The candle

How it works

Leave the flame

As the candle burns, wax particles leave the flame and move into the air around it. Each one carries a trace of silver.

Attract

In the air, those wax particles attract other particles, the ones already floating there.

Contact

Where the wax touches another particle, the silver inactivates it. That starts the moment they meet.

Fall

Joined together, the particles grow heavy and fall out of the air. It works only while the candle is burning.

Glow Guardian is tested as a complete system. Current evidence supports the performance of the finished candle, while research continues to quantify how much each individual pathway contributes.

Read the testing

Then we measured it.

What we found

In controlled room-sized chamber testing, every tested virus and bacteria surrogate showed at least 87.9% net reduction after one hour and at least 99.15% after two hours.

A fair comparison

Every test ran next to an untreated control chamber. We only count the difference between the two.

Tested as you burn it

The finished candle, lit, as one whole thing. Not the wax alone, and not the silver alone.

Who tested it

ARE Labs, 2024 to 2025, using standard air-cleaner test methods (AHAM and ASHRAE 241). The full reports are on the science page.

Whole rooms start with what you burn in them.

One wax blend, one vessel, three cotton wicks. No paraffin, no phthalates, no dyes, no synthetic fragrance.

Good to know

Questions before you choose a candle.

What is a Glow Guardian candle made of?

A 12 oz (340 g) blend of soy at 55%, coconut at 35% and beeswax at 10%, with three lead-free cotton wicks, in a matte cream glass jar with a gold metal lid. Scent, where there is any, comes from essential oils. There is no paraffin, no phthalate, no dye and no synthetic fragrance. The wax also carries a trace of metallic silver at roughly 10 micrograms per gram.

How does it work?

Wax particles leave the flame, each carrying a trace of silver, and attract other particles in the air. Where the wax touches another particle, the silver inactivates it, and together they grow heavy and fall. It works only while the candle is burning. This is not a device that treats a room and then stops.

Glow Guardian is tested as a complete system. Current evidence supports the performance of the finished candle, while research continues to quantify how much each individual pathway contributes.

What was tested, and by whom?

Chamber testing was carried out at ARE Labs between 2024 and 2025, under AHAM and ASHRAE 241 air-cleaner protocols. In controlled room-sized chamber testing, every tested virus and bacteria surrogate showed at least 87.9% net reduction after one hour and at least 99.15% after two hours.

Every figure is net of untreated control chambers. The lab reports are on the science page.

Is the silver safe to breathe?

The maximum airborne silver measured while the candle burned was 1.01 ng/m³ — at least 800× below the NIOSH recommended exposure limit and at least 9,900× below the OSHA permissible exposure limit. It was measured under Good Laboratory Practice conditions in a residential-room simulation against a control candle, by filter sampling and ICP-MS.

How long does one candle burn?

About 40 hours, at roughly 8 grams per hour. One candle is suited to a room of about 150–250 ft²; in larger or open-plan spaces, use more than one. Trim the wicks before each burn, use on a stable level surface, and keep away from drafts, children and pets.

How strong is the scent?

Deliberately restrained. Most of this category competes on throw strength. This one does not — the scent is meant to be noticed when you walk in and then leave you alone. If you would rather have none at all, 07 Tranquility is unscented.

Which scent should I choose?

It comes down to taste. All four share the same wax, wicks and jar. Only the essential oils change, and 07 Tranquility has none at all.

What does shipping cost, and can I return a candle?

$3 a candle, free on three or more. Orders ship within three to five business days. Returns run 30 days from delivery, unused and in the original packaging.

Shipping and returns has the full details.

Is a Glow Guardian candle non-toxic?

It is a non-toxic candle in the sense that word is used for candles: no paraffin, no phthalates, no dyes, no synthetic fragrance, and lead-free cotton wicks. The wax is soy, coconut and beeswax, and the scent, where there is any, is essential oil. The wax also carries a trace of pure silver. The silver that reaches the air during a burn was measured on its own, and those figures are on the safety page.

What is an air-purifying candle?

A candle designed to do more than simply scent a room. Glow Guardian is tested against airborne microbial particles in controlled chamber conditions, as a complete, finished candle. It works only while the candle is burning, and it is not a medical device or a substitute for ventilation. The lab reports are on the science page.
