# BreatheSafeAir > Independent air quality testing by Ethan Brooke. I have reviewed over 110 air quality monitors, purifiers, masks and respirators since 2019, scoring each against a published methodology. I do not run sponsored reviews and I am not paid for scores. Every score on the site follows the same tiers, so a 7 means the same thing in one review as it does in the next. Where I cannot verify something myself, I say so and lean on third-party lab results instead. ## How to read this site - [Methodology](https://breathesafeair.com/methodology/): How every score is calculated, including the tier tables for each device category. - [About Me](https://breathesafeair.com/about-me/) - [Disclaimer & Ethics](https://breathesafeair.com/disclaimer/) ## Tools - [Air Purifier Room Size Calculator](https://breathesafeair.com/tools/air-purifier-room-size-calculator/) - [Mask & Respirator Particle Reduction Calculator](https://breathesafeair.com/tools/mask-particle-reduction-calculator/) - [What Air Quality Monitor Do You Actually Need?](https://breathesafeair.com/tools/which-air-quality-monitor/) ## Buying guides - [10+ Best Air Quality Apps and AQI Apps in 2026](https://breathesafeair.com/best-aqi-apps/) - [28 Best Reusable Face Masks - Cambridge Mask Alternatives](https://breathesafeair.com/best-reusable-masks/) - [Best Fine Dust Masks in Korea](https://breathesafeair.com/best-fine-dust-masks-in-korea/) - [Best Kids Masks: 13 Best Certified Facemasks for Toddlers, Children & Teens](https://breathesafeair.com/best-kids-masks/) - [Cambridge Mask vs Airinum vs Vogmask](https://breathesafeair.com/cambridge-mask-vs-airinum-vs-vogmask/) - [Essential Guide to Respirators in Australia](https://breathesafeair.com/essential-guide-to-respirators-in-australia/) - [Flow 2 vs Atmotube Pro - Best Portable Air Pollution Monitor](https://breathesafeair.com/flow-2-vs-atmotube-pro/) - [How to Disinfect & Clean Respirators](https://breathesafeair.com/how-to-disinfect-and-clean-respirators/) - [How to Understand AQI (Air Quality Index)](https://breathesafeair.com/how-to-understand-aqi-air-quality-index/) - [Mask Ratings - N95 vs FFP2 vs KF94 vs KN95](https://breathesafeair.com/mask-ratings/) - [The Best Radon Monitors I’ve Tested.
