best whole house water filter

what is best whole house water filter

A whole house water filter system, also known as point-of-entry (POE) filtration system. Why is it necessary in our time, the answer is because millions of Americans consume water unusable originally. According to a documented scientific study,In which millions of US citizens consume unsafe drinking water, causing diseases such as cancer, stomach flu, neurological disorders and others. “You can see the entire study here or here

Here you will have only two options
Either buy mineral water from the grocery store or buy a whole house water filter for your home
It is unreasonable to continue to buy water from the grocery store because it is expensive and not enough for cooking, drinking and washing and it will be very expensive ((in addition to the burden of carrying it home))…

If you want a clean water in all taps home Or your only problem is drinking water.and In order not to waste much of your time searching for a whole house water filter or a reverse osmosis filter. Or even losing money in searching for products you do not know its flaws or characteristics.
We have searching For more than 30 hours of research and experimentation to reviewed for you the best whole house water filter and if you want to filter reverse osmosis we also reviewed it for you here

What are the most important criteria for choosing a WHOLE HOUSE WATER FILTER?

1. Water quality

The most important thing before you get a whole house water filter you should know more about the quality of the water you receive. This allows you to buy the right filter that can handle all the pollutants in it, whether you consume municipal water or your well water. Because this is necessary for selecting the filter as each filter focuses on a particular type of contaminant.
In order to know the material that will contaminate your water, you will need either to send it to a special laboratory, or you can buy a water test from Amazon which will give you a rough idea of the pollutants in your water.
If you are a resident of a US city and your water source is municipal water, you can see the quality of your water here or here.
In general, if you are a city dweller, your water will often be contaminated with chlorine
And substances resulting from its use such as trihalomethanes and haloacetic acids, which have linked some studies between them and bladder cancer.
In addition, most municipal water is fluoridated, studies have been linked between fluoride and damage to teeth and bones and also cause bone cancer. The bad news is that only a small number of filters will help remove fluoride from your water if the test proves that fluorine is too high in your water.
You can see the studies listed in the Resources
As for water wells are often contaminated with heavy metals and agricultural pesticides, fertilizers, herbicides and microorganisms. There is also an opportunity to pollute your water with bullets and metals from the old pipes.
All these reasons make it necessary to get a WHOLE HOUSE WATER FILTER

2-Filter Lifespan

Filter Lifespan is one of the most important factors for choosing a whole house water filter, because after the cartridge life is finished you will need to purchase a new filter cartridge.
This means that IF you choose a short life filter that means you will need to buy a cartridge every few months for this.
But what filter Lifespan depends …. ???
Filter Lifespan usually depends on the total amount of water filtered by the filter over a given period of time.
Means Whenever you consume more water, and Whenever your water was polluted more,  you will need to buy a cartridge soon as possible.
The life of filters typically ranges to 100,000 gallons consumption may reach in some species to one million gallons a maximum possible.
A filter that purifies 100,000-gallons will be enough for a family consisting of four members for a full year, then you will need to buy a new cartridge.
the filter that purifies one million gallons will be enough for a family consisting of four members for a full ten years before the need for replacement of cartridges.                                            Note: that the average person consumption of up to 80 gallons per day a maximum possible.

3-Flow rates

The flow rate is necessary to know because getting a filter with low flow rate means you will not be able to use the bathroom or faucets well.
You will also have many problems with water pressure at home, so we recommend getting a filter with a good flow rate, and most of the whole house water filter we reviewed have a flow rate of more than 15 gallons per minute.
It is an excellent rate and will not have any problems with the water pressure of your house faucets.

4-Effect of the filter

At the same time as you want a good flow of water in every faucet of your home, you should be aware of how effective the filter is
The effectiveness of the filter means the power of the cartridge in water purification, measured by micron and micron is one millionth of a meter
Which divides the meter into one million sections and one of them is called Micron
And yes it is very small, the more the filter cartridge has smaller pores the more protection it provides.
The maximum protection in whole house water filter is 0.35 microns, which is excellent protection and purification of your water from chlorine, fluoride, lead, heavy metals, herbicides, etc. But the protection of home filters ranges from 40 microns to 0.35.
While the protection in reverse osmosis filters reaches 0.00001 microns, the osmosis filters make the water pure and safe 100% but its disadvantage is that it provides water for one tap and also consumes plenty of water, half of which goes as sewage.

