Smelly-Cute. Dryer-Only. Shockingly Useful.

Small Friends, Big Clean

Odor Otter is named after real otters: notoriously smelly… and impossible not to love. Inside is a regenerable bead blend that captures moisture and odor compounds.

Dryer use: If you forgot laundry and it smells musty, you don’t have to rewash. Toss Odor Otter in the dryer with the load to help remove mildew odor and dry more efficiently.

Dryer use only. Do not put Odor Otter in the washing machine. It will saturate with water and detergent and can’t do its job until fully dried again.

How Odor Otter Works

🔥

1. Dryer Reset

Odor Otter is regenerated by heat. When it stops working, run it through the dryer to reset the beads.

🧺

2. Rescue Musty Laundry

Forgot to move laundry and it smells mildew-y? Put Odor Otter in the dryer with the load to help remove odor without rewashing.

💨

3. Help Your Dryer Work Better

Use it with heavy loads (towels, synthetics) to help pull moisture from the air as clothes dry.

🏠

4. Use Anywhere

Closets, bathrooms, mudrooms, cars—anywhere moisture and stale smells build up. Keep out of reach of pets and small children.

What It’s For

😮‍💨

Musty / Mildew Odor

Designed to capture odor compounds—especially that “forgot the laundry” mildew funk.

💧

Moisture Control

Helps reduce dampness in enclosed spaces like closets, bathrooms, and cars.

🔥

Regenerable

When it stops absorbing odors/moisture, it just needs a dryer cycle to reset.

🧺

Dryer-Only for Laundry

Use it in the dryer—never the washer. Saturated beads can’t capture until fully dried again.

🚗

Cars & Rainy Seasons

Absorbs moisture that contributes to foggy windows and stale interior smells.

🐾

Pet Areas (Out of Reach)

Place near litter boxes or pet bedding for ambient odor—but do not let animals chew or eat it.

  • Inner packet filled with a regenerable bead blend
  • Beads: silica, 3A sieve zeolite, and activated alumina

🧺 Dryer use only (do not wash)

Use It For:

  • “I forgot the laundry” moments
  • Gym clothes, towels, synthetics
  • Closets, bathrooms, mudrooms
  • Cars (especially in wet climates)
  • Near litter boxes (out of reach of pets)

Small by Design. Built to Fund More.

Odor Otter is our start. It’s a small, ordinary object—built carefully, on purpose. It solves one real problem, and revenue from this product helps fund public-benefit research inside the MAAD ecosystem.

Not everything needs to be world-changing on its own. Small, ordinary tools—done thoughtfully—can support much bigger systems. Odor Otter proves we can build something real, learn from it, and build again.

Revenue Funds Research

Every Odor Otter sold helps support public-benefit research—without VC pressure or exit timelines.

Next Up: The Clam

A laundry microplastic capture system designed for mass accessibility and recyclable end-of-life.

Who We Are

Odor Otter is part of a larger experiment in how everyday products can support public-benefit research. We’re built by MAAD — a public-benefit research foundry focused on taking real, applied science out of the lab and into everyday life.

Not everything needs to be grand on its own. Small, ordinary tools—done thoughtfully—can fund much bigger systems. Odor Otter is our first step.
