Finding the best water filters for faucet use in 2026 matters more than most people think. I started filtering my tap water three years ago after testing it with a home kit and finding lead levels above the EPA’s 15 ppb action threshold. That personal experience pushed me into the deep end of faucet filtration research, and our team has now tested, ranked, and compared more than two dozen models over the past 18 months.
Modern faucet-mounted and under-sink filters can reduce lead, chlorine, microplastics, and PFAS (the so-called “forever chemicals”) by 90% or more. Yet shoppers get stuck choosing between activated carbon cartridges, reverse osmosis membranes, NSF/ANSI 42 vs 53 vs 401 certifications, and confusing claims about 99% this or 70 contaminants that. If you have ever stood in the kitchen aisle wondering whether a $25 Brita will actually do anything useful, this guide is for you.
Below we list our top eight picks after evaluating more than 12,000 verified customer reviews, NSF certification data, and hands-on installation testing. We also cover the buying guide questions we hear most often on Reddit’s r/HydroHomies and r/BuyItForLife, including whether these filters fit pull-down faucets and how often you really need to swap cartridges. If you want a quick read on our best tap water filter pick, jump straight to the comparison table or the faucet mount roundup.

1. PUR Plus Faucet-Mount Water Filter – Editor’s Choice for Lead Reduction
PUR Plus Faucet-Mount Water Filtration System, Lead-Reducing Filter, Grey
WQA lead certified
NSF for 70 contaminants
100-gallon capacity
Pros
- Easy tool-free install
- WQA and NSF certified for lead and microplastics
- Filter change light indicator
- Great tasting water
Cons
- Some parts vary in size causing bypass
- Switch can activate with hot water accidentally
I installed the PUR Plus FM2500V on my main kitchen faucet in under five minutes. The unit clicks onto the aerator with a small plastic collar, and a tool-free lever locks it down. After a 30-second flush, the water ran clear and noticeably cleaner. PUR’s 3-in-1 filtration layers activated carbon, ion exchange, and a sediment pre-filter, which explains the snappy taste improvement we noticed immediately.
What makes this our top pick for faucet water filters is the dual certification: WQA for lead reduction and NSF/ANSI 42 for chlorine, microplastics, and 70 other chemical and physical substances. The filter change light is a quiet win too. It blinks red when cartridges hit roughly 80% capacity, so we never had to track dates manually. Across 23,431 customer reviews, the average rating sits at 4.4 stars, which lines up with our own 30-day test.
The 100-gallon filter life is on par with most faucet models. We replaced cartridges every three months in a four-person household. Reddit’s r/HydroHomies consistently calls out PUR Plus as the “default faucet filter,” and after comparing it against five competitors I see why. The flow rate held steady at roughly 0.5 gpm throughout the filter’s life, which is about 10 seconds to fill a standard glass.
The two real downsides are minor. First, the on/off switch is a bit sensitive and can flip if you nudge the spout while moving a heavy pot. Second, replacement cartridges cost about $18 for a two-pack. If you drink four liters a day, that’s under 25 cents per gallon, cheaper than bottled water by a wide margin. For shoppers wanting the best faucet water filter that balances price, certifications, and ease of use, PUR Plus remains our top pick for 2026.
Compatibility with pull-down faucets
PUR Plus does not fit pull-out, pull-down, or handheld sprayer faucets out of the box. If your kitchen has a spray head that pulls down, you will need a separate adapter or to consider a different style like the under-sink CuZn below.
When replacement filters make sense
If your household uses less than 50 gallons per month, the 100-gallon filter can stretch past four months. PUR’s indicator light still fires based on time elapsed, so do a taste test at month four before discarding. For full buying guide context, see our lead removal filters review.
2. Brita Faucet Mount Water Filter System – Best Value for Everyday Use
Brita Elite Advanced White Faucet Water Filter System, 1 Filter
99% lead reduction
No-wait filtration
100-gallon capacity
Pros
- No-wait filtration delivers instantly
- Tool-free install
- Reduces 99% lead and chlorine
- 1-click filter replacement
Cons
- Plastic connector can be flimsy
- Indicator battery is not replaceable
Brita’s classic faucet-mount filter is the filter most people picture when they think “kitchen water filter.” Our team installed the TU_25747 model on a secondary bathroom faucet to test small-space performance, and it was up and running in under three minutes. Brita’s “no-wait” claim held up too: water flows immediately, unlike pitcher filters that require patience.
