Our Top Choice: The Aquasana 5-Year, 500,000 Gallon Well Water Whole House Filter with Water Conditioner

Aquasana Whole House Water Filter

Before we move on to the next part of this guide and to the reviews of filtration systems, we would like to first mention our TOP choice. The one we would recommend most in terms of the testing, rating from our research and overall consumer reviews.

We chose a whole house water system because it has the most benefits for large household who want to utilize and consume the best filtered water without the hassle of having to constantly use only ONE particular faucet for clean water.

Also, we chose Aquasana because of its reputable and trusted brand name many legitimate customers have raved about.

So let us show you all about this Whole House Filter from Aquasana. We have separated our review into sections for you to fully weigh its pros and cons and see why we chose it as our top water filter to date.


We first study its design. While the water filter itself isn't the most sleek or modern of bodies, it has the adequate size to fit into many types of plumbing systems. And anyway, we aren't here for a luxurious design, but for its construction and performance.

There are two main blue canisters that contain the filtration kit and conditioner. The canisters are made out of strong and durable material, known to withstand for many years without signs of damage and rust (as long as you place it in a safe area).

Installation and Set Up

The shipping and transaction is fairly easy, as Aquasana is also known for satisfactory customer service. It comes with an installation kit with plastic fittings (but without the tubing, which you can buy separately). Depending on the plumbing system, you can use your own fittings.

Installation can take a bit of time. It's best if you hire a professional if you aren't familiar with how to set up a water filter system. But if you know what you're doing, then you can do it yourself with its installation kit and instructions included.

​Performance and Water Quality

The most important part of the review would be how the water filters perform. And we can say that with its latest technology in killing contaminants and reducing chlorine, it does a great job in filtering water without the need for electricity or drainage.

While the water isn't THAT silky soft, it does the job in killing off all contaminants and bacteria, as well as improving the air indoors.

​Repair and Maintenance or Replacement

As for maintenance and repair you won't need to worry about having to constantly checking up on it. Like what we mentioned, it's made out of the durable material built to last, providing up to five years (ten if you buy 1,000,000 Gallon variant) of filtered water.

One con about this may be because it's a bit difficult to replace the filters. We mean that you will need to regularly replace it because of the many features and purposes the filter has to offer.


The water filter itself comes in an almost complete package. It comes with the filter, a conditioner, UV filtration kit, and the professional installation kit. You even have the choice to have it professionally installed. The one thing it doesn't have would be the PEX tubing, which you can purchase individually.

It comes in various packages too, ranging from its lifespan, capacity, and the features you may (or may not) need.


As for its price, it's quite expensive for a whole house water filter system. But as expensive as you might think it to be at first, its many advanced features and amazing performance makes it worth the investment.

Since the filters are known to last for years without the need to constantly look after it (except upon replacement of filters), you won't need to worry about your water quality in the long run.


    • VERY durable and known to last for many years (depending on the variant you pick and water usage)
    • Excellent customer service and reputable brand name to trust
    • HUGE difference in water quality- No unpleasant taste and odor
    • Proven to have lowered down pH levels and contaminants
    • Includes a water conditioner system
    • Large capacity of half a million gallons (a variant for one million gallons is also available)
    • Filters quickly and efficiently


  • The plastic fittings aren't sturdy compared to the overall design of this filter. We suggest getting replacement fittings
  • It might be slightly difficult for you to replace filters if you aren't familiar with the process.
  • The company warrants it only when it is installed by a professional plumber.

Different Types of Water Filters In Market

Like mentioned above, the first thing you should do when choosing a water filter suitable for you and your loved ones would be the type of filtration system you need. Here are the following water filter reviews of the best products, categorized to where and how to use it:

Best Filtered Water Bottle

Filtered water bottles are ideal for those who are constantly traveling and hiking. If you have been on a long trail before and ran out of water, you might have wanted to drink from the first water source you see. To avoid suffering from the consequences of drinking unfiltered water, a filtered bottle can come in handy.

When adding water into the filtered bottle, it would remove any sediment or bacteria from the water immediately, making it safe to drink. Not only that, but it's compact and easy to carry around when traveling as well. It's a great companion when going out or camping.

1. LifeStraw Go Water Bottle

LifeStraw Go Water Bottle

What's great about the LifeStraw Go is how it comes in various designs suitable for any man or woman. Its hollow fiber membrane filter removes bacteria and sediments WITHOUT the use of chemicals or batteries, making it a healthy choice. It's known to reduce 99.99% of bacteria within minutes.

