Info: 5 micron or 20 micron Filters Available
These 20-inch long replacement filters are for use with either of the two regular OPUS Whole House point-of-entry water filtration systems, Model 55, or Model 85. Replacement intervals will vary depending on household water use and sediment levels; a filter can last up to six months.
The replacement sediment and iron reduction filters for the Whole House Iron Redox Water Filtration System are available on a separate page.
Be sure to specify in the drop-down menu whether the replacement filters you require are 5 micron or 20 micron filters; both are used in the Model 55 and Model 85 Whole House Systems, and should be replaced at regular intervals.
These filters should be replaced when the water pressure / flow has noticeably dropped; replace the 20 micron filter first (be sure to flush the filter before attaching it to the rest of the system) and, if the water pressure continues to be low, replace the 5 micron filter (which will also require preparatory flushing), next.
These filters are very large and irregular in shape, so for these products, free shipping is not included. Once we have your address, our Shipping Department will contact you to quote shipping cost; we will not proceed without your approval.
A discount of 10% per unit will be applied if you buy 6 more of either type.
