Buying Guide

Now that you’ve seen our whole house water filters reviews and learned a little more about some of the best rated whole house water filters on the market, it’s time to take a closer look at what these filters do, why you might want one, and what sort of features and factors you need to think about when shopping for your next filter too. There are lots of different whole house water filters out there, and it’s vital to take your time and compare your options in order to find a model that suits your needs, fits your home, and is able to provide the clean, clear water you crave.

Why and when do you need a whole house water filter?

In order to understand why you might want to buy the best whole house water filters for home, you need to understand what kinds of substances and contaminants can be found in your water supply. Reports show that the vast majority of tap and well water in the US contains medium to high levels of contamination, caused by both environmental and industrial pollution.

It doesn’t matter where your water is coming from, there’s a high chance that it will contain various chemicals, by-products, and undesirable elements that may harm your body or put your health at risk. Water from surface sources, for instance, can be exposed to acid rains and chemicals in the air, while groundwater wells can be contaminated with chemicals in the surrounding land or pathogens in the area too.

Of course, in most cases, the quantities and concentrations of these contaminants aren’t high enough to cause any immediate harm or illness to the body, but over the long term, with regular consumption, they can cause issues. Examples of undesirable substances and contaminants that might be floating around in your own home’s water supply include:

  • Pathogens – Bacteria, viruses, and parasites can be found in some water supplies, potentially leading to infection and disease
  • Metals – Various harmful or toxic metals like lead and mercury may also be found in the water supply
  • Hard water – Hard water is common across America and contains excessively high amounts of certain minerals like calcium or magnesium, which can damage pipes and be unhealthy when consumed in large quantities.
  • Organic Materials – Certain organic substances like pesticides, volatile organic chemicals (VOCs), and other by-products can also be found in home water supplies

If any of these contaminants are present in your home’s water supply, investing in a whole house water filter could be a great choice. Whole house water filters are designed to remove these impurities from the water as it enters the home, ensuring that all the water that flows from your faucets, showers, and other sources has been fully cleaned and filtered, making it much purer and safer to use and consume each day.

In general, since almost every home across America has some form of contaminants or impurities in their water supply, there’s never a bad time to invest in a whole house water filter. They can be especially important for those living in areas where things like VOCs, heavy metals, and pathogens may be found in the local water supply, and they’re a great choice for people who want to feel more positive and safe regarding the water they use.

Some of the benefits of choosing a whole house water filter include:

  • Whole House Coverage – You might hesitate between buying a whole house water filter or a smaller filter unit that can be attached to your kitchen sink. While smaller, individual filter units may be cheaper in some situations, they can only work on one sink or faucet, meaning that all the other water sources around your home won’t be filtered. A whole house water filter, like the 3M Aqua-Pure AP903, offers filtration for the whole house, so you don’t have to worry about any dirty or contaminated water in any room.
  • Clean Water – Naturally, one of the most obvious and important benefits of opting for a whole house water filter like the Home Master Whole House Three Stage Water Filtration System is the fact that it will provide you with cleaner and safer water. This is especially important for those who drink water from their faucets each day, as it will be free of 99% of impurities, making it much healthier and even tastier too.
  • Better Showers And Baths – It’s not just the water from your kitchen faucet that will be improved with a whole house water filter system; these filters will also clean up the water that flows out of your showers and baths too, and you can really feel the difference when it comes to washing your body and hair with clean, clear water, as opposed to water that is filled with contaminants. Having a water filter can therefore help to improve skin and hair health too.
  • Money-Saving – Having a whole house water filter like the 3M Aqua-Pure AP903 can even save you money in the long term, despite the initial installation costs. How? Well, since the water filter will be cleaning your water supply of impurities and softening hard water too, there will be less chance of scale and corrosion occurring in your pipes and appliances. This will actually help you pipes stay stronger for longer and your appliances last longer too, without needing to be repaired or replaced.

8 Best Whole House Water Filters - Household's Water Supply without Contaminants

Features to consider when choosing a whole house water filter

Before buying a whole house water filter to improve water quality in your home, it’s wise to think about some key features in order to find the right model to suit your needs. These filters can come in various types, from whole house chlorine water filters to whole house iron water filters, and even filters for well water too, so it’s unwise to simply dive right in and buy the first model you find, as others might be a better match for your home. Read on to learn about the key features of whole house water filters and discover the right option for you.

