990120 - L100 ERV REPLACEMENT CORE FOR RENEWAIRE EV PREMIUM L, EV PREMIUM X, EV90P, EV200, EV240 AND EV300 - This is a factory original replacement G5 core. This is the latest generation (G5) core. The core of the Renewaire unit comes with a factory 10-year warranty. If the core has been properly maintained, it will not need to be replaced. The only times when it should be replaced is if it has mechanical damage or if it got wet and there is mold or mildew on it. Under normal operation of the unit, neither of these situations should occur, so in most cases the core doesn't need to be replaced. It is normal for the core to be stained under normal use. This is because some dust will accumulate on the incoming side of the core. If this happens, use a soft bristle brush tip on a vacuum cleaner and vacuum it carefully. You want to make sure that the air can go through the core. If the air is not being blocked, the unit will operate normally. It is also good practice to replace the filters regularly. As a rule of thumb, they should be replaced every 3 months. This will help keep the unit working very efficiently. The new core will slide into the existing unit. It comes with a 10-year Manufacturers Warranty.
