Dyson's equipment supply an identical but a bit different dilemma. A few of its air purifiers, including the Dyson Pure Cool TP04 (at this time away from stock), which we also analyzed in prior many years, utilize a HEPA filter, but give no CADR. A Dyson spokesperson told us, "CADR as measured by some current methods isn't an exact illustration of a true property," and so the corporation has designed its individual testing strategies "to copy a far more real looking setting.
