2019’s Culligan Water Filtration System Reviews – Pros, Cons & Cost

    Culligan was established in 1936 with its headquarters based in Rosemont, IL. From the start, the company offered home water softening solutions.

    Today, the product range is much wider. It includes water treatment systems – mainly softeners & filters – for private homes, offices and commercial and industrial applications. Another business field is the filtered bottled water delivery service.

    While Culligan has always focused on building a network of franchises with local experts that act as company representatives, the DIY Solutions water filter line is a relatively new addition. And it’s what this Culligan review series is all about.

    We will take a close look at:

    Why Culligan?

    Although we wouldn’t recommend our readers to invest in a Culligan water softening unit mainly due to very bad customer feedback, a filtration system that is part of the DIY Solutions line is a different story.

    Why? Because Culligan refuses to provide any pricing information for their softening systems upfront, not so with the filters. Furthermore, the costs for purchase and maintenance are not only 100 percent transparent for the latter, they are also much lower. Another factor is user friendliness.

    The only drawback that remains is Culligan’s customer service which leaves a lot to be desired. The good news is that this doesn’t matter as much with a product that you can install and service yourself.

    Other reasons to invest in a Culligan DIY Solutions water filtration system are:

    • NSF Certifications – Most models were tested and certified against NSF standards. This guarantees optimal system performance in regards to contaminant reduction. The RFC-BBSA whole house filter, for instance, is certified to reduce 90.3% chlorine taste and odor for 10,000 gallons. The US-EZ-4 under sink premium filter has earned 4 independent NSF certifications (Standard 42, 53, 401 and Protocol P473) for the elimination of dozens of potentially harmful contaminants, among them lead, cysts, perfluorinated chemicals and VOCs. Another example are the FM-15A & FM-25 faucet mount filters that take care of chlorine (97.4%), lead (at least 98%) and turbidity (99.1%).
    • Warranty – All Culligan DIY Solutions systems are covered by limited warranties of varying lengths (between 1 and 5 years).
    • DIY – We have already mentioned the DIY aspect that allows you to install and maintain your Culligan filter yourself to make significant savings. Of course you should be somewhat handy with tools. Other than that it’s learning by doing.
    • Low in Maintenance – The filters are maintenance-free for the most part. All you have to do is change the cartridge(s) every once in a while.
    • Plenty of Feedback – Apart from this website, there’s plenty of customer feedback on Amazon that will help you to learn about all the benefits and drawbacks that a specific product has.

    1. Culligan WH-S200-C & WH-HD200-C Whole Home Sediment Filters

    Best For:

    • City or well water
    • Mainly to remove sediment
    • Small to mid-sized homes (WH-S200-C)
    • Small to large homes (WH-HD200-C)

    In a Nutshell:

    Culligan’s DIY line features a total of five different whole house water filtration systems with a variety of housing styles, capacities and flow rates. The WH-S200-C and WH-HD200-C are the two most popular units.

    The WH-S200-C is a standard duty filter with ¾” ports for small to mid-sized homes, whereas the WH-HD200-C is a heavy duty system with 1-inch ports for a higher flow rate. Thus it’s perfectly suited for larger families with 2 or more bathrooms.

    Both will protect your plumbing and water-using appliances from sediment and scale resulting in an increased lifetime of your water heater, for example, and also guaranteeing peak performance.

    Three additional benefits that we wanted to point out are:

    1. The built-in bypass valve allows you to replace the filter without having to turn off the entire water supply to your house.
    2. You can choose between a number of different cartridges according to your needs. Some are good for trapping sediment, rust, scale, dirt and coarse sand. Others will even remove chlorine – you get the idea. They all have varying filtering capacities.
    3. NSF certifications for lead compliance (Standard 372), material safety and structural integrity (Standard 42, WH-HD200-C), and material safety only (Standard 61, WH-S200-C).

