Though many home water purification systems can claim to be award-winning, the iSpring WKB32B stands up to its high claims by demonstrating how their filters live up to international standards. In fact, all filter options for this model – both standard and optional – are NSF/ANSI certified.
In addition, this model uniquely features a wide set of optional filters that change and enhance the overall flitration process to target certain contaminants. For example, the iSpring WKB32B offers additional filters (sold separately) that are designed to reduce iron and manganese in water supply, while another option cuts down on the lead.
As an added bonus, this module does not decrease total dissolved solids (TDS) levels in your water, allowing it to leave in healthy minerals while still efficiently removing impurities.
Simply put, it’s hard to pass over an industry standard model that manage to filter out most of the major contaminates found in civil and well water sources while still remaining chiefly affordable to most homeowners. This model’s NSF/ANSI certification stood out to me most, causing it to edge out nearly every other model which lacked such a high profile award. Also, this model’s ability to leave in healthy minerals really surprised me. As a result, I have full confidence that this model will provide nearly the best water filtration experience without breaking the bank.
Reverse osmosis (RO) filters are among the most promising in the whole house water filtering market today. Among the models that implement it, the Woder 10K-Gen3 is one of the best. RO filters allow for microscopic levels of purification, down to levels which cannot be seen, tasted or smelled.
RO filters also tend to last a bit longer than regular carbon or sediment filters. The Woder 10K-Gen3 goes above and beyond this expectation, as its main filter is designed to last three years on a single charge. That’s a remarkable feat that few (if any) other single or multi-stage home filters can offer.
While this model is designed to pull out chromium and other heavy metals, it’s been found to only be partially effective at addressing other kinds of contaminants like dirt and sand. As such, this model performs best when used in conjunction with an extra porous pre-filter.
This Home Master HMF3SDGFEC was built with well water users in mind, providing filters that specifically target common well water contaminants. As a result, this model can really change the consistency, color, and smell of standard well water that enters your home.
While not a water softener by nature, this model can do a lot when it comes to taking the edge off of hard water sources. Contaminants like iron are often the source of this undesirable “hardness,” which this model addresses by implementing specialized iron ions in its filters to attract and capture iron particles in your water source.
My biggest complaint with this filter is its price compared to its capability. While I can rationalize paying more for a whole house water filtration system that can pull out every last contaminate in a single process, I simply cannot endorse paying extra for a model that only rises to the industry standard level of filtration.
Even if your home is hooked up to a city water source, you can be sure that iSpring RCC7 will pull every last drop of undesirable additives out of your water. In particular, this model is unique in its ability to pull out fluoride over the course of its 5-stage water filtration system.
This model is also made and manufactured right here in the USA, a testament to its high-quality performance and long-lasting construction. iSpring offers a 1-year warranty on this model and provides you with lifetime access to their specialized support line in order to ask questions that may arise over the many years you use this system in your home.
Seeing is believing with this model because the first sediment filter features a transparent outer casing. This allows you to see it in action, as well as see the filtered-out debris that remains on the filter rather than traveling to your sinks or showers.
Even though there are a number of 5-stage models on the market today, the iSpring RCC7 takes home the prize because it managed to perform best in head-to-head tests. This model doesn’t just filter, either. It also softens water simultaneously, negating the need for you to install a supplementary water softener alongside this machine. At the end of the day, I couldn’t ignore this model’s “Made in the USA” sticker either. American made products are unbeatable for durability and performance, both of which this model exudes at all times.
Though just a single-stage model, 3M Aqua-Pure Model AP903 packs quite a punch with its purpose-built carbon filter. For those with minimal water contamination needs, this water filtration system is able to perform in order to remove many common contaminates that lead to sour tastes and smells.
This model is also virtually leak-free, thanks to its stainless steel connecting head. This head is designed to be corrosion-free and does not lose adherent qualities after several cartridge changes.
Even besides its outstanding filtering capability, the Express Water 5 Stage is a breeze to install. With a brass feed and “quick connect” adapter, this model will fit into place beneath your sink without an extra hardware store run.
This model is also exceptionally committed to leak detection and mitigation. For example, this model uses a technology-infused cloth pad (placed beneath the system) to detect if water is escaping the main system. If it detects water in this manner, it will auto shut-down the system to prevent the leak from propagating.
As a tradeoff for its exceptional filtering capabilities, this model has a notably low flow rate. This may present a challenge for homes with lots of concurrent water usage.
