Info: Various Filters (Please Read Carefully)
These are various individual replacement filters for use with the OPUS point-of-use / drinking water purification systems, which use 10-inch long filters.
Complete Annual Replacement Kits are also available for most of these systems, as well.
Our OPUS Whole House Systems use different filters, which are 20-inches long; those are available through the Replacement Whole House Water Filters Collection page.
Please read detailed information below; you can select the filter you need for your system from the dropdown menu.
Unfortunately, due to their size and weight, OPUS water filters and water systems no longer qualify for free shipping; our Shipping Department will follow-up with a quote before proceeding with the order.
Product Notes:
Please note, the 5 micron sediment filters come in two types: pleated or inline. The former have flat bottoms with the same circumference as the rest of the cylinder, while inline ones taper down and have tips on the ends, such as the 1 micron one pictured above; please be sure to verify which one your filter uses before purchasing replacements. (Please see the Annual Water Filter Replacement Kits page to see which stages your system has.) The 5 Micron Inline filters with store code 23788 is for chlorinated water.
Nearly all the OPUS point-of-use systems use a KDF/GAC filter, and nearly all use the .5 micron carbon block MTBE/VOC filter (except where this has been replaced with a 1 micron catalytic carbon filter).
Bone char filters are for those OPUS systems which filter out fluoride.
The 1 micron Catalytic / Activated Carbon Block Filters (PLU 10616) filter out the chloramines which are added to the water supplies in some municipalities, and also remove Chlorine, Tastes, and Odors; they are used the OPUS systems with Chloramine Redox in their name, as well as in the 1 chamber OPUS - Digital Water Filter System.
For those with an OPUS Digital Water Filter System whose municipalities treat their water with chlorine, please select the 1 Micron Pleated High Capacity CTO Carbon Filter (PLU 22491, shown immediately below) for Chlorine Taste and Odor Reduction and to remove sediments. Their Maximum Operating Temperature is 125°F (52°C).
The Bioceramic alkaline filters (pictured immediately below) add minerals and alkalinity, and are required for the AlkaPlus or AlkaNano models. This item is described in more detail here on its own page: the Anti-Oxidant Alkaline Hydrogen Reducing Filter.
The 0.5 Micron Flow Restricted Carbon Block (19742); 1 micron Pleated Sediment Filter (now 22491, formerly 21387) and the 30 micron sediment filter (18848) are for use with the CottagePure system.
Similarly, if your system once used a 1 micron Pleated Sediment Filter with the store code 21387, please get the different type we have switched such systems to 22491 (he grey/brown one pictured above).
The .01 Micron NanoFiltration Membrane Filters are for the OPUS systems with "Nano" in their names like the one pictured here, or where you have added that as an option to a pre-existing model.
The SW Water Softening Filter is for the WelLicious Drinking Water System, which is designed for drilled wells supplying hard water or those whose city water has a lot of mineral content or may be prone to discolored (brown) water.
