You picked your apartment for the neighborhood, the layout, maybe even the natural light. But there’s one thing you probably didn’t get to choose: the water.

Even if your building’s plumbing is in great shape, contaminants can enter your water long before it reaches the pipes that deliver it to your fixtures…

And if your plumbing is old? 

Age is another layer of risk that can affect every glass you drink, every pot of pasta you boil, and every bottle you fill for the gym.

The problem is, if you’re renting—or living in a condo or townhome governed by an HOA—you typically can’t make major plumbing modifications. Some leases outright forbid it. Some HOA bylaws restrict it. And even when it’s technically allowed, the hassle and cost might not make sense. 

So does that mean you’re stuck drinking whatever comes out of the tap?

Absolutely not.

Let’s dive into what’s actually in your water, why it matters more in apartments (and other multi-unit buildings) than most people realize, and portable solutions proven to protect you.

• Tap water can pick up contaminants at the source, during treatment, and through aging municipal infrastructure. Older apartments (especially those built before 1986) add another layer of risk through lead pipes, corroding fixtures, and outdated plumbing.

• Renters and condo owners typically can’t modify plumbing, but effective, portable filtration options exist that require zero plumbing changes.

• Clearly Filtered offers portable solutions—including a Filtered Water Pitcher (targets 365+ contaminants) and an Under-the-Sink System (targets 232+ contaminants)—designed for anyone who can’t alter their plumbing, or simply doesn’t want to.

Before we even get to your building’s plumbing, let’s talk about what could already be in your water…

According to the Environmental Working Group, 324 contaminants have been detected in U.S. tap water as of 2025. The EPA only regulates 90 of them. That means the majority of detected contaminants are legally allowed in our water. 

Here are just some of the most concerning dangers:

• PFAS (“forever chemicals”) have been found in the water serving an estimated 158 million Americans, and have been linked to cancer, hormone disruption, and immune system damage. 

• Fluoride was ruled by a federal court to pose an “unreasonable risk” to children’s developing brains. Plus, a 2025 meta-analysis found a statistically significant link between higher fluoride exposure and lower IQ in children.

• Hexavalent chromium (Chromium 6)—the cancer-causing chemical at the center of the Erin Brockovich case—still has no dedicated federal drinking water limit more than two decades later.

• Lithium is completely unregulated in U.S. drinking water, even as levels rise due to EV battery mining. The EPA links Lithium to kidney damage and thyroid dysfunction.

• Manganese has no enforceable federal limit and is often dismissed as a harmless “bathtub stain.” However, a landmark study found children exposed to higher levels scored significantly lower on IQ tests.

• Nitrates are regulated, but the “safe” limit may be dangerously outdated. A 2025 study found health risks at just 1% of the legal threshold. That means the current standard could be up to 100 times too high for widespread public safety.

• Microplastics (and nanoplastics) have no federal limit and have already been detected in human blood, organs, and brain tissue.

• Pharmaceuticals like birth control hormones, antidepressants, and antibiotics are completely unregulated in drinking water and have been detected in water serving at least 46 million Americans.

Remember, this is just the baseline. This is what could be in your water before it ever reaches your building. And if you live in an apartment, it could get worse from there…

Your city treats your water at the municipal level. But remember, that treatment happens before your water is distributed… 

Once it leaves the treatment plant, water travels through miles of aging underground infrastructure to reach your building. Then it passes through your building’s own pipes, solder, and fixtures before it reaches your faucet. 

At every stage of that journey, new contaminants can be introduced to the water. 

Every year, your local water utility publishes a Consumer Confidence Report (CCR). It tells you what contaminants were found in the public water supply and at what levels. And while that might sound reassuring, that report only analyzes your water before it enters your building.

It can’t tell you whether lead is leaching from aging plumbing in your walls, whether disinfection byproducts are forming as chlorine reacts with biofilm in old pipes, or what condition the service line connecting your building to the water main is in.

Living in an apartment doesn’t increase your exposure to every contaminant on the list. But if your building has older pipes, your water sits in those pipes longer between uses (especially overnight), and your landlord isn’t testing or treating the water—the risks could be far greater than someone in a newer home with modern plumbing.