5-Annual cost

We all want to save money and that’s why you’re reading my article now so the cost of filters is not limited to the initial purchase price.
different types of whole house water filter will need to be changed every time they are consumed. And when their pores closed with sediment and contaminants, when purified for a certain amount of water starts at 100 thousand gallons up to 1 million gallons.
So it is important to know that you will need to buy new cartridges every six months or every year and may reach in some species to 10 years.
The filters life depend on two factors: your consumption of water and the extent of your water pollution, so you have to calculate your household’s water consumption relative to the filtration capacity of the filter
A person can consume up to 80 gallons per day, and the filter’s capacity is typically 100,000 gallons. With a simple calculation, you’ll know how long you’ll need to buy a new cartridge.
In addition to knowing the quality of the water pollutants, then you will choose the filter that will withstand your water pollutants better. The filter of water wells is different from the municipal water filter and so on
Some filters include a sediment prefilter, which eliminates dust, rust, silt and large particles. This initial filter provides excellent protection for other filter filters that purify fine particles such as chlorine and heavy metals and prolongs its lifetime saving you good money, but you will have to replace it all Three to six months.

6-The space

You may wonder where you’ll put the whole house water filter and how much space it will take.
The answer is that the whole house water filter must installed in the place where the water enters the house before the heater or any other device.
This will help you protect the heater and other appliances such as washing machines as well as pipes from different pollutants.
You’ll get both hot and cold water a pure. Just keep in mind that the whole house water filter is much larger than normal filters and may need a lot of space to put in.
We have mentioned the dimensions of each one in the whole house water filter that we reviewed.

7-NSF and WQA seals

It is always better for you to make sure that the whole house water filter system You want to buy it has a compatibility sign with the NSF standard.NSF the “National Sanitation Foundation”    Or you can check if it has a WQA (Water Quality Association) seal on it. These certifications mean the filter has proved its quality through vigorous testings by the most prestigious organizations in America.
I would recommend always looking for or asking about these certifications. If a water filter system is certified in one of these ways then you can be assured of its quality, and relax in the thought that your drinking water is in safe hands.

The WGB32B whole house filtration system is the ideal “” point of entry “” filtration system for cleaning up water supplies to a home or business on municipal (city) water. Unlike “point of use” systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB32B filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WGB32B.
This filter has the largest filters in the market, which means that more water flow in addition to a longer life of filters and provide a flow of 15 gallons per minute, in addition to the company provides excellent support by telephone and e-mail, this filter also consists Three stages are as follows
1 – the first stage of filtration protects against large particles such as sediment, rust, sand, dirt and heavy metals. This filter uses a multi-layer technique, giving a more gradual filter, which means that the cartridge is less likely to clog quickly. Simply put, the outer layer of the filter contains larger holes (larger microns), and the holes become smaller as the filter approaches the inner layer. This has the effect of reducing clogged pore filtration which can cause loss of pressure. This also means that filters will continue to work a little longer. This filter provides protection to 5 microns, which means that only smaller particles than 5 microns will pass through.

2-The second and third phases  made of the same type of filters. They made FROM active carbon and  designed to remove 95% chlorine, iron, sulfur, herbicides, arsenic and various chemical contaminants. It also removes bad taste and odor. 4.5 inches is a standard among many different filtration systems, and its characterized by the existence of several different types of cartridges, one of which dedicated to the removal of mercury, arsenic and dangerous metals
There is a dedicated PCB removal and treatment city water

There are also several versions of this filter and we will explain it to you now

The 3-phase water filter is now available in 3 different filtration configurations. There is the ordinary carbon filter we just mentioned, and now two specialized versions. They deal with heavy metals such as lead, copper and iron. The carbon version is impressive for municipal water supplies, while heavy metal filters are well suited for well water supply. Take a look at how the three systems compare in the table below:


This full home water filter will do a great job of protecting your home from most harmful water pollutants. They are strong enough to protect against the most common pollutants. If you need something more powerful, water reverse osmosis filters is the next best thing. However, they will not filter all the water in your home (at one point only). This is the tradeoff between the two filtration systems.

The iSpring WKB32B does not include bypass or shut off valves, and will require soldering to install. The bypass valves and pipe are necessary or you will have a really messy time when it comes to changing the filters. They can be purchased at relatively little expense to add at installation. The filters themselves are pretty easy to change and just require a wrench, and a bit of muscle. The user manual is available to read here.

