FAQ
What is the difference between atomizer types?
A standard atomizer delivers about 0.1 ml per spray (10 sprays/ml) and is found on most designer bottles. Fine mist atomizers deliver about 0.08 ml (12 sprays/ml). Heavy spray atomizers deliver 0.125 ml (8 sprays/ml). This matters because spray count recommendations from our Cologne Spray Count Guide assume a standard atomizer.
How much cologne can I bring on a plane?
TSA allows up to 3.4 oz (100 ml) per container in carry-on. The practical move is a 5-10 ml travel atomizer, which gives you 50-100 sprays - more than enough for any trip. Decant from your main bottle at home to keep the full-size bottle safe and out of your luggage.
How do I refill a travel atomizer?
Most travel atomizers refill by removing the main bottle cap, placing the atomizer over the spray tube, and pumping up and down. Some have a twist-to-fill mechanism. Avoid pouring directly to prevent evaporation and spillage. Fill to about 80% for pressure changes during travel. Our Bottle Lifespan Calculator tracks your main bottle usage so you know when to refill.
