About us

Stanley Alu, founder and editor. I founded QuietSpecs after running a product review blog, and I built it around the spec that is hardest to pin down. With noise, makers tend to quote the quietest setting they can find, or nothing at all. So I read the spec sheets, manuals and certification directories, quote each figure with the setting it describes, and say so plainly when a maker publishes none. I do not test products or measure decibels, and no brand pays for a place in a guide.

You can reach me at hello@quietspecs.com.

QuietSpecs is published under the name Datasheet Media. Every brand it runs follows one rule: products are compared only on figures their makers publish, quoted with the condition each one describes, and never on our own guesses.

We collect the manufacturer's published noise rating for every model, at the fan speed, mode or cycle the figure describes, and we say which one that is.

We check each figure against the maker's own spec sheet or manual, or a certification directory such as HVI or ENERGY STAR. When a maker publishes no noise figure at all, we say so.

Each pick shows its published figure and the maker's list price with the date we saw it, and we re-check prices as we update guides. Where a maker's own pages disagree with each other, we quote both figures.

Every page is written and edited by a person who read the source documents, with research assistance from software. Nothing is paraphrased from another review site: the sources listed under each page are the documents we actually read.

Guides and explainers carry a "How we reviewed this article" section with a dated entry for each substantive revision, so you can see when a page last changed and why. Prices show the date and time we last checked them.

When a maker revises a manual, replaces a model or publishes a new figure, the page is updated and the revision recorded.

We do not test products or measure decibels ourselves, and we never pretend otherwise. Makers rarely say how far away, or to what standard, their figures were measured.

So we treat published ratings as a way to compare models with each other, not as a promise about your room, and we tell you where a figure describes only the quietest setting.

If a figure, spec or claim here is wrong, email hello@quietspecs.com and we'll fix it and note the change on the guide.

When you buy through our links, the retailer may pay us a commission, and we show ads on some pages. As an Amazon Associate we earn from qualifying purchases.

That never changes the price you pay, and it never changes our rankings. We don't accept payment for a placement in a guide.
