Clearly Filtered review: the water pitcher, its listings and the lab claims

Clearly Filtered sells on a long list of substances, and only chlorine from that list is in a listing. These models have a listing for the substances people most often buy a Clearly Filtered for. Prices are the brands' own, checked October 13, 2026.

The ZeroWater trade-off is filter life. Its listing rates the filter at 15 gallons, against 100 for the Clearly Filtered, and the brand's own chart ties real life to the minerals in your tap water. The Brita costs the least to run. Every pitcher here is compared by listing in the best water filter pitchers. For fluoride, start with reverse osmosis systems.

Clearly Filtered sells four product lines in its US store: a pitcher, an under-sink system, an inline fridge filter and filtered bottles. I took every price from clearlyfiltered.com on October 13, 2026.

Divide the price of each filter on October 13, 2026 by its rated gallons and the bottle comes out most expensive: about $1.52 a gallon. The pitcher filter works out to $0.65, the fridge filter to $0.46, and the under-sink set to about $0.23 over the 2,000 gallons in its WQA listing.

A subscription takes 10% off every filter, so on October 13, 2026 the pitcher filter drops to $58.50 and the under-sink set to $409.50. For other filter types, see all water filters by type and the best under sink water filters.

Yes, for one product and one claim. NSF lists the Filtered Water Pitcher (model P-V3) and its replacement filter (P-RF) under NSF/ANSI 42 for chlorine, taste and odor. The pitcher's performance data sheet gives a 98.2% average chlorine reduction over the rated 100 gallons. The same sheet cites NSF/ANSI/CAN 372, which covers lead in the materials that touch the water, not lead in your water.

WQA lists two Clearly Filtered products, both under NSF/ANSI 42 for chlorine, taste and odor: the pitcher filter at 100 gallons and the under-sink filter at 2,000 gallons. I found no listing for the bottles or the fridge filter at NSF, WQA or IAPMO as of October 13, 2026.

IAPMO comes up in a second way. Clearly Filtered's lab tables were produced by QFT, “a lab now operating as IAPMO New Jersey.” That is contract lab work, not an IAPMO certification, and the IAPMO directory showed no listing under the brand.

The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.

Each product has a performance page with a long table of substances and a percentage beside each. These are Clearly Filtered's own claims. The note under the pitcher table says the results “are the maximum removal percentage” and that “not all contaminants that were tested had established NSF/ANSI protocols at the time testing was performed.”

Two details matter more than the percentages. First, chlorine: the brand's table gives more than 99.52% for the pitcher, while the NSF data sheet gives 98.2% averaged over the filter's life. A maximum and an average are different numbers, and only the average went through certification.

Second, the dates. The under-sink and fridge filter pages show the same test date, April 17, 2018, and the same results. The bottle page is dated December 4, 2017. Only the pitcher was retested, in November 2025.

On Amazon the pitcher averages 4.1/5 from 1,092 ratings (checked October 13, 2026). Amazon groups review mentions by topic. Taste gets the most approval: 133 of 142 mentions are positive. Leakage draws the most complaints: 67 of 77 mentions are negative. Value for money (75 of 116 negative) and filtering speed (34 of 49 negative) also lean negative.

On r/WaterTreatment, the doubts are about the claims, not the taste. In a “Debunking ClearlyFiltered?” thread with 48 upvotes and 101 comments, the poster calls the brand's explanation of how its filter works “very sales-pitchy” and would “be less concerned if they actually received any NSF certifications.” NSF now lists the pitcher, for chlorine only.

In a thread on pitcher lab tests, the poster writes that “Clearly does not include their actual lab report pdf, just a table summarizing.” On October 13, 2026 the performance pages still showed tables. The PDF linked from the pitcher page is the NSF data sheet for chlorine.

Clearly Filtered calls its warranty “limited lifetime” on its product pages and in the pitcher's data sheet. Its return and warranty policy titles the section “2-Year Limited Lifetime” and says the warranty “does not include filters and expires after 24 months from the date of purchase.” I read that as 2 years on the pitcher or system itself, with filters not covered at all, and that is the term in the card above.

The warranty applies only to purchases from clearlyfiltered.com or the brand's official Amazon store. Returns run 30 days under the brand's satisfaction guarantee.

Shipping is free on autoship orders in the US. The shipping page says one-time orders pay a rate based on the order total, while the pitcher page says shipping is free on all US orders. Check the cart before you pay.

On discount codes, the brand's promotion page lists two offers: 10% off and free shipping on autoship, with “no code necessary,” and 10% off your first filtration system when you sign up with an email. The subscription page has the autoship terms. I don't list coupon-site codes, because I can't confirm they work.
