In-depth reviews

PUR PLUS Faucet Mount review

Who it is for: Renters and anyone who wants better tasting water at the sink without tools or drilling. This faucet-mounted unit clicks onto most standard faucets and switches between filtered and unfiltered water with a lever, so you do not waste filter life on dishwashing.

How it works and what it targets: The PUR PLUS uses a carbon block with ion-exchange media to reduce chlorine taste and odor and address health-related contaminants like lead and mercury. Many models are certified to NSF/ANSI 42 for aesthetic improvements and 53 for contaminants such as lead. Filter life is typically around 100 gallons or about 3 months, and an indicator helps you know when to change it.

What it is like to live with: Installation usually takes 5 minutes. Flow through the filter is slower than your bare faucet, which is normal for carbon filtration. The body is bulkier than an aerator, and it may not fit pull-out or pull-down sprayer faucets, so check compatibility. Expect the flow to slow near the end of a filter’s life, especially if your water has a lot of sediment.

Drawbacks: Faucet mounts add weight to the spout and can drip if the adapter is not tightened correctly. Cartridges need more frequent replacement than under-sink systems, and hot water should not run through the filter. If you cook for a crowd, the slower flow may feel limiting.

Compare it: Against the Brita Elite Longlast+ Pitcher, the PUR faucet is more convenient for cooking because you get on-demand filtered water. Compared to the Aquasana AQ-5200 Under Sink, it is easier to install but generally covers fewer contaminants and has a shorter filter life.

Brita Elite Longlast+ Pitcher review

Who it is for: Households that want chilled, clean-tasting water with strong lead reduction and a low ongoing cost. Pitchers are a great fit for renters, offices, and families who like cold water on hand.

How it works and what it targets: The Brita Elite Longlast+ uses a dense carbon block designed to reduce chlorine taste and odor, as well as health-related contaminants such as lead and some industrial byproducts. The standout feature is longevity. One filter can last up to 120 gallons or about 6 months, far longer than standard pitcher filters.

What it is like to live with: Setup is simple. Soak and rinse the cartridge, drop it in, and fill. The water tastes noticeably cleaner once chilled. Refills take a few minutes to percolate through the media, and the large 10-cup format gets heavy when full. A simple timer or electronic indicator helps you track replacement.

Drawbacks: Pitchers require counter space during refills and shelf space in the fridge. Flow is slower than a faucet-mounted option, and a pitcher will not help with cooking water unless you plan ahead. Pitchers are best for municipal water. They are not designed to handle very high sediment or reduce dissolved solids like fluoride or nitrate.

Compare it: Versus the PUR PLUS Faucet Mount, the Brita is better for chilled water but less convenient for filling pots. Compared with the Aquasana AQ-5200 Under Sink, it is cheaper to install and maintain, but it cannot match the breadth of contaminant reduction or the convenience of a dedicated drinking faucet.

Aquasana AQ-5200 Under Sink review

Who it is for: Cooks and families who want high-quality filtration at the sink without the complexity of a reverse osmosis system. If you are focused on lead, cysts, and emerging contaminants like PFAS, this is a strong fit.

How it works and what it targets: The AQ-5200 is a two-stage under-sink system that uses a carbon block and ion exchange media to tackle a broad contaminant list. Models in this line carry certifications such as NSF/ANSI 42 and 53 for chlorine and heavy metals, and 401 for certain pharmaceuticals and PFAS like PFOA and PFOS. The included dedicated faucet keeps filtered water separate from your main tap. Capacity is typically around 500 gallons or 6 months per set of cartridges.

What it is like to live with: Expect a compact bracket that mounts to the cabinet wall and quick-connect hoses that simplify install. Many homeowners finish in about an hour with an adjustable wrench. Flow through the dedicated faucet is steady but lower than your main tap, which is normal for fine filtration. Taste and odor improve immediately, and the system wastes no water during use.

Drawbacks: You will need a hole for the included faucet, so check your sink deck or use an available sprayer or soap-dispenser knockout. If you prefer filtering directly at your main faucet, this separate-spout design may feel less convenient. Under-sink carbon systems do not reduce total dissolved solids and are not a solution for nitrate on their own.

