Our Verdict
This product is not a humidifier. It is a 50-pack of cotton filter refill sticks for mini USB humidifiers and car diffusers.
You cannot use these sticks to humidify a room by themselves. You need a compatible portable humidifier first.
The 50-piece count gives you many months of replacements. You can cut each stick to match your device.
At $6.39 for 50 sticks, the per-unit cost is about 13 cents each. That makes regular filter changes affordable.
These work best if you already own a small USB or car humidifier. They keep your device running with fresh, clean wicks.
If you need an actual humidifier for your bedroom or nursery, this product will not help. Look for a standalone humidifier instead.