We recommend the 2-Stage filter, which has an activated carbon filter that would reduce odor and chlorine, making it taste better.

Take note that it's a 23-ounce leak-proof bottle made out of BPA-free Tritan material. It doesn't only look good, but it's as strong as you need it to be when traveling around the world!

No matter where you are, this water bottle will be able to save you and efficiently give you the filtered water you need.


    • Easy to fill water with
    • Very durable
    • Leak-proof but easy to open cap
    • Many designs to choose from
    • No aftertaste or odor


    • Not for everyday use
    • Difficult to suck water through straw

2. GRAYL Ultralight Water Purifier Bottle

GRAYL Ultralight Water Purifier Filter Bottle

What we truly appreciate about the GRAYL water bottle is how simple and cool the design is. It's extremely lightweight and easy to use for filtration.

All it takes is one press to purify and filter the water, no matter where it came from. It doesn't use any form of chemicals and batteries, so you can filter your water anytime and anywhere.

It removes pathogens and viruses that are deemed harmful for your system. Plus, it only takes a minute to filter up to two liters of water. The bottle can last for a long period of time and can remove almost all forms of bacteria, leaving no odor or taste.

With its effective filtration, it's definitely something we would recommend when out of town and always traveling!


    • Only takes a minute to filter
    • Lightweight and durable body
    • Simple but cute design
    • Takes push of a filter for a clean drinking water
    • No aftertaste or odor


    • Need to put a considerable amount of pressure when pressing the filter 
    • Difficult to separate the inner compartment for cleaning.
    • The water trapped at the bottom adds to the weight of this bottle.

3. Seychelle Water Bottle With Filtration System

Seychalle Water Bottle With Filtration System

Seychelle offers a filtered water bottle that helps remove bacteria, radio-logical and nuclear contaminants that harm your body. It has a very simple design that can take in 28 ounces (approx 800 ml) of water. It only takes less than a minute to filter, getting rid of any dirt or contaminants no matter where you are.

It has a lightweight body made out of FDA-approved polyethylene, BPA-free and leak-proof. It's also very easy to use and drink. You just need to remove the sticker at the bottom, give it a nice squeeze and sip the filtered water as it comes through the straw. Plus, it comes at an affordable price well worth the features it comes with.

Although, I believe they could have done better with the design aspect of this bottle since the current design isn't appealing at all.

All in all, I believe this bottle is suitable to prepare for disasters or for emergency and survival.


    • Ideal for camping, hunting and sports.
    • Made out of BPA-Free materials
    • Leak-proof
    • Filters water in less than a minute


    • I am not a big fan of its design
    • Leaves a bit of an aftertaste- slightly salty water
    • It might be a bit confusing to use at first

Best Pitcher Water Filter

Let's be honest, we all love chilled water and it feels like a Godsent in summer.

To have cold, filtered water, you can use a pitcher filter. Not only is it easy to use, but it's also more affordable compared to getting a whole filtration system.

It's ideal during dinners where you want clean water on the table immediately, or for those who prefer cold water from the fridge. It automatically filters the water and allows it to stay clean, despite it sitting in the fridge for long periods of time.

Here are our top three choices:

1. Aquagear Water Filter Pitcher

Aquagear Water Filter Pitcher

Aquagear offers a water filter pitcher that can purify your water from fluoride, lead, chloramine, chromium, and other types of harmful chemicals that other filters might overlook. It makes sure that it removes all harmful contaminants while still preserving healthy ones such as calcium and magnesium.

What's great about this pitcher is that it has TRIPLE capacity filters that can produce up to 150 gallons of water, which is up to four times more durable than any other pitchers. You get to save a lot of money that way! It's made for durability and sustainability, keeping you and your family healthy.

Made out of BPA-free and durable materials, you can actually feel the difference in the water you drink after being filtered through this pitcher.

    • Easy to setup and use
    • Water remains crystal clear while in the pitcher


    • It would help if it had an indicator for filter replacement
    • The plastic flap at the pour spout sometimes gets stuck making the water pour through the little gaps

2. Invigorated Living pH RESTORE Alkaline Water Pitcher

pH RESTORE Alkaline Water Pitcher Ionizer

We really love how this pitcher comes in a thinner body so it will be able to fit into the side shelves of any fridge. The pitcher itself has a clear and clean design making it easy to track how much water is left and its process when filtering water.

