Clearly Filtered vs Aquasana Powered Pitcher: Gravity vs Electric Filtration
Clearly Filtered and Aquasana's Clean Water Machine both claim broad contaminant removal for households worried about PFAS, lead, and chlorine byproducts in tap water, but they filter water in completely different ways. Clearly Filtered relies on gravity alone, no power required. Aquasana's pitcher uses a powered filtration cycle that pushes water through its cartridge under pressure, trading electrical dependence for a much faster fill.
Both are independently certified, both target similar contaminant lists, and both are priced in the same general range once you account for replacement filters. This guide breaks down where each pitcher actually wins: certification standards, flow rate, filter life, and 5-year cost of ownership.

Certification: Two Different Paths to the Same Claims
Clearly Filtered Certifications
Clearly Filtered's pitcher carries formal third-party certification:
- NSF/ANSI Standard 42: Chlorine taste and odor reduction, certified by NSF International.
- WQA certification to NSF/ANSI P473 protocol: PFOA and PFOS reduction, tested by the Water Quality Association using the dedicated PFAS testing standard.
- Independent IAPMO NJ (ISO 17025 accredited) lab testing: Covers lead (99.34% reduction at 152 ppb), fluoride (99.54%+), chromium-6, arsenic, and dozens of additional contaminants published in a public performance data sheet.
Aquasana Certifications
Aquasana's Clean Water Machine carries a broader certification stack for a single product:
- NSF/ANSI Standard 42: Chlorine and chloramine taste/odor reduction (97%+).
- NSF/ANSI Standard 53: Health-effects contaminants including lead (99%), mercury, and cyst reduction.
- NSF/ANSI Standard 401: Emerging contaminants including PFOA/PFOS (96%+), pharmaceuticals, herbicides, and pesticides.
- NSF/ANSI P473 protocol: The same dedicated PFAS testing standard Clearly Filtered uses, though at a slightly lower certified reduction rate.
Both products submit to accredited third-party certification, which puts them ahead of filters that rely only on company-commissioned testing. Aquasana's NSF 401 certification technically covers a wider range of emerging contaminant classes (pharmaceuticals, pesticides) that Clearly Filtered addresses through separate lab data rather than a single unified NSF standard.
Why Aquasana Needs Power (and What You Gain From It)
Clearly Filtered, like nearly every pitcher filter on the market, relies on gravity to slowly pull water through the filter cartridge. This is why gravity pitchers take 10-20 minutes to fully filter a reservoir.
Aquasana's Clean Water Machine instead uses a small internal pump to push water through its Claryum filter cartridge under pressure. This is a fundamentally different mechanism from every other pitcher in this comparison series, and it changes the practical experience of using the product. Instead of waiting 15-20 minutes for a full pitcher to filter by gravity, the Clean Water Machine delivers filtered water in seconds at the push of a button, at a rate of about 0.5 gallons per minute.
The tradeoff is that the unit must sit near an outlet, needs its docking base and reservoir assembly (which takes up more counter space than a simple gravity pitcher), and does not work at all without power. For a kitchen counter with an available outlet, this is a minor inconvenience. For camping, off-grid living, or emergency preparedness during a power outage, it is disqualifying, and Clearly Filtered is the clear choice in those scenarios.
Filter Life and Real-World Maintenance
Aquasana's filter lasts roughly 3x longer than Clearly Filtered's on a per-gallon basis: 300-320 gallons versus 100 gallons. For a household of 2-3 people drinking and cooking with 1-1.5 gallons a day, this works out to Aquasana filter changes every 5-7 months versus Clearly Filtered changes every 2-3 months.
This matters beyond convenience. Clearly Filtered's shorter filter life means more frequent purchases (roughly 3-5 filters a year versus Aquasana's 2-3), which adds up in both cost and the mental overhead of remembering to reorder before the filter is exhausted. Aquasana's flow rate also serves as a built-in reminder: as the filter nears the end of its life, the powered flow noticeably slows, giving a clear signal to reorder.
5-Year Cost Comparison
| Cost Component | Clearly Filtered Pitcher | Aquasana Clean Water Machine |
|---|---|---|
| Upfront system cost | ~$90-100 | ~$199.99 |
| Filter lifespan | 100 gallons (~2-4 months) | 300-320 gallons (~3-6 months) |
| Replacement filter cost | ~$50-60 each | ~$73.49 each |
| Filters needed over 5 years (family of 2-3, ~450 gal/yr) | ~22-23 filters | ~7-8 filters |
| 5-year filter cost | ~$1,100-1,300 | ~$515-590 |
| 5-year total cost | ~$1,190-1,400 | ~$715-790 |
| Effective cost per gallon | ~$0.50-0.60 | ~$0.30-0.35 |
Aquasana's higher upfront price is offset within roughly 18-24 months by its lower filter replacement frequency. Over a full 5-year window, Aquasana ends up cheaper per gallon despite costing more to buy, largely because each filter change replaces 3x more capacity for only about 40% more per cartridge.
