Our take
Naples Naturals' model 109 is one of the better-documented leads in this saved group for setup and maintenance: the maker's manual identifies a 1089 Alkaline Filter Cartridge, instructs users to flush it three times before use, and describes a 60-day countdown timer based on an average cartridge life. The manual does not provide a pitcher capacity, gallon rating, contaminant-specific performance data, or NSF/ANSI certification. It also does not map the old green LCY-G1 Amazon parent to this 109 configuration. Treat this as a current-family review, not a verified match to that historic listing.
Consider the documented 109 family if a digital calendar reminder and explicit first-use instructions are useful, but do not rely on it for a contaminant or certification requirement without additional model-specific evidence..
Do not choose the model 109 to satisfy a hard requirement for documented lead, PFAS, microplastics, chlorine, or mercury reduction, or for an NSF/ANSI certification, based on the reviewed manual. It is also a poor fit if you need a confirmed capacity, gallon-based replacement interval, or proven match to the historic green LCY-G1 parent. The word alkaline in the cartridge name does not establish a water-treatment claim beyond what the maker documents.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manual identifies the exact 1089 Alkaline Filter Cartridge used with the model 109 pitcher.
- A 60-day digital countdown timer includes four bars showing remaining time, making the calendar routine visible.
- The maker explains assembly and requires three initial flush cycles, giving owners specific setup instructions.
What to weigh up
- The manual and current family page do not give a pitcher capacity or a filter throughput in gallons.
- No contaminant-specific reduction data or NSF/ANSI certification appears in the reviewed product sources.
- The green LCY-G1 historic Amazon parent, its package, and its relationship to model 109 remain unresolved.

Full review: how the features affect your choice
What the features mean for you
Use the model number and cartridge code as the identity anchor
The maker-provided manual names a Naples Naturals 109 Alkaline Water Pitcher and lists a 1089 cartridge in the box. Naples Naturals' current home page identifies a 109 pitcher product line. These records support a current model-family profile, but they do not map the historical green listing's LCY-G1 hint or Amazon parent to model 109. The review therefore describes the named 109/1089 family and keeps the old color and listing identity open. Before buying a used or older listing, compare the model label and the cartridge code with the manual.
Treat the digital display as a calendar countdown
The manual says to start the digital timer and wait for 60 to appear; it then counts down over 60 days. Four bars represent 100, 75, 50, and 25 percent of the remaining period, with a bar disappearing every 15 days. The maker calls 60 days the average life of a cartridge, so this is a useful replacement reminder rather than a measurement of filtered gallons or water quality. The manual does not state that the timer detects contaminants, filter blockage, or local water conditions.
Follow the initial cartridge setup carefully
The 1089 cartridge ships inside the upper reservoir, according to the manual. It instructs the owner to screw the cartridge into the bottom of that reservoir, place it in the pitcher body, and snap on the lid. Before drinking, the upper reservoir is filled and allowed to drain three times, with each batch discarded. This is a more involved first setup than simply dropping in a preconditioned cartridge, but the steps are clear. The manual also recommends gently squeezing and shaking the cartridge if flow becomes slow.
Do not infer performance from an alkaline name
The manual describes the 1089 as an Alkaline Filter Cartridge and says taste can vary with the minerals already present in the source water. It does not report a named lead, PFAS, microplastics, chlorine, or mercury reduction percentage, and it does not identify NSF/ANSI testing or certification. That leaves the finder attributes unknown for these claims. A change in taste or an alkalinity reading is not proof that a particular contaminant has been reduced. If a health-related claim is important, ask for a current performance sheet that names the model and cartridge.
Shortlist it only when the unknowns fit your decision
The 109/1089 family may suit a shopper who wants a countertop pitcher with a visible calendar prompt and does not need a known gallon interval. It is not a fit for a hard capacity minimum because the maker sources reviewed here do not list volume. The historical green LCY-G1 listing is also not matched, so do not assume its package or finish is the same. Search for model 109, inspect the included filter code, follow the three flushes, and compare another documented system if you need a specific contaminant claim or a verified certification.

No lead-reduction claim or NSF/ANSI certification is documented in the reviewed model 109 manual. Keep those attributes unknown unless the maker supplies model-specific performance evidence.
