| | The whole house water filter unit is designed as a point-of-entry system that filters water directly as it enters a home plumbing system from a municipal or private water source. While not as immediately effective as point-of-use water filters, like counter top and Undersink filters that filter water directly before use, the whole house water filter provides clean, filtered water to every water source in the household. Ideally, this type of filtration system is used in conjunction with a counter-top or undersink filter in order to ensure the removal of lead and other elements that corrode from pipes after water enters the home’s plumbing system.
Most whole house water filters use a twin-stage filtration system in which most, if not all, harmful contaminants are removed from the water supply. The first stage of filtration removes any sediment materials in the water that may clog the filter, reducing its effectiveness. The second stage then uses filtration involve bituminous-activated carbon or/and coconut-shell activated carbon media to filter pesticides, remnants of biological matter, and other harmful chemicals.
By removing chlorine and other harmful chemicals at the point-of-entry, whole house water filters not only provide cleaner, healthier water, but better air quality, as well. They prohibit chlorine from vaporizing in the air when used in the shower and washing machine. Inhaling chlorine vapour is strongly correlated to the onset or aggravation of asthma and bronchitis. Whole house water filters also prevent harmful chemicals from embedding in clothing in the laundry, and they lessen the amount of detergent needed in both laundry and dishwashing. Most whole house filter systems sold in Australia use the 20 inch version of the standard type of housing which uses a cartridge with a diameter of around 70 mm (2.5") which is too small and seriously affects both pressure and flow, a 20" standard (70 mm) cartridge also falls well short for effective treatment as well as their rating is 7.6 litres per minute which is below the flow rate of a shower using a AAA rated shower head (9 litres per minute) let alone a normal shower that flows 15 litres per minute. These systems use what is referred to in the industry as BIG BLUE / BIG WHITE housing in their 20 inch versions, a 20 inch big blue/white will flow and treat at about 3.5 times the standard (70 mm) 20 inch cartridges and about 8 times the flow rates for the housings. The 10 and 20 inch big blue/white housings have a 0.2 psi pressure drop at 30 litres per minute, the cartridges and housing models below will drop the mains pressure less than 1.5 psi when the cartridges are in good condition using the Pentek RFC20-BB.

As you can see there is a huge difference between a stand size system and a big blue/white |  | Pictured here is a standard size 10" housing on the left, the centre housing is the 10" big blue/white and on the right is the 20" big blue/white housing. The 20" standard housing is the same as the 10" just twice as long and severely restricts water flow and pressure let alone in-complete treatment. The Big Blue and Big White are made by the same company with the Big White being the superior housing as it has a better O ring setup, the white versions cost more than their brother housings the Big Blue, specifications are the same for both.
