First Light is a six-oil essential-oil blend for airborne mould defence. Add it to a diffuser, a bowl in a cupboard, or a spray bottle, and the oils spread through the air. Mould starts as tiny spores floating in the air before they land and grow. Most mould products only work on the black patch you can already see. First Light works in the air, meeting the spores before they settle, so it helps stop mould coming back between cleans. Laboratory tested. 99.2% reduction in Aspergillus niger (black mould). In a separate lab chamber study, essential-oil vapour cut 72% of airborne mould spores in 10 minutes. Two of the six oils, clove and Litsea Cubeba, break the wall mould builds to grow. The other four carry them through the air, cover more species, and slow evaporation. Made for damp, still-air spots: bathrooms, laundries, wardrobes, bedrooms. Safe for daily use around kids and pets. 60-day promise: use it daily, and if it does not help your mould, send one photo and we refund you. Keep the bottle. No return, no postage. Every batch is quality tested for a pure, consistent blend with no synthetic additives. First Light is not a cleaner or disinfectant. Clean visible mould first, then use First Light daily to keep it from returning.
