EQ-300 Replacement System Options

When is it time to replace my EQ-300 system?  The EQ-300 (consisting of two (2) blue tanks vertically stacked in an hour-glass configuration) was designed to last approx. 3–5 years or 300,000 gallons. As the EQ-300 expires, its overall performance rapidly declines since the media becomes saturated with contaminants. As the carbon filtration media within the system gets saturated it will start to break down and leach accumulated contaminants back into your water. Therefore, it is important to quickly replace your EQ-300 as it expires.

What systems are available to replace my expired EQ-300?  You can replace your EQ-300 with any of the PureMaster V-300, V-500 or V-700 Replacement Systems shown below. The best value is the V-700 which provides you with over twice the lifespan of the V-300 at a relatively small price difference. Each of the PureMaster Replacement Systems are ready-to-install and include the PureMaster blue tank unit with pre-loaded media and the inlet and outlet head.
