The range
Choose your daily mould-defence setup.
Need a diffuser? The Protection Kit has the bottle and the diffuser together. Clean existing mould and address moisture first. Fit the uncapped bottle to the waterless diffuser. Run daily: in bathrooms, 30 to 60 minutes after the shower; in bedrooms, each day.
Place the diffuser in a safe, dry spot on a stable surface, out of reach of children and pets, not in water or under a tap. Wipe any neat oil off surfaces and fabric.
Protection Kit

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!

Questions worth asking
The questions sceptics ask first.
How does it actually work?
Two of the six oils, clove (eugenol) and Litsea Cubeba (citral), are the primary oils active against mould: citral disrupts ergosterol biosynthesis in the mould's cell membrane, while eugenol acts on the membrane directly. The other four oils carry the vapour and slow evaporation. Full mechanism on the How Mould Works page.
What if it doesn't work?
Reply within 60 days with one photo. Refund same day. No return shipping. Keep the bottle.
How do I use it?
Diffuse daily in the room mould keeps showing up in. We email you our 6-page guide, Why Mould Keeps Coming Back, straight away, and you can read the full how-to guide any time. Want it tailored? Reply with a photo of your worst room and Ben sends back a plan written for it.
How fast does it work?
Fresher smell in a week. Patch behaviour takes two to four weeks of daily diffusion. That is why the refund window is 60 days.
Safe around kids and pets?
First Light is a natural essential-oil blend made for everyday home use. Use it as directed with the room ventilated, keep it out of reach of children and pets, and take extra care around cats, which process some plant compounds differently to people. See our full guide to using First Light around children and pets.
Stop scrubbing. Put First Light in the room.
60 days. Refund any time, for any reason, and keep the bottle. One email, one photo, refund the same day. No posting bottles back, no return postage, no form. The guarantee is on us, because we already know what First Light does: 99.2% reduction in Aspergillus niger (black mould) on direct contact, independently lab tested.
