Including filter system and high-performance Antimony filter.
Antimony is a naturally occurring element that can also be introduced through some industrial uses, and it can appear in drinking water as dissolved ions you won’t detect by smell, taste, or sight. Because it’s invisible at the tap, Marathon homeowners most often learn about it from a water test or a municipal report. Given our coastal environment in the Florida Keys and the mix of municipal and well or cistern systems here, treating at the point the water enters your home is a sensible step if testing shows elevated levels.
Any water entering a Marathon residence supplies every faucet, shower, laundry machine, and appliance, so antimony — when present — is a whole-house concern rather than an isolated fixture issue. Some residents pursue treatment after seeing changes in overall water quality; others prefer to act proactively based on lab results. In either case, a consistent, house-wide solution avoids piecemeal fixes and helps protect plumbing and appliances from dissolved metals and related issues that can be influenced by our tropical maritime climate and coastal salt air.
For reducing antimony throughout the home, a whole-house reverse osmosis system is commonly the single most effective filter type because its semipermeable membrane reduces many dissolved contaminants. Antimony in water is typically dissolved and will usually pass right through standard sediment filters, so RO’s membrane separation is what provides meaningful reduction. For Marathon properties—whether on municipal supply or a private well/cistern—installing RO at the point of entry gives you broad protection across every tap and fixture.
A correctly designed whole-house RO installation includes prefiltration to protect the membrane from sediment and particulate that are common in coastal and storm-affected areas like Marathon. Those prefilters preserve membrane life and steady performance while the RO stage handles dissolved metals such as antimony. Regular maintenance—timely filter and membrane replacements—is important to keep removal levels and flow rates where they should be.
