If you are looking for the best whole house water filters, I would suggest you to do some research first, since not every whole house water filter is created equally and not every filter will fit your needs properly. However, I would strongly recommend everyone to install a whole house water filter, since it is one of the best investments you can ever do, and it will keep you and your family safe. But what is a whole house water filter exactly?
Well, a whole house water filter, is a filtering system that is installed in the earliest point possible where the main water line of the city or your district enters your house. By installing this at the earliest possible point you filter the whole water source of your house properly, including all your taps, appliances and so on. This means that one water filter is enough for all your house, even if you have multiple water heaters, you just need one whole house water filter to supply all your house with filtered water.
However, you should be a little cautious before buying one since there are a wide variety of systems available, including carbon-based, reverse osmosis, and some extra advanced next-generation filter systems.
The most popular is the Carbon-based whole house filter system which is also the most affordable and easier to maintain compared to any different type of filter system. As a matter of fact these kinds of whole house filters cost under $1000 generally and on average on system will last you about 300,000 gallons of water before the main tank needs to be replaced, and the average household in America consumes about 100,000 gallons of water annually, meaning that it will last you about three years. They remove a lot of harmful chemicals from your water, such as rust, sediment, and other large contaminants, lead, mercury, nickel, and other carbon compounds, or organic materials that are very harmful to you.
Reverse osmosis whole house filters are also available, which are extremely effective at removing harmful contaminants than carbon-based systems. However, these are also very expensive and require large water storage tanks, at least at 200 gallons to perform properly, and also are expensive to maintain.
Those advanced next-generation technology whole house filters combine the best of both worlds, surpassing the performance of both, without producing wastewater and without removing the beneficial minerals, also without raising the costs and maintenance price of the system. However, these systems are not widely available and you can’t find them everywhere.
Besides those aforementioned systems, you will also find systems that are designed for specific problems such as for those that use well water and many more.
