Comparing Moisture Absorber Effectiveness
Silica Gel vs. Calcium Chloride
Absorption Rate
You want to know which moisture absorber works fastest. Silica gel absorbs about 40% of its weight in water. Calcium chloride pulls in up to 300% of its weight. You see the difference right away. Silica gel works best in low or moderate humidity. Calcium chloride handles high humidity and turns into liquid brine when it gets full. Here’s a quick look:
乾燥剤 | Moisture Absorption Rate | Suitability |
|---|---|---|
シリカゲル | Absorbs about 40% of its weight | Effective in low to moderate humidity levels |
Calcium Chloride | Absorbs up to 300% of its weight | Best for high-humidity environments, but turns to liquid brine when saturated |
If you need to keep storage boxes dry, silica gel packets do a great job. For basements or bathrooms with lots of moisture, calcium chloride is the stronger choice.
Cost Comparison
You probably want to save money while keeping things dry. Calcium chloride pellets cost much less than other options. For example, a 50-pound container of DIY bulk calcium chloride costs about $22. DampRid tubs cost much more for the same amount. Silica gel is affordable for small projects, but calcium chloride gives you more value for big jobs. Here’s a price comparison:
