Writen by Ronald Brown

Fact checked by Natalie Bridges

best whole house water filter cartridge

What makes the best whole house water filter cartridge? Because there are many different filter cartridges available, you might not have a great time at all, especially if it is your first time buying this item. It is why we’ve created these reviews of the top choices on the market. They feature the top picks that have great qualities and are by reliable brands known for their heavy-duty and high-performance filters. Buying the top-quality whole-house water filter cartridge hinges on how you appreciate the following factors. These are not absolute, but they can help narrow down your options.

  • Filtration Capacity: Whole-house water filter cartridges must accommodate as many contaminants as possible to ensure cost-effectiveness. Otherwise, you will spend more on replacement filters because they can only last so long. Hence, a 150,000-gallon filter is better than a 100,000-gallon system, provided all other parameters are equal.
  • Contaminants Removed: You might want to test your water to determine the contaminants you must remove. For example, some households only require sediment, chlorine, and CTO reduction, while others might have issues with microorganisms, heavy metals, VOCs, pharmaceuticals, and other impurities. Although any filter can claim water contaminant removal, only those with NSF or WQA certification provide peace of mind.
  • Flow Rate: Water filters reduce water pressure and flow slightly. You do not want the filter to lower your water flow rate significantly because drinking then becomes a hassle. A whole-house system should provide at least 15 gallons per minute.

By using this guide as a reference, you can be sure to buy the right water filter cartridge that matches your preferences and feature requirements. Let’s begin.

Top-Tier Whole House Water Filter Cartridge Reviews

1. GE FXHSC Household Sediment Filter

GE is a popular brand known for its high-quality appliances. However, only a few know that they also manufacture and sell filtration systems. One of these products is its household pre-filtration sediment filter. With this product, you’ll know that it was made with the GE brand of excellence.

As in its name, the GE household pre-filtration sediment filter is installed in the first part of your whole house filtration system. Because of this, this filter is responsible for removing and filtering out sand, silt, rust, debris, scales, and other sediments.

However, unlike other similar filters, the GE sediment is more effective. What I like about this product is that it can also remove chemicals, pollutants, and other microorganisms due to its 30-micron filter. As such, this filter cartridge can effectively improve the taste and smell of your water by removing chlorine, hydrogen sulfide, as well as other chemicals and pollutants.

With this installed, you’ll have a smooth-sailing filtration process.

Another thing I like about the GE household pre-filtration sediment filter is its capacity. Unlike similar brands, the GE model can filter up to 30,000 gallons of water. As such, you will only need to replace it every three months. This enables you to save up on costs and other expenses.

The GE household pre-filtration sediment filter is also versatile and convenient to use. It can fit any GE water filtration system as well as other 10″ x 4.5″ water filtration systems such as Culligan, Whirlpool, Omni, DuPont, Watts, Kenmore, and other brands.

Moreover, this product is also easy to install and maintain. In fact, you can even do the installation process on your own without the need for a professional. Maintenance is also easy as you just need to replace the filter every three months or once it treats 30,000 gallons of water.

The only downside to this product is that it has a slow water flow. Compared to other similar models, the GE model provides only 3GPM. Nonetheless, it’s still within a comfortable range for drinking water.

What Is A Whole House Water Filter Cartridge/ Who Is This For


Tap water, while the most accessible and abundant source for households, contains a lot of contaminants, particles, pollutants, and other impurities. Accidentally drinking it might pose a lot of health problems, especially for children, pregnant women, and the elderly. Using it to clean your surfaces and tiles might also be a bad idea since the water contains a lot of hardness minerals that might damage it.

As such, there is a need to filter water using a water filtration system. One of the most popular types in the market is the whole house water filtration system.

The whole house filtration system, as in its name, is a system that can effectively filter all the water that is currently found in your home. Also known as the Point of Entry system, the top-rated 10 inch water filter cartridge is connected to your main water line so that all your water dispensers in the house will give out filtered water.

In other words, this means that your toilets, baths, faucets, showers, laundry, kitchen, and the like will provide treated water. These whole house filtration systems are usually installed before the heater system. As such, both your cold and warm water are also filtered.

House water filtration systems are for those who have high contamination levels in their tap waters. With this, you can effectively bring down these levels and provide clean and safe water for your household.

Due to its size, the whole house filtration systems are for those who find using the small filtration systems a hassle. With this, you can quickly get your filtered water.

How Does It Work

Just as you would read in whole house water filter cartridge reviews, whole house filtration systems might come in different styles and types. Still, nonetheless, they work in the same way.

These filtration systems are usually attached to your main water line and placed before the electric tankless water heater.

Once the water goes in, the first thing it will see is the sediment prefilter. This filter medium is designed to get rid of large particles such as silt, rust, sand, debris, and other similar sediments.

After the water passes through this, it will then go to the activated carbon filter. This filter has a membrane that possesses millions of tiny, microscopic holes. It provides a more okay filtration process.

As such, contaminants that are bigger than these holes are left behind while the water goes through the next level. Among these contaminants are volatile organic compounds, chlorine, left-over sediments, and other chemicals and pollutants.

