I have that machine. It seems better at filtering chemicals and VOCs but not great at filtering particulates. It gets rid of odors very well but my PM2.5 meter barely budges.

I have IQAir HyperHEPA filters, plus whole-house AprilAire HEPA filters on the HVAC equipment in the attic. I’m fine on particulates.

Where I need extra help is with VOCs in certain locations. Like, in or near bathrooms. Or the cat litter boxes. IQAir does sell their GC line for that, and we have a couple of those. But the activated carbon filter media is super expensive. And these things are huge. Like, bigger than a dorm refrigerator.

So, I welcome an alternative that does VOCs well.

Yeah, it's a completely different kind of air purifier than the "tape a HEPA filter to a fan" ones, which is why it costs $1,000 instead of $150.

Which PM2.5 meter do you have? I’ve been looking to buy one and AirThings keeps coming up.
