Customer Reviews for Premier 24-gallon-Per-Day Replacement Membrane for Reverse Osmosis Systems
Review 1 for Premier 24-gallon-Per-Day Replacement Membrane for Reverse Osmosis Systems
Pros: works beautifully without any problems., best price available
"We have bought the Premier reverse Osmosis System, and Premier replacement membranes and filters from Costco for years. Each time we move, we buy another. The System works excellently, and the filters really do their job. Our city water is so bad no one drinks it; it is high in mineral content and chlorinated. When we change filters, the old ones are stained the color of our red earth. This system, and the filters and membranes work so well that our water has no taste whatsoever. That is our goal, and it is met absolutely by Premier Filtration Systems.
I would like to add that Costco offers these products at the best price available anywhere, online or bricks-and-mortar stores. Thanks to Costco for providing a top quality system, and its components, at such a reasonable price."
