Otherwise, you should find information on how many gallons of water a filter can produce per minute, or per day. Finally, you should use the data from points 1, 2 and 3 to find a system that meets your requirements for contaminant removal, flow rate, and filter capacity. When you find a system you like, do your research and read up on customer reviews.
If the product has a good reputation, you can consider making a purchase. Most whole house filters are designed for municipal water supplies, and can remove common city water contaminants, including chlorine, pesticides and lead. Test your water in advance to find out which contaminants you need a filter to remove. If you get your water from a private well, these filters are a better choice for you. The longevity of a filter usually depends on the manufacturer and quality of the product.
Different filter types may last longer than others. Generally, pre-sediment filters have the shortest lifespans, as they can become quickly clogged with large particles. Most pre-sediment filters need changing after about 3 to 6 months. Carbon filters and remineralization filters for adding healthy minerals to water have an average lifespan of 6 months to 1 year, depending on filter use.
Read up on a product to learn when the filters require changing. Some of the best whole house water filter systems contain more filters than others. Not all whole house filters remove the same contaminants. While most will target chlorine and lead, some are capable of removing hundreds of contaminants, while others can remove less than This can give you a breakdown of the different elements in your drinking water.
Another way to find out the quality of your water is to test yourself using a water test kit. Your household water system will need to be installed somewhere, which means having free space for connecting a whole house water filter to your main water line.
A micron is a unit of measurement, with 1 micron being equal to a millionth of a meter in length. So, for example, a 5 micron sediment filter will be able to remove particles as small as 5 microns, or a 1 micron filter filters up to 1 micron in size.
You should be able to find the micron ratings of a particular filter in its product information. As all particles are variously sized a micron filter rating will give an indication of the types of particles it will remove best.
Household water filtration systems that consist of a larger variety of filters tend to be the best high quality water filter option for removing the largest quantity of contaminants from city and well water, because their filters are designed to remove particles at different micron sizes. Some whole house filters are more expensive, and you may need to pay more for features like remineralization filters or a UV filtration option for water purification.
You can also use a UV filtration device with a RO system. Carbon whole home water filter systems benefit from a slower water flow, as it allows the filters to more thoroughly remove particles from water. This type of filtration requires adequate water pressure to force water through the RO membrane at a sufficient rate, making it not so environmentally friendly.
Certification proves that a filter works to the standards as advertised by its manufacturer, whether you plan to use it for city municipal water or well water. No matter what type of whole home filter you opt for, a good warranty is essential.

How much do certifications really mean? Filters have finite filtration capacity — they can only remove so many contaminants before the filtration media is spent or mechanical filters fail. As a general rule, sediment and carbon filters last 3—9 months depending on water quality — the more contaminants they filter, the shorter their lifespan. Extra-capacity filters last longer, and reverse osmosis membranes last 2—5 years. Multi-stage systems using more than one type of filtration require maintenance at difference intervals.
When you consider the cost of a filtration system, factor in the price of replacement filters. Sub-par carbon and sediment cartridges are cheap but need to be replaced more often. Better filters cost more upfront but last longer and require less maintenance. Knowing what could be in your water is scary.
Multi-stage systems using sediment, carbon, and KDF filters remove the most contaminants, including dirt, rust, chemicals, heavy metals and more. Designed to filter large quantities of water on demand and without reducing water pressure, the only difference you should notice is that your water looks, smells and tastes better. Since prices are similar, a whole house water filter may be a better value if it removes target contaminants.
But it could contain traces of pharmaceutical residue and chemicals as well as lead from aging pipes. Fluoride is added to most municipal supplies to promote dental health despite some evidence it could be harmful, and disinfectants like chlorine and chloramines can make water taste bad.
Both city and well water can have excessive minerals — known as hard water — and that can damage pipes and appliance.
Well-water test kits are available at hardware stores or send a sample to an independent lab. The important part is to test your water and choose a system that reliably removes the unwanted substances that are unique to your supply. Most whole-house filters are larger than undersink versions and need to be installed close to the point where water enters your home. Water capacity is the maximum number of gallons a filter can process before cartridges need to be changed.
Always check the capacity for each one in the system — some have multiple filters that need to be changed at different intervals. As a rule, the larger the total capacity, the less overall maintenance is required. Flow rate — measured in maximum gallons per minutes — tells you how fast a filter can process water. Flushing a toilet and showering simultaneously use an average of six gallons per minute combined, so to do that or comparable water-using activities, a flow rate at least that high is essential.
The Aquasana EQ Whole House Filter System, for example, offers comprehensive filtration plus softening with a flow rate of seven gallons per minute — the lowest on our list. Evaluating the quality of a cartridge is difficult because performance ratings are based on average water conditions. Five filters can each claim a percent reduction of lead, but if your water has higher levels than average, performance between them may not be equal.
In this case, cartridges made with more advanced media might perform better. Specifications are helpful, but not ironclad. The number of cartridges in a system can also affect its overall efficiency. No filter on our list is an actual water softener, but three have some softening capability that protects appliances.
The price of filter replacements and the frequency at which they need to be changed makes some systems less expensive to operate over the long haul.
However, there are many impurities that, while not harmful to your health, make water unappetizing to drink or cook with. Most people who choose to filter their water do it to enhance taste, not safety.

For drinking water in the U. However, there are still times when you may want a system that can filter out contaminants, like lead or man-made chemicals. If you are on well water, have old pipes, or live in an area with unsafe drinking water, you may need a water filter to remove contaminants like lead or actual particles like sand.
If you are on city water, you can look at the annual water reports to see what kinds of contaminants are in that water. Even if your municipal water is safe, you may have old pipes that could be leaching contaminants into your water. Adding a water filter can help remove those impurities.
Filters certified to remove chlorine, for example, can also encourage hydration by making water more enjoyable to drink.
The NSF is one certifying body. For example, the NSF offers certification for removing a certain amount of chlorine and a separate one for removing lead. The more certifications a filter has, the more contaminants it can remove. An earlier version of our list included several water filters that were removed based on similar language that made it unclear whether they were independently tested.
A smaller pitcher for a dorm or apartment, for example, may be fine, but for larger households or if you want to filter water for cooking as well as drinking , faucet or under-sink filters, may make more sense.