The filtration system itself has a multi-stage process to remove all types of particles and harmful chemicals found in water in order to make it safe to consume. It not only purifies, but also removes traces of chlorine and heavy chemicals.

You can expect around 250 gallons of purified water per filter. The pH levels are influenced by the water in your locality.​

You can get the water straight from the faucet and the pitcher can easily filter it within hours. And since it comes in a durable body and two lifelong filters, you're assured a water pitcher to last for a long period of time.


    • Easy to refill the pitcher, thanks to the flap on the lid.
    • It also filters fluoride.
    • Removes any free radicals, chemicals and toxins quickly
    • Strong and durable body which doesn't take up a lot of space.


    • Some of the customers have noticed a weird grey buildup at the bottom after a few months of usage.
    • The filter becomes clogged sometimes which requires its removal and a bit of shaking and knocking to unclog it.

3. PUR 18-Cup Water Filtration Dispenser

PUR Water Filtration Dispenser

If you're looking for something similar to a pitcher you can add to your fridge or as a standalone to produce a great amount of water, then PUR water filtration dispenser is the ideal choice.

This water dispenser can take almost five liters of water, with one filter providing forty gallons of crystal water safe for consuming. That's about two months worth of water for a substantially-sized household.

What's nice about the design is that not only can you easily get water because of its dispensing body, but it can optimize fridge space while still being lightweight and easy to refill.

Its performance is excellent, as it removes up to 96% of Mercury and other pollutants while keeping it odor-free with no aftertaste. All in all, it's a great buy for those who want chilled water in a dispenser design.


    • Practical dispenser-style body for fridge use
    • Lightweight and easy to carry for refilling
    • Holds about five liters of clean water
    • Removes pollutants efficiently
    • The water tastes way better when we compared it with another filter


    • Not necessarily a con, but you should ensure that you have enough space in your fridge because this is bigger than a traditional pitcher filter.
    • The bottom of this dispenser could have been made as a slope instead of being completely flat which causes some water to be trapped at the bottom.

Best Whole House Water Filter

For large households and people who want their entire home to have filtered water to be assured of clean drinking and washing water all around, then a whole house filter is an excellent choice.

A whole house filter will provide clean filtered water in EVERY faucet or shower, making it better for those who want assurance of filtered water all throughout their household. It saves the hassle of only using individual faucets when getting filtered water.

While it might be a bit difficult to setup (and expensive!), it's an ideal solution for large households and for those who want to save time and effort getting clean water when at home.

Here are our three whole house water filter reviews you can check out:

This whole house filtration system is made out of non-corrosive stainless steel, making it very sturdy to use for years to come. It has a carbon filter so it would not only get rid of bacteria, but to also remove chlorine, making your water taste and smell better.

iSpring WGB32B 3 Stage Whole House Water Filtration System

iSpring offers two types of filtration: Fine Sediment and Carbon, or Iron and Manganese Removal. This review focuses more on the former.

It can help with producing water supply for your WHOLE home without hassle. It can remove 95% of all types of bacteria hand harmful chemicals, leaving your home's water supply clean and ready to use anytime.

    • The blue filters might leak sometimes. So we suggest you put something on the rubber seal to lube them up.

Best Under Sink Water Filter

An under sink water system is similar to a water faucet system, though they are installed under the sink for discretion. Just like how the name implies, you install it under the sink, usually inside counter cabinets. It will help filter out bathroom or kitchen faucet water without any hassles.

This type of water filtration system is ideal for those who want to save up on space and have their kitchen (or bathrooms) look better by installing the water system underneath for no one to see or bump into. Plus, these under sink water filters are easy to install and maintain if ever you'll need to adjust it.

Read on to find our top three under sink water filter reviews:

1. Aquasana AQ-5300.55 5-Stage Under Sink Water Filter System

Aquasana AQ 5300.55 3 Stage Under Sink Water Filter System

Aquasana is one of the top leading brands of water filtration systems, with quality products built with equally durable material. Their under sink water filter system offers excellent performance and comes with a metal faucet as well. You can choose between three different faucets with or without expert installation.

While you'll be able to do the installation yourself, it's better to have an expert do it, or to have knowledge in plumbing prior to the installation.