The only negative point in this filter may be the slightly higher price

The Whirlpool filter is a complete filter system with a single filter that uses a whole new way to purify the whole house. The central water filtration system uses a filter bed with activated carbon so there are no filters for replacement or maintenance like the other whole house water filter.
Unlike other systems, the central water filtration system will not reduce domestic water pressure. With FilterSense ™, the central water filtration system automatically cleans the internal filter every 14 days. The system can also be programmed to clean itself more or less frequently depending on the water conditions in your area. The self-cleaning process takes about 3 minutes.
It is a new solution that allows you to experience the benefits of filtered water throughout your entire home without maintenance. Imagine all drinking water, cooking, bathing and washing water without contaminants at no additional cost and inconvenient replacement of filters.
Unlike the whole house water filter, this system will produce some wastewater. Operating in this way also means that the filter media cannot be replaced, and after the life cycle of the 10-year or 1,000,000-gallon units, the entire system must be replaced. However, as it does not require replacing the filters every few months, such as every whole house water filter, this is not as expensive as it sounds.

And with no filter replacement and therefore no running costs (except for electricity), then this works out as a home water purification system at a very affordable price on 10-year work. In fact, if you are working from the average cost of a complete home water filter system over 10 years (unit + filters), this makes this whole house water filter one of the cheapest whole house filter that we reviewed.
It does not look very good compared to some filters like iSpring WKB32B, but if your only problem is chlorine and sediment, this filter is very effective in purifying the chlorine. And impurities in the water of the city but is not effective in the water wells or water containing a high proportion of minerals such as iron because that may damage the basic filter because of the accumulation of iron particles inside.
The system is controlled electronically and features a display screen and buttons at the top. By using these controls, you can control the frequency of system cleanup. Also, if there is a problem with the flow rate you can press the button for manual cleaning. You can install the filter easily without having to a plumber see the video below

Aqua-Pure AP903 This system is the best whole house water filter in terms of maintaining water pressure at home. It is also very effective in removing sediments and chlorine and filtering all pollutants greater than 5 microns and this protection is excellent for the price of this unit.
The most wonderful thing is that you need to change the filter cartridge once a year or after 100,000 gallons, replace it with ease and can only clean the cartridge.
The unpleasant news is that this filter does not contain a pre-filter for this unfortunately it is not effective in water that contains a high percentage of sediments or minerals such as water wells, and there are other types of filters effective in the water wells like ……. However, The filter is a great solution for the water of the city, taking into account the initial cost of purchase and the cost of changing the annual cartridge, which is about 60% of the price of the filter is considered one of the most appropriate whole house water filter price, and also require no contact with the filter media during cartridge change-out.

The filter Home Master HMF2SDGC is a smaller version of the filter Home Master HMF3SDGFEC that the only difference between them is that this type is used candidates instead of three as in ALSO it cheaper, and is considered one of the best whole house water filter This filter consists of two phases.
The first stage is a sediment filter that removes particles (dirt, sand, salt, rust, etc.) from your water supply. It has multiple layers and purifies particles to 1 micron and this is considered an excellent protection for most filters. Will last anywhere from 6 to 12 months, depending on the level of use and the amount of water pollution.

Filter Stage 2: This filter is specialized in reducing iron, sulfur and manganese from water (until 95% clearance). This helps to keep the life of household appliances that use water, as well as pipes, water heater. The life of this filter really depends on the amount of heavy metals (like iron) in your water. You can test your water to see exactly what you should be concerned about the contaminants.
The system of the two units is wonderful in the work in the city and is excellent in the purification of chlorine and minerals as well, which is cheaper, but if your water water wells contain a large amount of iron and heavy metals we recommend using the three-stage model.
This filter comes with a two-year warranty and large filters, which means faster water passage and longer filter life.
Maintenance and installation is easy and relatively simple If you have some experience in plumbing, you will need to cut some tubes It may take an hour to two hours to install the unit, and we recommend local plumbing if you do not have enough experience and you can see more on the installation guide here, The three models of this unit are available in the market

