Buying Guide for the Best Reverse Osmosis Systems

Choosing the right reverse osmosis (RO) system for your home or business can be a bit overwhelming, but understanding the key specifications can help you make an informed decision. Reverse osmosis systems are designed to purify water by removing contaminants, making it safe and clean for drinking and other uses. Here are the key specifications you should consider when selecting an RO system, along with explanations to help you navigate through them.

Filtration StagesFiltration stages refer to the number of steps the water goes through to be purified. Each stage typically removes different types of contaminants. More stages generally mean better filtration. Systems can range from 3 to 7 stages. For basic needs, a 3-4 stage system might suffice, but for higher purity, especially if your water has specific contaminants, a 5-7 stage system is recommended.

Water Output (GPD - Gallons Per Day)Water output indicates how much purified water the system can produce in a day, measured in gallons per day (GPD). This is important to ensure the system can meet your daily water consumption needs. For small households, a system with 50-75 GPD might be adequate. Larger households or small businesses might need systems with 100 GPD or more.

Storage Tank CapacityThe storage tank capacity tells you how much purified water the system can store at a time. This is crucial for ensuring you have enough water available when you need it. Smaller tanks (2-3 gallons) are suitable for small families, while larger tanks (4-10 gallons) are better for bigger families or higher usage scenarios.

Filter Replacement FrequencyFilter replacement frequency indicates how often you need to change the filters to maintain the system's efficiency. This can vary based on the quality of your water and the system's design. Typically, filters need to be replaced every 6-12 months. Consider your willingness to perform maintenance and the cost of replacement filters when choosing a system.

Contaminant Removal RateThe contaminant removal rate shows the percentage of contaminants the system can remove from the water. Higher rates mean cleaner water. Most RO systems remove 90-99% of contaminants. If you have specific concerns, such as high levels of lead or chlorine, look for systems that excel in removing those particular contaminants.

System Size and InstallationSystem size and installation refer to the physical dimensions of the RO system and how it is installed. This is important to ensure it fits in the designated space, usually under the sink. Some systems are more compact and easier to install, while others might require professional installation. Consider your available space and whether you prefer a DIY installation or professional help.

Waste Water RatioThe waste water ratio indicates how much water is wasted for every gallon of purified water produced. Lower ratios are more efficient and environmentally friendly. Common ratios range from 1:1 to 1:4. If water conservation is important to you, look for systems with a lower waste water ratio.
