filters, verified programs, and one machine that is not a purifier
Twelve listings were filed under air purifiers. Ten of them describe a filter. The remaining two are not room air purifiers by their own words: an ozone generator and a refrigerator deodorizer, each kept in a group of its own and never set in a table beside the filter units. The site makes no statement about what any of these machines does to the air in a room.
Each row reads left to right in a fixed order. A filled cell means the listing states that requirement; a dashed cell means the listing is silent where the requirement could apply; an outlined cell means the requirement does not come up. Every cell is named in words beside the row.
Filter air purifiers
10 listings
Listings that name a filter. Seven of them print HEPA or H13 as a word, one prints HEPASilent, which the site does not count as HEPA, and four print AHAM. Coverage is printed on different bases: six give an area with no time attached, two give an area covered in a stated time, and two give no area at all. Figures on different bases are not one number, so the comparison table leaves coverage out and each card prints its own figure as worded.

An ozone generator
1 listing
The listing states an ozone machine, and its title calls it an ozone generator. The catalog filed it among the air purifiers. This site does not call it an air purifier, does not compare it with the filter units, and gives it no badge. The site says nothing about ozone in its own words; what follows comes from the published documents linked here. The U.S. Environmental Protection Agency publishes a page titled “Ozone Generators that are Sold as Air Cleaners”, which also states: “EPA does not certify air cleaning devices.” California’s regulation on Indoor Air Cleaning Devices, Cal. Code Regs. tit. 17, §§ 94800–94810, refers in § 94804 to an ozone emission standard of 0.050 ppm. Neither document is summarized further here.
The listing states an ozone machine of 48,000 mg, and its title calls it an Ozone Generator. This site says nothing about ozone in its own words; the documents regulators publish on ozone generators are linked in this group, above the card.

Questions about these listings
Is the ozone generator an air purifier?
This site does not call it one. Its listing states an ozone machine, and the catalog filed it among the air purifiers; here it sits in its own group and in no comparison, with the published documents linked beside it.
Why are the coverage figures not compared?
They are printed on different bases. Some give an area and no time, some give an area covered in a stated time, and some give none. The site will not turn those into one number, so each card prints its own figure as worded.
Does HEPA on a listing mean the site checked the filter?
No. HEPA, H13 and a percentage are the listings’ own words. What HEPA refers to is set out on the HEPA and H13 page with EPA’s description linked; the site checks nothing itself.