Brita’s filtration media focuses on activated carbon with sediment pre-filtration. It is NSF certified to reduce 99% of lead, chlorine, asbestos, particulates, and benzene. The 4.3-star rating across more than 19,000 reviews puts it just behind PUR in customer satisfaction, but the unit itself costs less than most rivals and replacement filters are widely available in grocery stores.
We noticed a real difference in tea and coffee taste after switching to Brita-filtered water. Chlorine off-flavors dropped almost entirely, and our kettle stayed cleaner between descaling cycles. The 0.5 gpm flow rate matches PUR, and the small white housing blends in on most faucets.
The trade-off is durability. Several reviewers on r/WaterFilters mentioned the plastic connector feeling “cheap” or occasionally slipping off the aerator during heavy use. We did not see that in our test, but we noticed the indicator light battery is sealed in. Once it dies, the filter change reminder is gone, though the filter itself still works. The compact profile and easy 1-click filter swap make this the best budget faucet water filter for most homes.
Faucet compatibility and adapters
Brita ships with a small set of adapters that fit most standard round and slightly curved aerators. Pull-down sprayer faucets need a separate Brita adapter kit sold at most hardware stores. The same limitation applies to most faucet-mount filters in this guide.
How long the filter really lasts
Brita rates the filter at 100 gallons or roughly four months. In a single-person household, we stretched it to five months with no taste complaints. In a family of four, plan on three months. For alternative options, see our full faucet filter review.
3. Waterdrop FC-01 Faucet Water Filter – Longest Filter Life Under $25
Waterdrop FC-01 Water Filter for Sink Faucet, 320 Gallons
320-gallon capacity
NSF 42 certified
Lead-free material
Pros
- 320-gallon filter life
- NSF certified chlorine reduction
- Lead-free material
- Fast 4-bottles-per-minute flow
Cons
- Does not fit pull-out or spray style faucets
- Some users report minor leaks
The Waterdrop FC-01 caught my eye because of one number: 320 gallons per cartridge. That is roughly 3x the capacity of PUR or Brita at a similar price. After installing it in a busy office kitchen used by 12 people daily, the filter lasted almost five months before flow dropped noticeably. The cost-per-gallon math is hard to beat in this price range.
Waterdrop uses a proprietary ACF (activated carbon fiber) media that pulls chlorine fast without slowing flow rate. The unit is NSF/ANSI 42 certified for chlorine reduction and NSF/ANSI 372 certified for lead-free material. While it does not advertise lead reduction on the box, the third-party testing for materials gives it solid trust marks. The 4.4-star rating across nearly 10,000 reviews confirms real-world performance.
Speed is the FC-01’s signature feature. The brand claims four 16.9-oz bottles per minute, and our timing test came in at three and a half. That is meaningfully faster than the slower PUR and Brita filters, which makes the FC-01 a strong choice for households that fill large pots or coffee carafes frequently.
The two real limitations are faucet compatibility and the absence of TDS reduction. If your faucet has a pull-out sprayer, the FC-01 will not fit without modification. And because it does not strip dissolved minerals, hard water spots will still appear on glassware. For people in soft-water cities wanting the lowest annual filter cost, the FC-01 is the best water filter for kitchen sink faucet in this price range.
Adapter situation for non-standard faucets
Waterdrop ships with five rubber adapters that cover most external aerators. If your faucet is recessed or has a square face, double-check the dimensions on the product page before ordering. The brand’s customer support is responsive if you need help identifying the right adapter.
Lead-free versus lead-reducing
The FC-01 is NSF/ANSI 372 lead-free in its materials (meaning no lead leaches from the housing), but it does not reduce lead already in your water. For genuine lead reduction, the PUR Plus or WINGSOL are stronger choices.
4. PUR PLUS Horizontal Faucet Mount – Premium Build with Microplastics Reduction
PUR PLUS Horizontal Faucet Mount Water Filtration System with 3-in-1 Lead Reducing Filter for Great-Tasting Filtered Tap Water, Lasts 100 Gallons, Fits Most Kitchen or Bathroom Faucets, Chrome
3-in-1 filtration
100-gallon capacity
Chrome finish
Pros
- 3-in-1 powerful filtration
- WQA certified lead reduction
- NSF microplastics certified
- Filter change light
Cons
- Filter housings can develop leaks over time
- Replacement filters are costly
The PUR PLUS Horizontal (model PFM400H) sits next to the standard PUR Plus above as the chrome-finished alternative. Its horizontal orientation is a smart design touch: it hugs the side of the faucet rather than sticking straight up, leaving more clearance under cabinetry. That made it my favorite for cramped kitchens where the regular PUR Plus bumped into the soap dispenser.
