Is a whole house water filter worth it?
These systems offer exceptional performance and can provide cost and time savings versus point-of-use filters if you want filtered water from multiple sources throughout a home. It may be cheaper and easier to install a single whole house system instead of a combination of under sink, countertop, and shower filters. 
How long do whole house water filters last?
The lifetime of a whole house system depends on gallon capacity and usage, but a general rule is that a system will last one year for every 100,000 gallons of filtration capacity. For example, our Rhino® system will last for 1,000,000 gallons or up to 10 years (whichever comes first).
