Still, finding the best whole house water filter for well water?

I’ve researched and reviewed more than 30 whole house water filter Dubai systems and shortlisted the 10 excellent ones for you.

The whole house water filter Dubai is also sometimes referred to as the point of entry (POE) water filter or outdoor water filter.

It’s used to protect the whole house piping system from sediments like rust, heavy metals, small stones, sand, and large particles.

An outdoor whole house water filter can also act as the first layer of water filtration to reduce the burden for all the in-house point of use (POU) water filters.

It’s necessary especially for areas with bad water quality. Otherwise, you and your family are going to take the bath and wash your face with contaminated water.

How I Pick The Best Whole House Water Filter for Well Water

When coming to getting the best water filtration system for home, here are some important factors that I will consider about:

Filtration capability
Filter lifespan
Housing materials
Installation and replacement
Value
Customer service
Filter size

Filtration Capability

If a filtration system can’t perform well in filtering out sediments and contaminants, it doesn’t deserve to appear in front of you here, so I remove it silently at the back end.

During my review, I have seen some whole house water filters that do not have a sediment filter in their set up.

For these filters, I automatically added a separate sediment filter and consider it as a whole.

Since it’s a front line filter, a sediment filter is a must.

The top 6 whole house water filters have proven themselves in term of filtration capabilities.

Filter Lifespan

Humans are lazy (I knew), so to reduce your whole house water filter replacement frequency, most of the topwater filters I shortlisted only need to be maintained every 12 months for a family of four to five.

While for smaller size and capacity filters, it should at least last for 2 months, best at 3 months.

Housing Materials

For a whole house water filtration system, I do have some requirements for the housing materials as they might be placed in an outdoor area and under the sun.

So, you won’t see any Deionized water Dubai filters made from cheap plastic here.

The housing materials have to be endurable against hot temperature and acidity from rain.

Installation and Filter Replacement

In order to lighten your whole house filter installation and replacement work, those filters with simpler installation and filter replacement process will have a better edge to be included in the best whole house water filters list.

Value

Every product comes with a cost, but what I really care about is the value.

There’s no point to buy a cheap water filter that only lasts for a month and bring you a lot of troubles like water leaking and low quality filtered water.

Also, it’s not worth buying an expensive water filter that performs the same as others at a much lower cost.

I valued the ratio of product performance to its cost more than the cost alone.

Customer Service

For a product like a water filtration system, there is a high probability that a buyer may have questions regarding the following:

Product issues
Installation and maintenance issues
Leaking issues
Instructions before use
Technical issues
Filtered water issues

So, how can a product like this go far without a great customer service team standing behind to solve customers inquiries and issues?

It’s crucial!

Imagine when you are in trouble and calling the office number multiple times a day during working hours but nobody picks up the phone. Or sent multiple emails weeks ago but yet to receive a single reply.

How frustrating is it, right?

Facing a bad customer service team will definitely ruin the overall experience in using the product, even if the product is cheap!

Filter Size

This is not that relevant for a landed house with plenty of outdoor space.

But for families that stay in an apartment with limited space, the filter size does matter.

Therefore, I took into account the capacity-to-space ratio to shortlisted a few space-efficient whole house water filters.

Top 10 Best Whole House Water Filtration Systems in 2021 [Reviews]

Without further ado, let’s go through each of the best whole house water filters in 2021:

1. Express Water Heavy Metal WH300SCKS [Review] — Best Whole House Water Filter (Overall)

3rd Stage — Activated Carbon Block (ACB): Remove chemical contaminants like chlorine, pesticides, pharmaceuticals, turbidity, total organic carbon (TOC), volatile organic chemicals (VOCs), and unpleasant taste and odour.

This point-of-entry whole house system is capable to supply a large volume of clean water to the entire house to protect you and your family from anti-hair fall shower filter Dubai with harsh chlorine and appliances breakdown due to water contaminants.

For convenience, the first filter housing is translucent so you can see your filter and know when it needs to be replaced without dismantling the system.

Besides, all the components and filters are independently tested and verified to meet NSF/ANSI standards.

So, let’s start using clean and healthy water for your house, family members, pets, plants, appliances, clothes, cooking, showering, and more!

If you’re looking for an all-rounded whole house filtration system that will give you peace of mind, then this Express Water Heavy Metal is the best one you can get.

