Regular Zeolite for home odor removal
Closets, mudrooms, basements, and everyday household spaces: start with Regular Zeolite when choosing zeolite for odor removal at home.
The coarse mineral rocks are easy to place in an open container, keeping the material together while allowing air to reach it.
- Choose a stable, open container for the rocks.
- Place it near the odor source, with the mineral exposed to the air.
- Check the area and the material regularly, and follow the product directions.
Closets · Mudrooms · Basements
One mineral. Three grades.
Start with the job you have in mind. Particle size helps you choose the right form of zeolite.

Granular
Smaller granules · 1.4–4 mm
Blending into soil, potting mixes, and container planting.
Fine Dust
Finely milled powder
Chicken dust bathing and the fine-grade uses in our flock-care guide.
Chicken care
Two ways to care for your flock
Zeolite earns its keep two ways — as a soft, finely milled dust bath that helps hens keep feathers clean and dry, and as a coop and run treatment that absorbs droppings moisture and locks up ammonia.
- Fill a tub or dust box a few inches deep with Fine Dust and let your flock do the rest.
- Sprinkle Fine Dust or Granular over coop floors, droppings boards, and nesting boxes.
- Refresh as needed and replace when soiled.
Garden & soil
Build your garden from the ground up
Mixed into beds and potting soil, zeolite improves drainage and aeration while acting as a slow-release reservoir for water and nutrients — reducing how often you water and how much fertilizer leaches away.
- Blend Granular into the top 4–6″ of soil at roughly 1–2 lbs per square yard, or about 5–10% of a potting mix.
- For raised beds and new lawns, work it in before planting.
- Top-dress with Regular grade around established plants.
Houseplants
Get to know your potting mix
Succulents and cacti die more often from too much water than too little. Zeolite gives a fast-draining mix that never stays soggy — while its channels hold a small moisture buffer that evens out the wet-dry cycle.
- Blend Granular as one-quarter to one-third of a gritty succulent or cactus mix.
- For pothos, snake plants, orchids, and bonsai, mix a handful into the soil for better aeration.
- Add a thin layer of Regular as a top dressing — it looks clean, helps deter fungus gnats, and won’t grow mold.
The science of zeolite
Zeolite is a family of natural minerals formed when volcanic ash settled into ancient lakes and seas and crystallized over thousands of years. Ours is clinoptilolite — the most useful and well-studied type — mined and milled in the USA at 85–95% purity, with no crystalline silica.
Under a microscope, each grain is a rigid honeycomb of microscopic channels that packs roughly 24.9 m² of surface area into a single gram — the reason it does so much with so little.
Zeolite’s framework carries a natural negative charge, and that charge does two jobs at once.
Traps odor & ions
A very high cation-exchange capacity (CEC ~180–220 meq/100 g) locks onto ammonium — the source of ammonia odor — plus potassium, calcium, and heavy metals.
Holds water & nutrients
The honeycomb channels soak up moisture and loose nutrients — over 55% of its weight in water — then release them slowly over time.
Lasts a long time
A hard, low-clay mineral (Mohs 3.5–4) that resists breaking down, so it keeps working season after season.
