1. Filtrete Advanced 3US-PS01 (Single-Stage)

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (2)

Looking for an incredibly easy-to-install, cheap, andeffective under sink water filtration system? Your journey ends with theFiltrete Advanced 3US-PS01. The filter is NSF-certified to Standards 42 and 53.

These standards indicate that NSF has tested this unit and found it to be great at adsorption. It uses the 0.5 micron 3US-pf01filter cartridge. It’ll remove every contaminant larger than 0.5 microns. The Filtrete Advanced effectively eradicates chlorine, bad taste, and odors. It also helps eliminate rust, silt, sand, and sediment. In addition, it reduces microbial cysts.

It looks uncomplicated, and it is. The install shouldn’ttake you more than 30 minutes. It comes with push-fitting connections so you’lltake very little time on the job.

Its operating pressure is 25 – 125 PSI and the flow rate goesup to 2.25 gallons per minute. It’s a simple under counter system, meaning youdon’t need to install an extra faucet.

Filter replacement should happen after every 2,000 gallonsof water or 6 months, whichever comes earlier. ‘

Pros

  • Insanely affordable
  • Very easy to install
  • Removes smell and bad taste
  • Eliminates up to 97% of chlorine
  • No extra faucet
  • High flow rate
  • Popular with users

Cons

  • Frequent filter replacement

2. Woder 10K-Gen3

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (3)

The Woder 10K-Gen3 works best with municipal water. It’s not the best under sink water filter for well water. Also, don’t use it to treat salt water. That means don’t expose it to softened water. Its NSF 42-approved materials bear the respected ANSI accreditation. It’ll do what the ad says it will.

It’s easy to install. It features two “directconnect” hoses designed to fit 3/8″ under-the-kitchen-sink orbathroom water valves. The unit’s flow rate is 2 Gallons Per Minute at a pressure of 65 PSI. The filters can last up to 36 months assuming normal use. Thatequates to roughly 10,000 gallons of clean water over the period. These filtersoffer up to 6 times more filter lifethan comparable options.

Through selective filtration, the Woder 10K-Gen3 eliminates 99.99% of various contaminants. The good thing is healthy minerals remain untouched. It removes lead, mercury, chromium, and other heavy metals. It also takes care of chlorine and VOCs. In addition, it eradicates odors and bad taste while reducing turbidity (cloudiness).

It compares closely to its sibling the Woder 10K-DC. Unlike its sibling, the Wonder 10K-Gen3 doesn’t use a replaceable cartridge. Instead, it boasts a smart head that carries an in-built value. That makes it possible to replace the cartridge only rather than the whole system as is the case with the Wonder 10K-DC.

Pros

  • Removes over 99.9% of contaminants
  • Eradicates smells and bad taste
  • Cheap
  • Easy install
  • Compact design
  • Long-lasting filters
  • Removes heavy metals and chlorine
  • Doesn’t eject healthy minerals
  • Great ratings on Amazon

Cons

  • Won’t remove TDS
  • Isn’t good for hard well water
  • Coldwater flow rate may drop slightly

The pressure dropis no big deal. And it never affects the hot water supply.

Warranty: 2-yearlimited warranty

3. CuZn UC-200

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (4)

This US-made 3-stage carbon water filter delivers makes municipalwater smell and taste amazing. It removes both organic and inorganic pollutantsincluding mercury, lead, chlorine, and agricultural chemicals.

Also, the unit leaves two healthy minerals namely calciumand magnesium intact. But while these minerals help better health, they won’tdo much good to your coffee making machine. Unfortunately, the unit doesn’teliminate fluoride.

The components are NSF-certified to Standard 42/62. Its flowrate is 2 GPM, and you can expect 50,000 gallons of clean water beforereplacement. That translates to about 5 years of use. However, I don’t quitelike the fact that one must replace thewhole unit.

It offers 3/8″ fittings which work well with most standardplumbing. Have non-standard plumbing? No worries. Request the manufacturer tosend you (for free) an installation kit that makes the install easy and quick.

Pros

  • Removes odors
  • US-made
  • Helps resolve bad taste
  • Eliminates heavy metals
  • Eradicates agricultural chemicals
  • Very easy to install
  • Almostzero maintenance
  • Great reviews from users
  • No extra faucet
  • Cheap

Cons

  • Doesn’t soften water
  • Doesn’t remove fluoride
  • Upon hitting max capacity, the entire unit needs replacement
  • Not good for well water
  • Leaking not uncommon
  • TDS not removed

Warranty

It’s a 5-year warranty. You also get a 90-day money-backguarantee. Don’t like the product? Easy — send it back.