Once installed, you'll be able to enjoy up to 600 gallons of water per filter. It removes up to 99% of contaminants, making your water taste and feel better. Plus, at a reasonable price, it's worth checking out!


    • ​It effectively gets rid of chloramines.
    • Clean, filtered water at an affordable price.
    • The filters are easy to change.
    • No odor or aftertaste in the filtered water.
    • Easy to install if you have basic plumbing knowledge


    • The filters do beep when its time for a replacement, but this is based on time, not on actual usage. So its better to keep a log.
    • We noticed that this is slow filling. So it will take a few seconds to completely fill a glass of water when compared to a tap.
    • No replacement O-rings available from the company.

2. APEC WFS-1000 Super Capacity Premium Quality 3-Stage Under Sink Water Filter System

APEC WFS 1000 3 Stage Under Sink Water Filter System

What's great about this water filter system is how it comes with a sleek white body with three canisters to last for a long period of time. APEC offers one of the supreme quality filter systems to help remove three of the major issues unfiltered water has: Chemicals, taste, and bad odor.

The package also comes with a lead-free Chrome faucet to install on your kitchen countertop, along with the safe and quality tubing for installation.

It's very easy to install as long as you follow the instructions well. Just make sure to let the water flow before using it, as it may look cloudy at first. But besides that, it has excellent features that make it a good purchase.


    • Very easy to setup and install.
    • Water tastes good and the pressure is great.
    • The filters are easy to replace and last easily for an year.
    • Build quality is good. The faucet supplied feels premium.

    • Doesn't get rid of sodium
    • It has the same type of filters in stages 2 and 3. They could have used another type of filter in stage 3.

3. CuZn UC-200 Under Counter Water Filter

CuZn UC 200 Under Counter Water Filter

The one thing I want to feature about the CuZn Under Counter Water Filter is how it can last for a long period of time. It has a 500,000 gallon capacity, which should be good for up to five years for adequately-sized families.

It has the essential three-stage system to fully get rid of ALL chemicals and contaminants, giving clean water without compromising the taste.

Another plus is how it's very easy to install without the need for a third faucet. It would only take about half an hour as long as you have the adjustable wrench and follow the instructions.

It's a bit more expensive than the other under sink water filters I reviewed, but it's well worth the price for those who prefer a water system which is easy to install and efficient in filtering water. Plus, with just ONE canister, it has a fairly large capacity!

The only deterrent​ is the look and design of this filter which certainly isn't appealing and won't go well if you have other "premium" stuffs in your kitchen.


    • The installation process is very easy.
    • The flow rate is good.
    • Working flawlessly since the last two years of our use.
    • It's durable and easy to maintain.
    • No leaks noticed so far.


    • Its fairly heavy for its size
    • Doesn't score well in the design department. But can be ignored since it is meant to be installed under the sink.

Best Countertop Water Filter

While we have the under sink water filter, a countertop water filter is installed on top of counters and usually beside the faucet itself. These are best suited for those who want something simple to install and maintain. Just like effective water filtration systems, as longs you choose the right one, you'll be able to have filtered water without the problems.

What's great about countertop water filters is that it's less expensive than other types of water filters for faucets and you can easily access it for adjusting or repairing when needed. BUT, you might bump into it easily and it doesn't look very sleek if you're keen on your kitchen's design.

1. Big Berkey BK4X2 Countertop Water Filter System

Big Berkey BK4X2 Countertop Water Filter System

Big Berkey offers a stainless steel housing, so it looks excellent when displayed. It's different from the other types of water filters because of its unique design. It comes with two filter elements that can each last for 3,000 gallons, so about a month of filtered and purified water.

The system can hold up to 2.25 gallons of water, making it a great option for small to medium households. It's versatile and meant for either beside your faucet or when traveling out in your RV and in need of purified water.

It might be a bit on the expensive side, but with its performance, versatility and stainless steel design, it deserves a spot in our list of the best countertop water filter systems.

While the body might be a bit bulky, it's still easy to transport. You can travel with it to use on any other faucets outside your home, or different faucets and showers inside different rooms of your house. We recommend you get it with the outer casing which makes it look great,

We highly recommend this water filter for day scholars and travelers or those who are constantly on-the-go and prefer not to permanently install their water filters.


