Our take
The EHM-WP5 is a documented current pitcher family with a stated 3.5 L vessel and a maker-listed 400 L filter target. EHM also identifies several body and cartridge-shell materials. The product page states a pH range and lists filter media, but those details are not an independently verified contaminant reduction result. Neither historical 3.8 L Amazon parent, including the red three-filter title, is mapped to WP5. Use this review for the current model family and keep exact seller variants open.
Consider the WP5 family if its documented 3.5 L total capacity and stated 400 L cartridge target suit your routine, and if you are willing to confirm the cartridge and care directions for the seller's package. Treat EHM's pH and media descriptions as product-page statements; they do not establish a named reduction claim, an NSF/ANSI certification for the complete system, or a health outcome..
This is not a suitable match if you need a verified lead, PFOA/PFOS, microplastics, mercury or chlorine reduction claim, or a complete-system NSF/ANSI certification. The reviewed product page does not establish those facts. It is also not a fit if you need a confirmed filtered-batch volume, a clear calendar replacement interval, dishwasher-safe care, or authentication of either historical 3.8 L Amazon listing. Do not treat an alkaline label or a maker-stated pH range as evidence that unsafe water has been treated.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- EHM identifies a current model code, EHM-WP5, and a stated 3.5 L total capacity, so this article can discuss a named family rather than a title-only brand guess.
- The maker lists a 400 L filter-life target and qualifies it by water quality, giving a useful volume reference while making its limit clear.
- The product page names the vessel, lid/handle and cartridge-shell materials, which is more useful for checking material preferences than an unsupported generic BPA-free title claim.
What to weigh up
- The reviewed EHM page does not supply contaminant-specific performance results or establish full pitcher-system certification; reduction requirements should remain unknown.
- It gives total capacity but not the filtered-water compartment volume or a fixed calendar replacement interval, so the day-to-day routine is incomplete.
- The 3.8 L historical listing, red finish, three-filter package, model hint and ASIN are not mapped to current WP5 documentation.

Full review: how the features affect your choice
What the features mean for you
Treat 3.5 L as total vessel capacity
EHM's current product page identifies model EHM-WP5 and lists a 3.5 L capacity. That converts to about 14.8 US cups of total vessel volume, but the page does not separately report how much water sits in the lower filtered section after a full cycle. Do not use the total as a promise of an equally large ready-to-pour batch. The historic Amazon titles say 3.8 L, and their exact model and package are not linked to WP5. If finished-water volume is a hard requirement, get a measurement or specification for the exact current seller configuration.
Use the 400 L figure as a maker target, not a measured result
The WP5 page lists filter life of 400 L and says the duration depends on water quality. That is a manufacturer target, not a field-test result and not a fixed number of months. Household volume, source-water conditions and use can change how soon a cartridge needs replacement. The page does not identify a separate calendar interval or a built-in status light. If your routine depends on a two-month replacement schedule or a visual reminder, those details are not confirmed here and should not be supplied from a different EHM model.
A pH statement is not a contaminant-reduction claim
EHM lists a pH range of 8.5 to 9.5 and describes multiple filter media. Those are product-page statements about the water and cartridge. They do not say how much lead, PFOA/PFOS, chlorine, microplastics or mercury is reduced under a named test condition. The page also does not provide a claim-specific NSF/ANSI performance sheet for the whole pitcher. Keep the finder facts for those reductions and certifications unknown. If you have a contaminant concern, use local water information and a treatment product whose documentation names the specific claim you need.
Check materials and care before choosing
The EHM page lists the pitcher body and funnel as food-grade AS, the lid and handle as food-grade ABS, and the cartridge shell as PP. This gives a shopper concrete materials to compare with household preferences. The page does not provide a dishwasher-safe statement for the full vessel, nor does the product size line clearly assign dimensions to a refrigerator-facing orientation. Do not infer dishwasher suitability from the resin names. Confirm care instructions for the exact package, and keep filters away from cleaning steps that the maker does not document.
Keep WP5 separate from the old 3.8 L listings
The current page names EHM-WP5 at 3.5 L. The historical candidate rows contain separate 3.8 L titles, different ASINs, a numeric model hint, a red finish and, for one, a three-filter package. No reviewed manufacturer source maps those details to WP5. This article therefore has its own model-family identity and uses an exact-model Amazon search link rather than a direct product page. Check the seller's model label, filter code, included quantity and replacement instructions before treating it as the same configuration. A current family page can support a useful comparison without resolving every old package detail; that separation is deliberate so a buyer does not assume the two sizes refer to the same vessel. For a buyer comparing pitcher footprints, the two capacity values should remain distinct until a model label or manufacturer source connects the historical package to the current WP5.

Before you buy
Does the WP5 page prove lead or fluoride reduction?
No. The reviewed page lists materials, a pH range and a 400 L filter target, but no claim-specific reduction result for lead or fluoride.
Is the 3.5 L figure filtered-water capacity?
EHM states 3.5 L total capacity. The page does not give a separate filtered-compartment volume.
Is this the same as the historic red 3.8 L three-filter listing?
That mapping is not verified. This article covers the current EHM-WP5 family; the old parent, finish and package remain unresolved.
