    • I LOVE THESE!
Scent: Clean Burst
I have them on reorder because of how well they perform. I keep one in my laundry room one in my son’s closet and one in the linen closet. It collects water and balances out the humidity levels and removes the smells. It’s a 10/10.

    • Arm & Hammer Moisture Absorber: A Miracle Worker for Our Church Building
Scent: Fragrance Free
When it comes to maintaining a clean and welcoming environment in our church building, the Arm & Hammer Fragrance-Free Moisture Absorber and Odor Eliminator has proven to be an invaluable tool. Faced with the challenge of eliminating persistent rodent smells and mustiness, this product delivered beyond our expectations. Effective Odor Elimination One of the most impressive features of this product is its ability to neutralize even the most stubborn odors. Our church building had been plagued by rodent smells and a lingering mustiness that regular cleaning couldn't fully eradicate. Within days of placing the Arm & Hammer Moisture Absorbers around the affected areas, we noticed a significant improvement. The air felt fresher, and the unpleasant odors were effectively neutralized. Fragrance-Free Solution The fragrance-free formulation is a huge plus. Many odor eliminators rely on strong scents to mask smells, which can be overwhelming and counterproductive in a communal space like a church. Arm & Hammer's product eliminates odors without adding any artificial fragrance, making it ideal for sensitive environments where people gather to worship and socialize. Moisture Control Excess moisture can be a breeding ground for mold and mildew, contributing to musty smells and potential health hazards. This moisture absorber not only tackles odors but also effectively reduces humidity levels, preventing the growth of mold and mildew. Our church hall, which often felt damp, is now noticeably drier and more pleasant. User-Friendly and Discreet The 14 oz. tubs are compact and easy to place around the building. We strategically positioned them in corners, behind furniture, and near problem areas. They work silently and discreetly, ensuring that our church remains welcoming and comfortable without drawing attention to the odor control efforts. Long-Lasting Performance Each tub lasts for several weeks, providing continuous odor elimination and moisture control. This longevity means fewer replacements and less maintenance, allowing us to focus on other important tasks. The 3-count pack offers great value, ensuring we are well-stocked to maintain a fresh environment throughout the building. Affordable and Reliable Arm & Hammer has long been a trusted name in household products, and this moisture absorber and odor eliminator lives up to the brand's reputation. It’s an affordable solution that delivers reliable results, making it an essential part of our building maintenance routine. Conclusion The Arm & Hammer Fragrance-Free Moisture Absorber and Odor Eliminator has transformed our church building, effectively eliminating rodent smells and mustiness while controlling moisture levels. Its fragrance-free, user-friendly, and long-lasting design makes it a standout product that we wholeheartedly recommend. For anyone facing similar challenges in maintaining a fresh and welcoming environment, this product is a game-changer. ... show more

    • It Works!!

Review Image by iamdebster iamdebster
I'm very impressed with this product. One of my bathrooms had a very musty odor due to poor ventilation. I could temporarily mask it with air freshener, but it would always return. I was also concerned that the constant moisture would attract mold. I decided to give this product a try and was pleasantly surprised. I placed the tub on top of a wall mounted shelf (I moved it forward for the photo) at the end of November. The photos were taken today, January 16th. It took a while to see liquid accumulated in the tub, but the musty odor was gone within a week or so. I highly recommend this product because it works! ... show more

    • Great value!
Scent: Fragrance Free
Arms & Hammer moisture packs work really well at keeping things fresh and dry. The pack of 3 is a great value, easy to use, and lasts a long time. Perfect for closets, bathrooms, or any small spaces that need moisture control!

    • Works but no odor elimination
Scent: Clean Burst
They did trap moisture and fill up over time which was good and proved it worked but I didn't notice any scent or smell changes to the room. When you first open it, there is a little scent, but when it sits out, there wasn't any change or scent added to the surrounding area. Given this is why I bought this brand, it was a little disappointing. So far the lesser name brand does better at both odor eliminating and moisture collection. ... show more

    • Amazing!!! Love!!
Scent: Clean Burst
Amazing!! Good smell but not overly powerful and overwhelming. Took the musty stench right out of our closet within a matter of a day or two. My grandma's Tupperware cabinet had a super strong smell of food and within a few days this took care of it completely when that smell was so strong so I was very impressed. I like that you can refill it and you don't need to buy a big new tub every time. So happy! Thank you arm and Hammer. Side note, their dog toothpaste is a miracle worker too! The yucky smell is gone immediately after brushing for a couple minutes. ... show more

    • Very effective, make sure you replace as suggested
Scent: Fragrance Free
As a homeowner i can't believe I hadn't gotten these sooner. I originally got them to help absorb moisture after using the humidifier in my daughter's room. These are so effective and worth the buy. I use them under my kitchen sink and in bathrooms as well now. Really keeps the air fresh in areas susceptible to moisture. You can see the water in the bottom after a while. I buy the unscented to keep it neutral. ... show more