When compared to other whole house water filtration systems, the Watts WH-LD appears weak and diminutive. But in truth, its capabilities are a perfect fit for those looking to take the edge off their natural water source, in terms of both taste and smell.
This model’s unique property is that the entire cartridge chamber is transparent. That means you can visually inspect 100% of the main filtering medium in order to see your filtering progress and assess if a replacement is needed.
If a replacement is needed, this model takes the hassle out of this process. Rather than requiring you to turn off your water main, this model’s built-in bypass mechanism allows you to install a new cartridge while preserving your home’s water supply.
Simply put, this model’s 1,000,000 gallon per year capacity is unheard of in this market, making it a specification worth repeating. Even in a home with four or more people, this filter will easily be able to provide an optimal water output volume for all home cleaning and hygiene needs.
Unique among its peers, this Aquasana model implements an “up flow” dual tank filtration system. Designed to decrease clogging, this mechanism has the added bonus of decrease how much time water spends in contact with impurity-attracting filter mediums.
Customer service is a big sticking point for this model, however, with few ever finding success in progressing to claim a warranty. For those that have little installation experience, this could be a major drawback.
The CULLIGAN WH-HD200-C is a very interesting whole house water filtration option, not least for its compact form factor that can fit into nearly any below sink space with ease. Every inch of this compact device is durable, too, as it is made from stainless steel and industry-grade plastics.
This model is designed with a “install where you need it” modular mentality. So, rather than using a central filtration hub, users are implored to install one of these devices on each pertinent device. While this allows more versatility, it can also run up costs for a full house installation.
When you’re working on a budget, you never want to compromise worthwhile performance. This model doesn’t force you to do so, providing a consistent level of performance and accessibility that other “value” models fall short on. While some other models include a transparent body, for example, only this model manages to keep this transparent cartridge container durable for the long-term. Also, this model can really save you money if you already use Culligan products. This model is compatible with all of their products, allowing you to better budget within your means.
Unlike some other iSpring offerings, this model preserves a compact filter that most 3-stage+ models simply cannot offer. For this reason, apartment and tiny home owners will really appreciate this model’s combination of size and performance.
The iSpring WGB22B is also broadly compatible with other iSpring filters. Known for their “Big Blue” architecture and style, these cartridges are among the industry’s best and easiest to acquire.
Because this model is a “point-of-entry”, it serves a whole home at once, rather than relying on modular components attached to each faucet across the home. This can make for easier maintenance long-term, as well as lower costs due to fewer filter purchases.
The iSpring WSP-50 is small – smaller than any other water filtration system, to be exact. Even in such a compact space, this model doesn’t short change you when it comes to pulling out unpleasant impurities.
This model is not, on its own, a whole house water filter in the traditional sense. Instead, this is a crucial component that can enhance nearly any water filtration system. These types of systems are often clogged up with large sized contaminates like dirt and sand. This add-on is designed to pull those out before they ever make it to the main system proper.
Moreover, this mechanism is unique because it shields your more expensive filtering media from undue harm. With proper installation, this model can make the rest of your whole house water filtration system last longer by several degrees.
Even among other 5-stage water filtration systems, the PureDrop RTW5 stands out for its 3 gallon storage tank that ensures you always have some purified water ready when you need it most. The same goes with the filter system – you’ll always have a replacement ready because this system comes with a set of complementary replacements.
Also, this model is completely lead-free, ensuring that no impurities sneak back into your water after filtration. By the same token, this model is also BPA free, ensuring plastic-born microcontaminants don’t seep into your purification system over time.
Finally, this model is a great purchase for those with minimal plumbing experience. The easy-to-follow instruction guide will help simplify the installation process exponentially.
Don’t see what you’re looking for, or still have questions left unanswered?
Water is essential to life, and a pure, clean water source is essential to life at home. When it comes to improving your health and bodily function, you will almost certainly benefit from installing a whole house water filtration system. One of the best models available today is the iSpring WGB32B 3-Stage Whole House Water Filtration System, but that’s just the tip of the iceberg.
There’s so much to know about the specifications and equipment used in whole home water filtration systems. But I’ve researched all of that information so that you don’t have to! My goal is to make your water filtration shopping experience as easy as possible simply because I know how good it feels to have an expert on your side.
This article has a lot to offer you, from a Buyer’s Guide to a top 12 list of the best whole house water filtration systems. Read on and you, too, can learn all there is to know about these home-life changing water filtration systems.
