Affiliate disclosure

Cold Cedar Co is reader-supported. Some links on this site are affiliate links: if you buy through one, we may earn a commission at no extra cost to you.

It never changes our rankings. Our picks follow performance, build quality, how a unit fits a real home, and value, not commission. We lead every guide with the cheapest setup that is good enough, which often earns us the least, and we only point you to a pricier option when it genuinely earns its place.

We have, or are pursuing, affiliate relationships with brands including Plunge, Ice Barrel, Sun Home, Sunlighten, HigherDOSE and Almost Heaven. See how we test. Nothing on this site is medical advice.