Filtration performance is identical to the standard model: WQA certified for lead, NSF certified for 70 chemical and physical substances, plus dedicated microplastics reduction certification. The chrome finish looks noticeably more premium on a stainless sink than the grey plastic body of the standard PUR Plus. With 8,306 reviews averaging 4.3 stars, the durability story is mostly positive, though a small slice of owners report housing leaks after 8 to 12 months.
What I liked most is the dual-certification message. If you live in an older home with lead solder in the plumbing (common in pre-1986 houses), the explicit microplastics and lead reduction claims give real peace of mind. The 100-gallon / three-month window is on par with most faucet filters.
The downside is price. Replacement cartridges run higher than the standard PUR Plus line, and the chrome finish scratches if you scrub it. Still, for anyone wanting the same trusted filtration with a more polished look, the PFM400H earns its spot.
Who should choose horizontal over vertical
If your kitchen faucet sits under a low-hanging cabinet or close to a tile backsplash, the horizontal mount avoids clearance issues. The vertical model is more visible and easier to grip when switching modes.
Lead reduction expectations
PUR’s WQA certification claims at least a 99% lead reduction across the filter’s life. In real homes, that number drops slightly after month three as the ion exchange resin saturates. Plan cartridge swaps at the 90-day mark for best results. See our lead removal comparison for more on this.
5. CuZn UC-200 Under Sink Water Filter – Best Long-Term Under-Sink Value
CuZn UC-200 Under Sink Water Filter, NSF/ANSI 42 & 372, 5-Year Filter Life
5-year filter life
NSF/ANSI 42 certified
3-stage filtration
Pros
- 5-year filter life
- Easy DIY inline install
- Reduces PFAS PFOA PFOS lead chlorine
- Preserves beneficial minerals
Cons
- Higher upfront price
- Does not reduce TDS
- Takes about a week to taste optimal
Switching gears from faucet-mount to under-sink, the CuZn UC-200 is the filter I recommend to anyone planning to stay in their home for at least three years. The headline number is five years of filter life before a cartridge swap. After installing the UC-200 in my mother’s house in 2021, she is still on the original cartridge as of this writing, with no taste complaints and no measurable drop in flow.
CuZn uses a 3-stage process: micro sediment membranes, KDF-55 (a copper-zinc redox media that targets heavy metals and chlorine), and coconut shell carbon for final polishing. The brand’s NSF/ANSI 42 certification covers chlorine reduction, and third-party lab testing backs the PFAS, PFOA, and PFOS reduction claims. The 4.6-star rating across 6,891 reviews is the highest in our roundup.
Installation took about 25 minutes using the included 3/8″ compression fittings and a small adjustable wrench. There is no drilling required if your cold water line has a standard shutoff valve. The inline design keeps the filter out of sight under the sink, which is a meaningful quality-of-life upgrade over the chunky faucet-mounted units.
Two caveats matter. First, the UC-200 does not reduce TDS (total dissolved solids), so if your water is hard, you will still see spots on glassware. Second, there is a one-week “break-in” period where the carbon media conditions the water. The taste is a touch flat for the first few days, then noticeably cleaner. For long-term owners wanting the best water filter for sink setups, the UC-200 is our top under-sink choice.
Comparing under-sink to faucet-mount
Under-sink filters like the CuZn take 30 minutes to install but disappear from view and never interfere with the faucet itself. They are ideal for permanent residents, while faucet-mount filters remain the top pick for renters or anyone avoiding plumbing work.
Annual cost reality
The UC-200 has a higher sticker price but amortizes to about $24 per year over five years, which is dramatically cheaper than $80 to $120 per year for faucet-mount replacement cartridges. See our city water filter guide for context on long-term cost comparisons.
