Product review (2 stars): Will not fit ReliOn Model RCM-832N Humidifier
Do not buy this product if you have a ReliOn Model RCM-832N Humidifier. The original filter RWF813 measures 3 3/4 x 5 3/4 x 1 1/2 and any replacement filter that is larger or smaller will not fit or work properly. This filter measured 3 1/4 x 6 x 1 and had to be returned.
