Buyer's Guide 2026: How to Choose the Best Home Reverse Osmosis Syste
5 Steps to Choosing the Right Reverse Osmosis System
Selecting a home RO system can feel overwhelming, but breaking it down into clear steps makes the process easier. Here’s how to get started:
1. Test Your Drinking Water
The first step is understanding the quality of your water. Professional water testing identifies the contaminants present in your water, from common issues like chlorine and iron to more serious concerns such as lead and PFAS (“forever chemicals”).
At Clean Water Ohio, we offer free in-home water testing to give you a detailed picture of your water quality and recommendations for the best filtration solution.
2. Understand Filtration Options
Not all water filters are created equal. Simple pitcher or refrigerator filters may improve taste and reduce chlorine, but they cannot remove the full range of contaminants that an RO system can handle.
Reverse osmosis systems use a high-pressure membrane to remove dissolved solids, bacteria, viruses, microplastics, and other contaminants. Advanced AO Smith RO systems combine multiple stages of filtration to ensure comprehensive water treatment, giving you clean, clear, and safe water for drinking and cooking.
3. Consider Features and Preferences
Modern RO systems come with a variety of features designed for convenience and efficiency. Key considerations include:
-
Smart technology: Some AO Smith systems include filter life monitoring, usage tracking, and alerts for maintenance, making it easier to keep your system running smoothly.
-
Faucet options: Choose a faucet style that fits your kitchen design. AO Smith offers multiple finishes and designs to match your space.
-
Tankless vs. tank: Tankless RO systems provide filtered water on demand, while tanked systems store filtered water for immediate access, depending on your household needs.
4. Evaluate Total Costs
Understanding the total cost of ownership is critical. AO Smith RO systems offer long-lasting filters and membranes, with predictable replacement schedules. This helps you budget accurately and avoid unexpected costs while reducing reliance on single-use bottled water.
5. Check System Quality
Quality is more than just filtration performance. Look for:
-
System efficiency
-
Durable, space-saving designs
-
Third-party certifications for contaminant reduction
-
Expert support and service
AO Smith’s RO systems are built for reliability, efficiency, and easy maintenance, ensuring you get the most out of your investment.
