Your needs, this model
Does it fit your priorities?
Would an eight-cup / 64-ounce glass pitcher meet your serving size?
The exact P-681705 page lists 64 ounces, or eight US cups. It does not publish external dimensions, so listed capacity alone does not establish refrigerator clearance.
Explore this need in the finder →Is the 40-gallon / two-month universal filter limit acceptable?
All Hydros vessels use the Multi-Filter; Hydros recommends replacement every 40 gallons or two months, whichever comes first. This pitcher does not extend that limit.
Explore this need in the finder →Does your need depend on a documented reduction beyond chlorine taste/odor and particles?
The Hydros materials inspected report NSF/ANSI 42 testing for chlorine and Class I particulate reduction. No exact-model lead or microbial result was found, so an essential need for either excludes this pitcher.
Explore this need in the finder →The larger Hydros glass pitcher, using the same cartridge
The Hydros 64 oz Glass Water Filter Pitcher is the family’s larger glass option: the manufacturer lists 64 ounces, or eight US cups. That is two cups more than the 40-ounce slim bodies and useful if you serve a few people from one vessel. The trade is physical fit. Hydros’ FAQ gives its generic Pitcher format as 5.25 inches wide, 10.8 inches high and 1.05 lb unfilled, although it does not cross-reference P-681705 by SKU. The FAQ prints the length as “6.”, which is malformed; do not rely on a guessed length. Measure your space and consider the filled load before buying; a glass pitcher is less forgiving of a drop than a plastic one.
This configuration is not a different filtration system. Hydros says all its vessels use the same Fast Flo Tech Multi-Filter, which snaps into the bottom of the lid or cap. Its FAQ suggests pouring at about one ounce per second; the 64-ounce product page says a full pitcher filters in about a minute. Those are manufacturer descriptions, not a timing test performed here. The filter’s stated 40-gallon/two-month replacement recommendation remains in place even though this body holds more at a time. A 64-ounce pitcher may make a household’s batches more convenient, but it does not increase the cartridge limit.
What Hydros documents about the filter
The company describes its cartridge as coconut-shell carbon in a BPA-free casing. Hydros’ FAQ reports more than 90% chlorine reduction through 40 gallons and Class I particulate reduction under NSF/ANSI 42 testing by Torrent Labs. The FAQ links a pitcher-family data table that shows 93% average and 89% minimum chlorine reduction, with over 99% average and minimum for Class I particles under the listed test values; the table does not identify P-681705 specifically. Treat that as limited, maker-reported family performance rather than a SKU-specific minimum guarantee. The materials reviewed for this exact pitcher do not document a lead, fluoride, PFAS or microbial reduction result. The manufacturer’s NSF-related wording should not be mistaken for proof of certification unless a current certification listing for this exact filter and claim is verified. This is a taste-and-particle option for cold, already safe water, not a purifier for microbiologically unsafe water.
Hydros recommends replacing the filter at two months or 40 gallons, whichever arrives first, and says to keep use at or under five gallons daily for best results. It also advises users to avoid hot water above 90°F, freezing the filter or pitcher, and putting other beverages through the filter. For first use, remove the filter, hand-wash vessel parts, rinse the cartridge with cold water for 15 seconds, snap it into the lid and follow the maker’s fill direction. Initial carbon flecks or slower flow can be normal. Hydros says not to wash the filter. The general FAQ says pitcher bodies are hand-wash only; no product-specific dishwasher allowance appears on this 64-ounce page.
Capacity is the meaningful difference from the 40-ounce model
Hydros also lists a 40-ounce glass slim pitcher. That option is narrower in its name and holds five cups; the P-681705 body holds eight. Both use the same filter and have the same 40-gallon/two-month service limit, so the choice is really how much water you want in the vessel and how the body fits your space. The 40-ounce glass page specifically states that its glass body is dishwasher-safe while its lid is not, but the brand’s general FAQ contradicts this and says pitchers should not go in the dishwasher. That conflict is a reason not to assume the larger pitcher is dishwasher-safe; hand washing is the conservative choice.
A Waterdrop, Brita, PUR or Culligan pitcher may be a better fit if you want a different replacement system, body shape or published performance table. The Hydros advantage here is a simple shared filter and quick refill claim—not a separate lead-reduction route or an integrated reminder. There is no documented filter-life indicator or TDS meter for P-681705 in the pages reviewed. A dated reminder will be necessary if you want to follow the two-month service limit.
How the finder handles this model
Select eight cups, the Hydros Multi-Filter route and a glass body to bring this configuration into the matching plan. Choosing five cups shifts to Hydros’ 40-ounce options instead. A required filter capacity above 40 gallons excludes the whole Hydros family, and a lead or microbial claim is not a positive match because the inspected materials do not document those results. The FAQ’s generic Pitcher height is 10.8 inches, while the 40-ounce Slim Pitcher figure is 10.6 inches. With a strict 10.7-inch height limit, the two slim bodies remain possible and this larger format does not. This pitcher is best for someone who wants the larger glass format and accepts the same narrow filter claims and manual replacement routine as the smaller sibling.

| What the filter is documented to reduce | Hydros reports over 90% chlorine reduction through 40 gallons and Class I particulate reduction. Those are maker-reported test claims against NSF/ANSI 42, not a broad safety claim or local-water result. The FAQ links a pitcher-family performance table showing 93% average / 89% minimum chlorine reduction and over 99% average / minimum Class I particle reduction under the displayed values; that table does not name this exact SKU, so do not treat the averages or FAQ summary as an SKU-specific minimum guarantee. |
| Use and care | Use cold water (not above 90°F), not beverages or microbiologically unsafe water. Hydros materials inspected do not document microbial reduction. Follow the two-month / 40-gallon filter recommendation and five-gallon/day best-results cap. |
| Separate TDS meter included | No |
| Manufacturer dimensions as listed | Hydros FAQ lists its generic Pitcher at 5.25 in W x 10.8 in H and 1.05 lb unfilled; the printed length is malformed as “6.”, so length remains unknown. The 64 oz model is the reviewed Pitcher format, but the FAQ does not cite P-681705 by SKU. |
| Pitcher material | Glass pitcher body; Hydros FAQ describes its glass vessels as borosilicate, while the exact P-681705 page says glass. Lid/filter housing materials are not itemized. |
| Manual-stated daily use limit | 5 gal/day |
| Button-controlled electric dispensing | No |
| Stainless-steel body | No |
