Plenty of products claim to “purify your air.” Very few can show you the test. We built Glow Guardian around one idea — that a wellness claim should be backed by evidence — so before we said a word about clean air, we had it independently tested.
The test
An outside laboratory (ARE Labs) evaluated Glow Guardian in a sealed environmental chamber using FDA-recognized air-purifier methods. Live bacteria and virus surrogates were released into the chamber, then air samples were measured over time as a Glow Guardian candle burned — and compared against an untreated control run.
The result
Airborne levels fell steadily throughout the evaluation. Viral surrogates dropped quickly once the candle was lit, while bacterial levels kept declining across the test — reaching up to a 99.99% reduction of the bacteria tested by the end. One way to picture it: for every ~10,000 airborne units measured at the start, about 1 remained.
(Results vary by organism and reflect controlled chamber conditions.)
What it means at home
While it burns, the candle’s natural formula helps reduce airborne particles in the room around it — a calmer, fresher-feeling space, made with naturally derived ingredients rather than filters, cords, or harsh chemicals.
And it’s made to be safe
The trace ingredients in each candle are kept well below OSHA, NIOSH, and EU airborne reference limits, and independent testing confirmed safe airborne levels during continuous burning — so it’s a comfortable fit for homes with kids and pets.
We publish the proof
We’d rather show than tell, so the full lab reports and methodology are available on our Science page. That’s the whole point of Glow Guardian: clean ingredients, real testing, and nothing to hide.
