Putting Nebia by Moen to the Test

Putting Nebia by Moen to the Test

Wondering how Nebia by Moen compares to other atomization-like showers on the market? Here’s what Tom Murphy, Nebia’s Head of R&D, has to say:

“Compared to other atomization-like showers on the market, Nebia’s droplets are smaller, creating a more immersive, spa-like sensation. Our droplets also travel faster, providing more rinsing power per unit of water consumed. Finally, small droplets cool off faster than larger ones, but we’ve custom-designed the Nebia by Moen spray nozzles themselves, as well as their spatial arrangement, to ensure thermal comfort for all users.”

For Nebia by Moen, we think we’ve perfected the ideal combination of droplet size, spray pattern, and droplet velocity, resulting in our most advanced shower yet. Read on to find out how we accomplished this and how Nebia by Moen stands up to the competition.

Spray sensation

At the core of all three Nebia shower products—Nebia 1.0, Nebia 2.0, and Nebia by Moen—are atomizing spray nozzles that produce smaller, faster droplets than conventional showers. Nebia by Moen water droplets are larger than Nebia 1.0 and Nebia 2.0 water droplets (to improve temperature and rinsing), while still much smaller than those of regular and atomization-like showers (see Table below). The result is our signature Nebia spa-like sensation, which feels like an enveloping and immersive cloud of water droplets, steam, and air.

Body coverage

We generally define Body Coverage as the amount of a showerer’s body that is contacted by the spray. In the lab, we measure body coverage using the EPA WaterSense coverage test, which measures how much water from a shower falls into each of several concentric rings at a distance of 18” from the showerhead. At this 18” distance, Nebia by Moen covers a diameter of 20”, twice that of a similarly sized conventional 8” showerhead, and 2.5x the coverage of the atomization-like showers Hansgrohe Powder Rain and Delta H2OKinetic.

Rinsing effectiveness

Nebia by Moen provides comparable rinsing power to other atomization-like showers despite using about 45% less water (see Table above). We can measure rinsing effectiveness using the EPA WaterSense Spray Force test, the Nebia-designed Rinsing Efficiency test, or anecdotally by talking to users. We’ve done all three and Nebia by Moen passed with flying colors. Below Tom walks us through his custom-designed Rinsing Efficiency test.


Nebia by Moen is Nebia’s warmest shower yet, accomplished primarily by increasing the size of the water droplets by about 17% in diameter (61% in mass), thereby significantly increasing their ability to retain heat. We measure a shower’s thermal performance in the lab using Manny, our thermal mannequin. Manny is equipped with 32 temperature sensors which give us an objective indication of how warm a shower is.


We designed the Nebia by Moen spray nozzle array to keep a user’s entire body as warm as they need, again using far less water than the competition (see Table). Moreover, the optional handheld wand increases midsection temperature by an additional 1.0°C for users who like their showers piping hot. 🔥
