Our take
Kirkland Signature model 1304047 is a straightforward 10-cup pitcher with two included cartridges and an electronic replacement reminder, according to Costco's product documentation. Its listed filter claims cover chlorine and chloramine taste and odor and several named substances, with WQA certification to NSF/ANSI 42, 53, and 401. That is useful documentation for a shopper who wants those specific claims. Costco does not list lead or PFAS reduction for this model, and its current product page does not authenticate the old Amazon parent in row 45. Treat the old listing as a separate unresolved marketplace record and confirm the model label before purchase.
Consider the Kirkland 1304047 if you want a documented 10-cup pitcher, two included filters, named NSF/WQA claims, and an electronic reminder. Check the exact model number and package before buying through a historical marketplace listing..
Do not choose this pitcher to satisfy a lead- or PFAS-reduction requirement based on Costco's listed claims; neither is documented on the product page. It is also not a match if you need verified dishwasher instructions, a TDS meter, or proof that a particular old Amazon parent is this model.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Costco documents a 10-cup capacity, model 1304047, and a package with two filter cartridges.
- The listed claims include chlorine and chloramine taste and odor, mercury, copper, cadmium, benzene, zinc, and several other named substances, with WQA certification to NSF/ANSI 42, 53, and 401.
- An electronic cartridge reminder is included, and Costco gives an approximate two-month or 150-liter interval for each filter.
What to weigh up
- Costco's published claim list does not include lead, PFOA/PFOS, or microplastics reduction; do not infer those claims from the standards alone.
- The page says each filter lasts up to two months or 150 liters but does not provide a model-specific daily processing limit or the full depth dimension.
- The historical Amazon parent is not mapped to Costco model 1304047, and dishwasher care instructions are not established by the source used here.

Full review: how the features affect your choice
What the features mean for you
A clear size and model, with one listing gap
Costco identifies the pitcher as Kirkland Signature model 1304047 and specifies a 10-cup capacity. It lists a height of 10.04 inches and width of 5.91 inches, but does not give the depth on the product page. The row 45 historical title also says 10 cups and two cartridges, which is consistent with Costco's current model description. That agreement supports reviewing the 1304047 family, but does not prove the old Amazon parent or exact historic bundle. If you are comparing shelf or refrigerator fit, measure your available space and check all three dimensions on the package rather than treating the partial dimensions as a complete fit check.
Use only the reductions Costco actually names
Costco lists reductions for chloramine and chlorine taste and odor, mercury, copper, cadmium, benzene, zinc, 1,2,4-trichlorobenzene, estrone, meprobamate, trimethoprim, and limescale. It also says the model is tested and certified by WQA against NSF/ANSI Standards 42, 53, and 401. These labels do not establish that every possible contaminant is reduced: the product page does not list lead, PFOA/PFOS, or microplastics claims. Match a must-have contaminant to a named claim and the certification record, and contact the manufacturer if your requirement is not listed. The profile does not treat the presence of a standard number as a universal purification promise.
Two filters set up the first replacement cycle
The documented package includes two cartridges. Costco says each can last up to two months or 150 liters, which is approximately 39.6 US gallons when converted from the stated metric volume. Actual use and source-water conditions can affect how long a filter remains appropriate to use, so treat the two-month figure as an upper schedule from the product page rather than a guaranteed result for every household. Costco's page does not specify a maximum daily flow or a separate certified service capacity in gallons. If your water use is high, confirm the current replacement guidance before relying on the calendar interval alone.
An electronic reminder helps with routine, not water testing
Costco identifies an electronic cartridge reminder as part of model 1304047. That gives the owner a prompt associated with cartridge replacement, but the page does not say that the reminder measures contaminants or tests water quality. The data also does not specify whether the reminder can be reset for a particular filter age or usage pattern. Households that want a simple visual cue may find the electronic reminder useful; anyone who needs a water-quality result should use an appropriate test and local water information instead of treating a replacement display as a measurement.
Check care details and exact product identity before ordering
The official product page provides core comparison facts but not every everyday-use answer: it does not state whether the pitcher is dishwasher safe, which replacement cartridge code it uses, or the maximum water temperature. Those are unknown here rather than assumed from another brand's filter fit or from online compatibility claims. Costco's model details are useful for identifying the current 1304047 product, but the old Amazon ASIN in row 45 remains unverified. Use the tagged search for the exact model and confirm 1304047, the included cartridges, and the seller's return terms before relying on a marketplace listing.
