PETKIT N50 Odor Eliminator 2.0 for PuraMax/PuraMax 2 — 3-Pack Cartridge, 30-Day Odor Control

PETKIT N50 Odor Eliminator 2.0 is a ready-to-install filter cartridge designed to reduce litter-box odors in PETKIT PuraMax and PuraMax 2 self-cleaning cat toilets.

This three-piece pack of N50 2.0 cartridges offers an easy way to maintain a fresher-smelling waste bin without manual deodorizing sprays or frequent bowl cleanups. Each cartridge typically lasts about one month, and the updated plastic case makes swapping units tidier and faster. The N50 2.0 is formulated to be non-toxic and non-irritating after testing, and it’s intended specifically for use with PETKIT PuraMax, PuraMax 2 and Purobot Max Pro models — it is not compatible with the Purobot Ultra. Note: installing the N50 2.0 in a PuraMax unit requires removing the silicone cover from the waste bin lid.

How does the N50 2.0 reduce litter-box smells?

The cartridge contains odor-adsorbing materials in a sealed plastic housing that captures and neutralizes ammonia and other unpleasant smells released from the waste bin. It works passively while the litter box operates, making it a low-maintenance complement to the unit’s self-cleaning cycle.

• Adsorptive media traps odor molecules before they escape the waste compartment.
• Sealed plastic case reduces direct contact and makes replacements cleaner.
• Designed to work continuously for roughly 30 days per cartridge.

Will installing N50 2.0 affect my cat or the litter box operation?

The N50 2.0 is non-toxic and non-irritating according to PETKIT testing, and it’s engineered to sit inside the waste bin without changing the automated cleaning function. Proper placement is important — follow the instructions to avoid interference with sensors or moving parts.

• Safe for pets when used as directed; avoid placing inside reach of curious paws.
• Fits into designated cartridge slot in PuraMax, PuraMax 2, and Purobot Max Pro models.
• Does not require wiring or power; the unit operates passively alongside the box.

How do I install and replace the cartridge in my PuraMax series box?

Replacement is straightforward: open the waste compartment, remove the spent cartridge, and insert a fresh N50 2.0. If you have a PuraMax model, remove the silicone cover on the waste bin lid first so the cartridge sits properly in the slot.

• Turn off the unit or pause cleaning cycle before opening the waste bin for safety.
• Remove the silicone lid cover on PuraMax units to access the cartridge bay.
• Slide in the new cartridge until it clicks or sits flush; dispose of the used cartridge hygienically.

What should I expect in terms of lifespan and packaging?

Each PETKIT N50 2.0 cartridge is designed for approximately one month of typical household use, so the three-pack covers about three months for one litter box. The updated plastic case helps keep hands clean during replacement and provides a neat, sanitary housing for the odor-adsorbing media.

• Three cartridges included per pack; one cartridge ≈ 30 days.
• Plastic casings improve handling and reduce contact with spent media.
• Sold as replacement refills — keep original box instructions for compatibility details.

Who is this for: PETKIT N50 Odor Eliminator 2.0 is a practical accessory for pet owners using PETKIT PuraMax, PuraMax 2 or Purobot Max Pro self-cleaning litter boxes who want a hands-off approach to controlling odors. It’s ideal for busy households, small apartments where odor control matters, or multi-cat homes seeking fresher indoor air without extra sprays or cleaners. If you own a Purobot Ultra, choose a compatible alternative; otherwise, this three-pack offers a tidy, monthly-refresh solution to keep your self-cleaning litter box smelling better between full cleanouts.