Filter capacity

One of the first things to think about when choosing the best water filters whole house for you is filter capacity. This tells you how much water (measured in gallons) the filter can handle, before the filter media starts to lose effectiveness and needs to be changed. For example, a water filter with a capacity of 100,000 gallons, like the iSpring WGB32B and Aquasana EQ-1000-AST, should be able to filter 100,000 gallons of water before needing to have new filter media installed.

You can also think of filter capacity as being equivalent to the “estimated lifespan” of your whole house water filter. Even though the filter will continue to work once it passes this limit, it won’t be as effective, which is why it’s so important to look at filter capacity when choosing a filter system to buy. Some units are able to boast of much higher filter capacities than others, making them better suited for homes that have higher than average amounts of water usage each day.

Statistics show that, on average, an American will use between 80 and 100 gallons of water on a daily basis, taking into account things like doing the dishes, taking showers, and flushing toilets too. You can reduce the amount of water you use through various conservation methods, and some homes will lose less water than others due to having fewer people or fewer bathrooms too, so it’s wise to think about your situation and typical water consumption in order to find a filter that works for you.

Those living in large homes with multiple bathrooms and big families will usually be using a lot more water on a daily or yearly basis than someone living on their own in a small apartment, so it makes sense that the family should look for a water filter system with a very high capacity, while the apartment dweller doesn’t need to worry too much about capacity. High capacity filters are often more expensive initially, but can be cheaper to run as you won’t need to replace the filters as often.

Number of stages

Another key factor to consider when looking for the best whole house filters for well water or tap water is the number of stages. However, it’s important to not let this particular factor mislead you. Some people automatically assume that models with more stages are superior and offer deeper, more thorough filtration of the water supply, but this isn’t always the case.

In simple terms, the number of stages tell you how many forms of filtration a filter system is capable of, and the filtration process can be broken down into different stages. The sediment filtration stage, for instance, is focused on removing dust and dirt from the water, while the carbon filtration stage focuses on removing bad tastes, unpleasant odors, and certain chemicals and elements from the water.

The most important stage of filtration in a typical whole house water filter system is reverse osmosis, which helps to remove up to 99% of all impurities in the water, including heavy metals. As long as your system is capable of removing these impurities and cleaning up the water efficiently, the exact number of stages isn’t overly important. The EcoPure EPWHE, for instance, only has one stage, but is able to remove sand, dirt, chlorine, sediment, and more.

The Express Water Whole House Water Filter, meanwhile, offers three stages of filtration, able to remove dirt, chlorine, organic materials, VOCs, and rust, which shows that, in general, more stages of filtration isn’t always necessary, but can still be a great benefit and often results in even more undesirable substances and contaminants being taken out of the water.

If you live in a location where your water might be at risk of many different types of contaminants, having those extra stages could be better for you, but if your water is already reasonably clean, you may be better off opting for a simpler and better value option with just one stage of filtration.

GPM

GPM is another important feature to think about when looking for filters, whether you’re Lowes whole house water filters or filters from other brands, stores, or sites. GPM stands for gallons per minute and basically tells you how efficiently the filter can operate. This factor shows how much water can be filtered per minute. For example, the Aquasana EQ-1000-AST has a GPM of 7, meaning it can filter 7 gallons of water per minute.

GPM can vary quite a lot from one whole house water filter system to the next, with some being able to filter much greater quantities of water than others. The Home Master Whole House Three Stage Water Filtration System, for instance, has quite a high GPM rating of 15, making it well-suited for homes where lots of water is being used on a daily basis, especially if multiple sources of water are being used at the same time, i.e. two people taking showers and one person running a faucet in the kitchen.

Again, it’s important to think about your own personal situation when evaluating how much GPM you need from your whole house well water filters. If you live with a large family, in which lots of people are using water at the same time each day, you’ll need a high GPM filter system to cope with the demand. If, however, you live alone or as a couple, with low to medium water usage, you won’t need to worry so much about getting a high GPM filter.

Replacement

Every so often, you’ll need to perform some essential maintenance on your whole house water filter system. The most important part of this maintenance is replacing the filter. The filter media can’t run for years and years at the same high efficiency rating, and as time goes by, it will begin to degrade, becoming less effective and eventually needing to be replaced.

The ‘Replacement’ factor for each whole house water filter tells you how often you’ll need to think about replacing the filters. For example, for the Culligan WH-HD200-C, it’s recommended to change the filters every six months to ensure that the system continues running smoothly and carrying out its intended functions.