    Culligan WH-HD200-C

    Pros & Cons

    Pros
    • Protect plumbing + appliances from sediment and scale
    • Choose from different cartridges according to your needs
    • NSF Standard 42, 61, 372 certifications
    • Clear housing for timely filter replacements
    • Battery-operated filter life monitor
    • Quick & easy installation
    • Low maintenance cost
    • Built-in bypass valve for fast filter changes
    • 2-year limited warranty

    Cons

    2. Culligan HF-360A, HD-950A & HF-150A Whole House Filtration Systems

    Best For:

    • City or well water
    • Mainly to remove sediment
    • Small to mid-sized homes (HF-360A)
    • Small to large homes (HD-950A)
    • Small to mid-sized homes (HF-150A)

    In a Nutshell:

    The HF-360A, HD-950A and HF-150A are three more whole house filtration systems by Culligan that will remove sediment and scale from all the water entering your home. The goal: Protect your plumbing, washing machine, dishwasher, water heater, etc. from clogging.

    Furthermore, they might trap sand, rust, coarse and silt, and even eliminate chlorine and other tastes & odors. This depends on which filter cartridge you choose to use, though.

    • The HF-360A and HF-150A with a moderate flow rate (¾” ports) are for small to mid-sized homes.
    • The HD-950A with its heavy duty ports (1 inch) is ideal for larger houses, even farms says Culligan.

    Culligan HF-360A

    Pros & Cons

    Pros
    • Protect plumbing + appliances from sediment and scale
    • Choose from different cartridges according to your needs
    • Replacement filters are affordable and widely available
    • NSF certification for chlorine taste and odor reduction (not all)
    • WQA tested and certified for material safety and structural integrity (Standard 42)
    • Clear housing for timely filter replacements
    • Quick & easy installation
    • Low maintenance cost
    • Built-in bypass valve for fast filter changes (HF-360A only)
    • 5-year limited warranty

    Cons
    • HD-950A and HF-150A come without filter cartridge
    • Common issues with leaks
    • Some cartridges have a low flow rate only suited for households with 1-2 people

    3. Culligan Easy-Change US-EZ-1, US-EZ-3 & US-EZ-4 Under Sink Drinking Water Units

    Best For:

    • (Heavily) contaminated tap water
    • Making water ready for drinking
    • Small to larger families

    In a Nutshell:

    The EZ-Change (“Easy-Change”) under sink drinking water filter series features the US-EZ-1, US-EZ-3 and US-EZ-4.

    • The EZ-1 is the most affordable unit and perfect for basic filtration needs a.k.a. better tasting, odor-free water.
    • The EZ-3 is for “advanced” filtration. Apart from chlorine and particulates, it’ll also take care of some of the more harmful impurities that are commonly found in tap water – think cysts and lead.
    • The EZ-4 provides water of the highest purity and is thus the most expensive. Contaminants that the EZ-4 can eliminate include chloramines, MTBE, mercury, chloroform and PFOA & PFOS.

    By the way, all three are NSF certified for guaranteed performance and make us of carbon media. Their filtration capacities vary between 500 and 3,000 gallons.

    What’s more, no matter which system you choose they all come with the same standardized filter head. In other words, if your filtration needs change you can easily switch between cartridges.

    Speaking of filter changes, thanks to the modular design the cartridges can be installed and uninstalled with a simple twist which is a huge time saver.

    Culligan water filtration reviews: Easy-Change US-EZ-4

    Pros & Cons

    Pros
    • Provide great-tasting drinking water
    • NSF Standard 42 certified for chlorine reduction
    • NSF Standard 53 certified (EZ-3 & EZ-4 only)
    • NSF Standard 401 + Protocol P473 certified (EZ-4 only)
    • Standardized filter head allows upgrades/downgrades
    • Modular filter design allows for quick replacements
    • Ready for DIY install thanks to quick connect fittings
    • Come with everything required for setup and operation
    • 2-year warranty (limited)

    Cons
    • Water flow feels a little slow
    • Cheap chrome faucet (mainly plastic)
    • Plastic connectors prone to leaking
    • Incidences with cracked housings
    • Installation might require drilling

    4. Culligan WSH-C125 & HSH-C135 Filtered Shower Heads

    Best For:

    • Chlorinated city water
    • Dry, flaky skin and brittle hair

    In a Nutshell:

    If you are searching for a shower filter, Culligan offers the WSH-C125, a filtered shower head, and the HSH-C135 which is the hand-held version.

