NEW: The recommended time to change filters is 60 gallons – or about every 2 months with daily use.

OLD: The lifespan of the Puritii filter varies depending on how much it is used. On average, our long-lasting filters remain effective for up to 3 months of daily use, or approximately 300 bottles of water, or 50 gallons of water.

How much water does each Puritii bottle hold with the filter in place?

NEW: Available in 16-ounce stainless steel or 25-ounce, ecofriendly Tritan™ plastic, free of BPAs, BPSs or any other bisphenols, and EA-free. Puritii water bottles are leak proof, dishwasher safe and perfect for home, office and on-the-go!

OLD: The stainless steel bottle holds 16 ounces with the filter in, whereas the plastic bottle holds 20 ounces with the filter in place.

Isn’t tap water safe to drink?

Tap water can be contaminated with a variety of pollutants that your municipal water program may not be testing for. These contaminants are called “emerging contaminants”. For example, did you know that your neighbor’s prescriptions could be coming out of your kitchen tap? Many drugs, such as antibiotics and birth control medications pass virtually unchanged through the human body and end up back in our water supplies. Researchers routinely find dozens of pharmaceuticals in tap water samples, and even in our rivers and lakes, including painkillers, antidepressants, 12 and even worse drugs, like methamphetamines and cocaine.

While most people think drinking water from the tap is safe, they don’t realize that bacteria and viruses can be swimming in your drinking glass, and traces of toxic metals and industrial contaminants are found in nearly every city water system.


It is hard for me to suck water through my water bottle, is this normal?

NEW: The good news is it is easy now! Because of how the pleat pack is designed – it allows for three times the flow rate than the old one.

What can I filter through my Puritii water filter?

Puritii is specifically designed to filter unwanted substances from fresh water sources. It is not meant to filter other liquids, such as coffee, soda, tea, salt water, juice, etc.

What does the Puritii water filter remove?

The supplied filters were submerged into a reservoir of General Test Water Type 1 (GTW1, NSF P231). The test water was drawn up through the filter at 3.50 inHg. Each filter was conditioned by the passage of 10 liters of GTW1 prior to being subjected to the filtration challenge study. The indicated challenge species were added to GTW1 (pH 7.5) and homogenized. Each filter was submerged in the challenge water and passed through each filter at an approximate flow rate of 833-909 mL/min at 3.50 inHg. Following the passage of 1 liter of challenge water through the filter, duplicate samples of the effluent were collected in sterile containers.

Testing performed using standard NSF/ANSI test methodology.
