\n\n A whole house water filter is a filtration system that treats water where the main water line enters your home, ensuring the water that flows from every faucet, every showerhead, and even in your washing machine, is clean and filtered. Whole house water filters are point of entry (POE) filters. They are gateways for your tap water, and allow only fresh, filtered water to flow to your faucets and appliances.\nWhat does a whole house water filtration system do?\nA whole house water filtration system can do exactly what you need it to do, meaning it can remove whichever contaminants you do not want in your home’s water supply. Depending on your home’s water source, you may want to reduce water hardness, to remove sediment, or to eliminate the smell of chlorine. Whole house water filters vary in complexity, but for whichever water quality problem you experience, there is a whole house filter that can provide the solution.\n \n\nWhat are the different types of whole house water filters?\nThere are five main types of whole house water filters: water softeners, ultraviolet purification systems, sediment filters, carbon filters, and acid neutralizers. Each filter addresses a different contaminant or water quality issue, so the right filter for you will depend on a thorough understanding of the composition of your water. Below you will learn about the five types of whole house filters, the contaminants they remove, and how you can improve your home’s water quality. Also, a home water testing kit or a lab water analysis are useful tools to determine what exactly is in your water and to help you choose the best whole house filter for your home. \n1. Water softeners\nA water softener is the solution if you have hard water, the most common water issue we face. Hard water is caused by a high concentration of dissolved minerals, specifically calcium and magnesium, and can wreak havoc in your home. If you have stiff, faded laundry, soap scum in your shower, or chalky dishes, you most likely have hard water. Hard water also causes scale that clogs your pipes, decreases water pressure, and shortens the lifespan of your appliances. Hard water can even affect your body, rendering your skin dry and itchy and your hair dull and frizzy. If your home is plagued by hard water, a whole house water softener is an investment that will ultimately save you a lot of money, as you will not have to pay for expensive repairs or replacements, such as your water heater due to scale build up.\nHow do water softeners work?\nWater softeners remove hardness-causing minerals through a process called ion exchange. Calcium and magnesium have positively charged ions, while the porous resin beads inside a water softener have negatively charged ions. Since opposites attract, when calcium and magnesium encounter the resin, they become trapped, allowing softened water to flow through. With proper maintenance, the average lifespan of a water softener is 15 years, so you and your home could reap the benefits of softened water for years to come.\nLearn More: What is Hard Water?\n\n\n2. Ultraviolet purification systems \nUltraviolet purification is the solution if you are concerned about the presence of living organisms, such as bacteria, viruses, parasites, and fungi, in your water. If using well water, in the event of a natural disaster, or if you are put on a boil water advisory, an ultraviolet purification system can ensure your access to safe, filtered water. Plus, ultraviolet purification systems do not use chemicals and do not waste water.\nHow do ultraviolet purification systems work?\nUltraviolet purification systems utilize UV light to damage the DNA of living organisms, rendering them unable to reproduce and unable to spread disease in the water supply. However, ultraviolet purification systems are most effective when water is first treated by a different filter, such as a sediment filter, because dirt and debris shield microscopic bacteria, viruses, etc. from UV light. Yet, when water is pre-filtered, ultraviolet purification systems can neutralize 99.9% of living organisms, making them a great addition to whole house filtration systems that give you peace of mind and safeguard your home water supply.\nLearn more: What is a UV Water Purifier and How Does It Work?\n\n\n3. Sediment filters \nA sediment filter is an effective solution to maintain a clean, refreshing water supply and to prevent damage to your home. Sediment filters trap and remove a myriad of contaminants from water, such as dirt, sand, clay, and rust flecks from aging pipes. If not addressed, sediment can clog your pipes, decrease water pressure, and damage your appliances, forcing you to pay for expensive repairs. Sediment can even make your water unsightly and cloudy: a condition called turbidity.\nHow do sediment filters work?\nSediment filters work through mechanical filtration, meaning they physically block sediment from entering your water supply. They have pores that are too small for particulate matter to pass through, but that allow water to flow through unhindered. A simple yet powerful concept, sediment filters are often the first line of defense for a whole house filtration system, as they improve the effectiveness of other water filters, by prolonging the life of carbon filters and water softeners, or ensuring UV systems operate at peak performance.\nLearn More: What is a Sediment Filter and How Does It Work?\n\n\n4. Carbon filters\nThe primary function of carbon filters is to remove chlorine from water, as well as its chemical taste and smell. Chlorine is used by municipal water supplies to kill bacteria in water and in water pipes. While still safe to consume, water that smells and tastes like chlorine is unsettling. Carbon filters not only improve the taste and smell of your water supply, but also the safety. With a carbon filter, you can be confident that you are not consuming harmful substances from your tap water, as chemicals like pesticides and herbicides are also significantly reduced.\nHow do carbon filters work?