While it might seem like an efficient way to save space, vacuum storing down requires caution. You can use vacuum storage bags for down items like comforters or jackets, but you should avoid fully compressing them.
The Impact of Compression on Down
Down is composed of delicate clusters of feathers that trap air, providing insulation. The key issue with vacuum storage, as highlighted by our reference, is the potential for damage:
The same issue applies to storing your down comforter in a vacuum bag. By compressing your comforter down, they can damage the feathers.
Full compression squashes these delicate clusters, potentially breaking the quills or crushing the fluffy barbs that give down its loft (its ability to expand and trap air). Over time, this can permanently reduce the item's insulating power and comfort.
How to Safely Store Down in Vacuum Bags
Fortunately, there's a workaround mentioned in the reference:
You can get away with using a vacuum bag so long as you leave around a bit of air in the bag so you don't fully compress the feathers.
This means you can utilize vacuum bags for space-saving, but you should only remove most of the air, not all of it.
Here’s how to do it safely:
- Insert the Item: Place your clean, dry down item into the vacuum storage bag.
- Seal Most of the Way: Seal the bag almost completely, leaving a small gap.
- Remove Some Air: Use your vacuum cleaner to draw out air, but stop when the item is compressed by only about 50-70%. You should still feel significant resistance and the item should retain some of its bulk.
- Seal Immediately: Quickly seal the bag the rest of the way.
- Check Periodically: Ensure the bag hasn't lost its seal and that the item isn't being accidentally crushed if other items are placed on top.
Alternatives to Vacuum Storage
For optimal long-term storage and to fully preserve the loft of your down items, consider these alternatives:
- Breathable Storage Bags: Many down products come with large, breathable fabric bags. These protect the item from dust and pests while allowing the down to remain fluffy.
- Large Cotton or Mesh Bags: Similar to manufacturer bags, these allow air circulation and prevent compression.
- Store Uncompressed: Ideally, store down items loosely folded in a cool, dry place, like on a shelf or in a large bin, without significant weight on top.
Using a vacuum bag while leaving some air in provides a middle ground, offering more space-saving than traditional bags while minimizing the risk of feather damage.
