How to Choose the Right RO System
-
Match Capacity to Usage
Start by determining your daily water needs. If you are in a home with low pressure, the 50 GPD model with a booster pump provides a practical solution for drinking water. For larger households or light commercial settings like cafes, consider systems with 200 GPD or higher output. The 400 GPD and 600 GPD options offer steady flow for busy environments. Ensure the gallon per day rating aligns with your peak usage times to avoid running out of purified water during busy periods.
-
Check Booster Pump Needs
Most Premier Water Systems require a booster pump to function correctly. This feature is essential if your inlet water pressure is below the required threshold. The 50 GPD residential unit and several commercial models include this pump to ensure consistent filtration. Without adequate pressure, the reverse osmosis membrane cannot effectively remove contaminants. Verify that your installation site has the necessary electrical connections for the pump. If you already have high pressure, you might still need the pump for optimal performance and membrane longevity.
-
Select Tankless or Tanked Design
Decide between a system with a storage tank or a tankless design. The 400 GPD Light Commercial RO is a tankless option, which saves space and provides continuous flow. This design suits businesses that need high output without the footprint of a large storage tank. Most other models, including the 50 GPD and 200 GPD units, include tanks to store purified water. Tanks allow you to draw water quickly without waiting for the filtration process. Choose based on your available under-sink or commercial space and your flow rate requirements.
-
Consider Filtration Stages
Look at the number of filtration stages to understand water purity. The 50 GPD residential unit features a 5-stage process, which typically includes pre-filters, the RO membrane, and a post-filter. This setup ensures safe, filtered drinking water by removing sediment, chlorine, and dissolved solids. While not all commercial models list their exact stage count, the 5-stage configuration is standard for residential safety. More stages generally mean better contaminant removal. Check the specifications to ensure the filtration aligns with your water quality concerns and usage needs.
-
Verify Physical Dimensions
Measure your installation space before purchasing, as commercial units vary significantly in size. The 400 GPD model measures 10 by 16 by 20 inches, while the 600 GPD unit is larger at 12 by 18 by 36 inches. The 200 GPD and 300 GPD models share similar dimensions, requiring ample space for installation. Ensure your cabinet or commercial area can accommodate the unit’s width, height, and length. Tankless models may have different footprints compared to tanked systems. Accurate measurements prevent installation issues and ensure the system fits your intended location without modification.
