The whole house water filtration system is a device that connects to the main water line in your house and handles all the water running at every water tap. This is a more complex device than the regular under the sink or countertop water filters and offers a higher performance, which makes it a popular choice among homeowners. If you too are interested in purchasing a whole house water filter, here is what you need to know in order to choose a good unit.
Which impurities can the whole house water filtration system remove?
One category of water impurities that the whole house water filter can remove consists of sediments like dust, rust, sand, and dirt. These are commonly found in tap water coming through old pipes and are the main reason why people choose to install a water filter. Other impurities like chemicals, including the nasty chlorine, can also be removed with the help of a whole house water filter which can also eliminate heavy metals like iron and lead.
Which is the best flow rate of such a system?
The flow rate of a water filter is measured in gallons per minute or GPM and it represents the amount of water that can run through the water filter towards the taps and appliances in your house. A whole house water filtration system should have a flow rate above 10 GPM so that it will manage to deliver an uninterrupted water pressure. A flow rate lower than 10 GPM will keep you from enjoying a comfortable and satisfying water pressure that will allow you to use the shower and the dishwasher at the same time.
How large should the filter be?
The size of the whole house water filtration system determines the flow rate and the pressure of the water and is influenced by the port size. The ideal port size is 1” and for larger homes it can reach up to 1 ½” so the unit can carry enough water to ensure a good pressure. The ideal filter size for a medium size home is 4.5” x 20” with a port size of 1”.
The filter life is essential in choosing a good unit
A good water filter that will handle an average sediment level will last between 100,000 and 150,000 gallons before needing a replacement. A stand-alone carbon filter will last longer than a carbon cartridge only if you provide the filter with a backwashing valve and if the unit will perform a wash cycle.