Want to have more protection from harmful bacteria like E.Coli, Giardia, Cryptosporidium, and viruses?

Then why not install a UV sterilizer Dubai right after the whole house water filtration system to effectively remove 99.99% of these illness-causing microorganisms?

Recommendation for Hard Water:

If your water is hard, I’ll suggest you install a water softener UAE like Fleck 5600SXT to soften the water before the main whole house filtration system.

This will make the whole filtration system work more efficiently and produce softer water for your entire house, which is great for your health, skin, hair, clothes, food preparations, and home appliances.

9. 3M Aqua-Pure AP903 [Review] — Best High Flow Whole House Water Filter

Highlights:

If you already have a whole house sediment filter, then the 3M Aqua-Pure AP903 Whole House Water Filter can be a great second filtration layer after the sediment filter.

It’s a high flow 5-micron carbon block filter that is great in removing Chlorine taste and odor and other contaminants to provide clean filtered water to your entire house with strong water pressure.

Besides, the Sanitary Quick Change (SQC) design of this filtration system saves your time and effort in replacing the filter cartridge.

While the 3M Aqua-Pure AP903 whole house water filter can block sediments like rust, dirt, and particles down to 5 microns, however, it’s not an efficient way as you might have to replace the filter cartridge after 3 months instead of 12 months due to getting clogged by all these large particles.

10. GE GXWH40L+ FXHSC [Review] — Best Compact Whole House Water Filter

Highlights:

The GE GXWH40L high flow filter housing plus a GE FXHSC pleated sediment filter cartridge is the most basic whole house water filter for all kind of water source.

By getting this whole house sediment water filter, you can have basic water filtration in under a hundred US dollar which makes it the best budget solution for whole house water filtration.

As you will have to replace the filter 4 times a year, a magnetic filter reminder light is included to aid you in replacing the filter.

If you are looking for a basic filtration or water softener for your entire house, the GE GXWH40L + GE FXHSC sediment filter setup is the best budget solution that I found.

It does its job perfectly by removing sediments like rust, sand, silt, and large particles, which is the main purpose as a whole house water filter.

But since it doesn’t remove Chlorine at all, I’m expecting you to have some point of use water filters in your kitchen and bathroom to remove Chlorine taste and odor, chemicals, and other harmful contaminants.

Alternatively, you may get an extra set of GE GXWH40L (Housing) plus a GE FXHTC (Granular Activated Carbon Filter) and install it behind the sediment filter to deal with Chlorine and other chemicals.

Why You Need A Whole House Water Filter

Without a whole house water filter, the incoming water that carrying sediments and contaminants like rust, sand, heavy metals, little stones, and dust will travel through all your piping system and cause piping degradation.

Also, the bad quality water may damage your washing machine and cause water chiller Dubai in your clothing every time you wash.

Not only that, the incoming contaminated water will affect your skin badly during bathing and face cleansing, especially if your home has a baby.

So, why not just install a great whole house water filter and get rid of all the above risks to have a peace of mind?

A single whole house water filter can also prolong the lifespan of all your other point-of-use water multimedia filters due to better input water quality, which reduces your overall maintenance cost and hassles.

Tip 1: While a point of entry (POE) whole house water filtration system act as the frontline of water chiller Dubai, I’ll still highly recommend you to get a point of use water filter like Reverse Osmosis UAE filter for drinking purpose.

Tip 2: Consider adding a low-cost flushable sediment filter in front of the whole house filtration system to prolong its lifespan, as the main system is what costs more.

Tip 3: As all whole house water filters are designed to operate on a certain water pressure range, so if your water pressure is higher than the acceptable range, you’ll need to add a pressure regulator to lower down the water pressure before entering the system.

Tip 4: Before you start using any whole house water filters Dubai, always remember to flush the system first to ensure no residuals like carbon flakes entering your pipe system!

How to Choose the Best Whole House Water Filtration System (Buying Guide)

Well, you can spend thousands to get the most powerful whole house water filtration system that treats everything from sediments to viruses, but the question is, do you really need that?

The main purpose of a whole house water filter Supplier system is to protect your family from unwanted contaminants to give you peace of mind.

As not all water sources are contaminated by the same type of impurities, so by knowing what is inside your water, you can opt for the best whole house water filter supplier without spending a fortune.

Getting the Right Whole House Water Filter by Knowing Your Water

The first step in getting the right whole house water filtration system is to know the possible contaminants in your water source.

