How long does the filter cartridge last?

Can I use the UltraPress with saltwater?

No, the UltraPress is not designed for use with saltwater.

How do I clean the UltraPress?

Rinse all parts with clean water after each use. Use a damp cloth to clean the exterior. Do not use soap or harsh chemicals.

How do I know when to replace the cartridge?

Replace the cartridge when the press time reaches approximately 25 seconds, or three years have elapsed since first use.

What contaminants does the UltraPress remove?

The UltraPress removes waterborne pathogens (viruses, bacteria, protozoa), particulates, microplastics, chemicals, pesticides, herbicides, heavy metals, VOCs, flavors, and odors.

What materials is the UltraPress made of?

The UltraPress is made from BPA-FREE polypropylene #5, food-grade silicone, TPE, and ABS food-grade plastic.

Can the UltraPress withstand freezing temperatures?

While the UltraPress itself may not be damaged by freezing, it is generally recommended to avoid freezing the water inside as this could damage the filter cartridge or affect the bottle's integrity over time.

Troubleshooting

Water flow is slow.

Ensure the cap is properly vented. If the issue persists, the cartridge may need to be replaced. Also, check for any blockage in the spout.

The bottle is leaking.

Check the seals and the cap for proper alignment. Tighten the cap and ensure all parts are correctly assembled.

The press is difficult.

Ensure the cap is properly vented. Apply even pressure when pressing. The SoftPress pad is for comfort and the FlipCarry handle provides leverage.

Water tastes off.

Rinse the bottle and try another source of water. If the taste persists, the cartridge may need replacing.
