ASKED QUESTIONS

How do I condition my Purefast filter before use?

It is important to follow the 4-step filter preparation instructions included in the Purefast User Guide. This easy 5-minute conditioning process will ensure smooth filtration and fresh tasting PFAS-free water:

Step 1. Run small streams of tap water through the top of the filter for 15 seconds. Turn the filter upside down and allow water to flow through each bottom screen for 15 seconds – a total of 60 seconds.

Step 2. Fill your pitcher with water and hold the filter under water. Gently shake and tap the filter against the interior wall of the pitcher to fully wet the media for about 2 to 3 minutes, or until you no longer see air bubbles coming out of the filter.

Step 3. Insert the filter into the pitcher reservoir by lining up the groove in the filter with the notch in the reservoir (if applicable). Gently press the filter down to secure the filter in the reservoir.

Step 4. Before use, fill the reservoir with tap water and discard the filtered water. For best results, avoid pouring tap water directly on top of the filter. Repeat this step two to three times.

For the best hydraulic performance, it is recommended to recondition the filter every 30 days. Larger households and those using the Ultramax pitcher model may need to recondition the filter every 2 weeks. To recondition, remove the filter and shake gently before following conditioning steps 1-3 (above).

How effective are Purefast filters in removing PFAS compounds?

Cyclopure internal testing demonstrates reduction of 11 PFAS (PFOA, PFOS, PFHxA, PFHxS, PFNA, PFDA, PFHpA, PFPeA, PFBS, PFBA, HFPO-DA (GenX)) to non-detect for 65 Gallons capacity based on influent concentration of 40 ppt per PFAS.

How do I recycle my Purefast filter?

Sustainability is one of our top priorities. Purefast will do the work to achieve ZERO PFAS in your drinking water. If you return your used filter to us, we will ensure that ZERO PFAS waste goes to the environment.

Each Purefast filter comes with a pre-paid mailer to return used cartridges to our lab for safe disposal. When you open the package, check the mailer and store it where you will remember, such as a catchall drawer in the kitchen.

When the filter is fully used, place the spent cartridge in the mailer, seal it, and drop off the package at the post office to return. Postage is already paid!

Is it okay if there is moisture in the Purefast packaging?

Each Purefast filter comes pre-conditioned for smooth filtration. You may find some moisture or a small amount of water when you open the packaging. This is normal.

How should I store my filter if I plan to go out of town?

For short term storage (1-2 days), we recommend leaving the filter in the pitcher (with filtered water) and storing the pitcher in the refrigerator.

For long term storage (3+ days), we recommend leaving the filter in the pitcher (no water in the pitcher) and storing the pitcher in the refrigerator.

Before the next use, you may need to recondition the Purefast filter by following the steps in Q1.
