If you do not yet worry about the quality of water you at your house, then now is the time to start. According to the Centers for Disease Control and Prevention, public water exposes you to numerous physical, chemical, biological, and radiological contaminants, all of which the health of you and your family at serious risk. Water filter systems clean your water of these hazards, making it safer to drink.

Once you realize the danger municipal water puts you in, you will likely want to filter it. However, options can be overwhelming. Products are literally flooding the market, with various filter models available from different brands using multiple filtering technologies there seemingly just to confuse you. Do not despair, though. Look for these five factors in your water filter, and you will be good to go:


The reason everybody installs water filter systems is to purify their water, free it of the many contaminants present in it. You want safe water, and your filter must provide. It must filter out all that is unsafe, from parasites to bacteria, cysts, even pharmaceuticals. Several studies show household water causing high cholesterol, hormone suppression, obesity, and more, and it contains carcinogens too.

Before you buy the first water filter you come across, take your water to a certified laboratory for testing. Results will tell you exactly which contaminants are present, and ultimately which water filter has the capacity to remove them. Most filter approximately 40 impurities, others as many as 60 contaminants, and still others as little as just 25 pollutants. Testing your water first is paramount.


Few people know to consider the maximum daily rate of filtration when looking at water filtration systems. However, this is crucial. Maximum filtration rate is the quantity of water a filter can clean each day. If you use more water daily than a filter can filter, then it might not be the best choice for you. Not all filters are equal. The maximum filtration rate differs significantly between them.

For water filter systems to work, they must be able to filter more water than you use. However, you do not need a filter that cleans way more than you consume either, as that is just wasteful since the more water a filter can clean, the more expensive it is. Work out how much water your household uses every day, and then get a water filter with a maximum filtration rate that can handle it.


You do not only want to remove contaminants from your water. You also want to improve its overall quality. This includes eliminating foul odors and tastes from it, as well as maintaining the correct pH balance and preserving any good and healthy minerals. Reverse osmosis water filter systems work well for improving water quality, but this is not true all of the time, since they also remove good minerals.

Calcium, sodium, iron, and magnesium are but a few of these natural minerals. Your body needs them. If deficient in minerals, you could suffer issues with joints, bone density, gastrointestinal function, and even cardiovascular health. It also makes the water acidic and tasteless. Active carbon filters preserve minerals and work well, but if contaminants are overwhelming, you might need re-mineralization filters.


The water filter you buy will influence your budget significantly. Many factors decide the cost of water filter systems, including how many stages it goes through to process water, storage capacity, filtration rate, and more. Additionally, if you need re-mineralization cartridges, costs will skyrocket further. Besides initial setup costs, there are other expenses involved with having a water filter.

Cartridges need regular changing, so know what they cost. Consider how much energy water filter systems use and add that to your electricity bill. Remember, however, that filters that seem pricy on first purchase may actually work out cheaper over the long-term. Having healthy water does not require the most complex, expensive system, just what you need to remove impurities under your usage rate.


You will need to maintain your water filter, no matter which one you choose. Replacing cartridges is necessary, and your instruction manual will tell you how often to do this. Look for filters that do not require changing too often. You will also need to monitor your water filter systems somewhat, depending on the type of you buy. Complex water filters need more time and money to maintain.

For example, a six-phase filter for reverse osmosis will need several cartridges changes, and at different times too. To ensure filter durability, you also need to pretreat feed water. In cases of hard water, you need water softeners to prevent mineral deposits in parts of the filter that cause severe scaling. You will need to care for your water to ensure it works, so choose one that needs less or easiest maintenance.


The health and wellbeing of you and your family rely heavily on choosing good water filter systems. Before installing one in your home, spend time researching which ones will work best for you. Besides thinking solely of its fundamental functions, it would be wise to consider other factors. There is more to just filtering the water, so think of purity and healthy first, or perhaps later regret your choice.
