Including filter system and high-performance Potassium filter.
Potassium is a naturally occurring mineral that can appear in well water and, less commonly, in municipal supplies. Small amounts are normal, but higher levels can matter for people who need to limit potassium intake for health reasons. Water picks up potassium as it travels through soil and rock, and it can also be affected by runoff or treatment chemicals. Because potassium usually has no noticeable taste or odor at typical concentrations, the only reliable way to know if it’s in your Orlando home’s water is to have it tested.
Many Orlando homeowners first learn about potassium when a lab report flags it while testing for sodium, chloride, or total dissolved solids. In water, potassium exists as dissolved ions, so it stays suspended rather than settling out. That means standard sediment filters won’t remove it, and many basic carbon “taste and odor” filters won’t either. If you want to understand potassium in your plumbing—especially important in Central Florida homes where biofilm and seasonal source variability can affect water quality—the best first step is a comprehensive water test.
To reduce potassium throughout your Orlando home, the most effective single-filter choice is a whole-house reverse osmosis system. RO uses a semipermeable membrane to reject dissolved ions like potassium rather than just filtering particles. Because potassium remains dissolved in water, membrane separation is generally required to lower it meaningfully. A properly sized whole-house RO treats water before it reaches kitchen and bathroom fixtures so every tap — from your Lake Eola faucet to outdoor spigots — gets the same treated water.
Whole-house reverse osmosis systems for Orlando homes are usually paired with prefiltration to remove sediment and chlorine or chloramines that can shorten membrane life. The RO membrane is what removes potassium, while the prefilters and post-stages preserve performance and cut down on maintenance. Because RO creates a concentrate (waste) stream, installations need a suitable drain hookup and space for the equipment. Mr. Pure Water can review your Orange County water test results, daily usage, and home layout to recommend an RO setup that reliably reduces potassium and fits your household needs.