When making an upgrade to a crucial in-home system like your water supply, you should pause for a moment and consider whether or not the upgrade is truly necessary. For example, many municipal water users are quick to jump on the in-home filtration trend simply to remove a non-specific “unsafe taste” from their water.
While many municipal water sources carry some trace taste (compared to bottled water), you can generally rest assured that this water is safe and treated only with additives that are potable.
However, not all municipal water systems are built alike, especially in cities and rural areas where upgrades to piping infrastructure haven’t been made in several decades. The same can be said of homes that source well water, which nearly always carries some degree of distasteful smell and metallic taste. Among other situations, these are households that can make the best use of a whole house water filtration system.
While evaluating your home’s need for such a water system, you should definitely undergo a water source test in order to make a fact-based conclusion. These tests can be found at most hardware stores and tap only a small sample of tap water to complete.
When you receive your water test results, you may notice several common factors about the water, both visually and chemically. If any of these factors are above acceptable levels, you may be a good candidate for home water filtration installation.
Chlorine is one of the most common elements found in sampled municipal water. Used for many decades as a disinfectant, chlorine generally dissolves over the municipality’s large water volume, leaving little to no ill effects or taste. However, some municipalities over-chlorinate their water, which may necessitate the addition of a filter system in your home.
Unusual tastes or smells are also a common result of even non-scientific water tests. Though nearly all municipal water carries a noticeably different taste than “purified” bottled water, such a taste isn’t always a sign of dangerous impurities. Instead, you should take action towards installing a filter if the unusual taste or smell would otherwise prevent you or a family member from enjoying your tap or shower on a day-to-day basis. A water filtration system can help you achieve great tasting water.
Bacterial contamination is rare, but serious if detected by a test. If you detect bacteria in your water (through a specialized test), you are definitely on firm ground for installing a water filtration system (ideally with a UV light component). Also, if you are hooked up to a municipal water source, be sure to report the bacteria’s presence to the public works department.
Unknown visible particles can leave a glass of water looking cloudy upon the first inspection. Though this can be caused by air bubbles that settle out after a few minutes, some well water sources contain diffused amounts of trace elements like iron, sulfur, and more. These elements can build up over time if you drink a lot of tap water, not to mention leave stains in showers and sinks. In these instances, a home water filter is well justified.
If you’re in a hurry to find your new whole home filtration system, keep these quick tips in mind as you shop from the leading models listed below. For more details and specification descriptions, read our “Buyer’s Guide.”
Before you jump in and buy the first whole house water filtration system you see, be sure that you are knowledgeable in the language and trade terms used to quantify each model’s performance.
For the most part, you should expect to see many of these terms on a filter system’s packaging or online listing. Knowing what each term means in context will empower you to make better decisions regarding your tap water’s taste and total water supply.
Here’s what you should consider before committing to a whole house filter system:
Just like any other long-term home installation, you can love every aspect of a model and still be out of luck if it is too big to fit into your allotted space. To this extent, dimensions play an important role in determining which models can and cannot be feasibly installed in your home.
In order to save yourself time, start by comparing each model based on its dimensions. If you find any that are simply too bulky for your allotted space, then you can immediately remove them from your consideration list.
Like the dimensions, weight can play an often overlooked role in choosing a new water filtration system. While weight itself does not usually inhibit a given model’s ability to take in, filter, and output water, weight can make a significant difference in how quickly and efficiently you install the appliance.
If you anticipate that your chosen water filter in will be heavier than you can handle alone, you should plan ahead and find a friend to help you complete the installation process. Better yet, call a local plumber who has both the strength and the skills to install your new water filter system without trouble.
Capacity refers to the amount of water a given filtration system is rated to handle over a pre-determined period of time. Though the precise volume is generally a quantitative estimate, a water filter shopper can use this figure to qualitatively estimate how capable a given filter is of providing optimal water levels to all necessary appliances (sinks, showers, washers, etc).
Capacity is nearly always measured in gallons, though some European-made models will use liters, instead. These gallon-based estimates can be applied to several common time periods, including gallons per day and gallons per year.
Capacity measurements can additionally give you a firm understanding of what each model considers to be a “normal” amount of use (for long-term optimization purposes). Using a water filter beyond its capacity tends to use up the filters’ effective life much faster than expected.
Filter type refers to the type of material used as a filtering medium within the various stages of the full house water filtration system. Different filter types are designed to draw out different kinds of contaminants, so a diversified arsenal of filters can go a long towards attaining the purest possible water.
