Four Seasons Filters was founded on a simple observation: St. Augustine's water quality varies wildly by neighborhood, and most homeowners have no idea what's actually coming out of their taps.
We started as a one-person operation and grew through word of mouth — because when someone trusts you with the water their family drinks, they tell their neighbors. Today we serve hundreds of homes and businesses across St. Johns County, and we still answer our own phones.
We don't sell the same system to everyone. We test your water, explain what we find, and recommend what you actually need — not what's most expensive.
We make it simple. No confusing jargon, no pressure — just clear answers and professional installation.
We come to your home, test your water quality, and identify exactly what's in it — and what's missing. No obligation, no hidden fees.
Based on your test results and your needs, we design a system tailored to your home — not a one-size-fits-all solution.
Professional installation by our local team, followed by ongoing maintenance and support. Clean water starts the same day.
"We had no idea our water was this hard until Four Seasons tested it. The difference since installing the softener has been night and day — our skin, our dishes, even our plumbing bills."
"Honest, professional, and they actually show up on time. They installed a whole-house system for our restaurant and the quality of our cooking water has never been better."
"They explained everything in plain English and never made us feel like we needed something we didn't. That kind of integrity is rare. We recommend them to everyone."
