What is whole house water filter?

A whole house water filter is a device that is installed directly to the main water line of your household. By doing so, it ensures that all of the tap and shower water throughout your entire home becomes filtered. This means that you will no longer have to worry about purchasing separate filters for each individual faucet in your home.

Most Common Types of whole house water filter:

  1. Water Softener: Water softener cartridge removes the excess calcium & magnesium ions from your water supply. This is usually done with an ion exchange process, which uses potassium or sodium-based chemicals to separate the calcium and magnesium by exchanging them for other positive ions.
  2. Water Filter: A filter cartridge is a cylindrical mesh of fine filtration material – such as activated carbon and zeolite – compressed between two end caps and installed within a housing assembly. They remove high levels of chlorine, dirt, sediment, and other impurities from drinking water supplies often not removed by boiling (for example Cryptosporidium parvum). Most filters can be disassembled for cleaning and replacement of cartridges. Faucet mounted filters are easy to install. They are useful in iron removal, but do not remove other heavy metals.
  3. Carbon Water Filter: Carbon water filters (also known as activated carbon or granular carbon) use a bed of activated carbon to remove chemicals and other contaminants by adsorption. Carbon filters are often used for refrigerator ice makers, whole house tap water filtration systems, aquariums, and hydroponics. They are also used as part of koi pond filter systems.

Carbon-based home drinking water treatment devices usually only remove chlorine and aesthetic related impurities such as iron, sulfur smell/taste and turbidity from the water supply – but do not treat it with disinfectants.

  1. Ultraviolet (UV) Water Sterilizer: Ultraviolet water sterilizers use a lamp that emits ultraviolet light at a specific frequency to kill or inactivate harmful microorganisms. These systems can be point-of-use water treatment devices, with lamps attached directly to the faucet, inline within a flexible plastic tubing loop inside a storage tank, integral UV lights installed on the side of holding tanks etc., or whole house units which supply treated water throughout your home.
  2. Reverse Osmosis (RO): Reverse osmosis (often abbreviated RO) is a process where contaminated water is forced through very small filters under high pressure (tightly against reverse osmosis membrane). Contaminants are trapped in the filter leaving an almost perfectly pure product on the other side. Reverse osmosis is very common in household applications for purifying drinking water, but it is also used in industrial applications, to pre-treat waste streams before they are discharged to rivers or oceans.
  3. Kinetic Degradation Fluxion (KDF): Kinetic Degradation Fluxion (also known as KDF water filters) use a copper-zinc formulation to remove chlorine and reduce iron, hydrogen sulfide, lead and mercury. A second stage of media filter is usually added for fine filtration.

Factors to Consider before buying whole house water filter

Capacity: A whole house water filter’s capacity refers to how many gallons it can treat before needing to be replaced or cleaned. Since these filters are used in homes with multiple people, it may need to be replaced every few months depending on the local water supply. Be sure that you choose a unit that will sufficiently suit your family’s needs and ensure that you don’t run out of filter media before it’s time to replace the whole house water filter.

Filter Cartridge: Whole house water filter cartridges are typically made of carbon and can be either granular or block activated carbon (GAC or AAC), like those found in faucet mounted filters, carafe style water pitchers and countertop units. Other common cartridge types include KDF, ceramic and sediment cartridges. Some specialty whole house filters use ultraviolet germicidal irradiation (UVGI) instead of a carbon cartridge as their final stage filtration method.

Certification: The NSF International certification ensures that products meet certain standards for contaminant reduction claims, material safety and performance criteria set by NS/ANSI 42; National Sanitation Foundation/American National Standards Institute. Be sure to look for certification on the whole house water filter and cartridge to ensure that your family is drinking safe, clean water free of excessive chemicals and other harmful substances.

Filtration Media: Some designations you may see on a whole house water filter include “GAC,” “AAC,” and “Ceramic” (or simply carbon), which refer to the type of filtration media used. These types of cartridges are typically made from granular activated carbon, block activated carbon or ceramic respectively. Although GAC and AAC have been proven effective at removing chlorine from tap water, they don’t do anything to remove chemical pollutants found in many municipal supplies today such as pesticides and herbicides.

Installation: Most whole house water filters require professional installation to ensure that the unit is properly set up and connected to your home’s plumbing system. However, there are some do it yourself systems available on the market today as well as pre-installed units for those who don’t want to mess with installation themselves.

Price: There is a wide range of prices when it comes to whole house water filters depending on their type, filtration capacity and whether they come with a cartridge included (some can be used with standard 10″ filter cartridges). While the cost of these units may seem prohibitive at first glance, remember that they last several years before requiring replacement compared to most faucet mounted and pitcher style filters that must be replaced every few weeks or months.

Type of Filtration: Whole house water filters can offer filtration through several different types of media depending on the unit’s design – some cartridges use granular activated carbon while others require block activated carbon or an alternate type of filtration media. While it is important to drink safe, clean water free of harmful chemicals and contaminants, this decision will be based on your specific needs.

Household Size: Smaller homes with low daily usage requirements should select an appropriately sized system, which is typically determined by flow rate per minute (gpm). Medium to large homes with high water usage levels should choose a system that can process at least 6-7 gpm while smaller homes should only require 3 gpm systems.

Design:  There are several different designs for whole house water filters, including countertop units that sit on the kitchen sink or under-the-sink units connected to your cold-water supply. These usually require either a direct connection to the incoming main line coming in from the street or they use something called a “well point,” which is basically an open pipe that reaches down into your well casing for raw tap water.

Water Pressure: Most whole house water filter systems can be installed with up to 80 psi of incoming home pressure without causing damage to its components. However, it is important to note that if you have very high-water pressure (above 150 psi), using one of these types of filtration units will most likely result in lower flow through rates and slower processing.

Materials:  The materials used in these types of filters are extremely important since they play a role in determining the length of time the system will last, resistance to corrosion and impact damage as well as its overall effectiveness. Some units use plastic for their cartridge housings while others rely on metal such as stainless steel or even titanium alloy.

Warranty:   The warranty included with a whole house water filter is an important factor in determining whether it provides good value for your money. Most of these units include a limited lifetime warranty that covers defects in the manufacturing process, while others offer either one or multiple year coverage.

Usage: Many homeowners prefer to use whole house water filters because they can provide safe drinking water from every faucet throughout the entire home without having to worry about running out of clean water anytime soon. Some people also use these systems for ice making and food preparation since they effectively remove any contaminants found in household tap water – this helps create a safer environment, especially when you have small children or pets around the home frequently.

Durability:  When it comes to choosing the best whole house water filter, you should focus on how long each unit can last before needing replacement. Depending on the type of filtration media used, some cartridges will need to be replaced every few months while others can go if a year before they need to be swapped out. The quality of these units is essential if you want them to provide optimal protection from contaminants without leaking or breaking down.

Plumbing: If your home already has a tankless water heater installed for taking hot showers and doing laundry, then a whole house filter system should not interfere with its operation at all. However, if your water heater requires high flow rates (above 7 gpm), then you will have to choose one that has this capability or else it will not be strong enough to provide you with the water pressure that you require.