There are other filter systems out there that may have longer or shorter replacement times. Some can be left a year or more without any need for replacements, while others might need to have the filter media replaced every few months.

It’s also important to note that the replacement times are only an estimate, and the exact timings may vary, depending on how much you use your filter system. For example, a busy home with heavy water usage will wear out the filters faster than someone living on their own and doing their best to save as much water as possible.

In general, looking for the longest replacement times can be a great way to find a cost-effective whole house water filter that you won’t need to worry about too much. The longer the times, the less often you’ll need to buy new filters and fit them into the unit. The Aquasana EQ-1000-AST is one of the best models for this category, boasting 10 year replacement times.

Warranty

When buying any kind of device or appliance, including a whole house water filter system, you need to think about the warranty too. Even though the best filters are made to last and should serve you well for years to come, there’s always a chance that something could go wrong as time goes by and a part of the system might break down or cease to function as well as it once did, through no fault of your own.

If and when this happens, it’s good to know that the manufacturer has your back and will be willing to pay out for any repairs or replacements that might be needed, rather than you having to handle those costs on your own. This is why many of the best water filter brands offer strong, long warranty policies on their units, and a long policy also proves that the manufacturer has confidence in their product as well, which is always a good sign.

When it comes to warranties, the longer the better, but the lengths can vary from one brand to the next. The Aquasana EQ-1000-AST, for example, comes with one of the best warranties around, offering 10 whole years of coverage, but some other models will come with much shorter warranties of just a single year. So, if you’re worried about the possibility of your unit suffering a fault or failure and want to be covered, focus on finding a filter with a long warranty.

8 Best Whole House Water Filters - Household's Water Supply without Contaminants

When buying almost anything in life, you have to think about the price and set out a budget that works for you. Some people shy away from the idea of buying whole house reverse osmosis water filters as they worry about the cost, but the truth is that it’s perfectly possible to find efficient, effective filter systems at very fair, reasonable prices. Plus, having a filter could protect your health and save you money in the long run by providing you with cleaner, fresher water.

Whole house water filters can be found with a wide range of price tags. There are very budget-friendly models out there, like the DuPont WFPF13003B, as well as more expensive offerings. The more pricey models tend to have additional stages of filtration, higher capacities, or other unique features that justify the additional cost, but sometimes, the more affordable option offers everything you need.

This is why it’s important to think about your specific situation when shopping for a whole house water filter and try to choose a model that matches your needs. If you live in a small place, don’t use much water, and have relatively clean water in general, a simple, affordable filter will be fine for you. If you use lots of water and need very thorough filtration for VOCs and metals, it’s worth it to choose a more expensive model in order to get the performance you need.

Other features

There are also several other features to think about when buying a whole house water filter. As well as the essentials, like warranty, price, and filtration stages, some models may boast a few little extras that help to make them even more appealing or better-suited for your home and situation. It’s worth taking a look at these extras; they may not seem too important at first, but could help to make your filter much easier to set-up, more effective in action, or more long-lasting.

The Express Water Whole House Water Filter, for example, has the option of being installed in a mounted or unmounted position, which helps to make it highly versatile at the moment of set-up, giving you a few different ways to install it to suit your needs and save space at your home. It also comes with lifetime customer support, provided by the manufacturer, so you’ll be able to get in touch with them and ask for any help or guidance when it comes to using or fixing the filter.

It’s also worth taking a look to see if your chosen whole house water filter has been certified by any important bodies or authorities. The Culligan WH-HD200-C and EcoPure EPWHE, for example, come with special certification to prove their safety and efficiency. Look out for NSF, ANSI, and CSA certification as marks of quality when it comes to whole house water filters. If a unit is able to meet these standards, it should be one that you can trust.

Then, there are models like the 3M Aqua-Pure AP903, which are able to work with both chlorinated (municipal) and non-chlorinated (well water) systems, making them more versatile for installation in different kinds of home, and if you do have a well water system at your house, you need to make sure you find a model that is fully compatible with this kind of water, while those on municipal supplies need to find a unit that can get rid of chlorine in order to enjoy the best-smelling and tasting water.

