Do you have any recs for the right filter and sensor?

Someone referred me to https://oransi.com/ and I purchased one of the large EJ120 models. I've had it running for a few days and my place no longer has a smell and the air just feels clean. It's bizarre.

Nice, thanks for the recommendation. Is the EJ120 very audible? Where do you place it? Like someone mentioned elsewhere, the spouse approval factor is relevant for what air filtration solution I go with... haha

Doesn't look like any of those have sensors, unless I missed that? I guess one sensor is your nose in this case, ha.

HEPA filters which include a claim for 99.97% filtration (HEPA is put on a lot of things that are much less useful) Honeywell makes good ones.

MPR 2800 furnace filters for the box fan contraption. 3M makes good ones. Your furnace might not appreciate how much they slow down flow.

IQAir monitors are unreasonably expensive and IOT nonsense, but still good.
