Hello,

I have been researching pollen.
Normally pollen can not reach the lower respiratory tract of the lungs.
On the other hand the pollen has the fact of being hooked to the PM, the PM are able to reach the lower parts of the lungs.
This is what causes allergies due to pollution.
My logic tells me that the pollen can come to foul the sensor.
A verify but it seems logical.

In astronomy, I use an optical/barlow/DO/... cleaning product (without solvent, bio), when I have to recover my AQI,
I will test this product on the old sensor SHARP.

Excellent day.