Which Pitcher for Which Household
| Situation | Recommended Filter | Why |
|---|---|---|
| No outlet access near the filter location | Clearly Filtered | Gravity-only design works anywhere, no power required |
| Camping, RV, or off-grid living | Clearly Filtered | Fully functional without electricity; compact footprint |
| Emergency preparedness for power outages | Clearly Filtered | Continues working during a blackout when Aquasana cannot |
| Want the fastest possible fill time | Aquasana Clean Water Machine | 0.5 GPM powered flow vs. 15-20 minute gravity fill |
| Lowest 5-year cost per gallon | Aquasana Clean Water Machine | ~$0.30-0.35/gallon vs Clearly Filtered's ~$0.50-0.60/gallon |
| Fewest filter changes per year | Aquasana Clean Water Machine | 300-320 gallon filter life vs Clearly Filtered's 100 gallons |
| Renter or small kitchen, no counter space for docking base | Clearly Filtered | Standard pitcher shape fits any fridge shelf; no separate power base needed |
| Want independently NSF/WQA certified performance data | Tie | Both hold accredited third-party certification for PFAS, lead, and chlorine reduction |
Some households run both: Clearly Filtered as a backup for power outages or travel, with the Aquasana Clean Water Machine as the daily-use unit for its speed and lower long-term filter cost.
Real Owner Feedback
Clearly Filtered
Owners consistently cite the taste (clean, minerals retained) and confidence in the published lab data as reasons to stick with it long term. The most common complaints are the $50-60 per-filter cost and progressive slowdown in gravity flow rate as the filter approaches its 100-gallon limit, usually noticeable by month 2-3.
Aquasana Clean Water Machine
Owners frequently cite the speed (filtered water in seconds, not minutes) and the convenience of fewer filter changes as the standout benefits. The most common complaints are the counter space required for the docking base and reservoir, needing an outlet nearby, and occasional pump noise during the filtration cycle. A minority of owners report the pump motor requiring replacement after 2-3 years of daily use, which is not covered once the 1-year warranty expires.

Frequently Asked Questions
Is Clearly Filtered or Aquasana's powered pitcher better for PFAS?
Both are independently certified for PFAS reduction, but through different standards. Clearly Filtered holds WQA certification to the NSF/ANSI P473 protocol for PFOA/PFOS at 99%+. Aquasana's Clean Water Machine is NSF/ANSI 401 certified, which covers 96% PFOA/PFOS reduction among a broader list of emerging contaminants (pharmaceuticals, herbicides, pesticides). Clearly Filtered's PFAS-specific number is slightly higher, but Aquasana's NSF 401 certification covers more contaminant categories overall.
Why does Aquasana's pitcher need electricity?
Aquasana's Clean Water Machine uses powered filtration to force water through its Claryum filter cartridge at pressure, rather than relying on gravity alone. This produces a much faster flow rate (about 0.5 gallons per minute) than a gravity pitcher, at the cost of needing a nearby outlet and a docking base that takes more counter space than a standard pitcher.
Which filter lasts longer between changes?
Aquasana's filter lasts substantially longer: about 320 gallons or roughly 3-6 months, compared to Clearly Filtered's 100 gallons or roughly 2-4 months. A household using 1-2 gallons a day changes the Aquasana filter about 2-3 times a year versus Clearly Filtered's 3-5 times a year.
Is Aquasana's powered pitcher worth the higher upfront cost?
For households prioritizing speed and lower long-term filter costs, yes. The Clean Water Machine costs roughly $130-200 upfront versus Clearly Filtered's $90-100, but Aquasana's longer filter life and lower per-gallon filter cost narrow the gap within 12-18 months and pull ahead over 5 years.
Does Aquasana's powered pitcher remove lead?
Yes. Aquasana's Clean Water Machine is NSF/ANSI 53 certified for lead reduction at 99%, matching the strength of Clearly Filtered's independently lab-tested 99.34% lead reduction. Both filters treat lead as a core target contaminant, not an afterthought.
Can either filter be used without power in a blackout or off-grid?
Clearly Filtered works anywhere with no electricity required, making it the better choice for off-grid use, camping, or power outages. Aquasana's Clean Water Machine requires a 100-240V outlet to run its powered filtration cycle and will not function without power, which is a meaningful limitation for emergency preparedness.
Bottom Line
Clearly Filtered and Aquasana's Clean Water Machine both hold accredited third-party certification for PFAS, lead, and chlorine reduction, so this comparison comes down to how you want your water filtered rather than whether the filtration works. Clearly Filtered wins on portability, off-grid reliability, and lower upfront cost. Aquasana wins on speed, filter longevity, and long-term cost per gallon.
If you want a filter that works anywhere without power, at the lowest possible entry price, Clearly Filtered is the better fit. If you have counter space and outlet access and want faster fills with fewer filter changes over time, Aquasana's Clean Water Machine is the stronger long-term value.
Test your water before buying either system. The EPA's Consumer Confidence Report program provides free access to your municipality's annual water quality data, and a home test kit covering PFAS, lead, and chlorine will tell you which contaminant profile you are actually dealing with.
