Scrubbing failed. This kills it.

You wiped. It came back. It always does, because mould is in the air, not just on the wall. First Light kills the mould and keeps working in the air, so it stops coming back. Lab tested. 100% natural. 60-day money-back.

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.

Easy to shop with and product came quickly.

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.

Very prompt service and FAQs are very useful.

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!

Shopping experience was great and speedy delivery!

Beautiful product! Everything about the brand from the luxe packaging to the functionality of the oils is very considered down to the smallest details. I now have 2 of the waterless diffusers and they are so much easier to have going than the water ones (constantly having to top up with water and also it adds more moisture to the air which isn't ideal). The oil blend smells amazing and makes the air feel fresh. I'm looking forward to seeing the difference it makes to the recurring mold growth in our house.

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 antifungals: 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.
