Umm, probably all of them. As an industry standard, .0146 microns is actually pretty subpar. Here are three random products that are well within ozone limits, that remove much smaller particles than .0146
2 of them are less than $70(so 9 can be purchased for the price of 1 airdog). And @ .001 micron, 2 of them remove particles almost 7 times smaller than your .0146 micron third world technology... https://www.microncorp.com/energaire/
