Most of our ingredient pages are about molecules. This one is about fleece. Alpaca wool is the fiber shorn from alpacas, domesticated animals from the Andes of South America, and we felt it into dryer balls that tumble with your laundry: a reusable swap for single-use dryer sheets. It does its job mechanically, not chemically.
Bottom line: Our dryer balls are 100 percent alpaca wool with no added scent. They work by keeping clothes apart in the dryer, and you reuse the same set instead of buying a sheet for every load.
Quick facts
- What it is: Alpaca fiber (Vicugna pacos), felted into firm balls
- Its job in our products: Tumbles between clothes and separates them so warm air can circulate
- Material: 100 percent alpaca wool
- Scent: Fragrance-free, with no added scent
- Set size: Pack of 3
- Use: Reusable, load after load
Alpaca vs sheep wool
Alpacas are camelids, close relatives of llamas. Yes, we noticed. Their fleece differs from sheep's fleece in a way that matters to some people:
- Lanolin: Sheep's fleece carries lanolin, a natural wax often called wool wax, and some people are sensitized to it (Lis, 2024).
- Grease: Raw alpaca fleece carries very little grease. Researchers measuring alpaca fiber noted "the lack of grease in alpaca wool samples" (Gishen & Cozzolino, 2007).
- What that does not mean: Low grease does not make alpaca wool allergy-proof, and we make no allergy claims for it. If you react to wool or other animal fibers, keep that in mind before you buy.
How dryer balls work
There is no cleaning chemistry here. In the dryer, the felted balls tumble between your clothes and keep them from clumping together, which lets warm air move through the load more freely.
We do not promise a set number of loads, a specific cut in drying time, or an end to static cling in every load, because results depend on your dryer, the size of the load and the fabrics in it. Our guide on how to use wool dryer balls covers getting the most from them.
The chemistry happens earlier, in the wash. The Complete Fragrance-Free Laundry System pairs the dryer balls with a detergent that contains saponified coconut oil and the enzyme amylase.
From fleece to dryer ball
Alpacas were domesticated in the Andes and are raised for their fleece. The fleece is shorn and cleaned. To make a dryer ball, the fiber is felted: worked with moisture, heat and friction until the fibers lock together into a dense ball. Our dryer balls are 100 percent alpaca wool, as stated on the product page.
How it fits our ingredient standards
The usual ingredient checks are built for chemicals, not fibers. EPA's Safer Chemical Ingredients List does not cover wool, EWG's Guide to Healthy Cleaning has no entry for alpaca wool, and a natural fiber has no CAS number. What we can say plainly: one material, no added fragrance, and a single-use product replaced by one you keep using. The rest of our checklist is on how we vet ingredients.
Handling and safety
- Use the dryer balls as directed on the packaging.
- Dogs often treat them as toys, so store the balls out of reach of pets and small children between loads.
- If a ball starts to come apart, retire it.