\nCarbon water filters contain activated carbon that has an abundance of pores along its surface and infrastructure. When water runs through the activated carbon, organics and chemicals are captured or altered by a process called adsorption, and clean water emerges on the other side. Activated catalytic carbon also facilitates the reduction of chloramines from your water. Chloramines, a disinfectant alternative to chlorine, are used by many municipalities to treat city water supplies. Chloramines are notoriously difficult to remove from water, but catalytic carbon can break apart the chloramine molecule with greater efficacy than standard activated carbon. \nLearn More: Activated Carbon Filters 101 \n\n\n5. Acid neutralizers\nAn acid neutralizer is the solution if you have acidic water. Acidic water has a pH of less than 7 and can cause serious damage to your pipes and appliances, including corrosion, leaks, and green-blue stains. Pure, neutral water has a pH of 7, but becomes acidic as it absorbs carbon dioxide during the process of precipitation. Therefore, many wells have acidic water since their supply is often from shallow groundwater. Chemical runoff can also cause acidic water, so it is important to protect your home and your health with an acid neutralizer.\nHow do acid neutralizers work?\nAcid neutralizers use calcite to decrease the acidity of water. Calcite is a mineral that is rich in calcium and is very high in alkalinity: the opposite of acidity. An acid neutralizer tank is full of calcite. When acidic water enters the tank, the calcite dissolves, neutralizing the water and raising its pH. A properly sized whole house acid neutralizer will raise the pH to neutral or higher and will prevent damages caused by acidic water.\nLearn More: What is Acidic Water and How Do You Treat It?\n\n\n \nWhat do whole house filtration systems remove from water?\nWhole house filtration systems remove a variety of contaminants from water and treat different water quality issues. Your home’s water quality will determine which contaminants need to be removed, and in turn, which filter is the best choice for your home.\nWater softeners remove:\n\nDissolved minerals that cause hard water – calcium and magnesium\nDissolved iron and manganese\nScale\n\nUltraviolet purification disinfects:\n\nBacteria\nViruses\nParasites\nFungi\nAlgae\n\nSediment filters remove:\n\nDirt, sand, and clay\nRust flecks from aging pipes\nTurbidity\n\nCarbon filters remove:\n\nChlorine\nChloramines* (If using catalytic carbon)\nPesticides and herbicides\n\n Trihalomethanes\nBad tastes and odors\n\nAcid neutralizers reduce:\n\nAcidity imbalance (low pH)\nAcidic corrosion\n\n \nWhole house filters vs. under sink and countertop filters\nWhole house water filters are point of entry (POE) filters, which means they are installed where the main water line enters your home and filter all the water that is distributed throughout your home. In contrast, countertop and under sink water filters are point of use (POU) filters. They attach to a single fixture, such as the kitchen sink, or are simply placed on the countertop, and only filter the water that you use in that specific place.\nWhole house water filters treat every drop of water in your home. The water you use to drink, cook, shower, brush your teeth, do laundry, and clean is all filtered. Your plumbing and appliances are also protected. Under sink and countertop filters are mainly used to filter the water that you drink, cook with, and maybe run to an ice maker in the refrigerator. Under sink and countertop filters are less expensive than whole house filtration systems, but they do not protect your pipes and appliances, and only provide one source of filtered water in your home.\nHow much do whole house water filters cost?\nThe short answer is it depends. It depends on the complexity of the filtration system that you need to treat your particular water quality issue. The long answer is the cost of a whole house water filter is between a few hundred dollars and few thousand dollars. However, keep in mind that whole house systems protect your pipes and appliances, so you will not have to pay for expensive repairs or replace your appliances as often. Also, most people spend between $400 and $1,000 on bottled water per year. A whole house filter eliminates the need to buy bottled water, so the benefits far outweigh the costs. If a whole house water filter solves your water quality issue and brings you peace of mind, it is worth every penny.\n \nWhat are the advantages and disadvantages of whole house water filtration systems?\nAdvantages of whole house water filtration systems:\n\nRemove a multitude of contaminants from water, customized to your specific water issues\nImprove the smell and taste of water\nExtend the lives of appliances\nPrevent damage to pipes\nGive you a higher level of peace of mind: Every drop of water that flows through your home is filtered. You can drink, cook, clean, and bathe with filtered water. Also, the water entering your home is disinfected from living organisms. If you have well water, this is a must. If you have city water, this is an insurance policy to protect your family if the city is unable to.\nEliminate the need for plastic water bottles: Less waste is created and avoiding single-use plastic is good for the environment.\n\nDisadvantages of whole house water filtration systems:\n\nInitial cost: Whole house water filters cost between a few hundred and a few thousand dollars.\nProfessional installation: Whole house water filters usually need to be installed by a licensed plumber, which adds additional cost.\nMay decrease water pressure: The water supply runs through the filter at a certain speed. If you are taking a shower, doing laundry, and running your dishwasher at the same time, you may notice a decrease in water pressure. However, if you already struggle with reduced water pressure, consider supplementing the filtration system with a water booster pump.\n\n\n \n\nDo I need a whole house water filter?\nYou may need a whole house water filter for a variety of reasons. If your home’s water supply contains a troublesome contaminant or generally poor quality, there is a whole house filtration system that can be the solution. If you are on well water, you may need to remove sediment and to disinfect your water. If you are on city water, you may want to rid your water of the smell and taste of chlorine. If you have hard water, you will reap countless benefits by installing a water softener. A whole house filtration system can be designed to remove anything that is troublesome from your water.\nIf you are only concerned about filtering the water that you drink and cook with, a whole house filtration system may not be the best choice for you. An under sink or countertop filter would make more sense and be more economical. However, if you want the peace of mind that the water flowing from all your faucets and through your appliances is safe and filtered, then yes, you need a whole house water filter.\n \nOur goal is for you to have a clean, trustworthy water supply that is kind to you, to your appliances, and to your home.
