10 Best Water Filters for Renters & Apartments — Our Top Picks

Your apartment’s tap water might look fine, but that doesn’t mean it’s free from contaminants. Depending on where you live, there could be chlorine, lead, or other stuff you’d rather not drink.

A good water filter takes care of that. It’s also way more cost-effective than buying bottled water week after week, and you’re not adding to the plastic waste pile either.

Quick Comparison Chart

1. Big Berkey Gravity-Fed — Best Overall

The Big Berkey promises removal of 99.9% of bacteria from water along with food coloring, arsenic, fluoride, and other dangerous chemicals. It also effectively removes heavy metals like lead.

Although not the fastest filter, the quality of water it produces is top-notch. It takes about one to two hours for every 2.25-gallon batch, but the large capacity means you won’t need to refill constantly.

Its solid stainless steel tanks are sturdy and make sure sunlight doesn’t affect water quality. This gravity-fed filtration approach is one of the most reliable methods available. The two included carbon filters last about 3,000 gallons each, and you can add more filters if needed.

Since all filtration elements have different lifespans, it’s important to track when each one needs replacing. A piece of equipment that can last about 11 years, the Big Berkey is a solid investment for apartment dwellers.

Its large size does take up counter space, so if you prefer something compact, check other options below. However, at about 2 cents per gallon, it’s one of the most budget-friendly filters on this list.

2. Brita On-Tap Faucet — Best Faucet Mount

The Brita On-Tap removes up to 60 contaminants including harmful chemicals, metals, and sediment. With a capacity of 100 gallons, it can last your family about 4 months on average.

It’s conveniently equipped with indicators that flash green, amber, and red depending on filter condition. This lets you know exactly when to replace the cartridge.

The installation is easy and compatible with most water faucets. It takes a maximum of ten minutes, and you’ll be good to go.

It’s a budget-friendly option that effectively removes contaminants. However, it’s meant for treated water since it doesn’t remove bacteria and germs.

All Brita faucet filters use the same cartridge, so if one model gets discontinued, your replacement cartridges still work with other Brita models. The filter comes with a one-year warranty.

While not suitable for heavily contaminated water, it works effectively on urban sources. Its sleek white finish blends perfectly with your kitchen.

3. Soma 10-Cup Pitcher — Best Design

With a wooden handle and a compact design, the Soma Water Filter pitcher is as beautiful as they come. You can store it in the fridge or set it on the table for daily use.

The pitcher filters out substances like copper, chlorine, mercury, zinc, and cadmium. The filter holds up to 40 gallons before it needs replacing.

It’s easy to fill, doesn’t take up space, and does the job with style. While it doesn’t completely remove all harmful particles, it filters many impurities so chlorine taste and smell won’t bother you.

The filter housing is made from renewable materials, leaving a smaller carbon footprint. That makes it an eco-friendly option for environmentally conscious apartment dwellers.

It’s also great for families since the automatically opening lid makes filling easy. It holds 10 cups and is shatterproof glass, so you won’t worry about kids breaking it.

Just avoid overfilling and pour with some force to prevent water from dribbling over the sides.

4. ZeroWater 6 Cup Pitcher — Best Purification

The ZeroWater pitcher promises to deliver the purest water possible for drinking. It comes with a water quality meter that helps you measure dissolved solids to make sure what you’re drinking is completely safe.

Its five-stage filtration process weeds out all contaminants and dissolved solids, including lead. The difference between tap water and ZeroWater-filtered water is remarkable, as all odors and foul tastes are removed.

The pitcher is NSF certified to reduce heavy metals and virtually all dissolved solids. It also includes a standard conductivity tester for determining mineral content in water.

With double the contaminant-grabbing ability and anion-exchange paste, ZeroWater’s cartridge is stronger than many other pitcher options. All unnecessary materials can be prevented from accumulating in landfills through their effective recycling system.

With top-tier filtration technology, it’s one of the better apartment pitcher options. The water it produces is comparable to distilled water in purity.

5. LifeStraw Go Bottle — Best Portable

Love to go camping? This water filter bottle might be your new best friend.

If you travel often and filtered water is important to you, LifeStraw’s Go Water Filter Bottle is one of the best portable options available.

The BPA-free, leak-proof plastic bottle is quite durable and filters water from all sources. Its integrated filter with activated carbon capsules removes all the chlorine, bacteria, and other contaminants that make water taste bad.

It’s easy to clean since the silicone mouthpiece can be removed and filters can be replaced. It doesn’t use any iodized resin, so filtered water has zero aftertaste.

The bottle also removes 99.9% of all waterborne bacteria, protozoan parasites, and microplastics. Carbon capsule replacements are widely available and easy to purchase.

Some drawbacks include difficulty drinking through the filter straw. It’s also not suitable for any liquid other than water, as the filter traps flavor and can cause odor buildup.

Since the filter takes up internal space, the bottle holds less water than a standard bottle. Available in blue and grey, it’s a handy tool for apartment dwellers who want filtered water on the go.

6. APEC 5-Stage RO — Best Under-Sink

For under-sink apartment filtration, the APEC 5-Stage filter comes highly recommended. This reverse osmosis system employs basic RO filtration with a capacity of purifying 50 gallons per day across 5 stages.

Because of its larger size, it takes some time to refill once the tank is empty. If you can be patient with that, it’s definitely a worthy investment.

It’s easy to install and takes about an hour with the included instructions. All filters can be changed without special tools.

