About FreezAir
FreezAir exists because the portable-cooling market splits into two worlds that rarely talk to each other: big-box compressor units reviewed by testing labs, and direct-to-consumer personal coolers reviewed by almost no one with a consistent standard. We cover both with a single ruler.
What we do
We research, score and compare portable air conditioners, evaporative coolers and personal cooling devices. Every product receives the same weighted rubric — cooling 30%, value 20%, noise 15%, energy 15%, build 10%, ease of use 10% — described on our How we test page. Where a manufacturer does not publish a spec, we print “not disclosed” instead of guessing.
Our honesty rule
An evaporative cooler is not an air conditioner, and we never pretend otherwise. Reviews state plainly which technology you are buying, what it can do, and what it physically cannot. Our technical analysis pieces check marketing claims against thermodynamics.
What we cover, in numbers
FreezAir publishes in English, German, French and Spanish, and every product page exists in all four. As of August 2026 the site carries ten devices — nine coolers scored on one rubric, plus one air purifier scored on a separate one, because a purifier cools nothing and it would be meaningless to grade it on cooling.
Alongside the reviews there are seven calculators (BTU sizing, room area, running cost, power draw, noise comparison, temperature conversion and load), buying guides organised by situation rather than by brand, and technical analyses that put one marketing claim at a time through the arithmetic.
What the rubric actually catches
Weighting disclosure is not a stylistic choice; it is what separates the scores. Of the nine coolers we cover, three sellers publish a wattage and two publish a decibel figure. The rest describe themselves as whisper-quiet and leave the number blank. That gap is most of the distance between a 7.5 and a 5.7 on this site.
The same discipline applies to prices. We record the displayed price, the reference it is discounted from, whether that reference moves between package tiers, and every pre-ticked add-on. On one checkout the two-pack advertised at 249.98 completes at 276.95 once protection, shipping and tax are added — about 11% above the number on the button. That arithmetic belongs on the page, not in the footnotes.
We correct in public
Getting something wrong is normal; hiding it is not. When we find an error in our own work, the correction goes on the page that carried it, in the open.
Two recent examples. We described one device as a 2-in-1 that cools in summer and heats in winter, and scored it partly on that basis. It does not heat — the current offer makes no heating claim and the published specification lists no heating element. The review now says so in its opening paragraph and the score moved from 7.2 to 7.0. Separately, we had published an “up to 8 °C” figure for another cooler that we could not trace to the manufacturer or to the checkout. It came out, and the brand’s own published specification — 5 V at 1.0 A, about five watts — went in instead.
What we are not
We do not make, stock, ship or sell any of these devices, and we take no orders. Payment, delivery, guarantees and refunds are handled entirely by the seller. We are not a laboratory either: our reviews are research-based, built from what manufacturers publish and what checkouts actually charge, and every figure is attributed to whoever stated it. Where a claim cannot be checked, we say that rather than repeat it.
