TL;DR: Water filtration systems often get misunderstood. Common water filtration myths, like “filtered water tastes bad” or “all filters are the same,” can prevent you from making the best choices for your water quality. Learn the truth about filtration’s effectiveness and how the right system provides clean, safe, and great-tasting water.


Water filtration systems play a vital role in keeping your water clean and safe, but misinformation can lead to confusion or hesitation about using them. Debunking these misconceptions about water filters in NH will help you understand how effective and valuable filtration systems really are.

Myth 1: Filtered Water Tastes Bad

One of the most persistent myths is that filtered water has a strange or unpleasant taste. In reality, a properly functioning filter improves taste by removing contaminants like chlorine, sediment, and metals.

If filtered water tastes bad, it’s likely due to a poorly maintained system or an expired filter. Replacing the filter regularly restores the fresh, clean taste you expect.

Myth 2: All Filters Are the Same

Not all filters are created equal, and this myth can lead to poor decisions when choosing a system. Some filters target specific contaminants, like lead or PFAS, while others provide general filtration.

A carbon filter, for example, removes chlorine and improves taste, while a reverse osmosis system addresses heavy metals and nitrates. To maximize filter effectiveness in NH, select a system that matches your specific water quality needs.

Myth 3: Water Filtration Is Only Necessary for Well Water

City water is treated before it reaches your tap, but that doesn’t mean it’s free from contaminants. Municipal water systems often leave trace amounts of chlorine, lead from old pipes, or even PFAS in your water. Sometimes, a public water filtration system is necessary. Whether you use city water or a private well, it’s important to test your water for potential contaminants.

Myth 4: Water Filtration Systems Are Expensive

While the upfront cost of a water filtration system might seem high, it saves money in the long run. Bottled water costs significantly more over time, and poor water quality can damage appliances, leading to expensive repairs. Filtration protects your plumbing and appliances while providing a steady supply of clean, affordable water.

Myth 5: Maintenance Is Too Complicated

Some people avoid filtration systems because they think upkeep is overwhelming. In truth, maintenance is straightforward for most systems. Replacing filters according to instructions and scheduling annual professional inspections are often all that’s required.

Proper maintenance ensures filter effectiveness in NH and extends the lifespan of your system. The cost of not maintaining your filtration system is typically higher in the long run.

Myth 6: Water Filtration Is Only About Drinking Water

Many assume water filters are only for drinking water, but they improve water quality throughout your home. A whole-home system reduces scale buildup, protects appliances, and ensures better water for bathing and cooking. The benefits go far beyond what’s in your glass.

Why Understanding the Facts Matters

Believing these water filtration myths can lead to poor water quality and missed opportunities to improve your home’s health and efficiency. The truth is, modern filtration systems are effective, affordable, and adaptable to your specific needs. By choosing the right system and maintaining it properly, you’ll enjoy clean, safe, and great-tasting water without compromise.