Compare it: Choose this over the PUR PLUS Faucet Mount if you want stronger contaminant coverage and longer-lasting filters. If you need fluoride or nitrate reduction, the APEC ROES-50 reverse osmosis system is the better pick, though it is more complex.

APEC ROES-50 Reverse Osmosis System review

Who it is for: Households dealing with high TDS, nitrate, fluoride, or a mix of stubborn contaminants, including many well-water users. If you want bottled-water clarity at home, RO is the most thorough option for the price.

How it works and what it targets: The ROES-50 combines sediment and carbon prefilters with a reverse osmosis membrane and a final polishing stage. The membrane rejects a wide range of dissolved contaminants, including arsenic, chromium, fluoride, nitrate, and lead. Typical production is up to 50 gallons per day, stored in a small tank under the sink.

What it is like to live with: Installation takes longer than a basic under-sink filter because you will add a drain saddle and a dedicated faucet. Once running, water tastes very clean, often with a dramatic TDS drop. Prefilters are usually replaced yearly, and the membrane commonly lasts 2 to 3 years depending on your water quality and usage.

Drawbacks: RO systems send a portion of water to drain during filtration, so they are less water-efficient than carbon-only systems. Flow to the faucet depends on tank pressure and is slower than your main tap. Some people find RO water tastes flat due to lower mineral content. A simple remineralization cartridge or blending with a small amount of unfiltered water can improve flavor for coffee and tea.

Compare it: If your main concerns are lead and PFAS with normal TDS, the Aquasana AQ-5200 is simpler and wastes no water. If you have measurable nitrate, fluoride, or high TDS, the ROES-50 is the right call. Fridge filters like EveryDrop improve taste but are not a substitute for RO in these cases.

EveryDrop by Whirlpool Refrigerator Filter review

Who it is for: Anyone using a refrigerator with a built-in dispenser or ice maker who wants reliable, manufacturer-matched filtration and a simple twist-in replacement experience.

How it works and what it targets: EveryDrop is Whirlpool’s OEM line that covers many Whirlpool, Maytag, Amana, KitchenAid, and JennAir models. These filters are designed for proper fit and flow, and many are certified to NSF/ANSI 42 for taste and odor and 53 for select health-related contaminants, including lead for certain models. Typical life is 6 months, which often corresponds to a few hundred gallons based on dispenser use.

What it is like to live with: Replacements are straightforward. Twist out the old cartridge, snap in the new one, and run a few quarts to flush. Taste improves quickly, especially if your city water has a strong chlorine smell. Because the filter sits in the fridge or grille, it saves cabinet space and keeps the kitchen tidy.

Drawbacks: OEM filters cost more than many third-party cartridges. Aftermarket options can be fine if they carry valid NSF/ANSI certifications and fit correctly, but fit and sealing are common pain points. A fridge filter only treats water at the dispenser and ice maker. If you need filtered water at the sink for cooking, pair it with a pitcher, faucet filter, or an under-sink system.

Compare it: Versus the Brita Elite Longlast+ Pitcher, a fridge filter is more convenient for dispensing cold water and ice but typically costs more per year. Compared with the Aquasana AQ-5200, it is easier to install but does not cover as many contaminants.

How to choose the right kitchen water filter

Start with your water. If you are on city water, check your utility’s annual Consumer Confidence Report for what is in your supply, then adjust for what your household tastes and smells at the tap. If you use a private well, get a lab test at least annually for bacteria, nitrate, arsenic, and other local concerns. A simple handheld TDS meter will not identify specific contaminants, but a high reading can confirm that a reverse osmosis system makes sense if taste, scale, or nitrate are issues.

Match your goals and home constraints to the filter type:

• Taste and odor only: Pitcher, faucet-mount, or OEM fridge filter with NSF/ANSI 42.
• Lead and other metals: Look for NSF/ANSI 53 on faucet, pitcher, or under-sink carbon systems.
• PFAS and pharmaceuticals: Under-sink systems with NSF/ANSI 401 or RO with NSF/ANSI 58.
• Nitrate and fluoride: Reverse osmosis is the practical home option for most families.

Consider convenience and total cost. Faucet filters are easy to install and great for renters. Pitchers are inexpensive to start and perfect for chilled water, but they require refilling. Under-sink carbon systems deliver stronger coverage with modest maintenance and no water waste. Reverse osmosis gives the most thorough reduction of dissolved contaminants but uses cabinet space and sends some water to drain during filtering.

