UltraPress Water Purifier - Forager Moss

Product Information

The GeoPress always felt bulky. Unless you’ve got hands like Dwayne Johnson, it feels super chunky, like you’re a child stealing from your parent’s flask. It’s not physically hard or uncomfortable to hold, it just doesn’t feel right. Multi-functional SimpleVent™drink cap vents air (by twisting cap ½ turn) during purification and filtration; protects spout from cross-contamination. Durability: built tough to perform in harsh conditions and withstands 10 ft drops (full of water) onto concrete. Clean and dry the bottle between uses. Always remove the filter and clean the rest of the bottle with warm soapy water if you won’t be using it for a while. Leave the filter upside down in a warm room to dry out. It can take days for the filter to dry completely.

I’ve judged the performance of the Grayl UltraPress on how effectively it removes contaminants, and for how long. Based on these factors, the Grayl bottle offers high-quality, reliable performance.

If you have access to a dishwasher, most of the Grayl UltraPress is dishwasher safe. The filter isn’t suitable for the dishwasher, so make sure you remove it first.

If you know you’ll have frequent water sources, why not carry a lighter bottle? In our opinion, a filter bottle should never be your only water storage, as you should carry another bottle or bladder for storing purified water. Even if you don’t use the Grayl UltraPress regularly, you should still change the filter after three years, when it reaches the end of its shelf life. Using the filter after this time may prove ineffective.Filters: Particulates (sediment, microplastics) and ultra-powdered activated carbon adsorbs many chemicals (including PFAS & VOCs), pesticides, herbicides, heavy metals, flavors and odors. FlipCarry® handle rotates 90° for effortless separation (Inner Press from Outer ReFill) and easy carrying; provides a large pressing surface when flat. For context, I had the cap on, and I opened it half a turn to vent air. I was using the filter press on a surface about hip-high. It may have been faster if I had pressed down on the ground. So filter times may vary depending on your method. Ultra-powdered activated carbon adsorbs many chemicals (including PFAS & VOCs), pesticides, herbicides, heavy metals, flavors and odors.

Materials: Titanium, BPA-FREE polypropylene #5, food-grade silicone, TPE and ABS food-grade plastic. Award winning OnePress® global protection is effective on all 7 continents and empowers adventurers and travelers to drink from the world’s sketchiest freshwater sources. Simply — Fill. Press. Drink.®I found that with the Ultralight, after a while the press became very difficult to press, especially with the sort of awkward design of the lid. Grayl made an improvement here in a big way. The UltraPress cap is wider so your palms can use a flat pad to press down without the top lid digging into your hand. RiverFlow™spoutdelivers a fast-flow of clean drinking water for chugging, filling hydration reservoirs and other bottles. The FlipCarryâ„¢ handle found on the UltraPress adds a shit ton of tech to the cap. Why? The FlipCarryâ„¢ handled provides an enlarged pressing surface when flat; rotates 90° for effortless separation and easy carrying. May not sound like a big deal but it is. To reduce the frequency of filter changes, the manufacturer recommends pre-filtering dirty or cloudy water in a t-shirt before filling the bottle. This will remove sediment and dirt.

Aside from filter changes, you should clean the UltraPress after every time you use it. Cleaning involves performing a “dry press”– pressing the purifier into the empty bottle and getting rid of any excess water. Leave the filter for up to 4 days to dry thoroughly, which will prevent a buildup of odors and mildew while the filter is in storage.For the first few mornings, I simply used the outer cup as my coffee cup. The butterfly handle felt great in my hand and the cup did an awesome job of keeping my coffee warm. While that’s all well and good, I was really curious about how the filter would handle the heavy runoff water beneath our camp. (Photo/Josh Kirchner)
