The lab result sounds too good. Here is exactly what was measured.
An independent laboratory measured a 99.2% reduction in Aspergillus niger (black mould) on direct contact. That result does not describe the air. The air evidence is separate.

Evidence
Three pieces of evidence. Three different questions.
Contact test
99.2% reduction in Aspergillus niger (black mould) on direct contact.
Air research
In a 2022 UNSW Sydney lab-chamber study published in Antibiotics, essential-oil vapour cut 72% of viable Aspergillus spores in 10 minutes. That study used a different blend and a different test.
Home demonstration
Two bread rolls, two jars, same room, fourteen days. It is an observation, not a laboratory test.

Customer experiences
In their own words.
Selected experiences with First Light and the diffuser.
Love it! Smells so good and it’s like magic, I don’t get how it works so well but it does. It has really cleared up my bathroom mould drastically.
I love the smell. I love the packaging. I love that it’s stopping mould from growing in my bathroom sink and no mould has come back on the ceiling so far. I love the diffuser as well! Great battery life, lovely and compact and looks lovely and minimal and sheek (is that how you spell that word?) Will definitely get me more when I run out.
Love the scented aroma as it wafts through rooms and the product is living up to expectations with mould management. The diffuser is a great addition to the product bundle, and I will continue to use and recommend First Light!

What exactly was lab tested?
First Light was independently measured at a 99.2% reduction in Aspergillus niger (black mould) on direct contact.
What do I buy first?
Choose First Light if you already have a diffuser. Choose the Protection Kit if you want the oil and waterless diffuser together.
