There are many great water treatment options out there. While no system is perfect, each system does have some major benefits. Here is a guide to the types of water filter you should choose, based on your most important criteria.
Most Accessible/Lowest Startup Costs
If you're looking for a filter that's easy and low cost to install, then you might start with a water pitcher. It can't get much simpler than filling a pitcher with tap water and waiting a few minutes for it to filter. This way, you can side-step the need to hire a plumber to install a new system. This is a great option if you're just testing the waters of water filtration, or if you're in a temporary location where you don't want to invest in a permanent water filtration installation.
Many people are looking for a filter that's easy to maintain; once you get it in place, you don't have to worry about it too much. Reverse osmosis filters are a great option for these people. The reverse osmosis process works by using a series of mesh filters with tiny openings that allow water particles to flow through, but not much else. If there are any heavy metal particles luring in your water, for example, they won't be able to pass through the tiny openings in your reverse osmosis filter.
Once this system is installed, it requires little maintenance. There are no chemicals to refill, and the system is built to last.
Some people are most concerned with the thoroughness of their water treatment system. For these people, a multi-stage filter is a great option. There's no set formula for designing a multistage filter and it will depend on the type of contaminants that are present in your area. But, for example, a multi-stage filter might include UV light components, physical separators such as reverse osmosis filters, and even chemicals to remove particles from the water. For this type of filter, you'll want to check with your water filtration technician to determine the best system for your budget. These systems require a bit more design and installation, but they can be worth it to improve the quality and safety of your water tremendously.
So, to sum it up, your recommended water filter depends on what's most important to you. Whether you value cost, simplicity, or water safety the most, there is likely a filter option out there that works for you.