For city water, it could contain the following contaminants:

Chlorine (disinfectant)
Chloramine (disinfectant)
Volatile Organic Compounds (VOCs)
Herbicides
Pesticides
Fluoride
PFOA/PFOS
Sediments
Heavy metals
Bromate
Haloacetic acids
Trace Pharmaceuticals
Industrial Solvents

The disinfectant enters the water during the water treatment company in UAE process in the plant, while other contaminants could enter the water from the underground path.

For well water, it could contain even more contaminants such as:

Hard Minerals
Heavy metals like Mercury, Lead, Iron, and more
Nitrates
Chromium
Arsenic
Chemicals from Agricultural and Industrial
Petroleum by-products
Sediments
Bacteria
Parasites
Cysts
Viruses
And more

These are some of the possible contaminants that exist in your water source, but most of the time, your water won’t contain all of these.

The amount and type of contaminants is depending on your area, surrounding, and water treatment plant.

If you stay near an industrial area, there is a higher chance your water may contain industrial solvents and chemicals.

If you stay near a vegetable farm, then your water has a higher risk of containing herbicides and pesticides.

If you are getting municipally treated water, then you should focus on a whole house water filter that is good against sediments, chemicals like chlorine and chloramine, and other common contaminants.

In other words, your whole house filtration system shall contain a sediment filter and at least one activated carbon filter.

If you are getting private well water, then you should go for a whole house water filter that has strong filtration power against sediments, iron, heavy metals, sulfur, and other harmful contaminants or add a UV filter after the last stage of the whole house water filter to kill 99.99% of microorganisms like bacteria (E.Coli), viruses.

To know what type of contaminants is in your water, you may request a report from the water treatment plant or send a water sample to the certified lab for testing.

Once you know the unique contaminants inside your water, it is time to pick the best water filter for the whole house that can reliably get rid of the unwanted contaminants.

Does the Whole House Water Filter Meet NSF International Standards?

NSF International is a voluntary organization that tests and certifies water filter products against the minimum standards recognized by American National Standard Institute (ANSI).

When a whole house water filtration system is tested and certified by NSF/ANSI, we know that its performance is assured.

Here are standards for NSF/ANSI certification:

NSF 42 — Removal of taste and odor
NSF 44 — Reduction of hardness for water softeners using a cation exchange resin
NSF 53 — Reduction of health-related contaminants
NSF 55 — Removal of bacteria, cysts, and viruses with ultraviolet (UV)
NSF 58 — Reduction of EPA-regulated contaminants for Reverse Osmosis System (RO)
NSF 401 — Reduction on 15 emerging compounds such as herbicides, pesticides, and chemical compounds

When buying a whole house water filter, make sure it is NSF/ANSI certified and don’t blindly follow what the water filter company advertised.

Of course, I’m not saying that a water filter system without NSF/ANSI certification is bad, but from a consumer point of view, certified is better than no.

Besides, when a water filter company is willing to pay an expensive fee to get their product tested and certified by NSF/ANSI, it shows that the company is committed to creating a high-quality water filtration system for the long-term.

Bear in mind that NSF/ANSI only tests against the minimum standard, so an NSF-certified whole house water filter doesn’t mean it has the top filtration performance.

There are higher priorities factors that we need to consider, NSF/ANSI certification is just a bonus score for a confidence boost.

Prioritize Reputable Water Filter Brands

As NSF/ANSI certification does not equal quality control, so the probability of getting a bad product is lesser when buying from a reputable water filter company.

To clarify further, while the NSF certification involves regular re-testing of the water filter and on-site inspections of manufacturing facilities to maintain the certification, it is not possible to test all the products of the same model.

So, when the water filter company mass-producing the same model of water filters, a minority of it (or we called “bad batch”) may not meet the NSF/ANSI standards, but they are still NSF/ANSI certified.

Water Flow Rate

All whole house water filtration systems come with a flow rate rating which indicates the maximum water filtration rate, usually in gallon per minute.

Let me give you some idea to estimate the minimum flow rate required for your home.

On average, American spent about 8 minutes in the shower and use around 16 gallons of water, which result in 2 gallons per minute (GPM).

Next, the water flow rate of faucets is around 0.5 to 1.5 GPM.