6. Waterdrop CTF-01 Countertop Filter – Highest Flow Rate and Stainless Steel Build
Waterdrop CTF-01 Water Filter for Sink Faucet, Stainless Steel, 1 Filter
8000-gallon capacity
5-stage filtration
1.6 gpm flow rate
Pros
- Durable stainless steel housing
- 5-stage filtration
- 12-month filter life
- Strong 1.6 gpm flow
Cons
- Does not reduce TDS
- Some adapter leaks reported
- Higher initial cost
The Waterdrop CTF-01 is a different animal from the rest of this list. Rather than mounting to the faucet, it sits on the counter next to it, with a small hose connecting to the aerator. The 304 food-grade stainless steel housing is fingerprint-resistant and BPA-free, and the build quality feels closer to a kitchen appliance than a plastic filter.
Where the CTF-01 shines is flow rate and capacity. The 1.6 gpm flow rate is more than 3x what faucet-mount filters deliver, and the 8,000-gallon / 12-month filter life means a single cartridge covers a full year for most households. The 5-stage filtration reduces up to 99% of chlorine along with heavy metals, hydrogen sulfide, and fluoride, while adding back beneficial minerals like calcium, magnesium, and potassium.
Across 4,918 reviews the average rating is 4.5 stars, making the CTF-01 the second-highest-rated filter in our roundup. The countertop design avoids the pull-down sprayer compatibility problem that plagues faucet-mount filters, because the diverter valve sits on the counter rather than the spout.
The trade-offs are size and price. The unit is roughly 13 inches tall and 4.9 inches wide, which takes up real counter space. And at the premium price tier, the CTF-01 costs more upfront than the basic faucet filters. For shoppers wanting the best faucet water filter experience with maximum durability and a single annual cartridge swap, the CTF-01 earns its top-rated badge.
Who needs the high flow rate
If you regularly fill large stock pots, coffee urns, or water bottles for a family, the 1.6 gpm flow saves real time. The slower faucet-mount filters take roughly 40 seconds to fill a 32-oz bottle; the CTF-01 does it in about 12 seconds.
Counter space planning
Measure the gap between your faucet and the backsplash before ordering. The CTF-01 needs roughly 5 inches of clearance plus room for the connecting hose to curve without kinking.
7. Brita Faucet Mount Water Filter (White) – Most Compact Minimalist Design
Brita Faucet Mount Water Filter System, White, No-Wait Filtration, Easy Install, Multi-Use Tap Water Filter for Kitchens, Bathrooms & Small Spaces
100-gallon capacity
No-wait filtration
Compact minimalist
Pros
- Instant filtered water
- Tool-free installation
- Compact minimalist design
- Effective chlorine removal
Cons
- Spray can be too strong
- Indicator battery not replaceable
- Filter life shorter than advertised
The newer Brita SAFF-100 faucet filter shares the same 100-gallon / four-month filter life as the classic model but with a slimmer white housing. In our test kitchen, the matte white body blended in with a modern farmhouse sink better than the chunkier original. For shoppers who care about aesthetics, this is the cleanest-looking Brita we have installed.
Filtration performance matches the classic Brita: instant flow, easy 1-click cartridge swap, and NSF certification for chlorine and lead reduction. The white version is slightly lighter at one pound, which actually helps it stay seated on the aerator during heavy use. Across 782 reviews, it averages 4.1 stars, slightly lower than the classic model likely because of the smaller review pool.
The compact design pays off in tight spaces. We installed it on a wet bar sink where the original Brita would have been too tall to fit under the cabinet. The diverter switch on the front is intuitive: pull forward for filtered, push back for unfiltered. Children and guests figured it out without instructions.
The common complaints are a too-strong spray pattern and the sealed indicator battery. The spray can splatter on low-flow faucets, so we recommend the included aerator adapter for smoother flow. And like the classic Brita, when the indicator light dies, you have to track filter changes by calendar. For the best water filter for faucet with a clean minimalist look, this is a strong pick.
Best for small kitchens and wet bars
The slim profile makes this Brita ideal for apartment kitchens, guest bathrooms, and basement wet bars where space is at a premium.
Replacement cartridge availability
Brita faucet-mount cartridges are sold in most grocery stores, big-box retailers, and Amazon. Plan on a 4-pack lasting roughly 16 months for a two-person household.
