While we used three main testing categories to evaluate the best spray bottles, we had to test each category multiple times with different types of liquid. Some handled thicker liquids well, while others could only handle the consistency of water. Our three categories were durability, design and application and we were able to make our top selections based on them.
Durability: Spray bottles can take some abuse over time, so you need one that will withstand bumps, falls and intense spraying and still work effectively. Of course, glass bottles are always prone to breaking when dropped at higher elevations, but they should be able to remain intact when dropped at a couple of feet high. Durability was also tested with the spraying mechanism. The spray bottle received a lower score if any liquid leaked out of the sprayer itself and received a high score if no liquid came out of the bottle after several minutes of spraying. The overall durability of a spray bottle was determined by the bottle itself and how well it help up after intense spraying.
Design: The design of a spray bottle is an underrated aspect. You want a bottle that holds enough liquid without you having to constantly refill, but it also can’t be so big that it’s too heavy to use at first. The best spray bottle should fit in your hand easily and the trigger should be simple to reach and pull with minimal effort. We looked closely at the design of every spray bottle we evaluated and the score it received weighed heavily in our overall score.
Application: We looked at a few different things when giving a score for the application category. One was how easy it was to spray liquids of different consistencies. Another was how the spray tube fit inside the bottle and how much liquid was leftover in the bottle when it would no longer spray. And most importantly, we wanted to see if any liquid leaked out of the spray head, the trigger or the cap when using it. This may be our third category in the priority chain that we evaluated, but it was actually weighed just as heavily as durability and design in our overall score.