    Both work with the same filter cartridge to remove between 55 and 99 percent of free available chlorine from municipal waters – chlorine that would otherwise damage the follicles of your hair and cause dry and itchy skin.

    In addition, sulfur smell and mineral scale will be reduced for a more refreshing shower experience.

    FYI: Obviously you can’t compare the WSH-C125 or HSH-C135 to a genuine water softener system for whole house applications in terms of softening effectiveness.

    Oh, and the filter media is bacteriostatic so that the growth of microorganisms in the filter head is limited. This will make your everyday shower much healthier.

    Culligan WSH-C125 Filtered Shower Head

    Pros & Cons

    Pros
    • Soften hair and skin
    • Reduce sulfur smell + mineral scale for refreshing shower experience
    • Bacteriostatic filter media for a healthier shower
    • Choose between fixed head and hand-held
    • NSF Standard 177 certified for aesthetic water improvement
    • Meet EPA WaterSense program standard for water conservation
    • 5 spray settings for added comfort
    • Install in minutes on any industry standard ½” threaded pipe
    • 5-year limited manufacturer warranty

    Cons
    • Showerhead does not stay up due to design flaw making ergonomic standing difficult (HSH-C135 only)
    • Slightly lower flow rate
    • Low maintenance requirements
    • Reasonably priced replacement cartridges
    • Filters do not last as long as advertised for some users

    5. Culligan FM-15A & FM-25 Faucet Mounted Filters

    Best For:

    • Basic filtration needs
    • Water for drinking and cooking
    • Chlorinated city supplies

    In a Nutshell:

    Next in our Culligan reviews are the FM-15A and FM-25 faucet mount filters that make a simple solution for better tasting and somewhat cleaner drinking water free from odors.

    They apply carbon block filtration to adsorb sediment, turbidity, chlorine taste & odor, lead (≥98%) and other impurities from your water (certified to NSF standards) at a flow rate of .5 gallons per minute. Now, half a gallon of filtered water per minute isn’t bad but not a whole lot either.

    By the way, the only difference between the two is their color. The Culligan FM-15A comes in white, whereas the FM-25 has a “chrome” finish (plastic with chrome coating) that easily blends with other kitchen fixtures.

    Another feature that we wanted to point out is the diverter tab which allows you to easily switch between filtered and unfiltered water whenever you want.

    This will greatly extend filter lifetime as you can use regular tap water for purposes other than cooking and drinking. As a result, maintenance costs are reduced to a minimum.

    How about the installation? Don’t worry, it’s tool-free and only takes a couple of minutes. Plus two adapters are included in the package.

    Culligan FM-25

    Pros & Cons

    Pros
    • Provides better tasting water free from odors
    • Effective lead reduction
    • NSF Standard 42 & 53 certified
    • Easily switch between filtered and unfiltered H2O
    • Tool-free installation
    • 2x faucet adapter included
    • 2-year limited warranty

    Cons
    • White finish looks cheap
    • Issues with leaks
    • Low flow rate
    • Incompatible with pull-down/pull-out faucets
    • Adapters may not fit all (standard) faucets
    • Filter housing can be hard to open making replacements a pain
    • Replacements filters are relatively expensive

    6. Culligan PIT-1 Pitcher Filter

    Best For:

    • Slightly contaminated tap water
    • Making water ready for drinking
    • 1-2 people

    In a Nutshell:

    The PIT-1 is Culligan’s “perfect solution for great-tasting water at an economical price” – at least that’s what the company says. Is there any truth to the strapline?

