- ungzd 8y agoThe first one does not have filter so it will count large particles, such as regular dust, too. This does not makes it useless but this should be taken into consideration.
- ungzd 8y agoSorry, seems that similar sensors doesn't need filters and detect particle size ranges by intensity of scattered light. However, I can't find information about what sizes this sensor detects.
