Renée's Take · Jul 2026
How I Tested 7 Humidifiers
I tested 7 humidifiers from 7 brands across 8 safety checks, including Requires Chemical Tank Additives and Humidifier Technology Type. Every product was scored the same way: material safety first, then real-world performance and ease of use.
What I found: The top picks pass third-party safety verification and hold up in everyday use. The humidifiers I left off had unverified material claims, missing certifications, or hidden tradeoffs that matter day to day.
Here's what came out on top:

- 2.Dyson Purifier Humidify+Cool Formaldehyde PH04 · Dyson · 7.8/10 · $500