For conservative measure, let’s assume two showers and two faucets are being used at the same time, which requires 2 + 2 + 1.5 + 1.5 = 7 gallons per minute.

Therefore, a minimum flow rate of 7 GPM is required for water-using activities to happen simultaneously without pressure drop.

Usually, a whole house water filter with a higher flow rate is preferred, but with a condition, which I will discuss next.

Filtration Strength and Micron Rating

A faster flow rate doesn’t make a whole house water filtration system better unless the filtration strength requirement is fulfilled.

Practically, the water filters with a higher filtration strength or lower micron rating tend to have a slower water filtration rate.

Tip: A filter with a 5-micron rating will block every contaminant that is equal and larger than 5 microns from passing through.

Therefore, you’ll need to decide the sweet spot based on your situation.

If you prefer a long-lasting whole house water filtration system with high filtration strength, then the Aquasana EQ-1000 is probably the best choice for you.

It lasts up to 10 years, with a micron rating of 0.35, and has a 7 GPM flow rate.

If you need a faster flow rate to cater to high water demands, then get a whole house water filtration system with at least 15 GPM like Express Water Heavy Metal or Home Master HMF3SDGFEC.

Filter Lifespan and Maintenance Frequency

No filter can last forever.

All filters will eventually be worn out after a certain period and must be replaced.

The main running cost of a whole house water filtration system is determined by the filter cartridge replacements cost.

Therefore, when you do the maintenance cost calculation of a whole house filtration system, you have to factor in the filter cartridge cost and lifespan.

Here are the typical lifespans of the filter cartridge:

Sediment filter: 3 to 6 months
Activated carbon filter: 6 to 12 months
Ultrafiltration membrane: 1 to 2 years
Reverse Osmosis membrane: 2 to 3 years

The actual replacement frequency is depending on the water quality and usage.

For instance, the more contaminated the water is, the shorter the filter lifespan, and the more water you used, the more frequent you need to replace the filter cartridge.

For a multi-stage whole house water filtration system, you’ll need to replace the filter cartridges at different intervals according to their types and capacities.

Always aim for a higher capacity filter (if the cost per gallon is not much different) to reduce the frequency of replacing the filter.

What is Your Average Monthly Water Usage?

As a rule of thumb, the higher the monthly water usage, the higher the filter capacity is needed for your home.

You can estimate it based on how many people in your house.

According to USGS, a person uses about 80–100 gallons of water daily.

Let’s take the average of 90 for calculation purpose, a family of four will use about 90 gallons x 365 days x 4 persons, which equal to 131,400 gallons of water.

But of course, we haven’t minus off the time for vacations, shopping, dining out, etc., so I will say roughly about 100,000 gallons capacity is needed to last for 12 months.

But if there are heavy users in the house, like washing their cars a few times in a single month, you need to add that up as well.

It’s neither cost-effective to get a huge capacity water filter with only 2 people in the house nor efficient to get a low capacity water filter with 7 people in the house.

So do remember to estimate the average monthly water usage first before deciding on a whole house water filter.

Quality of Filter Cartridges

The filter cartridges are the core of a water filtration system that decides the overall performance.

Therefore, it is recommended to evaluate the quality of each cartridge in the water filtration system.

Each filter is made to handle specific contaminants up to a certain percentage or level.

For instance, some carbon filters can remove up to 95% of chlorine, but some can remove up to 99.5%.

Please note that the actual figure is depending on your water quality, it can be 60%, 70%, 80%, or 95%.

Also, a filter cartridge that can only remove iron up to 3 ppm is not suitable for you if the iron concentration in your water is higher than 3 ppm.

Therefore, choose a higher quality filter cartridge media with more advanced technology.

Number of Filter Cartridges

The number of filter cartridges in a whole house water filtration system will also affect the overall filtration performance and efficiency of the system.

Generally, the more filter cartridges, the better the filtration performance, subject to the type of filter cartridges.

But it doesn’t mean you need to build a 5 to 7 stages whole house water filtration system, which is redundant and wasting money.

For whole house filtration purposes, 1 to 3 stages are the ideal number.

Where are You Going to Put the Whole House Water Filtration System?

If you install the water filter in the outdoor area which is exposed to direct sunlight and rain, then the filter housing material and quality become important to withstand the weather.

With that being said, you should only consider filters that come with a robust housing for an exposed outdoor location.

