Our premium water filters for the home are the MB Series filters.  If you are on Seattle water (or similar quality) with more than four people in your home, this is the water filter for you.  The MB818 will filter your tap water to produce purified water, similar in quality to distilled or reverse osmosis water. Use the water with confidence, knowing that 98% of all contaminants are removed including fluoride and lead, as well as chlorine, organic chemicals, sediment, and parasites like cryptosporidium and giardia.  You can save on your home power and water bills because these filters don’t require electricity, or produce any waste water – unlike distillers and reverse osmosis.   The highly purified water is produced at a rate of one gallon per minute, so you will never run out of purified water. The primary treatment method used is deionization by ion exchangeActivated carbon is also used as a pre filter and post filter.

The filter comes with the standard, polished chrome dedicated faucet that won’t leach lead into the water.   You can also choose to upgrade your faucet from our selection of lead free 
designer faucets.  When ordering this filter, select the desired faucet style and finish.  If an upgrade faucet has been selected, the purchase price will adjust accordingly.  If you desire a faucet finish other than polished chrome or satin (brushed) nickel, please contact us by phone or email to place a special order.

 You can monitor the quality of the water coming from this filter right in your home, with just the touch of a button.  When the light shows green, you have great tasting, purified water.  When it shows red, it will be time to service your filter.

The filter comes with installation instructions for you to install yourself and you may preview the installation instructions by looking at the owner’s manual.  This water filter is designed to provide some flexibility to accommodate tight installation spaces.  You can place the resin tank at the rear of a sink base cabinet and put the cartridge housings on either side of the cabinet.  The two sections are connected by polyethylene tubing.  The ease of installation is entirely dependent on the details of your installation site and your skill set and comfort level with plumbing work.  We are happy to install it for customers in the Seattle area, for an additional charge.   Please call us to make an appointment.

Estimated Capacity:  Choosing the proper size filter is vitally important.  We recommend getting a filter that  has the capacity to meet your needs for a full year before it needs servicing (replacement of filtration media). On low mineral content water supplies (similar to Seattle tap water),this particular filter can have a capacity of approximately 1800 gallons.  This is the typical annual amount used for cooking and drinking water in a 5-6 person household.   This is the largest practical size to fit under a kitchen sink and  is commonly used on water supplies with elevated mineral content.  When used on a water supply with an elevated mineral content, the filter should be monitored on a regular basis to determine when servicing is needed.  It can be monitored with a TDS tester.

We want to be sure you receive a filter that will have a reasonable capacity on your water supply. If you  are outside the Seattle area and have not yet  contacted us about the proper size filter for you , please use our Residential Water  Consultation  to get the dialog started.  We will not ship an MB Series filter outside the Seattle area unless we already have information about your source water and the number of users in the household.
