MR Replacement Under-Sink Water Filters LP-4040 Editorial Review
The Mywater 4040 RO system is a high-quality water filtration system. The system includes a carbon filter, a softening system, and a 5-micron filter prior to the RO membrane. The RO membrane is made of premium quality Toray sheets and Dow glue. While the company cannot guarantee if it will work better or last longer than other systems in all scenarios, they assure that the membrane is individually tested and made of high-quality materials. The system produces clean water, but its performance depends on incoming pressure, TDS, water quality, and temperature. Unfortunately, the system does not have a time monitoring feature to indicate when the membrane needs replacement, which may be a drawback. However, the dimensions are reasonable and two units can be shipped in one box.