4. APEC WFS-1000

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (5)

Designed and assembled in the U.S., this 3-stage filtereliminates chlorine, smells, bad taste, dust particles, and VOCs. For heavymetals and fluoride, you should replace one of the carbon filters with onethat’ll do the job.

The APEC WFS-1000 features ¼” food-grade tubing foreasy connection. There’s also an adapter that redirects the cold water supplyto this under counter water filtration system.

The filters used in the second and third stages do pretty much the same job. That means you can replace either of them with a filter that removes fluoride and heavy metals. With the APEC WFS-1000 3-Stage, healthy minerals remain in the water. And that’s good for your health.

Since the unit requires you to install an extra faucet, you mayneed some basic plumbing skills. Unfortunately, the manufacturer’s instructionsaren’t the clearest I’ve seen. That said, the install isn’t anything you can’thandle after watching a video or two online.

Filter replacement is easy, too. The filters last up to 12months. And replacing them is inexpensive.

Pros

  • Relatively easy to install
  • US-made
  • Removes odors
  • Takes care of bad taste
  • Eliminates chlorine
  • 12-month satisfaction guarantee
  • Long-lasting filters

Cons

Warranty

Two-year warranty

6. Doulton W9330958 (Single-stage)

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (7)

The Doulton W9330958 is a cute under counter in-line waterfilter that comes with 3/8″ push-fit connectors. It’s a minimal and slimdesign that fits perfectly under the sink. Its flow rate may go up to 1GPM.

Honestly, installing this unit may not be as easy as themanufacturer may have you believe. Some consumers online have complained of receivingan incomplete system – missing parts and all that. Fortunately, they’ll usuallysend the missing parts upon request.

Pros

  • Removes 99.99% cyst and bacteria
  • Solid, durable housing
  • High-quality ceramic filters
  • Removes odors

Warranty: 1-yearlimited

7. Aquasana AQ-5300 3-Stage Max Flow

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (8)

Looking for a “hardworking,” high-capacity, smart(Bluetooth tech) yet affordable under the counter filter? Aquasana’s got youcovered. The entire system comes certified to 3 NSF standards namely 42, 53, and 401. Its engineeringadheres to the requirements of NSFprotocol P473, and the flow rate is 0.72 GPM.

Using its unique Claryum Filtration Technology, it removes up to 99% of at least 77 contaminants. It’s a 3-stage filter that uses a 20-micron prefilter to remove sediment and other relatively large contaminants. There’s also an activated carbon filter that handles pesticides, herbicides, pharmaceuticals, and VOCs. This filter also gets rid of chlorine, removes smells, and improves the taste.

The final filtration stage uses an efficient 0.5-microncatalytic filter to remove chloramine, asbestos, chlorine, and ammonia. Throughion exchange, the filter also reduces heavy metals particularly mercury andlead. To get the most of this great under counter water filter, make sure yourhome’s water pressure is at least 20 PSI.

Pros

  • Leaves healthy minerals in the water
  • Multiple NSF certifications
  • Thorough filtration that eradicates loads of contaminants
  • Removes heavy metals
  • No wastewater
  • Filter replacement easy and fast
  • Easy install

Cons

  • Brushed nickel faucet may get corroded
  • The app may not work seamlessly
  • Won’t remove fluoride
  • Shorter than the average warranty period

Improper washing of brushed nickel often causes corrosion. Oncethe blemishes appear, they’re almost impossible to address. To avoid theproblem, clean your faucet using mild soap and rinse it with warm water.Finally, wipe it off with a soft piece of cloth.

The unit comes enabled with Bluetooth technology. Thefeature is intended to spit out real-time filter life and water consumptiondata. But it’s doubtful the feature works as the manufacturer envisaged.

I mean, the app requires you to input the installation dateand location. Shouldn’t the app know the location and the date? It seems like afeeble attempt to make the system seem smart and modern. It’s modern, though,and this glitch doesn’t make it less effective. I hope this addition doesn’taccount for much of the overall unit price, though.

Warranty

A 6-month limited warranty covering materials and workmanship.

9. ISpring CU-A4 (4-Stage Water Filter)

Best Under Sink Water Filters - Reviews and Buying Guide - Water Filter Judge (10)

This unbelievably affordable 4-stage under counter water filter deserves your attention. It performs thorough filtration work, down to 0.1 microns. That’s ultrafiltration, a kind of filtration that enables you to remove the tiniest particles from your water.

Ultrafiltration works alongside GAC and KDF filtration to remove 99% of a broad spectrum of contamination.

Some users said their water looked like it had an oily sheenafter they’d installed it. The oil serves to seal the cartridges, but some ofit naturally ends up in the water. To remove it, make sure to flush the unitusing roughly 15-20 gallons of water.