The system includes a lead-free chrome faucet and FDA-certified food-grade tubing for maximum safety. It also carries WQA certification, making it efficient for both well water and tap water.

With a 3:1 wastewater-to-pure-water ratio, the APEC filter is considered very effective. A 2-year manufacturing warranty provides additional peace of mind.

Filters are long-lasting, with 3 out of 5 needing replacement about twice a year and the remaining two lasting 2-3 years. It also includes extra filters, so you won’t incur additional costs for at least 12 months.

7. CuZn UC-200 — Best Long-Lasting

The CuZn UC-200 is perfect for large families as it has enormous capacity and doesn’t need constant refilling. With a 50,000-gallon capacity, it can last you up to 5 full years.

Instead of requiring an extra faucet, the filter connects directly to the cold-water line. This makes installation easier and keeps your apartment looking clean.

It has a high-performance three-stage filtration process. In the first stage, micro sediment membranes filter out larger particles like sand and silt.

In the second stage, KDF-55 filtration media removes water bacteria, chlorine, and heavy metals. The third stage uses coconut shell activated carbon to remove bad odors, tastes, and contaminants like herbicides.

What separates it from other carbon filters is that its bacteriostatic KDF-55 media prevents bacteria from growing on the filter itself. This keeps your water from getting contaminated by the filter over time.

This apartment water filter boosts the appearance and taste of your drinking water. The easy installation means you can set it up yourself without calling a plumber.

8. Home Master HydroPerfection — Best for Well Water

Like other Home Master RO versions, this whole house filter comes with extremely efficient pre and post-carbon filters and reverse osmosis membranes. It also has materials that effectively filter iron.

Since water from private wells is more contaminated with dangerous pathogens than treated tap water, it’s unsafe for consumption without proper filtration. The HydroPerfection fixes this easily by destroying 99.99% of germs, bacteria, and viruses with its UV chamber.

This is why it produces water quality similar to distilled water. It also shows great results on both lead and chlorine tests, removing nearly all chlorine from the water.

The filter rejuvenates water with minerals like calcium and magnesium. This prevents tank degradation and improves overall taste.

However, despite its great performance, it doesn’t offer completely unique features. The same effect can be found in some cheaper options, so depending on your budget, you could get similar value for less money.

9. Culligan FM-15A — Best Budget

Even though the Culligan is small and simple looking, it’s actually a pretty powerful filter. This NSF-certified device is excellent at removing foul tastes, odors, and chlorine from tap water.

It works like magic when producing fresh water, taking only 30 seconds to fill a cup. It’s also extremely efficient at removing even the tiniest particles of dust, sand, and lead.

You don’t need any experience with tools to install it. You can fasten it to the faucet in barely any time, making it perfect for apartment renters.

If you’re someone who wants filtered water wherever you go, this tiny filter is handy for traveling from city to city. Its compact size makes it easy to pack and take along.

However, its small size means limited filtering capacity. You’ll need filter replacements at least twice a month with regular use.

One way to extend filter life is to switch it off during activities that don’t require filtered water. But frequent switching can cause leakage where unfiltered water mixes with filtered water.

It’s also not compatible with some faucets including certain pull-out and pull-down models. Check compatibility with the manufacturer before purchasing.

10. Aquagear 8-Cup Pitcher — Best Eco-Friendly

The Aquagear pitcher uses filtration material consisting of numerous 2-micron pores that do a great job trapping pollutants from the water. Even despite its small size, the powerful cartridge reduces contaminant levels by up to 99%.

The pitcher holds 8 cups of water at a time, which is the recommended daily intake amount. If you drink more than that, refilling is easy thanks to the top lid with a pressure valve.

It’s very durable and can handle about 150 gallons of tap water. That’s quite a lot compared to competitors that only last 2 to 3 months.

The Aquagear pitcher can last about 6 months before needing a replacement filter.

However, the pitcher isn’t suitable for well water containing algae and other harmful microorganisms that require stronger filtration. It’s designed especially for treated municipal tap water.

This pitcher is perfect for a small family that doesn’t want to deal with complicated installations. It delivers fresh drinking water every day in the easiest way possible.

How We Evaluated

We evaluated each apartment water filter based on the following criteria:

Buying Guide: Finding the Best Water Filter for Your Apartment

What Type of Water Filter Is Best for Apartments?

Your choice depends on your living situation and water quality. Pitcher filters and faucet mounts require zero installation, making them the most renter-friendly options.

Under-sink systems provide deeper filtration but may need landlord approval. Gravity-fed systems like the Big Berkey sit on the counter and need no plumbing modifications.

What Should You Look For?

• Contaminant removal — Check which contaminants the filter targets. Carbon filters improve taste and remove chlorine, while RO systems remove virtually everything.
• Filter capacity — Higher gallon ratings mean less frequent replacements. The CuZn UC-200 lasts years, while basic faucet mounts may need monthly changes.
• Installation type — Pitchers and faucet mounts need nothing. Under-sink systems need plumbing access. Consider what your lease allows.
• Water source — Tap water from city utilities needs less filtration than well water.
• Certifications — Look for NSF or WQA certifications to verify filtration claims.

Carbon vs. Reverse Osmosis

Carbon filters preserve beneficial minerals while removing chlorine, bad tastes, and certain chemicals. They’re ideal if your tap water is already treated and safe.

Reverse osmosis systems remove virtually everything, including dissolved solids, bacteria, and heavy metals. Choose RO if you need the deepest purification. Learn more in our guide to countertop reverse osmosis filters.
