NEW! UltraEase™ Reverse Osmosis Filtration System Features

Three Stages of Filtration

You will notice the sound of water draining and running after each time you use the WHAROS5 Reverse Osmosis Filtration System. This is completely normal — the system is filtering and refilling clean water to your tank. Part of that process also includes rinsing out the membrane which is used to filter your water. Rest assured that these sounds are a sign of a fully functional reverse osmosis system.

Compact Design

Convenient cabinet design eliminates need to mount system allowing for easier installation and filter replacement

Faucet Included

Designer chrome faucet included.

UltraEase™ Filter Replacement

Change filter in seconds with just a quarter turn – no hassles, no mess, no need to turn off your water supply.  This system uses replacement filters WHEERF and replacement membrane WHEERM. One set of filters and one Reverse Osmosis membrane included.

6 Month Filter Life

A 6-month filter life means you only have to replace filters twice a year. It is essential to change your filters every 6 months to ensure your system is working properly. This system uses replacement filters WHEERF and replacement membrane WHEERM. Replace membrane every 2-3 years.
