One thing we are going to be rolling out to our testing process is using more sensors and tracking every 1 second instead of the 2 minute max that the Purpleair API restricts us to.
I have been using this data for the last few months and it really helps improve accuracy.
With regards to PM1 - PM10, most of my data suggest that time to remove these is directly correlated although PM1 takes longer than the larger particles to achieve zero levels.
Other studies I have seen suggest that the filter grade E11 maximises the overall CADR you can achieve for a device like an air purifier which is why Air Fanta uses it in their https://housefresh.com/airfanta-3pro-review/
•How is the incense smoke measured at PM1.0, PM2.5, and PM10.0 in the tests? The time it takes seems like it only accounts for PM1.0 particle sizes, which should be the most conservative. But if someone were interested in data for designing a filter for PM2.5 or PM10.0, I think the test results should show these other particle sizes too.
•What is average particle size from incense smoke? It's min/max range?
•Have you considered DOP testing and a calibrated photometer for testing filter efficiency?

It is a good idea and is something I am looking into. Whilst not perfect, you can look at carbon amount in lbs can be helpful with overall particle CADR. nnMost devices on the market are only meant for minor odors and gasses with the need to go for specialist devices with more carbon like IQAir healthpro Plus/GC gas.

It would be great to add VOC testing to your methodology. I spent a lot of time researching devices only to find out most of them do almost nothing for VOCs.

I need to get this information on the site when I have a chance!
