Anti Odor/Moisture regulator Filter

Items included:
One pair of reusable anti-odour and moisture-regulating filter
Blue or Pink
The foam filters can be washed and reused. They can trap larger particles, such as pollen or heavy dust. The "Travel Filter" is useful for cutting down bad smells (e.g., when cleaning a cat litter box). It is also helpful for keeping moisture within the breathing zone in a very dry environment, such as during a long flight.
PS: This filter is for comfort purposes, not for air pollution or PM2.5.
