Tyler Lizenby/CNET Dash Rapid Cold Brew System
The $129 Dash Rapid is part of a new wave of fast cold-brew coffee makers. It uses an electric pump to create internal vacuum pressure. This pressure causes water to circulate between a glass carafe, through coffee grounds within a filter chamber and back. The machine runs the loop continuously during the brewing process. Afterwards, in as little as 5 minutes, brewed coffee returns to the Dash's carafe. As cold brew goes, what the Dash makes has a bit of a weak taste. That said, it's drinkable and fits the bill if speed is your priority. 

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. 

I'm willing to bet that you've all heard the concerns about heavy metals, chlorine and other chemicals in our drinking water -- and many of these worries are well founded. Even cities in developed countries, including the US, struggle with polluted water, posing a serious health risk to the people who live there.

Our filtered water bottle pick
Lifestraw LifeStraw is a go-to for outdoorsy folk, and rightfully so: This reusable bottle uses a two-stage filtration system that can remove nearly 100 percent of bacteria and parasites in natural bodies of water, as well as chemicals such as chlorine and pesticides.

id="cnetReview" section="rvwBody"> For $45, the Wi-Fi-equipped Brita Infinity pitcher promises to keep track of how much water is passing through the filter. Once the filter is about spent, it'll go ahead and automatically order a replacement from Amazon that'll arrive at your doorstep just when you need it.

Andrew Hoyle/CNET Since it was impossible to shoot the car safely on the bridge, I opted to shoot it from an elevated location, looking down, where it was surrounded by mountains. I zoomed in using the telephoto lens on the iPhone 11 Pro and shot in raw, giving me more scope to edit the shot afterwards. 

Bialetti Cold Brew Coffee Maker
Made to live in your fridge, the affordable Bialetti Cold Brew pitcher can pour directly into glasses. Its internal stainless steel mesh filter basket has a wide mouth that accepts the coffee grinds without making a mess, and the airtight lid keeps the taste fresh. The concentrated brew it makes is also strong, rich and packed with a pleasant coffee taste. The main drawback with this brewer is you need to drain its filter into the carafe by hand.

The most dangerous amounts of lead accumulate when the water has been sitting in your home's pipes overnight, so if you flush that immediate water out, you'll be in better shape.

I prefer the durability of stainless steel, but it's lightweight and comes with a carabiner, so it would make a good backpacking water bottle.

Lead and chlorine in drinking water
Even if your water smells and tastes fine, harmful chemicals could be lurking inside. Water pollutants fall into different categories, but the main ones of concern in your shower water are toxic metals, chlorine (used as a disinfectant) and the byproducts that chlorine creates with other chemicals in the water.

And if you'd rather not spend that much, there are plenty of cheaper, yet just as durable, alternatives. Oxo's $49 cold brewer is affordable and easy to operate, and makes excellent cold-brew coffee concentrate. Likewise, the $24 Takeya and $30 Bialetti pitchers also have prices that are easy to swallow. Traditional cold brewers like those require at least 12 hours to produce their beverages, but devotees will tell you the stuff is worth the wait.

Lead is often deemed as the biggest offender -- water slowly corrodes the lead in home plumbing systems, and the toxic metal seeps into the water. Children are at a particularly high risk and have been reported to absorb up to 50% of their lead through drinking water. Even at relatively low levels, WHO reports that lead exposure can cause irreversible neurological issues.

Brita's smart pitcher is $20 more than an identical Brita pitcher with no smarts to speak of, so the question here is whether or not that Amazon Dash integration is worth the extra 20 bucks. In theory, it's a useful bit of automation -- especially if you already buy replacement filters on the regular. In practice, it isn't all that precise, and more than anything seems designed to get people to buy new filters more often than they would out of habit alone. It certainly isn't something that anyone needs, but it might make a decent gift for a friend who's picky about filtered water.
