- Why it matters: Homeowners and renters can trust lab-verified performance while saving money.
A surge in water-filter sales has coincided with growing concerns over contaminants such as chlorine, microplastics, PFAS, and heavy metals. While many brands promise clean water, only a few back those claims with third-party lab tests. Clearly Filtered is one of the few that does, and it is currently offering significant discounts on all its products.
Lab-Certified Performance
Independent laboratories NSF and IAPMO test filters against international standards. Clearly Filtered‘s pitcher and under-sink systems have both received NSF certification for chlorine and PFAS removal. In addition, the company released IAPMO lab results that show near-elimination of hundreds of other contaminants, many of which lack official standards.
The pitcher uses a carbon filter and other media to target:
- Free chlorine
- PFAS and PFOA
- Various heavy metals
Unlike competitors that strip all dissolved solids-such as ZeroWater, which leaves the water tasting flat-Clearly Filtered retains natural minerals, preserving a pleasant taste while cutting chloramine and other chemicals.
Pricing and Discounts
Currently, Clearly Filtered offers:
- A blanket 10% discount on every filter purchased through its website.
- An additional 19% off when a customer provides a phone number to receive a promo code.
These savings apply to all product lines, including the 32-ounce stainless-steel bottle and the three-stage under-sink system. The discount structure makes it easier for both renters and homeowners to access high-quality filtration without a steep upfront cost.
How the Filters Work
Pitcher
- Uses activated carbon to remove contaminants.
- Filtering a half-gallon takes about 13 minutes.
- Priming involves squeezing water through a fragile plastic bag; the bag can be reused or replaced for $15.
- The filter slightly increases total dissolved solids, but trace amounts of activated carbon are generally harmless.
32-Ounce Bottle
- Similar filtration technology as the pitcher.
- Requires users to suck water through a filter attached to a spout.
- Suitable for outdoor use; comparable to backpacking filter straws but more socially acceptable.
Three-Stage Under-Sink System
- Installs in-line with the existing water line, no drilling required.
- Installation takes less than five minutes; no landlord approval needed.
- Priming takes at least fifteen minutes of running water; full performance may require a half-hour of use.
- Lab reports show PFAS removal at or near 99%.
- Slight reduction in flow rate, but not enough to be bothersome.
Installation Guide
- Turn off the cold water line.
- Unscrew the valve connection.
- Attach the Clearly Filtered system to the water line.
- Prime the filter by running water for at least fifteen minutes.
- Test the water; PFAS and chloramine should be undetectable.
The system works with any standard tap and does not require a separate faucet or additional plumbing.
Competitor Comparison
| Feature | Clearly Filtered | ZeroWater |
|---|---|---|
| Mineral Retention | ✔️ | ❌ |
| Taste | Pleasant | Flat |
| Lab Certification | NSF & IAPMO | None |
| Installation | 5-min in-line | Requires separate tap |
ZeroWater’s approach removes nearly all dissolved solids, which can negatively affect taste. Clearly Filtered strikes a balance between contaminant removal and preserving natural mineral content.
Key Takeaways
