How does the filter work?
We developed our high-performance Affinity filtration technology by combining seven different materials, each of which is known for its strong absorbent properties. Together these materials work harmoniously in a process called ionic adsorption. As water passes through the filter contaminants will ionically bind to these materials, permanently removing them to give you filtered water that is clean and safe.
How often should I change my filter?
The filter's efficiency begins to drop off significantly at 100 gallons. Because we drink water at different rates, you may reach the 100-gallon mark at different times. Here is our recommended timetable for replacing your filter:
Families: 2–3 months
Couples: 3–4 months
Individuals: 4–6 months
If you'd like to run the calculations yourself, it's pretty easy to figure out how long it will take you to filter 100 gallons of water. The top reservoir is ½ gallon when completely full. If you fill it twice each day, you'll filter 100 gallons in 100 days, or around 3 months.
Which contaminants does the pitcher filter remove? (e.g., Fluoride, Lead, Chlorine)
Our filtration technology removes over 230 contaminants. We use an independent, EPA-certified lab to rigorously test our filters to NSF standards. Here are just a few of the more notorious contaminants this filter removes:
Fluoride: removed at a rate of up to 98.2%. It is difficult to remove once it’s added into the tap water and typical carbon-block style filters don’t have fluoride removal capabilities. For that reason, we specially formulated our technology so fluoride removal is standard with every filter.
Glyphosate: The active ingredient in Roundup weed killer. Our filters remove 99.9% of this highly controversial chemical.
PFOA/PFAS/PFOS: The chemicals that make pans and apparel “non-stick” but are extremely toxic when consumed. Removed at a rate of 99.9%.
Lead: Even though it’s been widely banned due to its highly poisonous nature, lead pipes remain in use across all 50 states. Lead is harmful to human health even at low exposure levels and accumulates in the body over time. Removed at a rate of 99.5%.
Chlorine: While chlorine is effective at reducing the spread of infectious waterborne diseases, it reacts with naturally occurring materials in water to form dangerous chemical byproducts that threaten your health. Removed at a rate of 99.9%.
We are all about transparency so we post our test results on our Test Results Page. It shows the name of the particular contaminant, the concentration before filtration, the concentration after filtration, and the percentage removed.
