  • [1โ€“3ฮผm Advanced Filtration] Powered by activated coconut shell carbon, the CB filter effectively filters particles as small as 1โ€“3ฮผm. It significantly reduces odor, bad taste and other impurities while supplying smooth, refreshing water. *Tested by a third-party laboratory
  • [1,056-Gallon High Capacity] With a lifespan of up to 1,056 gallons โ€” equivalent to roughly 8,000 standard 16.9 oz plastic water bottles โ€” this filter delivers clean, fresh water for up to 12 months under normal use. *Actual service life may vary depending on local water conditions and daily consumption
  • [3-Second Quick Replacement] Featuring a twist-and-pull design, the CB filter can be replaced in just 3 seconds โ€” no tools required. The pre-assembled, all-in-one cartridge ensures a leak-proof seal and easy installation. *After replacement, please reset the system and flush the filter for optimal performance

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
