A whole house water filter treats all the water dispensed in your house making it possible for you to have filtered water everywhere.

It is also good to know beforehand that the type of whole house water filter you get will depend on the contaminants in your water.

The type of whole house filter system you need - there are two types of whole water filter systems and you need to know each one of them to make a well informed decision. There is the heavy duty system and the second type is the standard capacity whole water filter system.

The most effective type is the heavy duty system. You should consider this type of a filter system because it has a long life span and you can change it after five years. It also requires less maintenance thus saving you a lot of trouble.

The standard capacity system uses water filter cartridge that need to be changed after every 6-12 months. However, this type has an added advantage in that you have the option of customizing your own filter. If you are worried about specific contaminants in your water system then you can have combinations of water filters that aim at sorting out those problems.

What to Look For

What size do you want?

You need to know the size of the whole house filter that suits you and your needs. For a longer service interval, a large filter is the most ideal. A large filter is also ideal since it has great pressure and thus more water flows through it. A filter size of 4.5" x 20" is ideal for most average homes but if yours is a large house hold you will need a big size filter with a port of 1 ½ and one that needs 25 gallons per minute (GPM) to help you meet the water demands in the house.

The Rate of Water Flow

The flow rate of water will determine the amount of water available in your household water outlets such as the kitchen, laundry, toilet, shower etc. the rate of water flow is measure in GPM ( gallons per minute). A quick calculation on demand ratings on your appliances and toilet will help you know the required flow for your household. Mostly, the rates range from 15-40 and will also depend on the size of your house and family. To avoid many inconveniences and disappointing occurrences you should make sure the rate is not less than 10gpm for a whole house water filter system. Normally, some of the flow rates for showers range from 2.5 to 5 gpm, 3 gpm for dishwashers, and 5 gpm for toilets.

The Life Span

The life a sediment filter will vary on the quality and quantity of sediments in your water. Compared to carbon filter cartridges, Stand-alone carbon filters that have carbon beds will only last much longer if they have a regular back wash system and have a backwashing valve installed in them. If you are using water supplied by the municipal, a whole house carbon filter of 4.5" x 20" will last you 100,000 – 150,000 gallons.

Size of The Port 

A whole house water filter should have a port of 1’’- this is the ideal size. This is size will not create any problems even if it is fitted in a ¾’’ pipe.

A micron is a unit of measurement, which is equal to 1000 of a millimeter. The rating of microns in a filter of any filtering system will determine its effectiveness. This means that is you are using a model with a filter rating of 1 micron then particles that are larger than 1 micron will not pass through the filter. Most whole house water filters have a micron rating of 1-5 microns.

To save you the hassle of having to hop from one shop to the other or one website to the other, we’ve gathered information and we hereby offer you the top three picks, according to us, for you to choose from.

My Whole House Water Filter Reviews

iSpring WGB22B 2 Stage Whole House Water Filtration System

this model is manufactured in the US by iSpring Water Systems. It filters any water supplied in your whole house and can remove up to 95% of contaminants, including sediment, rust, pesticides, and industrial solvents from your water. The system has filter cartridges that have an extended life and also lowers the chances of any reduction in the pressure of the water. It has a micron rating of 5 and is tested to meet the NSF/ANSI Standard. You should also know that the system has a two-stage filtration process where the first stage has up to 5 micron rating. The first stage is there as a defense mechanism for the water system since it filters dirt particles that are large enough to clog the following filter. The second stage has a carbon block filter made from coconut shells and has a 5 micron rating. This makes the system better than most in the market since the carbon used is finely ground and has a high density than the others. This makes it more effective in the removal of the contaminants in your water.
