Jetpack's built-in visitor analytics. It records page views, referring sites, search terms, and outbound link clicks, and also carries the shared visitor-tracking library used by Jetpack Instant Search and WooCommerce Analytics.
Service URL: automattic.com (opens in a new window)
tk_ai
Stores a randomly-generated anonymous visitor ID so Jetpack's Tracks analytics library can link tracking events to the same visitor.
Session in wp-admin; up to 5 years on the frontend
tk_qs
Queues analytics events for Jetpack's Tracks library so none are lost if the page closes before they can be sent.
30 minutes
tk_tc
Used once per page load to work out which cookie domain the Tracks library should use, then removed as soon as it's read back.
Session (deleted immediately after use)
tk_aip
Stores a list of anonymous visitor IDs so they can be merged into one identity once a visitor is recognized.
Up to 5 years

@neil-comparettoJust finished listening to the latest HVAC School podcast with Aprilaire. One thing I wish they’d gone into a little more detail on is filter media loft—not the overall filter depth (3”, 4”, 5”, etc.), but the actual thickness of the media itself. We use Aprilaire filters in our company and have been really impressed with their quality and dust-holding capacity. It almost seems like they reach a certain pressure drop and then barely increase from there. Compare that to a typical thin-media pleated MERV 8 filter, which doesn’t seem capable of holding nearly as much particulate by weight. I’d love to see a Project Farm-style comparison of high-loft MERV 13 filters versus conventional thin-media pleated filters, measuring pressure drop against the cumulative weight of particulate captured. My suspicion is that high-loft media would exhibit a relatively flat pressure-drop curve over a much greater amount of accumulated particulate, while conventional thin-media filters would show a much steeper increase in resistance as they load. I’d love to see those curves plotted side by side. Is anyone aware of an existing study that’s looked at this? If not, who wants to take it on? https://youtu.be/RkjRKIRva58?is=NB11AhTC9dYsM5tX
