## Description

HydroLogicStealth-RO150/300 RO Membrane

## Features

- Stealth-ro150/300 RO membrane reduces 89%+ of ppm of total dissolved solids.
- There are two indications as to when to change your membranes.
- 1. Test the ro and source/inlet water to see what percentage of the inlet water’s ppm the 150 is filtering out (rejection %). You should see approximately 98% of the inlet ppm’s being removed when the membrane is New. If the rejection % falls under an acceptable level (typically 90%) it's time to change the membrane.
- 2. When the flow rate of the product water slows down significantly. This can also happen if your pre-filters are clogged. If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nothing like the name brand
*by G***X on October 24, 2021*

I replaced my membrane with an off-brand unit that had good reviews, good numbers and was supposed to be a direct replacement. We’ll, that wasn’t the case, lol. Tap is approximately 350 ppm. With factory membrane, before replacement I was getting around 25 ppm. Off brand was 180 ppm and also much less output even though they are both rated at 150 gpd. Now I bought this new membrane and also new sediment and carbon filters, flushed system, and I’m steadily getting less than 10ppm. I won’t buy another off brand filter or membrane again.

### ⭐⭐⭐⭐⭐ OEM or nothing. Don’t be cheap!
*by C***O on June 11, 2020*

Great flow, and 0 ppm! Don’t buy the knock offs!

### ⭐⭐⭐⭐⭐ You get what you pay for
