BEWARE OF THIS MAN. Meet Stan – the standard man. He's got it into his head that standard is something good. That everything better than standard quality is superfluous. For instance, if he was to buy air filters, he'd choose one of standard quality. He'd point to the A classification and think the 35% cleaning efficiency for an F7 filter was good enough.
His lungs would not think the same. Because if you realise the importance of good health, you understand that air that is only 35% cleaned isn't always good enough. Several of our filters achieve over 50% cleaning efficiency. Much better than standard, but Stan ignores that of course. Hopefully, you think differently.
