Affiliate disclosure

Short version: some links may earn us a commission. Scores never move because of it.

Some links are affiliate links: if you buy through them, we may earn a commission at no extra cost to you. It never changes our scores.

Our scores and rankings come from a published formula applied to what each brand publishes. One sentence on method: we compare product pages, price tables, warranty terms and FDA documents; we don't run sessions in the chambers ourselves. A brand can't pay to change its position, and a chamber whose maker has no affiliate program is ranked exactly like the others.

Buttons that leave the site point to the brand's own product page, or to the dealer we read the price on. They are marked rel="nofollow", and become rel="sponsored" once a partnership is active.
