At Donovan Air, Electric & Plumbing, we help homeowners throughout Jacksonville and Northeast Florida better understand their water and take steps to improve it. Whether you’re dealing with hard water, chlorine taste, or exploring reverse osmosis systems, these FAQs break down what you need to know about water quality and filtration for your home.
Water quality refers to the chemical, physical, and biological characteristics of water, as well as its suitability for specific uses, such as drinking, cooking, bathing, or appliance protection. Good water quality means water is safe, clean, and properly balanced, with minimal contaminants and pleasant taste and odor.
Water quality is commonly evaluated in four categories:
A comprehensive water test looks at all four categories of water quality to give you a complete picture of what’s coming out of your taps. It checks how your water looks and tastes, what minerals and chemicals are present, whether bacteria or other microorganisms are present, and whether any regulated contaminants are detected. This ensures your water treatment system is designed to address your specific water issue.
“List 1” typically refers to primary drinking water contaminants regulated by the EPA. If your water contains List 1 contaminants, a water filtration system is strongly recommended. List 1 contaminants that can directly impact health include:
In the Jacksonville area, homeowners often deal with:
Water quality solutions should be tailored to local water conditions and your home’s plumbing.
The healthiest option depends on your water source. However, for most homes, the following options improve safety, taste, and balance:
Yes, reverse osmosis water is very safe to drink. RO systems remove up to 99% of contaminants, including lead, nitrates, PFAS, chlorine, and dissolved solids. Many homeowners choose RO for its exceptional purity.
While reverse osmosis is one of the most effective ways to purify drinking water, there are a few factors homeowners should be aware of. Because the process is so thorough, RO systems remove beneficial minerals along with contaminants, which can affect taste and hydration. Some people also notice the water tastes slightly “flat” without those minerals present, and traditional systems do produce a small amount of wastewater during filtration. Today’s modern RO systems that incorporate remineralization are built to address these issues.
Pure RO water contains very few minerals, which help your body absorb water efficiently. Without minerals like calcium and magnesium, hydration may feel incomplete, leading to you feeling thirsty. That’s why we recommend remineralized RO systems for optimal hydration.
To create water that’s both clean and biologically compatible with your body, RO water can be remineralized by:
For drinking water, reverse osmosis with remineralization is widely considered the gold standard. For whole-home use, pairing RO with carbon filtration and water softening (if needed) provides a complete water-quality solution for your home.
There is no scientific evidence showing that RO water harms kidney function. In fact, removing contaminants like heavy metals can reduce stress on the body. Remineralized RO water offers added balance for long-term use.
Most experts agree that the healthiest option is reverse osmosis water with added minerals. It combines maximum contaminant removal, improved taste, and proper mineral balance for hydration.
RO removes most contaminants, but it does not remove:
By testing your water and designing a system specifically for your home, professionals can recommend the most effective filtration solution—whether that’s reverse osmosis, carbon filtration, or a whole-home system—so you get clean, balanced water without guesswork.
What is the healthiest type of filter water (carbon, RO, or Brita)?
Homeowners often upgrade to a whole-home or under-sink water filtration system from pitcher filters because:
The most reliable way to confirm hard water is through professional water testing, which can identify mineral levels and determine whether a water softener is the right solution.
If you’re noticing any of these issues, hard water may be the cause:
A water softener removes calcium and magnesium—the minerals that cause hard water—from your water supply. This helps prevent scale buildup, improves soap performance, and protects plumbing and appliances from wear. While it doesn’t filter contaminants, a water softener plays an important role in improving overall water quality and system efficiency.
Yes. Water softeners reduce hard water minerals like calcium and magnesium that cause scale buildup on faucets, showerheads, and inside appliances. By preventing this buildup, a softener helps fixtures stay cleaner, improves appliance efficiency, and extends the life of plumbing and household systems, making it especially beneficial for homes with hard water.
Absolutely. At Donovan Air, Electric & Plumbing, we rely on detailed water testing to guide every recommendation. By analyzing your water’s mineral content, contaminants, and overall quality, we can determine whether filtration, softening, or reverse osmosis is the right fit.
