With a MERV10 filter? Advertised as removing smoke?
Here is some actual MERV data:
https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating
MERV 10 is not guaranteed to remove sub-micron particles at all. You need at least MERV 11 for that. [0] Having personally tested some filters in wildfire smoke with a little handheld particle counter, I believe in actual specs. If there isn’t an actual spec referencing a defined standard, then it does not matter how many platitudes about smoke are given — the device is unlikely to work.
[0] And you probably want MERV 13-16 to get to the air purifier sweet spot where flow times removal rate is large and where cost is reasonable. But if you’re going to err, err in the direction of HEPA so that particles actually get removed.
