Like many of you, I never gave much thought to what was in my tap water – until I became a mum and started researching the effects of fluoride, PFAS, and microplastics. That journey completely changed my life, leading me to a career in the water filtration industry. Now, I’m passionate about helping families find the best solutions for clean, safe drinking water.
If you’re wondering which countertop water filter removes the most contaminants, you’re not alone. With so many options out there, it can be overwhelming. But don’t worry, I’ve done the research (and the trial and error!) so you don’t have to.
What Water Filter Takes Out the Most Contaminants?
Not all water filters are created equal. Some are great at removing chlorine and bad tastes, while others go further, eliminating heavy metals, fluoride, PFAS (forever chemicals), and even microplastics. Here’s what to look for:
Reverse Osmosis (RO) Water Filters are some of the most effective systems, removing up to 99% of contaminants, including fluoride, lead, arsenic, and PFAS. However, traditional RO systems are usually installed under the sink and can waste water. Luckily, there are now countertop RO water filters that offer similar filtration without the complicated installation.
Benchtop Water Purifiers with Advanced Filtration—If you want a high-performing countertop system, look for one with multiple filtration stages, including activated carbon, ion exchange, and ceramic filters. The best models remove chlorine, heavy metals, pesticides, and even some pharmaceuticals.
PFAS Water Filters—PFAS chemicals (found in non-stick cookware, firefighting foam, and more) are notoriously difficult to remove. Only certain filters with certified activated carbon or ion exchange resins can effectively reduce them.

What is the Best Countertop Water Filtration System?
After testing multiple systems, here are my top picks for efficiency and convenience:
1. Reverse Osmosis Countertop Filters
If you want the gold standard in filtration, a countertop RO system is hard to beat. It removes fluoride, lead, arsenic, and other heavy metals, PFAS, Microplastics and pharmaceuticals.
The only downside is that RO systems can remove some beneficial minerals, so consider a model with a remineralisation cartridge to add back calcium and magnesium.
2. Multi-Stage Benchtop Water Purifiers
For those who want great filtration without the complexity of RO, a multi-stage benchtop purifier is an excellent choice. Look for:
– Activated carbon (removes chlorine, pesticides, and bad tastes)
– KDF media (reduces heavy metals and inhibits bacteria)
– Ion exchange resin (targets fluoride and PFAS) These systems are perfect for everyday use and require minimal maintenance, just filter replacements every few months.
3. Gravity-Fed Ceramic Filters
If you prefer a no-electricity, chemical-free option, ceramic gravity filters are a solid choice. They’re great for removing bacteria, sediment, and some heavy metals, though they may not be as effective against fluoride or PFAS unless paired with additional filtration.
For the broadest contaminant removal, I recommend a countertop RO system or a high-quality benchtop water purifier with independent certifications (like NSF/ANSI standards).
Why We Use a Whole House Filter + Countertop Purifier
In our home, we use a whole house water filter to remove chlorine, sediment, and other irritants. This has been a game-changer for our child, who used to suffer from dry skin and eczema. Chlorine in shower water was a big trigger!
However, since whole house filters don’t remove fluoride, we also use a benchtop water purifier for drinking and cooking water. This combo ensures every drop of water in our home is as clean as possible.
The Best Countertop Water Filter for Clean and Safe Water
If you’re looking for the most efficient countertop water filter, I’d recommend either a countertop RO system or a multi-stage benchtop purifier with certifications for PFAS, fluoride, and heavy metal removal.
As a mum who’s been through the research (and seen the benefits firsthand), I can’t stress enough how much cleaner, safer water has improved our family’s health. If you have any questions, feel free to reach out—I’m always happy to help!