No one filter type can do it all, so many major water filter manufacturers have continued to push filtration innovation through the creation of new water filter types. These are some of the most common types you’ll find in whole house filtration systems:
Activated Carbon filters (sometimes referred to as “carbon filters”, “charcoal filters”, or “carbon blocks”) are one of the most common filters types, owing to their ability to pull out common contaminants found in well water. Activated carbon filters are exceedingly good at pulling out undesirable odors and rust particles, leaving your tap water better tasting overall.
Activated carbon is used for this kind of water purification due to its naturally porous molecular structure, which traps contaminates without absorbing water. Often, activated carbon filters are not implemented alone. Because it only filters out considerably large particles, you will likely need a water filtration system that also uses a small particle filter type.
Granular activated carbon (GAC) is a specialized subset of activated carbon filters made from coconut shells. Though they often accomplish the same tasks as a regular activated carbon filter, they are often placed at the end of a water filtering regimen to give one final water treatment to residual chlorine and dirt particles.
Polypropylene is sometimes used as a specialize “pre-filter,” due to its ability to draw out contaminates often left behind by other filtering mediums. In particular, this type of filter is used to block dirt particles from traveling deep into the filtering system and causing congestion in filters with smaller pores. Using their multiple membranes, these filters also sometimes block chlorine and chloramines from filtering into the rest of the system.
Reverse Osmosis filters can tackle a wide variety of microscopic water contaminates due to their implementation of a reverse osmosis (RO) membrane. These membranes work at the molecular level to trap particles ionically bonded onto water molecules. Because of this attention to microscopic detail, this filter type is capable of blocking fluoride, chromium, arsenic, nitrates, copper, radium, salt, and more from reaching your home water supply.
While this filter type has become very popular, it requires a great deal of water pressure to function correctly. As such, water filtration systems that use this type of filter usually show marked decrease in output and water pressure to key fixtures like sinks and showers.
Sediment filters (sometimes abbreviated “SED”) are a broad collection of filtering mediums used filter out “large” water contaminants like sand, rust, silt, and more. These are one of the most common filter types, seeing implementation in many one and two-stage water filtration systems.
Ultraviolet filters (UV filters, for short) are often implemented as a final step in a whole house water filtration system. Unlike other filter types which physically “catch and hold” undesirable contaminants, a UV filter uses condensed beams of UV light to burn away microscopic organic matter. This includes germs, viruses, and other harmful microorganisms that can sometimes thrive in old pipes.
The ultimate effect of a UV filter is that it makes water sanitary, while other filters simply make potable water cleaner and softer by particle content manipulation. Used in conjunction with these other types of filters, a UV filter can really land the killing blow against microscopic debris that may harm those with weak immune systems.
When talking about whole house water filtration systems, a stage is simply one of the filtering media through which water passes before reaching your tap, purified and sanitized. Stages may also be thought of as steps through which your sourced water passes before it reaches superior purity at your tap.
In modern filter systems, stages are often implemented as interchangeable cartridges (not unlike those used in printers). These cartridges are generally cylindrical in shape and sealed (save for a hookup point) in order to prevent water from leaking out during the high-pressure purification process.
Every so often, you will need to replace a stage’s cartridge in order to keep your water filtration system running optimally. Depending on the stage’s filtering medium, this is generally because the filtering medium has become jammed with filtered-out debris and needs to be refreshed before the system will return to peak function.
Many whole house water filtration systems will list off what sediments and microscopic particles they are capable of filtering out of standard well water. Often, this list of sediments is determined by the types of filters implemented in a given filtering regimen, as well as how many stages are in the system overall. These sediments can range anywhere from relatively “large” dirt particles to microscopic viruses.
In all plumbing contexts, flow rate refers to how fast water can pass through a plumbed system and arrive at an output source (such as a sink tap, shower, etc.). When it comes to water filtration systems, the flow rate can measure how quickly the filtration system can take in, clean, and output a gallon of water.
Flow rate can be affected by a variety of factors, each of which can come into play for a water filter. First and most obvious, wide pipes with minimal build-up can create a greater flow rate. In the same vein, using few water fixtures at once can improve flow rate due to a decrease in concurrent demand.
“Fitting size” simply refers to the size of the water hook up that comes built into a given water filter system’s input and output piping. While these fittings can adapt to fit most needs, it is in your best interest to purchase a model that is compatible with your existing infrastructure. Otherwise, leaks and depressurization may occur over time.
