Premier Water Systems vs Premier RO
Capacity and Output
Premier Water Systems offers a 50 GPD capacity, suitable for typical household drinking water needs. It includes a booster pump to handle low feed pressure between 30-50 psi, ensuring the tank fills efficiently. In contrast, Premier provides a massive 400 GPD output. This unit is designed for high-volume demands, featuring a booster pump that operates effectively with feed water pressure ranging from 22 to 95 psi. The difference is significant, with one system producing eight times more purified water per day than the other. You must choose based on your daily usage volume.
Design and Form Factor
The Premier Water Systems unit is a complete home system, implying a traditional setup with a storage tank, though the tank is not explicitly detailed in the specs. It is designed for under-sink residential installation. Premier, however, is explicitly a tankless, light commercial system. It features oversized 20-inch pre-RO filters and measures 18 inches long, 12 inches wide, and 36 inches high. This unit weighs 38 pounds. The Premier design is built for higher throughput without relying on a pressure tank, making it distinct from the residential model which relies on tank storage for continuous supply.
Filtration Stages
Premier Water Systems specifies a 5-stage reverse osmosis filtration process. This configuration is standard for residential units, targeting contaminants like chlorine, taste, odor, VOCs, fluoride, arsenic, and lead. The system handles feed water up to 2000 ppm TDS. Premier does not list the number of filtration stages in its published data. While it mentions oversized 20-inch filters for pre-treatment, the exact stage count for the RO membrane and post-filtration is not provided. Without this specific data, we cannot determine if the stage count matches or exceeds the five stages of the Premier Water Systems unit.
Intended Use
Premier Water Systems is marketed for home drinking water. It treats tap or well water to provide clean, crisp-tasting water for household consumption. The inclusion of a lead-free faucet and food-grade tubing supports this residential focus. Premier is labeled for light commercial use, suitable for restaurants, labs, salons, cafes, offices, and schools. Its 400 GPD capacity and tankless design cater to higher traffic and commercial requirements. If you are outfitting a business or a high-demand environment, the Premier unit is the appropriate choice. For a single household, the Premier Water Systems model is designed for that purpose.
Filter Size and Life
Premier highlights the use of oversized 20-inch pre-RO filters. These filters provide up to 30,000 gallons of filtered water, which is twice the capacity of industry-standard 10-inch filters. This suggests longer filter life and reduced replacement frequency for the Premier system. Premier Water Systems does not specify filter dimensions or gallon capacity in the provided data. It mentions premium long-lasting filters but lacks the quantitative metrics found in the Premier specs. The explicit gallon capacity of the Premier filters gives you a clear benchmark for maintenance planning that is absent for the residential model.
