Honest Waterdrop Water Filter Review 2025 (G3P600)
Last Updated on 06/23/2025 by Kacie Barlow
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, sick of the unfiltered water, and 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 this reverse osmosis water filter/waterdrop faucet filter, 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.
Waterdrop vs. Berkey: Which Water Filter Is Better?
Like I mentioned, I seriously considered the Berkey. But, ultimately, I decided on the waterdrop instead. Both are excellent water purification options, but they serve different types of households, budgets, and lifestyles.
Here’s a quick breakdown of the two:
| Feature | Waterdrop (e.g., G3 Series) | Berkey (e.g., Big Berkey) |
| Filtration Method | Reverse Osmosis (RO), multi-stage filters (carbon block, etc.) | Gravity-fed with carbon + optional fluoride filters |
| Removes Fluoride? | ✅ Yes | ✅ Yes (with additional filters) |
| Removes Heavy Metals? | ✅ Yes (lead, arsenic, etc.) | ✅ Yes |
| Removes Microorganisms? | ✅ Yes (bacteria, viruses filtered by RO membrane) | ✅ Yes (though viruses may require extra filtering time) |
| Installation | Requires under-sink plumbing + outlet | No installation; countertop setup |
| Portability | ❌ Not portable | ✅ Highly portable |
| Filter Replacement | RO membrane lasts ~2 years; others ~6–12 months | Every 3,000–6,000 gallons; every few years per family use |
| Flow Rate | Fast (fills cup or pot quickly) | Slow (gravity-fed drip system) |
| Counter Space Required | Minimal (under-sink unit) | Moderate to large countertop footprint |
| Cost | $$ to $$$ (G3 costs more upfront, but fewer replacement needs) | $$ (cheaper upfront, but filters can add up over time) |
| Taste | Clean, neutral (RO removes most flavor) | Slightly mineral-rich taste |
| Best For… | Families, cooks, serious water quality concerns | Renters, off-grid homes, preparedness-minded households |
My Take
I looked hard at the Berkey before buying the Waterdrop. While Berkey is great for off-grid use or emergencies, I needed something fast, hands-free, and that filtered out everything — including fluoride — with minimal countertop clutter. Waterdrop won out for our everyday kitchen needs and ease of use.
How to Know When to Change Your Waterdrop 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.
Waterdrop Water Filter FAQ’s
What About Waterdrop’s Fluoride Filter?
Yes, Waterdrop’s fluoride filter is built right into their multi-stage filtration system — no need to purchase an additional fluoride filter like with Berkey. This was a big deal for us since fluoride was one of the main things we wanted to remove from our water.
Does Waterdrop Make Sink Filters or Water Filter Pitchers?
Absolutely! Waterdrop offers more than just under-sink RO systems. You can also find:
- The Waterdrop water filter pitcher – great for quick filtering, fridge storage, or as a backup.
- A sink filter (like the Waterdrop Flo Faucet Filter) – perfect for renters or budget-friendly filtering.
- A refrigerator water filter for select fridge brands.
- Even whole-house filters for advanced setups.
And if you need a compact countertop filter, a dispenser model, or full-home filtration, Waterdrop has a large capacity, efficient filtration option for you either way.
Most Waterdrop systems include a filter life indicator and use color-coded systems to tell you when it’s time for a change.
Here’s a quick breakdown:
- Pre-sediment filter: 6 months
- Carbon block filter: 12 months
- RO membrane: 24 months
- Post-carbon filter: 12 months
This long lifespan means fewer filter changes, saving both time and money. If you ever have a quality issue, Waterdrop’s support is helpful and responsive from what I’ve gathered from the reviews (although, I haven’t actually had any first-hand experience with their customer service).
Why Did You Choose the G3 Model and Not a Newer One?
I did consider a newer model, but I chose the G3 because it had solid reviews, was in stock in early January, and had a reasonable price for everything included. It’s still one of the most popular models and fit our needs perfectly.
How Fast Is Waterdrop’s Delivery Time?
When I ordered my Waterdrop system, I was pleasantly surprised at how quickly it arrived. It came in its original packaging, was well-protected, and showed up within just a few days — even without expedited shipping. Based on my experience and what I’ve seen in online reviews, delivery time is one of the brand’s strong points.
While I haven’t had to reach out to customer service personally (which is a good thing, right?), many reviewers mention that Waterdrop’s customer support is responsive and helpful — especially if you run into installation questions or need a part replaced.
If you’re ordering through online retailers like Amazon or Waterdrop’s official site, you’ll also benefit from tracking updates and solid return policies, just in case anything goes wrong in transit.
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.