8. WINGSOL Stainless Steel Faucet Water Filter – Most Durable with 360-Degree Rotation
WINGSOL Stainless Steel Water Filter for Sink Faucet, NSF/ANSI 42&53, 360° Rotating Tap Purifier Reduce PFAS, Lead, Chlorine & Microplastics, 350 Gallons Long-Lasting Reinforced Housing Built-to-Last
NSF 42 and 53 certified
350-gallon capacity
3mm stainless steel
Pros
- Durable 3mm stainless steel housing
- NSF certified PFAS lead chlorine reduction
- 360-degree rotating design
- 350-gallon capacity
Cons
- Adapter fitting can be tricky for non-standard faucets
- Water pressure drops through filter
- Replacement filters cost more
The WINGSOL WS-FM001-PAC rounds out our list as the most rugged option. The 3mm-thick 304 stainless steel housing is noticeably heftier than plastic filters, and it feels like it will outlast every other unit on this page. After three months of daily use, the brushed steel finish still looked new, with no scratches or scuffs.
Filtration is where WINGSOL earns its place. It carries NSF/ANSI 42 certification for chlorine and NSF/ANSI 53 certification for lead and heavy metals. The brand also publishes third-party lab testing for PFAS, PFOA, and PFOS reduction. Across 2,335 reviews, the average rating is 4.4 stars, putting it in the top tier for customer satisfaction.
The 360-degree rotating spout is a thoughtful design touch. You can swing the filter head out of the way when filling tall pots without un-mounting the entire unit. The 350-gallon / 3-month capacity sits between the standard 100-gallon faucet filters and the long-life CuZn under-sink. Flow rate is roughly 0.5 gpm, with the brand claiming a 6-second cup fill.
There are two real considerations. The included adapter set is broad, but if you have an unusual recessed or square aerator, expect some trial-and-error during install. Second, the stainless housing transfers a bit of heat, so be careful if your tap can deliver very hot water. For buyers wanting the most durable NSF-certified faucet water filter for PFAS and lead reduction, WINGSOL is the best stainless steel option.
Hard water considerations
Like most faucet filters, WINGSOL does not reduce TDS, so hard water spots will still form on glassware. Pair the filter with a separate water softener or use a finishing rinse for spot-free results. See our chemical-free filter guide for context.
Replacement filter cost
WINGSOL replacement cartridges run about $28 each, more than PUR or Brita but in line with the 350-gallon capacity. The annualized cost for a typical family lands around $112, comparable to the brand’s plastic competitors.
Buying Guide: How to Choose the Best Water Filter for Your Faucet
Choosing the best faucet water filter comes down to three big questions: what contaminants matter most in your water, what faucet style you have, and whether you can do a quick install or want something permanent. Below we walk through each decision so you can match the right filter to your home without overpaying for certifications you do not need.
NSF/ANSI 42 vs 53 vs 401 – which certifications matter
NSF/ANSI 42 covers aesthetic contaminants like chlorine, taste, and odor. If you only care about better-tasting water and chlorine reduction, this is the minimum to look for. NSF/ANSI 53 covers health-related contaminants including lead, mercury, and cryptosporidium. This is the standard that matters for older homes with potential lead plumbing. NSF/ANSI 401 covers emerging contaminants including pharmaceuticals and pesticides, which is rarer on faucet filters but valuable for well water users.
For most people, NSF/ANSI 42 plus 53 is the sweet spot. The PUR Plus, Waterdrop CTF-01, and WINGSOL carry both certifications. The CuZn UC-200 carries 42 plus documented PFAS testing, and Waterdrop FC-01 carries 42 plus material safety (NSF 372). For a deeper dive into certifications and what they actually mean for tap water quality, check the full faucet filter roundup.
Faucet compatibility and pull-down sprayers
Almost every faucet-mount filter on the market has a known limitation: it does not fit pull-out or pull-down sprayer faucets out of the box. This is the #1 pain point we see discussed on Reddit’s r/WaterFilters and r/Home. If your kitchen has a pull-down sprayer, you have three workable options: buy a brand-specific adapter, switch to a countertop unit like the Waterdrop CTF-01, or move to an under-sink filter like the CuZn UC-200.
Standard round external aerators are the easy case. Most filters ship with adapters that cover roughly 90% of these. Recessed, square, or sensor-activated faucets are the hard cases. Measure the outer diameter of your aerator and check the filter’s compatibility chart before ordering.
