Water Filtration Myths: What Every Homeowner Should Know

Water quality is a hot topic in the Denver metro area—and it’s also an area full of half-truths. Let’s clear up a few common myths so you can make confident, informed decisions for your home.

Myth #1: Bottled water is always cleaner than tap water

Bottled water can be convenient, but “cleaner” isn’t guaranteed. Some bottled water is simply treated municipal water, and quality can vary by brand and source. Bottles can also sit in heat during shipping or storage, which isn’t ideal. The better question is: what’s in your water right now—and what do you want to improve (taste, odor, chlorine, hardness, specific contaminants)?

A properly selected home filtration system can give you consistent, on-demand water quality from every tap—without the ongoing cost and waste of single-use bottles.

Myth #2: A water softener filters out contaminants

Water softeners are designed to reduce hardness minerals (typically calcium and magnesium). That helps with scale buildup, dry skin, spotty dishes, and appliance wear—but it’s not the same as contaminant filtration. A softener doesn’t automatically remove things like chlorine taste/odor, sediment, or other unwanted substances.

If your goal is better-tasting water and broader protection, you usually need a filtration approach that’s matched to your water conditions—not just hardness.

Myth #3: Filters remove every contaminant

No single filter removes everything. Different technologies target different issues—sediment, chlorine, taste/odor, hardness, and more. That’s why “one-size-fits-all” solutions often disappoint.

The most effective approach is to start with a water test, identify what’s present, and then choose a system designed for those specific needs. At PureWay, we focus on customized Colorado-specific solutions and components that meet NSF International and Water Quality Association (WQA) standards.

Myth #4: Municipal water doesn’t need filtration

Municipal water is treated and regulated, but that doesn’t mean it’s perfect for every home. Treatment methods can leave behind taste and odor issues (like chlorine), and water quality can change as it travels through pipes. Some homeowners also want extra peace of mind for their family—especially when they notice dryness, scale, or unpleasant taste.

Filtration isn’t about fear—it’s about improving comfort, protecting plumbing and appliances, and getting water you actually enjoy using every day.