After all, it’s not like you inspect the plumbing before you sign the lease. You can’t replace the service line connecting your building to the water main. And in most cases, your landlord isn’t required to test the water coming out of your faucet either.

The point is, that’s a lot of trust in a system you can’t see and didn’t choose.

Homes built before 1986 are more likely to have lead pipes, fixtures, and solder. And unlike contaminants that enter the water at the source, lead typically enters your water inside your own building, as it leaches from corroding plumbing between the service line and your tap.

The EPA currently estimates there are more than 9 million confirmed lead service lines in the U.S. A federal rule now requires all of them to be replaced, but full enforcement won’t take effect for years. 

In the meantime, if you’re living in a pre-1986 building, your water may be flowing through the very pipes the government is trying to remove.

When the EPA required water utilities to inventory their service lines in 2024, they found more than 20 million service lines made from “unknown material.”

That means no one has confirmed whether those pipes are lead, copper, plastic, or something else. And anything in those pipes could be interacting with your water. 

Bottom line?

Millions of buildings across the country are connected to the water supply by pipes made from unidentified materials. And until those materials are identified, there’s no way to know what those pipes are adding to your water on the way in.

Most leases prohibit modifications to plumbing or fixtures. HOA bylaws frequently restrict what you can install, especially anything that taps into shared infrastructure. And even if your landlord says “go ahead,” you’re investing in someone else’s property—and leaving it behind when you move… 

So what are you supposed to do?

We recommend investing in a high-quality, portable filtration system—like a Filtered Water Pitcher or our 3-Stage Under-the-Sink System.

The right filter doesn’t require a plumber, a landlord’s signature, or a hole in the wall. It just requires knowing what to look for…

Walk into any big-box store and you’ll find shelves lined with water pitchers and faucet attachments. Most of them use basic activated carbon to filter your water, which is fine for improving taste and reducing chlorine… 

But taste isn’t the problem:  

The contaminants that pose the greatest health risks are often the ones you can’t taste, smell, or see. Lead is odorless. PFAS are invisible. Pharmaceuticals don’t change the color of your water.

When choosing a filter that doesn’t require plumbing changes, here’s what actually matters:

• Contaminant range: How many contaminants does it target? A filter that catches 5 or 10 isn’t in the same league as one that targets hundreds.

• Independent testing: Is it tested by third-party labs? Manufacturer claims are just that: claims. Third-party testing is the only way to verify performance.

• Portability: Can you take it with you when you move? If you’re renting, your filter should be as portable as you are.

• Minerals: Some filters strip everything from water, including the healthy minerals your body wants. Unlike others, our Affinity® Filtration Technology targets what’s harmful and leaves what’s not.

A mainstream carbon pitcher from the grocery store might improve the taste of your water. But if you’re trying to protect yourself from lead, PFAS, and fluoride, you need something that goes far beyond carbon.

1. A Filtered Water Pitcher

A filtered water pitcher is a breeze to use, but not all pitchers are alike…

While most mainstream pitchers rely on ordinary carbon filters, ours is the only pitcher on the planet proven to protect you from 365+ dangerous contaminants—without stripping your water of beneficial minerals (like calcium, potassium, and magnesium). 

That’s a meaningful difference when you’re drinking, cooking, and making coffee with the same water every day.

2. A Portable Under-the-Sink System

This one surprises a lot of renters, because “under-the-sink” sounds like it requires plumbing work.

It doesn’t… 

Ours connects directly to your water line, which means you don’t need a separate, dedicated faucet to enjoy filtered water—and you don’t need to worry about plumbing, drilling, or any permanent modifications. In other words, it’s a 100% DIY install.

Better yet, it’s fully portable. When your lease is up, you disconnect it, pack it up, and bring it to your next apartment. It’s your filter, not your landlord’s fixture.

3. A Filtered Water Bottle

Maybe you’re not worried about the water in your apartment as much as the water you’re drinking everywhere else—at the office, at the gym, or on the go. Or maybe you just want an extra layer of protection without committing to a full kitchen setup.

A filtered water bottle gives you that. Fill it from any tap—at home, at work, at a hotel—and drink filtered water wherever you are.

Like a pitcher, it requires zero installation. And with our extra-large, 40-ounce Filtered Water Bottle, you’re not constantly refilling either.
