Big Blue Whole House Water Filter Systems come in 10" and 20" hieght and in single, double and triple filter configurations. The 20" Big Blue Whole House Water Treatment System will give double the flow of the 10" at the same pressure drop. Housings are available with 3/4", 1" or 1 1/2" connections. WHY BIG BLUE SYSTEMS ARE BETTER
Customers who have purchased a standard 2 1/2" by 9 7/8" filter from retail chain stores often call and complain about short filter life and low flowrate.
The formula for volume of a cylinder = PI*r squared.
A standard slimline water filter is 2 1/2" in diameter while a big blue filter is between 4 1/2" and 4 5/8" in diameter.
A slimline filter has a volume of 4.9 cubic inches.A 4 1/2" Big Blue filter has a volume of 15.9 cubic inches,nearly three and a half times the volume!!
That equates to over triple the filter life and flowrate.