  • Suitable For All Source: It is suitable for all water source
  • Excellent Filters: 4 Layers sediment, carbon, and iron filters remove most of the contaminants in the water. Long lifespan of the filters.
  • Great Flow Rate: Massive oversize filter provides greater flow rates to your home.
  • Two years warranty
  • Filtration of objects larger than 1 micron
  • Improve the taste and smell of water
  • Huge filters
  • The cartridge life is up to a year
  • Replace cartridges every 8 to 12 months


DuPont FPF13003B is the cheapest option on the market. This is the cheapest whole house
Water filter in the market.
This filter consists of only one unit and is effective in filtering impurities greater than 10 microns or depending on the type of cartridge you will purchase.
Or if it is used with another type of filter as a primer, it is effective with dust and rust but not effective with chlorine or heavy metal but can protect the main filter and increase its lifetime, or a very smart idea is to arrange three or more of the filters in sequence. You could start with a 10 to 20-micron filter, followed by 5 microns, and a 1-micron filter at last. This setup is reasonable to guarantee excellent drinking water quality safe for consumption.
It also has another advantage that it is very easy to install will not only need basic plumbing skills, but we must admit that it is ineffective that the installation of one piece of them and in general the level of very much less than the other filters in remove chlorine and other pollutants,
You must replace the cartridge after purifying 15,000 gallons, but it still provides a great choice for people with limited budgets. This is all we have about this filter.


This is another filter and can be considered as one of the cheapest filters for the whole house. As in the previous unit, this cheap unit, which can cost only a few dollars, can get rid of the big impurities, rusts and salts.
But it is not effective in removing chlorine, heavy metals and other dangerous pollutants, so it is successful only when combined with another filter, and it will be very effective if used as a primary filter for the main filter in this case is very effective in maintaining the main filter and prolong his life, It costs you only a few dollars to replace it and this is a great deal in protecting the main filter and prolonging its life, this is all about this unit which is the last one in the list of the best filters for the whole house

How Does a Whole Home Water Filter Work

The entire house filters use different means to remove contaminants. The filter is usually attached to the main water line before the water heater, so all water will be filtered into the house.
When water enters the filtration system, it will filtration by sediment prefilter, which eliminates dust, rust, silt and large particles.
However, this is not his only work. This filter also plays a key role in maintaining the function of the following filters for a longer period of time. Without this filter, other filters will need more frequent changes.
After the water has passed out of the pre-sediment filter, it must pass the activated carbon filter. This is one of the most important components of the filtration system, which plays a crucial role in removing many pollutants. Activated carbon offers a large porous surface. This surface aligns with the corners and cracks, and the pollutants in the water are attracted to them through a natural process called adsorption. This filter is very effective and will remove most of the chlorine, the remaining sediment, ie volatile organic compounds, along with the unpleasant odors and tastes of the water. In some cases, the activated carbon filter is also treated with special materials for different properties. Some manufacturers vaccinate a small amount of silver in the carbon filter to give it antibacterial ability.
When the water comes out of the carbon filter, it passes through the copper, zinc and metal filter. This filter is very important for the filter process because it removes most of the remaining contaminants in the water at this point. This filter will remove the remaining chlorine and heavy metals and has a good effect on bacteria and other microorganisms that are usually found in water.
This is an optional step, and some water filters may not have. However, some models pass water through a water conditioner or descaler. Some manufacturers use ion exchange technology to achieve this. When the water enters the ion exchange filter, it passes through some resin granules. These beads are filled with sodium ions. When magnesium and calcium molecules encounter grains filled with ions, they will replace sodium ions. This will make the water softer, but it will make it slightly salty. Other manufacturers use a salt-free water disinfectant to maintain a neutral water taste.

This is another optional step, but more frequent than a water disinfectant. The candidate after liquidation plays an important role in the production of high-quality water. When water reaches this filter after filtration, it is usually filled with very small particles because the larger molecules are filtered. The role of post-filter is to stop these small particles from reaching your water. These filters look like a network filled with holes, but the size of the holes is what matters. Some post-filtration holes are as small as 0.35 microns, but most of them measure 1 μm.

Another optional but highly effective element is the UV filter. This filter is capable of killing any bacteria, virus, or residual organism that may have survived previous filters. If your water source contains high bacterial contamination, using the UV filter will solve the problem.


How To Install Whole House Water Filter

When it comes to the installation of the Whole House Water Filter, there is no one way suitable for all filters. Each system is different and therefore requires different tools.
