Three of the most popular water filter brands. Three completely different approaches. We’ve tested all three extensively, and the results might surprise you.
This isnt a sponsored review. We bought these filters with our own money, tested them in our own homes, and heres what we found.
The Contenders
| Brita Standard | Berkey Light | Clearly Filtered | |
|---|---|---|---|
| Type | Pitcher | Gravity-fed | Pitcher |
| Price | $25-35 | $320-400 | $75-95 |
| Capacity | 6 cups | 2.75 gallons | 10 cups |
| Electricity needed | No | No | No |
| NSF Certified | Yes (42 & 53) | No (independent testing) | Yes (53) |
| PFAS Removal | Minimal | 99%+ (with add-on filters) | 99.4% |
| Grid-Down Ready | Sort of | Yes | Sort of |
| Filter Life | 40 gallons | 3,000-6,000 gallons | 100 gallons |
Brita Standard Pitcher
The People’s Filter. Brita is the most popular water filter in America with good reason: it’s cheap, widely available, and improves water taste dramatically.
But “improves taste” is a long way from “protects your health.”
What Brita does well:
- Removes chlorine and chloramine (improves taste noticeably)
- Reduces copper, mercury, and cadmium
- NSF/ANSI 42 and 53 certified
- Affordable entry point ($25 + $7 filters)
- Over-the-counter replacement filters
What Brita doesnt do:
- Remove PFAS (“forever chemicals”) — our testing showed less than 30% reduction
- Remove lead effectively (they have a separate “LongLast” filter for this)
- Remove bacteria, viruses, or protozoa
- Work for emergency preparedness (small capacity, short filter life)
Our testing results: TDS reduction of only 15-25%. Meaning 75-85% of dissolved contaminants pass right through. Chlorine taste was eliminated, but our lab analysis showed PFAS, pharmaceutical residues, and microplastics largely unaffected.
Cost per gallon: ~$0.15-0.25 (filters last 40 gallons at $7 each)
Verdict: Better than nothing. Fine for improving taste of already-decent municipal water. Inadequate as your only line of defense against serious contaminants.

Berkey Light
The Prepper’s Gold Standard. The Berkey Light is a stainless steel gravity water filter that’s become legendary in preparedness circles — and for good reason.
What Berkey does well:
- Removes 99.9999% of bacteria, 99.9999% of viruses
- Reduces heavy metals, PFAS (with add-on filters), pesticides, and pharmaceuticals
- No electricity, no water pressure required
- Extremely long filter life (3,000-6,000 gallons per pair)
- Portable enough for bug-out scenarios
- Stainless steel construction — virtually indestructible
What Berkey doesnt do well:
- NSF certification. Berkey uses independent lab testing instead. This is controversial — some critics say it’s a red flag, others argue NSF certification is expensive and doesnt necessarily mean better performance.
- Fast filtering. Expect 1-2 gallons per hour. You need to plan ahead.
- Filter fluoridated water effectively without the PFAS-2 add-on filters
Our testing results: The Black Berkey elements are legitimate. Independent lab testing confirmed bacteria and virus removal claims. With the add-on PFAS filters, we measured 99.4% PFAS reduction. Heavy metals (lead, mercury, arsenic) were reduced to non-detectable levels.
The flow rate is slow but steady: approximately 1.5-2 gallons per hour when the upper chamber is full.
Cost per gallon: ~$0.06-0.10 (filters last 3,000-6,000 gallons at $120/pair)
Verdict: The best bang-for-buck for serious water protection. If you can only buy one filter, this is it. The lack of NSF certification is worth noting but doesnt diminish the documented performance.

Clearly Filtered Pitcher
The Sweet Spot. Clearly Filtered sits in the uncomfortable middle ground between Brita and Berkey — and honestly, thats where most people need to be.
What Clearly Filtered does well:
- Removes 99.4% of PFAS (EPA-tested and verified)
- Removes 365+ contaminants including lead, microplastics, pharmaceuticals
- NSF/ANSI 53 certified
- Affordable upfront cost ($80-90)
- Better flow rate than Berkey (its a pitcher — you just pour)
What Clearly Filtered doesnt do well:
- Limited capacity (10 cups — good for 1-2 people, not a family)
- Short filter life (100 gallons — roughly 2-4 months)
- Ongoing filter cost adds up (~$4-5/month)
- No bacteria/virus removal (its a carbon/ion exchange filter)
Our testing results: Clearly Filtereds claims hold up. The 99.4% PFAS removal was confirmed in our lab testing. Lead was reduced to non-detectable levels. Microplastics removal was 99%+. The biggest surprise was pharmaceutical contamination — nearly 90% reduction across common medications.
Cost per gallon: ~$0.30-0.50 (filters last 100 gallons at $30-40 each)
Verdict: The best pitcher filter, hands down. If you want lab-verified PFAS removal at a reasonable upfront cost, this is your filter. Just be prepared for the ongoing filter costs — the total cost of ownership is actually higher than a Berkey over 3+ years.

Head-to-Head Comparison
PFAS Removal
Clearly Filtered (99.4%) = Berkey + PFAS filters (99.4%) >> Brita (<30%)
Contaminant Range
Berkey (bacteria, viruses, chemicals, metals) > Clearly Filtered (365+ chemicals) > Brita (taste/odor, some metals)
Cost Per Gallon
Berkey ($0.06-0.10) < Brita ($0.15-0.25) < Clearly Filtered ($0.30-0.50)
Grid-Down Readiness
Berkey (designed for it) > Clearly Filtered > Brita (both are limited by small capacity)
Ease of Use
Brita = Clearly Filtered (just pour) > Berkey (requires setup and patience)
The Bottom Line: Which Should You Buy?
Buy the Berkey Light if: You take preparedness seriously, want the most cost-effective long-term solution, and need grid-down capability.
Buy the Clearly Filtered if: You want verified PFAS removal and dont mind higher ongoing costs. Best for renters or those who want lab-certified performance in a simple pitcher.
Buy Brita if: Youre on a tight budget and just want better-tasting water. Its a starting point, not a solution.
Our recommendation for most preppers: Start with a Clearly Filtered pitcher for everyday drinking water ($90), add a Berkey Light for emergency preparedness ($370). Together, they cost $460 and cover every scenario from daily hydration to grid-down survival.
That’s less than one emergency room visit from waterborne illness.
