Berkey Countertop Water Filter: Complete Review
What Is Berkey?
Berkey water filters are gravity-fed purification systems that have been trusted for decades. These stainless steel units use proprietary Black Berkey purification elements to remove contaminants without requiring electricity or water pressure.
Berkey Filtration Technology
Berkey systems use a unique gravity filtration method:
Black Berkey Purification Elements These proprietary filter elements combine multiple media types including activated carbon, ion exchange, and microfiltration. Water passes through these elements via gravity, which removes bacteria, viruses, heavy metals, and chemicals.
Optional Fluoride Filters Berkey offers additional PF-2 fluoride filters that attach to the Black Berkey elements for enhanced fluoride and arsenic removal.
The filtration process relies entirely on gravity – you pour water into the upper chamber, and it slowly filters down to the lower chamber where clean water is stored.

Common Questions About Countertop Water Filters
Do countertop water filters remove fluoride?
Fluoride removal capability varies significantly by system type. Reverse osmosis systems like AquaTru remove 95-99% of fluoride effectively. Berkey systems require the addition of optional PF-2 fluoride filters to achieve 95%+ fluoride removal. Standard activated carbon filters like Pureal typically remove only 40-70% of fluoride.
If fluoride removal is a priority, either choose a reverse osmosis system or ensure your gravity filter includes specialized fluoride reduction elements.
How often should I change countertop water filter cartridges?
Filter replacement frequency depends on the system and your water consumption:
- AquaTru: Pre-filters every 6-12 months, RO membrane every 2 years, VOC filter every 12-24 months
- Berkey: Black Berkey elements every 6,000 gallons (typically 5-6 years for average household)
- Pureal: Every 6-12 months depending on usage and water quality
Most systems include indicators or reminders. Always follow manufacturer recommendations for your specific model.
Are countertop water filters better than pitcher filters?
Yes, countertop water filters generally provide superior filtration compared to pitcher filters. Countertop systems offer more comprehensive contaminant removal, higher capacity, longer filter life, and better overall value despite higher initial costs.
Pitcher filters primarily remove chlorine, taste, and odor issues but struggle with dissolved solids, fluoride, heavy metals, and many other contaminants that countertop systems effectively eliminate.
Can I use well water with countertop filters?
Yes, but with important considerations. Well water often contains higher sediment levels, bacteria, and dissolved minerals that can shorten filter life or overwhelm certain systems.
Berkey systems excel with well water and untreated sources. AquaTru can handle well water but may require more frequent pre-filter changes. For any system, consider getting your well water tested first to understand what contaminants need removal.
Some well water conditions may require pre-treatment before using countertop filters.
Do countertop water filters waste water?
This depends on the filtration technology:
- Reverse osmosis systems (AquaTru): Yes, RO systems produce wastewater (typically 2-3 gallons wasted per gallon filtered) as part of the purification process
- Gravity filters (Berkey, Pureal): No wastewater produced – all water added is filtered and available for use
If water conservation is a priority, gravity-fed systems are more efficient, though RO systems provide more thorough filtration.
Conclusion: Making Your Final Decision
Clean, safe drinking water is essential for your health and wellbeing. The good news is that all three countertop water filters reviewed here – AquaTru, Berkey, and Pureal – provide significantly better water quality than tap water alone.
The Bottom Line:
- AquaTru delivers the most comprehensive contaminant removal with convenient, automated operation. It’s the best choice for those who want maximum purification and don’t mind higher costs.
- Berkey offers exceptional long-term value, off-grid capability, and nearly indestructible construction. It’s ideal for families, preppers, and anyone wanting a buy-it-for-life system that works without electricity.
- Pureal provides solid mid-range performance at an accessible price point. It’s perfect for budget-conscious buyers who want better filtration than pitchers but don’t need industrial-strength purification.
Consider your specific needs: budget, space, contaminant concerns, daily water consumption, and whether you need off-grid capability. Any of these three systems will dramatically improve your water quality compared to unfiltered tap water.

FAQs About Best Countertop Water Filters Review
1. Can countertop water filters remove all contaminants from tap water?
No filter removes 100% of all contaminants, but high-quality countertop systems remove 95-99% of most common pollutants. Reverse osmosis systems like AquaTru offer the most comprehensive removal, eliminating virtually all dissolved solids, heavy metals, chemicals, and microorganisms. Gravity filters like Berkey are also highly effective against a broad spectrum of contaminants. The key is matching your filter choice to your specific water quality concerns and getting your water tested if you have particular contamination worries.
2. Will a countertop water filter improve the taste of my tap water?
Absolutely. One of the most noticeable benefits of countertop filtration is dramatically improved taste and odor. These systems remove chlorine (the primary cause of chemical taste), organic compounds, and other substances that affect water flavor. Most users report that filtered water tastes significantly cleaner, fresher, and more pleasant than tap water. The activated carbon stages in all three systems reviewed specifically target taste and odor issues, making even poor-tasting municipal water enjoyable to drink.
3. How much money can I save by using a countertop filter instead of buying bottled water?
The savings are substantial. An average family spending $600-$1,200 annually on bottled water can recover their countertop filter investment within 6-12 months. Over five years, a Berkey system saves $2,500-$5,000 compared to bottled water while reducing plastic waste. Even with higher operating costs, AquaTru saves $2,000-$4,000 over the same period. Beyond financial savings, you’ll eliminate the hassle of purchasing, transporting, and storing heavy bottled water while significantly reducing your environmental footprint.
4. Do countertop water filters remove beneficial minerals from drinking water?
Reverse osmosis systems like AquaTru do remove most minerals along with contaminants, though you can add a remineralization filter. Gravity systems like Berkey and Pureal retain more beneficial minerals while removing harmful substances. However, research shows most people get adequate minerals from food, making mineral removal in water less concerning than many believe. If mineral content is important to you, choose a gravity-fed system or add a remineralization stage to your RO system.
5. Are countertop water filters difficult to maintain or time-consuming?
Not at all. Maintenance is straightforward for all three systems. AquaTru requires minimal effort – just add water and replace filters as indicated (10-15 minutes per filter change). Berkey needs periodic cleaning of the elements (15-20 minutes every few months) and filter replacement every few years. Pureal falls in between. None require professional service, special tools, or technical expertise. Monthly time investment is typically less than 30 minutes for any system – far less effort than shopping for and handling bottled water.
