Quality Drinking Water & Bottle-less Coolers

Bottled water equivalent: 15,146 x 500 ml. (16.9 oz.) bottles

The Quantum 1000 and 4000 water filters provides absolute ½ micron (1/50,000 inch) filtration, removing 99.9% of all particles like dirt, lead, asbestos fibres, harmful cysts such as Giardia lamblia and Cryptosporidium.

They also remove chlorine, and other offensive tastes and odors.

The Q4000 has more than double the capacity of the Q1000 and both water filters are interchangeable. You require the QH3 head to use either of these filters.

The Q1000 and Q4000 are third party tested and certified by the National Sanitation Foundation (NSF). This means that the claims that Everpure makes regarding performance and capacity have been tested and certified to be true.  This provides you with peace of mind that what you are buying will deliver on its promise of quality.

The two important standards are #42 and #53:

We recommend changing this filter on an annual basis or when the flow rate becomes inconveniently slow. Our water quality is changing all the time.  Even if you have your water tested, that is just a snapshot on that particular day, so don't be surprised if the frequency of cartridge change fluctuates from one year to the next; this is normal.  

What matters most is knowing that regardless of the water quality going into the water filter, the quality coming out will always be the same.  This is the promise that Everpure delivers on and that is why it is so important to only buy a water filter that is third party tested and certified by NSF. Without NSF, the manufacturer can make whatever claims they want.  Read more on this important certification.

Note: The Q1000 and Q4000 water filters fit exclusively in the QH3 head only
