Honest Waterdrop Water Filter Review 2025 (G3P600)
So, you’re thinking about jumping into the clean water movement and you’re curious about the Waterdrop water filter? I was right where you were, doing all the research I could on the best water filters for my family.
If you’re like me, you don’t trust tap water straight out of the municipal water supply (And honestly, how could we?) There are all kinds of harmful contaminants floating around—heavy metals, volatile organic compounds, and who knows what else. So, after way too much time researching water purification products, I finally got my hands on a Waterdrop Filter, and here’s what I really think about it.
(If you’re anything like my husband and you want to get straight to what could be better or what to know before buying/installing, scroll down to the table of contents and skip straight to that part 😉 Otherwise, stick around for my full review)

Is Waterdrop a Good Water Filter Brand?
If you’re looking for a solid water filter brand that actually does what it claims, Waterdrop is a great option, in my opinion.
It’s one of the more well-known names in water purification products, and offers everything from reverse osmosis systems to countertop water filters, refrigerator filters, and sink filters.
I’ll be completely honest here- I really really wanted (and still do) the whole house reverse osmosis system, but it’s just not in the budget right now. However, I’ve been so very happy with the waterdrop!
And regardless of whether you’re filtering out heavy metals, volatile organic compounds, fluoride, or chlorine, Waterdrop has a system that gets the job done.

A few things that make the Waterdrop a good brand…
Does the Waterdrop Water Filter Actually Work?
Yes! The Waterdrop Water Filter gets rid of that weird water taste and filters out all the junk that doesn’t belong in my cup.
I went with the Waterdrop G3 series, which is a tankless RO system. That basically means I don’t have to deal with a bulky water tank under my sink, and I get pure water straight from the tap.

The reverse osmosis membrane in this thing is no joke—it removes heavy metals, fluoride, and all those mystery contaminants that you don’t wanna be drinking (or your family to be drinking).
The flow rate is way better than I expected. I don’t have to stand there forever waiting to fill a glass or a pitcher.
We use it for drinking water, cooking, and even water for my sourdough starter (which, by they way, my sourdough starter loves this water so much)!
What I Love About Waterdrop Water Filter


What You Should Know Before Installing the Waterdrop (According to My Husband)
Installing this system isn’t rocket science, but you’ll want some basic plumbing knowledge—or at least know someone who does. This was definitely not something I could have done on my own. I would have sent it back before I tried to install this myself.
A Few Things to Keep in Mind:
Tools You’ll Need:
The kit includes Teflon tape and most of what you need, but having the right tools on hand will make the job smoother.
What Could Be Better?
Did you notice that I never mentioned anything about quality in this “what could be better” section? That’s because I have zero complaints when it comes to performance or taste.
Sure, we had a couple set up challenges and it was definitely a financial investment (maybe not for some but for us), but once we got it installed, we have been so pleased with our purchase!
How Long Does a Waterdrop Filter Last?
The lifespan of a Waterdrop filter depends on the type of filter you’re using and how much gallons of water you run through it. Here’s a breakdown of how long different Waterdrop products typically last:
- PP filter (pre-sediment filter): ~6 months
- Carbon block filter: ~12 months
- Reverse osmosis membrane: ~2 years
- Post-carbon filter: ~12 months
One of the best features of the Waterdrop G Series (as previously mentioned) is its built-in filter life indicator, so you don’t have to guess when it’s time for a replacement.
How to Know When to Change Your Filter
- Slower flow rate – If water is taking forever to come out, your filter head might be clogged.
- Change in water taste – If your fresh water starts tasting funky, it’s time for a replacement filter.
- Filter life indicator is on – Many Waterdrop products have built-in reminders when it’s time for a filter change.
Are the Waterdrop Filters Hard to Replace?
Nope! Waterdrop filters are known for their easy installation, and swapping out a new filter usually takes just a couple of minutes.
Is It Healthy to Drink Reverse Osmosis Water?
Yes, reverse osmosis (RO) water is safe and healthy to drink, but there’s a little more to it than just a simple yes or no.
Reverse osmosis water filters are great at removing harmful contaminants like heavy metals, volatile organic compounds, chlorine, fluoride, and bacteria, making it one of the most effective water purification products out there. Trust me, I did a ton of research so you don’t have to!
The Pros of Drinking Reverse Osmosis Water
What About the Minerals?
The argument that reverse osmosis systems remove minerals sounds concerning at first, but in reality, tap and even bottled water aren’t major sources of essential minerals in the first place. Most of our calcium, magnesium, and other necessary nutrients come from food—things like leafy greens, nuts, dairy, and meats.
Even if you’re drinking non-RO filtered water, the mineral content is usually minimal, especially if you’re on municipal water, which is often treated and stripped of naturally occurring minerals anyway. Bottled water isn’t much better—it’s often just filtered tap water, and even “mineral water” typically contains only trace amounts.
Final Thoughts
If you’re worried about water quality, live in an area with high contaminants, or just want pure, great-tasting water, a reverse osmosis system is one of the best investments you can make.
Would I drink it every day? Absolutely. Would I recommend adding minerals back in? It’s optional, but not necessary. Either way, RO water is one of the cleanest, safest, and healthiest choices.
Waterdrop delivers solid filtration without the hassle—their systems are well-made, easy to use, and a good value compared to other brands. If you’re looking to upgrade your water and ditch plastic bottles, this is a smart choice.
Would I recommend it? Yep. Would I buy from them again? Without a doubt.