Note: You can use your unit as an inline water filter. In that case, you won’t need the included air gap faucet. In this situation, you should install a pressure regulator so the pressure won’t exceed 40 PSI.

Warranty

1-year limited warranty. There’s also a 1-year satisfaction guarantee, something I really liked.

The unit features a built-in shutoff valve that makes filter change very easy. No need to shut off the water at the main supply. Also, it features a “twist-off” cartridge design which makes filter replacement as easy as ABC. In addition, the shutoff meter communicates when to change the filter cartridges — no need to remember anything.

Pros

  • Removes bacteria and protozoan cyst
  • NSF-certified
  • Reduces turbidity
  • Eliminates VOCs and MTBE
  • Gets rid of odors and bad taste

  • Good for both well and city water
  • Cleans entire cold water supply

Cons

The provided adapter seems to be too soft. Also, the adaptercrosses threads quite easily. It’s best not to use the provided adapter valve.Instead, use this one: JG Speedfit ASVPP1LF 3/8″ x 3/8″ x ¼”(Angle Stop Adapter Valve). It works incredibly well. For the price, the unitis a great deal. However, the hardware probably needs a bit of work.

Warranty

10-year limited warranty. If the warranty were the only consideration, the 3M Aquapure would be the best under the sink water filter system.

Overall Winner

The Aquasana wins hands down. The unit comes with three important NSF certifications: 42, 53, and 401. It also fulfills the requirements of the NSF protocol P473.

Under-sink Water Filters Buying Guide

What features should one keep their eyes peeled for? This brief under-sink water filters guide(hopefully) covers that question fully. If you pay attention to the followingaspects, you’ll soon find the best under-sink water filter you can afford.

1. Contaminants Eliminated

Before you buy any type, analyze your water to know whatyou’re dealing with. Different kinds of water filters remove different kinds ofcontaminants. If heavy metals, VOCs, agricultural, and industrial chemicals areyour biggest headache, choose a unit that uses a GAC filter.

If your intention is to eradicate TDS, consider picking anunder-sink RO filter. And if you wish to remove many different kinds ofpollutants, go for a multi-stage under-sink filter.

2. Water Pressure

Choose an under-sink water filter with enough pressure tokeep you supplied with clean water all of the time. But in some situations, toomuch pressure becomes a bad thing. If your water swarms with contaminants, pickan option that doesn’t deliver too much pressure.

If there’s excessive pressure, water spends very little timein the filter. Consequently, some of the contaminants come out with the treatedwater.

Generally, simple under-sink filtration systems deliverbetter pressure than conventional under-sink options. And RO under-sink systemsneed more home water pressure than other options to operate optimally.

Tip: know yourhome’s water pressure before buying a water filter. If the pressure is tooclose to a filter’s lower pressure limit, you’ll probably need a pressurebooster.

3. Faucets

Will you install an extra faucet or use the existing one? With conventional under-sink units, you must install an extra faucet for dispensing treated water. But that’s not the case with simple under-the-sink options.

With these ones, you’ll get clean water from the same faucet that delivers untreated cold water. Many people are beginning to show a preference for simple under-sink water filters.

4. Ease of Installation

RO under-sink water filters may require a higher skill levelto install than other under-sink types. Similarly, conventional under-countertypes typically need more effort to install than simple under-sink options do.

But generally, under-sink filters are relatively easy to install. One may need basic plumbing skills, but pretty much anyone can do the job after reading the manufacturer’s instructions. Or after watching a couple of videos online.

5. Maintenance: Longevity of Cartridge

Pay attention to how often you’ll need to replace filters for your under-sink water filter. Filters cost money. And these small costs can really snowball into a hefty figure over the long term.

With some units, filter replacement happens every 3 to 6 months. While the filters may not cost much, you might start hating the idea of having to buy them forever.

Luckily, some models use filters that last up to 5 years.Such filters last long because they’re made of superior material.Unsurprisingly, they’re more efficient than their counterparts that don’t lastmore than 6 months.

In the final analysis, filter life depends on the overallquality of your water. The higher the level of contamination, the shorter thelifespan of your filters. Keep that in mind when shopping.

6. Design

Be sure the unit you wish to install will fit neatly underyour sink. While under-sink filters feature a compact design, under-the-counterspaces vary in size from home to home. Stay away from bulky options if yourspace is rather small.

7. Price

Price, for the most part, reflects the quality and level of performance you might expect. But it’s not uncommon to come across relatively expensive units that deliver noticeably lower performance than their cheaper counterparts.

Final Thoughts

After reading this post you should be able to narrow your search down to a particular option. Hopefully, you’ll find a recommendation that fits your needs. We have also presented a short buyer’s guide to help make an informed decision.
