FAQ
How long do whole house filters last?
Most whole house filters treat 100,000 to 1,000,000 gallons. For an average household using 100 gallons per day, a 1-million-gallon filter lasts about 25 years - though sediment pre-filters need annual replacement.
Do whole house filters reduce water pressure?
Quality systems like SpringWell CF+ (9 GPM) and iSpring WGB32BM (15 GPM) have minimal pressure impact. Cheaper systems with low flow rates can cause noticeable drops during peak usage.
Can I install a whole house filter myself?
Yes - most systems including SpringWell and iSpring are designed for DIY installation. Budget 2-4 hours for the job. SpringWell provides video installation guides.
