Review: 5 stars for value - 5 stars for value - removes an average of 95% of impurities from tap water. I’ve bought a few of these, and that’s about the average. You’ll need to spend more if you want more removal - like $160+. I run this RO on my Waterfed window cleaning system without issue. Will last me 150+ jobs before I see a drop in performance.
Review: Decepcionado - Buy this product in June 2024 and I must change it, it started to pass high calcium content and the fatal water quality of 255 at the entrance I have at exit 155. I don't understand if I've changed the Prefilter every month x that has lasted either time Compre este producto en junio 2024 y ya debo cambiarlo, empezó a pasar alto contenido de calcio y la calidad del agua fatal de 255 a la entrada tengo a la salida 155. No entiendo si he cambiado el Prefiltro cada mes x que ha durado tampoco tiempo

### ⭐⭐⭐⭐⭐ Good membrane.
*by J***Y on May 20, 2024*

This is a nice 4040 sized commercial reverse osmosis membrane. These are good for removing the majority of dissolved solids, sediment, and bacteria/viruses from water at up to 2600 gallons per day. This particular membrane is also meant for desalinization, making it appropriate for making ocean water potable. The membrane appears to be well made and I have confirmed that it fits in a standard 40 inch membrane housing. For the quality and the price I find it to be a very good value.
