  1. Activated carbon filter reduces pesticides, herbicides, and other organic chemicals from the water.
  2. Catalytic carbon filtration helps in the removal of chloramines and chlorine up to 97%. These are responsible for unpleasant taste and odor in the drinking water.
  3. The ion exchange technology ensures the removal of heavy metals like mercury and lead.
  4. Finally, the sub-micron filter captures and removes cysts. 

Design:

The unit features a durable build that is complemented by a user-friendly design. You can attach it straightaway to the faucet and easily replace the filters whenever required.

NSF certified:

Being a countertop water filter, the installation does not require a significant amount of time and effort. Still, here is a step-by-step guide to help complete the task for those who are confused.

  1. First, twist off the aerator from the faucet.
  2. Attach the diverter valve after checking that the rubber washer is in place. 
  3. Now, screw the brass adapter using the plastic hex wrench tool, which comes in the package.
  4. Look for two holes at the bottom of the unit and insert the hoses into them.
  5.  Make sure the blue and white tips are inserted in their respective caps.
  6. Now, open the faucet and make sure there is no leak. 
  7. Pull over the diverter pin and allow the unit to flush for at least 10 minutes. 

Maintenance and Care

Maintenance is extremely important to make the most of the water filter and ensure it serves you for a long time. Since the capacity of the filter is 450 gallons, you must replace it once it reaches its limit. While it depends on the gallons you filter in a day, it is recommended to replace the filters every six months. 

You don’t need to call for a professional plumber to replace the filter. Just turn the filter cap, remove the cartridge, and fix the new one.
