The Best Home Espresso Machines For Sale Right Now

The Mahaton bottle can last up to three weeks on a full charge, assuming you run the purification cycle up to four times per day. That's slightly less than the CrazyCap and the Larq, but not such a short battery life that you'll feel burdened with charging the bottle.
While many sources of tap water and groundwater are perfectly safe, it's never worth the risk to drink water you aren't certain about. Even if it looks clean, it could be contaminated with bacteria, viruses, protozoa or other microorganisms invisible to the human eye. And despite the Safe Drinking Water Act, tap water can still contain contaminants such as arsenic, lead, chlorine, pesticides and even particles from malfunctioning wastewater treatment.
Some gadgets even create cold brew in a fraction of the time it usually takes. The $109 Gourmia Cold Brew and $129 Dash Rapid are excellent examples. Both countertop machines complete the process in minutes, not hours.

Brita Premium Filtering Water Bottle
Paige Thies/CNET Brita is known for its faucet and pitcher filters, but the company also makes plastic and stainless steel filtered water bottles. According to Brita's website, these bottles aren't intended for outside use -- they're intended for just tap water, like the Astrea bottle -- but this bottle also filtered natural fresh water just fine. The Brita bottle uses an activated carbon filter, which is extremely porous and pulls contaminants, such as chlorine and particulates.
$40 at Lifestraw Waterwell Ultrafiltration Travel Water Bottle
Produced a sour taste
Paige Thies/CNET Waterwell claims its double-stage filtration system removes 99.9% of waterborne pathogens, but based on the taste of the water that came from this bottle, I wouldn't be so sure. I didn't feel or see any particles like I did with the Lifestraw Go, but the taste alone was enough to make me wary of bringing this bottle into the backcountry.
Despite its poor filter attachment and sour taste, the Waterwell does have some good properties. It's easy to use, with the same setup as most of the other bottles on the list: bottle, cap, filter. The filter detaches easily and the bottle opening is large enough to insert a standard dish scrubber.
The CrazyCap also has an autoclean function, which turns on six times per day for 20 seconds. CrazyCap says this periodical exposure to UV-C light prevents microbial growth and odor, and it seems to work: After three days of use, I didn't notice any smells or films inside the bottle. Additionally, water from the CrazyCap bottle tasted significantly better than water from the tap faucet.
Filtering: What filtering mechanism was used and how well did the bottle filter the water? Were there any particles left in the water after filtering? Water "after filtering" means the water that comes out of the drinking spout or straw.
Paige Thies/CNET How I tested these filtered water bottles
For the sake of safe drinking water, two friends and I ventured out to a freshwater source in Southern California. We were lucky to find a tiny trickle of a waterfall in the Rancho Sierra Vista/Satwiwa Wilderness area in the Santa Monica Mountains, which culminated in a series of four tiny pools of water. Of the four water holes, we settled on testing the bottles in the one that looked the least stagnant (and had the fewest bugs and tadpoles).
AeroPress coffee and espresso maker
Amazon There are still other methods for brewing coffee -- and one of these is done via the wonderful AeroPress. Using these circular coffee filters, the AeroPress is small and lightweight, making it perfect for packing in your carry-on. It's kind of like the next step after the French press, creating a smoother cup of coffee by way of pushing the coffee through a paper filter. And, cleanup is even easier -- you're left with a puck-shaped cake of coffee grounds that you simply push into the trash (or into your compost bin) and then a quick rinse of the AeroPress sets you up for the next cup.
Because this bottle has so many parts, it's pretty difficult to clean. There's no way to get your hand or a brush inside the bottle, and the foam interior makes me worry that the inside can never get completely clean and dry. However, the website does say that it's not necessary to completely dry the Sawyer Select bottle, as the foam is also designed to prevent mold and bacteria growth.
The Sawyer Select bottle is made of BPA-free silicone, and the interior is foam. The various caps, as well as the external micron filter, are made of BPA-free plastic. The micron filter itself is a hollow fiber membrane. The bottle is squishy, but it still feels relatively sturdy.
Bialetti Moka stovetop coffee maker
Amazon Turn up the whimsy with this Bialetti stovetop espresso maker, preferably in a bright color. There is something very satisfying about watching coffee bubble up the spout and into the pour section of one of these portable espresso makers (also called a Moka Pot). As pretty as they are functional, these items are great to leave out as conversation pieces. Make coffee while camping by placing this coffee maker over your portable burner.