Finally, check the basics: capacity and filter life, flow rate, the space you have for installation, compatibility with your faucet or fridge model, and cartridge costs over 3 to 5 years. Certifications matter. Look for NSF/ANSI marks appropriate to your goals, and choose reputable brands with clear performance data.

Installation, replacement, and maintenance tips

• Faucet-mounted filters: Remove your aerator, choose the right adapter, hand-tighten, then snug gently with a wrench if needed. Run cold water only, and flush a new cartridge per the manual. If you have a pull-out sprayer, a faucet mount will likely not fit.
• Pitchers: Soak and rinse the cartridge, wash the reservoir and lid, then fill. Expect the first full reservoir to run through slowly. Keep the pitcher clean, and store it in the fridge to improve taste.
• Under-sink carbon systems: Shut off cold water, mount the bracket, push-fit hoses, and install the dedicated faucet in a spare knockout if available. Flush new cartridges for several minutes and check for leaks after your first few uses.
• Reverse osmosis: In addition to the faucet, you will install a drain saddle. Label your prefilters and note the installation date. Plan for yearly prefilter changes and a membrane swap every 2 to 3 years. Never run hot water through any carbon stage.
• Fridge filters: Use the model number printed inside the refrigerator or on your current cartridge to match the correct replacement. After installing, dispense and discard several quarts to flush air and carbon fines.

Set reminders for replacement by time and gallons. Use the indicator on your device, put a sticker inside the sink cabinet with the date, and set a recurring phone reminder. If taste or flow changes suddenly, investigate early. Check for a kinked line, expired cartridge, or a clogged sediment prefilter if your system has one.

Final thoughts

If you want a quick, low-commitment upgrade at the sink, start with the PUR PLUS Faucet Mount. For chilled water and low ongoing costs, the Brita Elite Longlast+ Pitcher is the best value. If you cook a lot and want stronger contaminant coverage at the tap, go with the Aquasana AQ-5200 under-sink system. If your tests show high TDS, nitrate, or fluoride, the APEC ROES-50 is the right tool. And if your fridge has a dispenser, an EveryDrop OEM filter makes daily drinking simple and consistent. Pick the one that fits your home and goals, then keep up with filter changes so it performs like day one.

FAQ

Which filter type is best if I care about lead, PFAS, and chlorine taste?

For a strong balance of coverage and simplicity, choose an under-sink carbon system like the Aquasana AQ-5200 that carries NSF/ANSI 42 and 53 for taste and metals and 401 for emerging contaminants such as PFAS. If your water also has high dissolved solids or nitrate, step up to a reverse osmosis system like the APEC ROES-50.

Will a pitcher filter improve coffee more than a fridge filter?

Often, yes. Coffee prefers consistent water with low chlorine and fewer odd flavors. A long-life pitcher like Brita Elite Longlast+ can deliver more stable results than some OEM fridge filters, especially if your fridge filter is overdue for replacement. For the cleanest flavor, reverse osmosis or a high-quality under-sink carbon filter is even better.

How do I know a faucet filter will fit my sink or a cartridge will fit my fridge?

For faucet filters, verify you have a standard threaded faucet and not a pull-out or pull-down sprayer. Most kits include multiple adapters. For refrigerators, match the model number inside the fridge or your current cartridge number to the exact EveryDrop filter type. Avoid guessing. A mismatched filter can leak or restrict flow.

Does reverse osmosis remove fluoride and nitrates, and is it overkill for city water?

Reverse osmosis is one of the most effective home options for reducing fluoride and nitrate. If your city water tastes fine and you are mainly concerned with chlorine or lead, an under-sink carbon system is simpler. Choose RO when you need lower TDS, fluoride, nitrate, or a broad safety margin for a wide range of dissolved contaminants.

What is the easiest way to remember filter changes?

Use two reminders. First, put a dated sticker on the filter housing or inside the sink cabinet. Second, set a recurring phone reminder for the rated lifespan, such as 3 months for faucet filters, 6 months for under-sink and fridge filters, and 12 months for many RO prefilters. If taste or flow changes early, replace sooner.