Whole house water filters – installation and maintenance tips

8 Best Whole House Water Filters - Household's Water Supply without Contaminants

After purchasing a whole house water filter, the first thing to do is think about installing it. The exact instructions for installing a whole house water filter will vary greatly from one model to the next, so it’s wise to consult the instruction manual or even contact the manufacturer’s customer support, if possible, in order to learn more about how and where you’re supposed to set the system up.

If you have some DIY experience or knowledge, you should be able to set up the system yourself with relative ease. However, if you don’t know much about piping or water filters and are unsure at any stage during the installation process, you may want to call in a professional. A plumber or handyman should be able to set up a whole house water filter for you quite quickly for a reasonable fee. If you choose to go it alone, be sure you have the right tools to hand, such as a wrench, screwdriver, drill, pipe cutter, mounting brackets, tubings, fittings, and Teflon tape.

Installation of a whole house water filter doesn’t need to be difficult to take too long. It’s perfectly possible to have the whole system up and running in a few hours, without too many issues, as long as you stick to the instructions and take care when handling your tools. Once the system is up and running, however, you can’t just expect to leave it be and let it do its work without ever checking up on it. Whole house water filters require regular maintenance, so be sure to bear these simple tips in mind to keep your filter in peak condition:

  • Look Out For The Signs – There are certain signs or signals you’ll want to keep an eye out for that could indicate that something has gone wrong with your filter or the media needs to be replaced. If you notice that the water in your home has suddenly changed taste, smell, or appearance, for example, you may need to check out the filter cartridges and replace them. Other signs include sudden drops in water pressure, which could be caused by one of the filters getting clogged up, as well as strange noises, irregular flow rates, or any alarms or lights on the filter unit itself.
  • Always Read The Manual – This tip applies for pretty much anything you buy in life, whether it’s a whole house water filter or a washing machine; it’s always a smart idea to read through the manual or instruction guide thoroughly. It may not be the most riveting of reads, but an instruction manual will tell you all you need to know about your filter system, introducing the various components, showing you how to set it up, and telling you what to do if anything goes wrong as well.
  • Replace The Filters In A Timely Fashion – As pointed out earlier on, the filter media or cartridges in your whole house water filter system will wear out over time and will eventually need to be replaced. This isn’t optional. If you leave clogged or worn out filters in your system, it simply won’t work as intended, and you’ll start getting dirty water pouring out of your faucets and showers again, rendering the filter utterly useless. Most instruction guides will tell you when the filters should be changed, so be sure to stick to these times. A good tip is to set yourself reminders by writing down the dates when you last changed the filters so you don’t forget.
  • Use The Right Filters – Be sure that when you do replace the filters in your system that you’re using the right filters. Different cartridges and filter media are used by different brands and in different countries around the world. Be sure to use appropriate filters for your chosen model and location, as other filters may not fit correctly or work properly with your unit. It’s also wise to buy the filters in advance so you can change them on the fly, as needed, rather than having to wait for new ones to be delivered when the time comes. Be sure to store them in dry, cool places too and make sure not to damage them.

FAQ

Yes, if you happen to be buying a whole house water filter system to deal with a hard water problem in your home, you need to choose with care, rather than simply buying the first model you spot. Some filters are specially designed for hard water softening and filtration, able to remove high quantities of common elements found in hard water sources, like calcium and magnesium. Be sure to check on your chosen filter that it can remove these elements, and look for other signs or features that suggest the model has been designed to deal with hard water in general, as some filters are more focused on things like pathogens and organic materials, rather than hard water elements. You may even want to install a separate hard water softener, along with a filter system.

One of the things some people worry about before buying a whole house water filter is whether or not it might reduce their flow rate, leading to water from faucets or showers coming out in a trickle, rather than a steady flow. So can a water filter system reduce flow rate? Well, it is possible that the flow rate will be a little slower with some lower quality systems, but the best whole house water filters that remove fluoride and chlorine are designed to act fast, filtering water while maintaining a strong and steady flow, so you probably won’t notice any changes whatsoever, as long as you buy a high quality water filter system, like the Culligan WH-HD200-C.

Another common questions people have regarding whole house water filters is “Where should they be installed?” Well, the exact location for each filter can vary from one model to the next, with some being recommended for indoor installation, and others being fully suitable for outdoor installation too. Most of the time, the right location installation will depend on where the water enters your home. You’ll need to find the main water supply valve or shutoff location in your property and then install the filter there. This valve might be indoors or outside, depending on your home. If it’s outside, be sure that you opt for a whole house water filter that can handle different temperatures and withstand the elements.
