The key to a healthy lifestyle is clean water. Since many Americans worry about contaminants and impurities in
their normal tap water, more of them are using advanced filtration systems to ensure their drinking water is
clean. The most popular filtration system continues to be the Waterdrop Alkaline Reverse Osmosis system due to
its reliability in purifying tap water without removing its natural minerals.
Understanding Reverse Osmosis & Alkaline Water
Reverse osmosis is a type of water purification method where water is forced through a semi-permeable
membrane to remove most contaminants, including heavy metals, fluoride, lead, and chlorine. When the water comes
out on the other side of the membrane, it is clean, drinkable water without these impurities.
Alkaline water is water with a high pH level compared to ordinary tap water. That means it is rich in
essential minerals, such as magnesium and calcium. Regularly drinking alkaline water will lower your body’s
acidic levels and keep you well-hydrated and healthy overall. The Waterdrop line of
alkaline water filter systems offers the fastest and most convenient way to
convert tap water into purified water rich in minerals.

How to Choose the Right Waterdrop RO System?
When you’re searching for the perfect Waterdrop
Reverse Osmosis system , consider the specific water consumption needs in
your household. Only then can you make a well-informed decision about which Waterdrop model is best for your
household.
Let’s look at some tips on how you can come to this decision:
Household Water Consumption
Do you have a household with a large family living there? If so, you probably have lots of people using water on
a daily basis. In that case, you need a reverse osmosis system with a high flow rate to deliver clean water
quickly whenever someone needs it.
-
G5P700 & G5P700A : These models boast a high flow rate of 700 gallons per day (GPD), making
them suitable for households that require a substantial amount of purified water daily.
-
G5P500 & G5P500A : With a flow rate of 500 GPD, these systems are ideal for smaller
households or those with moderate water consumption.
Preference for Mineral-Rich Alkaline Water
Do you want to consume alkaline water to enjoy its rich amount of essential minerals and delicious taste? If so,
you’ll need a Waterdrop water filtration system with alkaline mineralization capabilities.
-
G5P500A & G5P700A : Both models include an alkaline filter that adds essential minerals like
calcium, magnesium, sodium, and potassium, enhancing the taste and potential health benefits of your
drinking water.
-
G5P500 & G5P700 : These models provide thorough purification without the addition of
minerals, resulting in pure RO water.
Waterdrop
reverse osmosis remineralization systems are also designed to restore
essential minerals like calcium, magnesium, sodium, and potassium to your drinking water, enhancing both taste
and potential health benefits.
Desire for Smart Features
Most people want water filtration systems with the latest technological features, such as real-time monitoring,
for more user convenience and satisfaction.
The G5P700 and G5P700A models have some great modern technological features, such as a smart faucet display
showing real-time data regarding the filter life and total dissolved solids (TDS) levels. This information will
let you know when your filtration system needs a new filter and other maintenance.
The G5P500 and G5P500A models don’t feature any smart display technology, but you can still enjoy its
high-quality water purification technology.
Budget Considerations
The best thing to do is choose a reverse osmosis filtration model with a balance between affordability and
features.
For instance, the G5P500 model has a price tag of $239.99. It is one of the more affordable models while still
giving you a great reverse osmosis filtration experience to suit your general water purification needs.
However, for only $10 more, you can purchase the G5P500A for $249.99 and enjoy the added benefit of having an
alkaline mineralization feature and extra smart technological features.
The G5P700 model is priced at $349.99. If you are willing to pay this much higher price, you can enjoy a much
higher flow rate to accommodate larger households. It also comes with smart technological features, too.
Alternatively, for $10 more, you can purchase the G5P700A model for $359.99 and receive all the best features
you would ever want from a reverse osmosis filtration system. It comes with a high flow rate, smart monitoring,
and alkaline mineralization features in one comprehensive system.
The Comparative Advantages of the G5P700A Alkaline RO Water Filter
There is no question that the Waterdrop G5P700A Alkaline Reverse Osmosis Water Filter is the top choice due to
the following advanced features it possesses:
8-Stage Filtration System
The G5P700A model uses an 8-stage water filtration process to thoroughly remove contaminants and impurities from
water, including heavy metals, fluoride, lead, chlorine, PFOA, and PFOS. When it is finished, you will be left
with clean, purified water that is healthy and safe to drink.
Alkaline Mineralization
The G5P700A model offers alkaline mineralization, which means it adds essential minerals to your tap water as it
flows through the filter. The added minerals include potassium, sodium, calcium, and magnesium. Together, they
improve the taste of the water and make it healthier to drink.
High Flow Rate (700 GPD)
The G5P700A model offers a 700GPD flow rate, which is fast enough to provide you with six ounces of purified
water every six seconds. It is perfect for busy households with large families living in them.
2:1 Pure-to-Drain Ratio
The G5P700A model offers more efficiency and environmental friendliness, as it only wastes one gallon of water
for every two gallons of water purified.
Tankless Design
The GP5700A model has a compact design that doesn’t use a water tank. As a result, you will still have about 70%
free space underneath your sink after you install it.
Smart Faucet Display
The G5P700A model has a built-in smart faucet display showing real-time data on filter life and TDS levels. That
way, you will always know about the current quality of the filtered water.
Easy Installation and Maintenance
You can install the G5P700A system without a professional. It is designed to support do-it-yourself
installations because it comes with user-friendly instructions and everything you need to get started.
You won’t have many maintenance responsibilities since the CF water filter stays good for up to six months, and
the reverse osmosis filter stays good for up to 24 months. Then, you simply need to replace the filters to keep
the water fresh.
Who Should Consider the G5P700A?
The G5P700A model is perfect for the following consumers:
- People who care about staying healthy will love the purified water with added essential minerals
- Large families in households that need to produce a lot of purified water each day.
- Homeowners who want to have a lot of free space underneath their sink after installing the filtration
system.
- Any consumer that wants to save on water and help protect the environment.
Conclusion
Waterdrop alkaline reverse osmosis systems are the best for keeping you hydrated with purified water. You could
choose the G5P700A, G5P700, G5P500A, or G5P500 and still enjoy clean and delicious drinking water for you and
your family. The choice depends on your budget and whether you want the added benefit of alkaline mineralization
for enhanced health.