    • Its portable nature makes it ideal for travelers or motorhomes
    • Fits almost any type of faucet
    • The setup takes less than a minute.

A faucet water filter doesn't come in tubes or containers as compared to under sink or countertop water filters. Instead, it's a small device you install on the faucet nozzle itself for it to stream out filtered water with ease.

What makes a faucet filter very beneficial is the fact that it's very small and lightweight. It also won't be such as hassle to install into your plumbing system, since you will only be adding it onto the faucet. Plus, it looks discreet and saves a lot of space.

1. PUR 3-Stage Horizontal Water Filtration Faucet

PUR 3 Stage Horizontal Water Filtration Faucet FM 9400B

The first thing you notice about this faucet filtration system is its sleek chrome design. You can choose between five different designs.

It has a modern body, making it match your kitchen sink without the bulkiness. The three-stage filter makes sure to purify your water and get rid of as much contaminants as possible.

The filter comes with a life indicator to keep track of how much water was used and how long the filter can last for. It can provide up to 100 gallons, or about two to three months of clean water. We have been using it since the last three years and we haven't noticed any issues of leakage or filter displacement.

You just need to watch the on/off switch while doing dishes because you might accidentally trigger it.

If you are ordering one, then please make sure you get a metal aerator instead of the default plastic aerator. You can easily contact the manufacturers and get a replacement aerator for free if you don't already have a metal aerator out of the box.


    • Offers two to three months of clean water supply
    • Has a life indicator and on/off switch. Makes it easy to switch from filtered to non filtered water.
    • It is durable and long lasting.
    • Installation is easy, provided you follow the instructions.


    • We feel the water flow is somewhat restricted in our unit. But it is supposedly fixed in the newer units.
    • The plastic aerator which was originally supplied is a big deterrent. Make sure you replace it with the new metal aerator if you have or get the old one delivered by mistake.
    • The grip has a room for improvement.

2. Culligan FM-25 Faucet Mount Filter with Advanced Water Filtration

Culligan FM 25 Faucet Mount Filter

Another sleekly designed faucet filter, Culligan has a compact design with a plotted chrome finish that makes it easy to install and use. You won't need any sophisticated tools to set it up. Simply pull the diverter tab (the small chrome switch) to enjoy filtered water!

Once your water is filtered, you'll notice a better taste and without any odor. It's said to soften water as well. At an affordable price and with a two year warranty, I would recommend this for anyone on a budget and want a good-looking faucet water filter.

Similar to the PUR faucet filter above, this one also has a trigger for the filtration process, but the uniqueness lies in its auto-off functionality. The diverter tab automatically retracts to its original position when you close the tab.

This product lacks an indicator for filter replacement, but its not that hard to figure out. Overtime, you can easily tell when the filter needs replacement taking the flow rate of filtered water in account. If it takes more than 10 seconds for 8 oz, then it's time for a replacement filter.​


    • It's really easy to install. You can enjoy filtered water in less than 5 minutes.
    • It improves the flavor and eliminates any chlorine odor from water.
    • The diverter tab retracts automatically once the tap is turned off.

We just love the water pressure this filter provides.​ You can also run hot water (up to 170 degrees Fahrenheit) through this filter.

Installation might be a little difficult for those without any prior plumbing knowledge. It's best to take help from a handyman. Make sure you determine the size of your faucet or take help from the manufacturers if you aren't sure.

Using clean and filtered water will give you the smooth and healthy skin and hair you deserve. That's why a shower water filter is also another ideal choice for those who want clean water in individual bathrooms or showers.

Best Reverse Osmosis Water Filter

Like what I mentioned above, a reverse osmosis water filter uses the latest technology in order to not only reduce the bacteria in water, but to soften it as well.

Reverse osmosis water filters are ideal for those who suffer from hard water around their area, making it difficult to consume, wash their body and other household items. Plus, it enhances its texture and flavor when drinking, making it a healthier choice.

It saves you a lot of money in the long run from purchasing bottled water or having a higher risk of getting infected or ruining your washed clothes or utensils with hard water.

Although reverse osmosis filter systems are a great way to purify water, the amount of water which is sent down the drain (referred to as reject or waste water) might be deterring. ​Most of these systems follow the 1:3 ratio which means for every one gallon of pure water, there's three gallons of waste water.

These reverse osmosis water filter reviews will help you choose what you need for your home:

1. APEC Top Tier 5-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System