Water then goes through a copper-zinc and mineral filter. It is the final stage as it will treat most of the contaminants that are left behind.

There are also some models that offer the optional step of softening or descaling the water using ion-exchange technology. You also have models with UV filters and a post-filter.

What Are The Different Types Of Whole House Water Filter Cartridges


Whole house filter cartridges differ on the type of filter medium/media they use. Some of the most common examples include:

Activated Carbon Filters

These types of filter cartridges are one of the most popular as they can remove a wide range of pollutants, chemicals, and other impurities. It can completely filter out 81 types of chemicals and partially 50 types of others using its porous membrane.

However, while that may be so, they are ineffective when it comes to filtering dissolved metals and minerals, inorganic contaminants, bacteria and viruses, and the like.

Sediment Filters

As in its name, sediment filter cartridges are used to filter out debris, rust, silt, sand, and the like. These are further classified into standard sediment filters, more delicate filters, and ultra-fine sediment filters.

Sediment filters come in a multi-gradient design that contains several layers, each with its micron level. Because of this, it can also remove and filter out a wide range of particles found in your tap water supply.

This type is usually found in the first part of the whole house filtration system. It is to ensure that large particles won’t damage and clog up the other filters that lie ahead.

Iron Filters

One of the most common contaminants found in your water is dissolved minerals and elements. However, not all filter cartridges can remove these easily.

As such, many opt to use an iron filter to do the job. While it can filter out minerals and metals, it’s not that practical when it comes to other impurities.

UV Filters

UV water filter cartridges are there to filter out the deadliest contaminants in your water supply- bacteria and other viruses.

With this water filter, water will pass through a chamber and will be exposed to UV light. This radiation serves to inactivate bacteria, rendering them unable to reproduce and spread.

Advantages And Disadvantages Of Using A Water Filter Cartridge

Having your water filtration system will certainly bring a lot of benefits to your household in terms of health and money. Having a whole house filtration system is even better.

However, like all products, there is a need to weigh the benefits and consequences they will bring. As such, this section will list all the pros and cons of having a whole house filtration system.


High-quality water

No matter how reliable your local water utility is, tap water will always contain bacteria, contaminants, particles, sediments, pollutants, chemicals, and other impurities.

As such, there is a need to filter it with a water filter.

With a whole house filtration system, you will get filtered water right into your home. Since it’s installed to your main water line, it can effectively filter all the impurities out from the water before it enters your home.

Improves Taste and Removes Smell

Aside from removing bacteria, viruses, and other pollutants in your water supply, the whole house water filter will also remove chlorine and hydrogen sulfide. These chemicals are known to affect the smell and taste of your water.


The whole house water filter is more convenient than using the smaller and portable systems since the former can effectively filter out the contaminants and impurities before the water can even enter your home.

As such, you wouldn’t have to do it manually on your own. You just need to turn on your faucet, and the water you’ll use is already filtered.


Having your water filter will also mean you can reduce your bottled water consumption. With this, you are helping save Mother Earth.



Whole house water filter replacement cartridges tend to have upfront costs. These types also require constant maintenance and check-ups. They also rely on electricity to work, and since they’re big systems, you can also expect big electricity consumption.

Buying Guide 


Whole house filtration systems enable you to have filtered water in every water dispenser in your home. It includes faucets, toilets, baths, showers, and the like.

As such, they are quite popular in the market and come in different types and styles. However, this wide array of choices might be confusing, especially for beginners in the water filtration scene.

But don’t worry. This section will list down all the factors that you need to consider when it comes to having your whole house filtration system.

Filter’s Lifespan

This looks at how many gallons of water your filter can treat before you must replace it. A long lifespan of water filter cartridge replacements is preferred since it’ll mean low long-term costs. However, there is a danger of cross-contamination, especially when you don’t replace it on time.

It’s recommended that you buy filters that have a lifespan of at least 1 to 5 years. These systems can usually treat 100,000 to 500,000 gallons of water. With this, you’ll have the best combination of efficacy and affordability.

There is also a 10-year water filter available that can treat up to a million gallons of water; however, they might be too expensive for most users.

Number of Stages

A multi-stage filtration system is recommended since it can remove a broader range of pollutants, sediments, contaminants, and other impurities.

Multi-stage filters can usually filter out sediment, heavy metals and chemicals, and chlorine from many gallons of water. There are also those that come with optional filters such as the UV filter, a post-filter, and a water softener. With this, you are ensured that your water is adequately treated and is of high quality.

Aside from this, multi-stage filtration systems offer convenience. With this, you are spared from the costs of buying multiple filters.

However, if you want, you can always choose a single-stage filtration system, especially when you know what areas to target. But keep in mind that its effectivity rate is lower.

Flow Rate

Sound whole house filtration systems won’t affect the water pressure of your supply and the number of gallons of water. As such, choose one with large inlet sizes and good filter designs to maintain the flow rate for the water pressure.