Filter lifespan, annual cost, and replacement cadence
Standard faucet-mount filters last 100 gallons or roughly three months in a typical household. Brita stretches that to four months per 100 gallons. The Waterdrop FC-01 hits 320 gallons, and the Waterdrop CTF-01 countertop unit hits 8,000 gallons for a full year. The CuZn UC-200 under-sink filter runs five years per cartridge.
Annual replacement cost is where the real value question lives. PUR and Brita replacement cartridges run $18 to $25 per refill and roughly $80 to $120 per year for active households. The CuZn UC-200 averages $24 per year amortized over five years. If you drink four liters of filtered water daily, that single line item often justifies a more expensive filter. For an environmental perspective, fewer cartridges also mean less plastic waste.
Activated carbon versus reverse osmosis
Activated carbon is the dominant media in faucet-mount filters. It adsorbs chlorine, volatile organic compounds, and many taste/odor issues, but it does not strip dissolved minerals or TDS. Reverse osmosis uses a semi-permeable membrane plus carbon stages to remove up to 99% of dissolved solids, but it requires a storage tank and either a dedicated faucet line or a countertop unit.
For most kitchen faucet users, activated carbon is the right balance of price, flow rate, and contaminant coverage. Reverse osmosis makes sense if you live in an area with very hard water, high TDS readings, or specific concerns about nitrates or arsenic. The trade-off is flow rate: an RO faucet delivers about 0.05 gpm versus 0.5 to 1.6 gpm for carbon filters.
Renter-friendly installation
Faucet-mount and countertop filters are the only true no-drill, no-plumber options. Both attach to your existing aerator and come off without tools. If you move every year or two, a faucet-mount filter is the right call. If you own your home and want a permanent upgrade, an under-sink filter pays off in lower long-term cost and a cleaner countertop. Our city water filter comparison has more on this for municipal water users.
Frequently Asked Questions
Do faucet water filters actually work?
Yes. NSF-certified faucet water filters like the PUR Plus and WINGSOL reduce 90% to 99% of chlorine, lead, and many other contaminants. They are particularly effective for taste and odor improvement, plus health-related reductions of lead and microplastics when the filter is certified to NSF/ANSI 42 or 53.
What is the healthiest way to filter tap water?
For most households, a faucet-mount or under-sink filter with NSF/ANSI 42 and 53 certification is the healthiest affordable option. Reverse osmosis removes the most contaminants but reduces flow rate. Activated carbon faucets like the PUR Plus and CuZn UC-200 cover the broadest practical mix of chlorine, lead, microplastics, and PFAS while preserving beneficial minerals.
How long do faucet water filters last?
Standard faucet filters last 100 gallons or about three months. Higher-capacity options like the Waterdrop FC-01 reach 320 gallons, and the countertop Waterdrop CTF-01 lasts a full year on 8,000 gallons. The under-sink CuZn UC-200 runs five years per cartridge. Replace sooner if you notice taste changes or reduced flow.
Faucet mount vs under sink water filter – which is better?
Faucet-mount filters install in minutes with no tools, making them ideal for renters and quick setups. Under-sink filters take about 30 minutes to install but last years per cartridge and stay out of sight. Choose faucet mount for flexibility; choose under sink for long-term value.
Which faucet water filter removes the most contaminants?
Reverse osmosis systems remove the most, but among faucet-mount and under-sink carbon filters, the WINGSOL and CuZn UC-200 lead the pack with NSF/ANSI 42 and 53 certifications plus third-party PFAS reduction testing. The PUR Plus reduces 70 chemical and physical substances including lead and microplastics.
Final Verdict: Which Faucet Water Filter Should You Buy in 2026?
If you want the single best faucet water filter for most homes in 2026, the PUR Plus Faucet-Mount remains our editor’s choice. It carries WQA and NSF certifications for lead and 70 other substances, installs in minutes, and consistently earns 4.4 stars across more than 23,000 reviews. For renters or anyone avoiding plumbing, the Waterdrop FC-01 stretches a single cartridge to 320 gallons at the lowest annual cost, while the CuZn UC-200 is the right pick for homeowners planning to stay put for at least three years.
Whatever filter you pick, change cartridges on schedule, check the indicator light monthly, and run a quick taste test every 90 days. A faucet water filter only works when the cartridge is fresh, and a $20 replacement every three months is a small price for cleaner, safer drinking water. Ready to upgrade your kitchen tap?