    First of all, yes, the PIT-1 is indeed very affordable. In fact, it’s cheaper than what you pay for most other pitcher filters. However, we read many reviews where people complained about the “horrible” taste that the PIT-1 added to their water.

    Other than that, the unit is sturdy, very compact and thus fits in most refrigerator doors. The downside is that it can’t hold a lot of water so it’s best suited for 1 to 2 people at max.

    Any NSF certifications? Standard 42 for the aesthetic reduction of chlorine taste and odor (82.8%), zinc (97.4%) and particulate class VI (>99.9%). Also, Standard 53 guarantees the removal of copper (>84.0%) and mercury (>91.0%).

    Culligan water filters review: PIT-1

    Pros & Cons

    Pros
    • Very cheap price
    • NSF Standard 42 + 53 certified
    • Compact (fits most refrigerator doors)
    • Simple replacement indicator reminds you of cartridge changes
    • Spout cover prevents impurities from transferring into the pitcher
    • 2-year warranty (limited)
    • Replacement filters are affordable and widely available

    Cons
    • Water tasted awful for some users with a faint chemical hinge to it
    • For a maximum of 1 to 2 people
    • Fragile top may fall off when pouring and break
    • Upper reservoir must be completely empty for pouring (common issue with pitchers)

    7. Culligan RVF-10 for RVs

    Best For:

    • Recreational vehicles
    • Improving water aesthetics
    • Chlorinated city water

    In a Nutshell:

    Want clean water in your camper? The Culligan RVF-10 might be just what you need.

    It’s a pre-tank filter for RV and marine use that allows you to enjoy better-tasting water (almost) free from foul tastes and odors – think chlorine – as well as sediment.

    Culligan water filters review: RVF-10

    Pros & Cons

    Pros
    • Slim design for easy storing
    • Inexpensive replacement filters
    • Great for home brewing
    • Installation is a piece of cake
    • 5-year limited warranty

    Cons
    • Hose not included
    • Cheap plastic fittings prone to leaking (better change with brass)
    • Low capacity per cartridge

    8. Culligan IC-EZ-1, IC-EZ-3 & IC-EZ-4 for Icemakers + Refrigerators

    Best For:

    • (Heavily) contaminated tap water
    • Making water safe for consumption

    In a Nutshell:

    Culligan’s Easy-Change (EZ-Change) icemaker and refrigerator water filter series uses the exact same filter cartridges as the Culligan under sink drinking water units:

    • The IC-EZ-1 is for basic filtration
    • The IC-EZ-3 for advanced filtration needs
    • And the IC-EZ-4 for premium filtration

    As mentioned above, we are talking about carbon-based filters with a flow rate of .5 gallons per minute which is more than enough for any refrigerator or icemaker.

    Impurities that the different models can remove range from chlorine and larger particulates to cysts, lead, atrazine, lindane, chloramines, MTBE, mercury, chloroform and dozens of VOCs.

    Different NSF certifications speak for the sophistication of the filtration process.

    Again, no matter which version you choose the head is compatible with each of the cartridges which is great for upgrading (or downgrading) your system.

    What’s more, the head features a simple twist on/off mechanism. This allows for quick and easy filter changes (tool-free) without making a water mess.

    Culligan water filtration reviews: IC-EZ-1

    Pros & Cons

    Pros
    • Provide great-tasting drinking water + ice
    • NSF Standard 42 certified for chlorine reduction
    • NSF Standard 53 certified (EZ-3 & EZ-4 only)
    • NSF Standard 401 + Protocol P473 certified (EZ-4 only)
    • Standardized filter head allows upgrades/downgrades
    • Modular filter design allows for quick replacements
    • Come with everything required for setup and operation
    • Easy to install and use
    • 2-year limited warranty

    Cons
    • Inlet/outlet connections prone leaking
