Arm & Hammer Odor Absorbers for Closets, Pets and Damp Rooms

The Arm & Hammer Clean Burst Moisture Absorber and Odor Eliminator Tubs come as a 3-pack of 14-ounce tubs. A moisture absorber is a small container of crystals that pull water out of humid air. As they work, the crystals dissolve and water collects in the tub. Less dampness means less of the musty smell that comes with it, which is why these are described as both moisture absorbers and odor eliminators.

The description says you pour a packet into the canister and close the lid, then discard once used up, so this set appears to work with packets rather than prefilled tubs. It suggests using the tubs one at a time for long-lasting freshness or spreading them between the bathroom, laundry room, kitchen or home office, and even as a shoe deodorizer. The Clean Burst name indicates a scent. The listed weight of 1.27 pounds seems low for three 14-ounce tubs, so the listing may be describing the packaging rather than the fill. WM Barr is named as manufacturer.

This suits households with a few damp spots who like a light fresh scent. If anyone in the home is sensitive to fragrance, the refillable or Essentials tubs are fragrance free.

The Arm & Hammer Fragrance Free Refillable Moisture Absorber is a single 14-ounce tub. Setup is simple: remove the lid, peel off the foil cover, replace the lid and place it where excess moisture or stale odor is a problem. When the moisture-absorbing crystals have fully dissolved, you pour out the collected water and refill the tub.

It works the same way as the Clean Burst tubs, pulling moisture from the air to help hold a comfortable humidity level, and can double as a shoe deodorizer or room freshener where dampness is the issue. Being fragrance free, it does not add perfume to a closet full of clothes. The listing does not state how long a fill lasts or whether refills are included. WM Barr is listed as manufacturer.

This is a good fit for a renter with one musty closet or under-sink cabinet who wants a reusable container. If you need several spots covered at once, a 3-pack is more practical.

The Arm & Hammer Essentials Disposable Moisture Absorber and Odor Eliminator tubs come in a pack of three and are fragrance free. The listing says they are powered by three simple ingredients: Arm & Hammer Baking Soda, activated bamboo charcoal and mineral salts, aimed at people who want a more natural solution. Activated charcoal is a very porous material that traps odor molecules, and it pairs well with baking soda for musty smells.

Arm & Hammer claims 10% more moisture absorbing power and a life of up to 60 days, depending on temperature and humidity. The tubs are disposable, so you throw them away once the liquid reaches the fill line. The title lists 1 lb, and the listing calls it an ideal closet dehumidifier, suggesting laundry rooms, mud rooms and closets. WM Barr is listed as manufacturer.

This is the easiest set-and-forget choice for closets and mud rooms. If you would rather refill than replace, the refillable tub is the alternative.

The ARM & HAMMER Fresh Effects Odor Neutralizing Baking Soda Pouches come in a pack of five, each individually packaged. They use natural Arm & Hammer Baking Soda to absorb and neutralize smells rather than cover them up with perfume.

The listing suggests small, enclosed spaces such as the kitchen after cooking, athletic gear bags and car trunks. The formula is fragrance free, and the pouches are a mess-free alternative to sprays or gels. The listing does not say how long each pouch lasts or whether they help with moisture. Church & Dwight is named as manufacturer.

These suit anyone who wants a quick fix for a smelly gym bag or car. For drawers and hampers around the house, the OdorBusterz balls are smaller and come in a larger count. You can also make your own fridge deodorizer with an open box of Arm & Hammer baking soda, 1 lb.

The Arm & Hammer OdorBusterz Odor Eliminator Balls come ten to a pack in the Clean Burst scent. Each ball has a natural baking soda core inside a ventilated shell that lets air circulate around it, so it keeps working in tight spaces.

The listing names closets, drawers, hampers, bathroom cabinets, gym bags, lockers and storage bins. They are simple and mess-free. The listing does not say how long they last. Ginsey Industries is named as manufacturer.

These suit a family with lots of small trouble spots, like a teen’s shoe rack and a laundry hamper. If the smell is really from damp, a moisture tub tackles the cause. For stubborn smells in clothes, pairing these with a good Arm and Hammer laundry detergent helps.

The Arm & Hammer Pet Scents Solid Gel Odor Eliminator is a 15-ounce container in the Fresh Breeze scent. It uses a solid baking soda gel to absorb and neutralize pet odors. It needs no plugs, batteries or sprays; you simply open it and place it in the room. As the gel evaporates, it gradually releases fragrance.

The listing suggests litter box rooms, pet sleeping areas, kennels, mudrooms and closets, and says it is appropriate for homes with dogs and cats. Pets + People Consumer Products is listed as manufacturer.

This suits pet owners who want passive odor control in a whole room. Because it adds fragrance, choose a fragrance-free option for pet-sensitive noses if needed.
