Undersink Filter Replacement Parts

Undersink Water Filters, Cartridges, and Parts. Single, Double and Triple Filters.

Multi-cartridge filters are much under-rated. A good undersink double or triple filter can produce very high quality drinking water for many years with maximum convenience, minimum maintenance, and at a cost that is only a fraction of that of bottled water. Undersink filters use neither electricity, like a distiller, nor water, like reverse osmosis, so they're economical performers with a basic simplicity that makes them almost maintenance-free.

Our basic Black and White series includes single, double and triple. All use top quality, heavy-duty parts. All are standard sized to make parts easy to find, and so tough you should never need parts except filter cartridge replacements. Filter cartridges are the most common size made, the basic “10-inch filter” sold everywhere.

The basic Black and White undersink units include a choice of our basic Pro-Flo or the Contemporary “Value” Tomlinson brand faucets (other styles and finishes are available on our faucet page) and an inlet valve for easy installation. Fittings are all John Guest quick connect — push the tubing into the fitting and forget it. No tools needed.

All our Black and White single, double and triple filters are mounted on brackets and can be either hung on the wall or stood in a secure undersink location.

Standard filter cartridge setup is given in the price list below, but other cartridges are available and may be substituted to meet special needs. (If you substitute cartridges, the easy way to order is by phone, or if you prefer, you can order the standard system on the shopping cart and add your cartridge substitution instructions to the Comments section of the shopping cart.)

The cartridges, which form the heart of these systems, are rugged, effective top performing carbon blocks. Specialty cartridges, top quality “media” filters, are also offered. These can be used to reduce problem contaminants like nitrates, sodium, and fluoride, although cartridges in this category usually have limitations. (If sodium removal is a major concern, as an example, you would do better to look at a reverse osmosis unit, because specialty sodium cartridges have a short lifespan and can be expensive to replace. Reverse osmosis removes fluoride, sodium, and nitrates by its nature without added specialty filters.)