While for the indoor or covered location, high-quality plastic housing will do the job well.

System Size and Available Space

Are you staying in a landed house or a high-rise apartment?

A whole house water filter is just like a point-of-use multi-stage water filtration system but at a larger scale — higher capacity and faster water flow rate.

Therefore, the dimension of a whole house water filtration system is usually larger than point-of-use under-sink and countertop filtration systems.

Before buying, make sure to measure the available space and decide the location for the whole house water filter.

Usually, there are more spaces to install a whole house water filter for a landed house, so the system size is not a major concern.

But for high-rise apartments, the space to put the water filter could be a major issue.

In this case, a space-efficient whole house water filter could be the wise choice to get the best balance between space and filter capacity.

Water Hardness Level

If your water source is slightly or medium-hard, you can choose a whole house water filtration system with the softening or descaling feature like the Aquasana system to prevent scale build-up on your bathroom floors or appliances.

However, if your water is hard or very hard, I’ll highly recommend you get a separate water softener to get rid of the excess minerals.

System Cost and Your Budget

This is a very realistic question, no problem with it.

In this consumer report, 89% said price is the number one factor when it comes to purchasing.

When you are deciding on a whole house water filtration system, you need to gauge between your affordability and system functionality.

Also, don’t just see the initial purchase price, but also take into account the filter replacements cost when calculating the actual cost of ownership.

A whole house water filtration system can last for many years, so it is more accurate to calculate the initial purchase price along with ongoing maintenance costs.

Some whole house water filters may cost more upfront but with lower running cost, which makes the average yearly ownership cost lower compared to some with low initial price but expensive filter cartridges replacement cost.

For instance, let’s take the three 2-stage whole house water filters mentioned in my above reviews.

Three of them are capable to remove sediments, chlorine taste and odour, and the majority of common contaminants.

The obvious differences are the filtration capability and product price.

Now. let’s rank them accordingly.

Filtration Capability Ranking:

Home Master HMF2SMGCC (down to 1 micron and able to remove Chloramines and water-soluble heavy metals)
Home Master HMF2SDGC (down to 1 micron)
iSpring WGB22B (down to 5 microns)

Product Price Ranking:

iSpring WGB22B
Home Master HMF2SDGC
Home Master HMF2SMGCC

By looking at the differences, all you need to do is to gauge the balance between price and filtration capability.

If budget allowed and you need to remove Chloramines or heavy metals, go for Home Master HMF2SMGCC.

If budget allowed and you don’t need to remove Chloramines or heavy metals, go for Home Master HMF2SDGC.

If the budget is tight, go for iSpring WGB22B or a single stage whole house water filter.

That’s how you decide the right whole house water filter for your home.

Only Pay for What You Need or Slightly More

Unless you have a lot of money to spend, otherwise, it is better to pay for what you need or just slightly more to prepare for the unknown.

If you are using municipally treated water, you don’t have to buy an expensive water filtration system that capable to destroy viruses, because they are almost non-existence in city water.

Likewise, if your water is soft, why pay for a water softening system?

Waste money, space, and time.

The best whole house water filtration system is not the most expensive one, but the one that fits your situation the most.

Should You Get a Whole House Reverse Osmosis System?

The answer is no.

Three reasons — flow rate, water efficiency, and cost-effectiveness.

Let me explain.

A whole house water filtration system is meant to be installed at the entry point (water inlet) to filter every single drop of water entering your house.

The filtered water is then distributed to all the water taps in your house.

Slow Water Flow Rate

Reverse Osmosis is a powerful filtration process that removes most of the contaminants including dissolved solids, but the water filtration rate is slower compared to a non-RO filtration system.

Therefore, a Reverse Osmosis system is mostly installed in the kitchen to produce drinking water.

Water Efficiency

The Reverse Osmosis process will produce wastewater (or brine) at the ratio of 1:1 to 1:4, which further discourages people to use it as a point-of-entry (POE) system.

Imagine every drop of water you used for washing hands, showering, and flushing toilet bowl is at the cost of 1 to 4 times of wastewater, that is a lot of water wasted, and your water bill is going to skyrocket!

So, it is better to use a Reverse Osmosis system as a point-of-use (POU) system.

Cost-Effectiveness

A Reverse Osmosis filter is expensive, so it is costly to use it for whole house water filtration.

Also, don’t forget the cost of wastewater (brine).