Easy to Install

Whole house systems require a bit of effort and patience to install. However, if you can, it’s recommended that you get a system that is easy to install by yourself. No one wants a system that is frustrating and difficult to install. You also have the option of hiring a professional to help you out.

Warranty and Customer Support

For multi-stage filtration systems, it’s most suitable to have at least a 2-year warranty. With this, you are protected from most problems.

Moreover, if you choose to have a filter with a long lifespan or large capacity, then you should ensure that it also has an extended warranty.

Another thing to look out for is the customer support provided by the company. It’s good to purchase from companies that are attentive to their customer’s needs. As such, when the time comes for queries or replacements, you can always ask them.

Frequently Asked Questions (FAQs)

What’s the lifespan of a whole house filtration cartridge?

A whole-house water treatment filter cartridge can last six to twelve months, depending on the individual filtration components, water consumption, water quality, and filter size (or capacity).

For example, a 20 inch sediment pre-filter that removes silt and other solid particles might only last six months. On the other hand, a carbon-based water filter element could last about a year.

A whole-house filtration system also has a post-filter that screens particulates and organics that escaped the first two purification layers. This component has the same one-year lifespan as the carbon filter.

These figures are estimates because everything depends on how much sediments and contaminants you have in the water. The filter’s capacity can also be a limiting factor. For instance, a 20,000-gallon unit will not last as long as a 50,000-gallon system. Modest water consumption can also extend the filter’s lifespan.

Moreover, we must appreciate that a water filter manufacturer might use proprietary technology to improve its product’s operating lifespan. It is one of the ways they can ensure high-quality whole-house cartridges with a distinct competitive advantage.

What flow rate should you get for water filter cartridge for whole home?

A water filter cartridge’s flow rate is one of the factors assessed by Consumer Reports in evaluating any water filter. Flow rates range from 15 to 40 gallons per minute (GPM) for the whole house.

However, the GPM requirement is lower for under-sink or in-line filtration systems. For instance, the IcePure under sink water filter offers a flow rate of 2.5 GPM, which is above average.

You can also check your home’s ideal flow rate by checking the individual water fixtures. For instance, toilets use 5.0 GPM, while shower heads need 2.5 to 5.0 GPM. Meanwhile, faucets require 1.0 to 2.2 GPM.

Add the number of water fixtures and their respective stats to determine your water filter cartridge’s minimum flow.

Do whole house water filter cartridges reduce water pressure?

Yes, whole-house water purifying cartridges can reduce water pressure. Even professionally installed systems can show a slight drop in pressure.

You might have the top-tier product from a leading whole-house water purifier factory, but that does not mean anything if you have heavily contaminated water.

Filters screen contaminants in the water by trapping substances with a larger diameter than the filter’s pore size. For example, a 5-micron sediment filter for mainline applications can only prevent objects bigger than 5 microns from passing through.

Sadly, sediments and other debris can accumulate “before” the filter over time, preventing liquid from passing as fast as it should.

Are water filters necessary for water softeners?

That depends on whether you just want soft or soft and clean water. Filtration is necessary for a whole house water softener and filtration system. It is worth noting that water softeners do not remove water impurities, including sediments, chlorine, lead, and other harmful chemicals.

Instead, they replace hard water minerals (i.e., magnesium and calcium) with potassium or sodium ions to prevent limescale formation, sink stains, and plumbing corrosion.

Whole-house filters remove sediments and other impurities to lessen the water softener’s load, allowing it to function optimally and making the whole house water filter and softener system efficient.

What are the most trusted water filter cartridge brands?

When shopping around for the best whole house water filter cartridge, you must also check the Ronaqua, Filtrete, and AQUA CREST, among the rest that we’ve featured earlier. They are reliable and quality brands that know how to deliver satisfying and heavy-duty products to their consumers.

What is the best micron for the water filter?

Just like knowing the water filter cartridge sequence, you might also want to know what the right micron for a water filter is. At the very least, it is five-micron because it can ensure filtering even smaller particles.

When should I replace my water filter cartridge?

At the very least, you should replace it every three months. In some cases, it is every six months. It depends mainly on the water quality in your place. In this case, you might have to change it more often if it gets clogged up fast.

Which is better 5 micron or 20 micron?

The 5-micron filter is better because it can filter even smaller particles. For instance, the 20-micron filter has a larger opening, so it will let more solid particles pass through it than a 5-micron filter does.

How many microns is a good water filter?

It is suggested that you get a 5-micron filter because it is more effective in filtering even smaller particles. With that, you can be sure that your water will be healthier and cleaner.

What is the warranty?

Some manufacturers do not include a warranty on their product descriptions. To know about it, you might want to contact their customer service people. Warranty is an essential factor in ensuring that you can get help or a replacement if what you received is defective.

How to care & clean?

They don’t need caring and cleaning because they are replaceable. You need to change the filter when it is clogged and not working optimally as it should. You must replace it every three months at the very least or when it is clogged. It depends on the quality of the water in your place. In this case, you might want to check it from time to time when it needs replacement.
