a lead test costs less than $20; you can get a good test kit for almost the same amount or less.

Even if you hire a laboratory, a portable in-home self-testing kit can give you the same results at far less cost. After you have confirmed what’s in your water, it’s easy to find the best filtration systems that are certified to remove or reduce that specific contaminant in your water without getting scammed.
How to select the right home filtration
There are two ways to install a water filter namely the point-of-entry (POE) systems which treat water as it enters a home or a commercial outlet; and a point-of-use (POU) which is installed at a location where the water will be used such as kitchen faucet, shower head, and refrigerator.
Examples of POE systems are whole house filtrations, and whole house softening units. The POUs include countertop water filters, faucet mount, under sink, pitcher/carafe, refrigerator filter, and shower head filters.
The best treatment systems are the ones that have been tested and certified by the National Sanitation Foundation (NSF) International. NSF is an independent organization that tests and certifies filters for performance.
Certifications provide some level of confidence that the units you are about to buy can do what the manufacturer says it would do. The filtration system you choose should provide a statement that lists exactly which contaminants the filter is certified to reduce under which NSF/ANSI Standard.
For instance, Standard 42 is for Aesthetic Effects or “taste and odor,” Standard 53 for Health Effects, like Cryptosporidium, lead, volatile organic chemicals (VOCs), and disinfection by-products, Standard 177 for chlorine in a shower head.
