Armed with the facts, you'll be able to make an informed decision next time you shop for a plug-in freshener. Keep reading to get the full scoop on how these deodorizing devices are affecting your electric bill.
A Closer Look at Typical Electricity Usage
When shopping for an air freshener, one of the first things to check is its watts rating. This specifies how much power the device draws. Most plug-in fresheners are relatively low wattage devices, ranging from 1 to 10 watts.
For comparison, a typical LED light bulb runs around 5 to 8 watts. So air fresheners tend to draw about the same amount of electricity as a modest lighting fixture.
To estimate the actual energy use of an air freshener, you'll need to consider its wattage along with your usage patterns. Here are some examples of typical kWh usage:
- 5 watt freshener running 6 hours per day = about 1.5 kWh per month
- 10 watt freshener running 8 hours per day = about 2.4 kWh per month
So if used daily for scent control, even these small gadgets can add up to 10 to 20 kWh over a whole year.
How does this compare to other common household electronics? A plugin air freshener generally uses far less energy than major appliances, but more than tiny gadgets like phone chargers. For perspective:
- Laptop or desktop computer: 30 to 60 kWh/month
- LED TV: 15 to 30 kWh/month
- Game console: 5 to 20 kWh/month
- Smart speaker: 1 to 3 kWh/month
- Phone charger: less than 1 kWh/month
Clearly, air fresheners fall on the lower end of energy usage. But their electricity draw isn't completely negligible either. The next sections look at design factors that can influence their energy efficiency.
Design Factors That Impact Electricity Usage
While most air fresheners have similarly modest wattage ratings, their features and functionality can vary. Subtle differences in product design have an effect on electricity requirements.
One factor is the scent release method the product uses:
- Gel air fresheners - Absorb oil into a gel substrate and rely on passive diffusion. Lower energy needs.
- Cartridge air fresheners - Use a wick or membrane to diffuse oil. Modest energy needs.
- Spray air fresheners - Actively spray scent at intervals. Can have higher energy needs.
- Fan-driven fresheners - Use a fan to propel fragrance. Among the highest energy needs.
In general, models using passive scent diffusion will require less electricity than those with a motor or active scent dispersal. But the differences may amount to just a couple watts.
Features and Settings
Specialized features and settings can also impact energy draw:
- Nightlights - Convenience feature but adds illumination power needs.
- Multiple fragrance settings - More speed/power settings can increase energy use.
- Timer and auto shut-off - Can limit freshener runtime and save power.
- Motion activation - Only runs when detecting movement, saving energy.
When available, choosing lower fan speeds or intensities can potentially reduce electricity usage over time. And features like auto shut-off help limit waste when the freshener is not in use.
Usage Time and Patterns
Electricity usage is also linked to how often and for how long you run your air freshener:
- All day vs sporadic use
- Continuous operation vs timed intervals
- Usage in multiple rooms
Fresheners that run 24/7 in several rooms will obviously consume more power. But proper use aligned with scenting needs can curb excess energy consumption.
By understanding how these factors influence electricity draw, you can make choices to minimize usage. The following tips can further reduce your air freshener's energy footprint.
Tips for Reducing Your Air Freshener's Electricity Use
Small changes in how you select and use plug-in air fresheners can limit their electricity usage and your energy bill impact. Here are some smart tips:
Choose Low-Wattage Models
Prioritize air fresheners with wattages of 5 watts or under. Lower wattage directly correlates to lower electricity consumption. Brands like Glade, Air Wick and Febreze all make models 3 watts or under.
You may have to check the specifications or packaging closely to find this information. But choosing a 1 watt over a 10 watt model could reduce energy use by over 80% with similar scent performance.
Use Features Like Auto Shut-Off
Many modern air fresheners have programmable timers or auto shut-off capabilities. Using these features to limit runtime prevents electricity waste when scenting isn’t needed.
Fresheners with motion sensors that activate only when they detect movement are another energy-saving option. Brands like Air Wick, Ozium and Eco-Me make motion-sensing models.
Unplug When Traveling or for Long Periods
Unplugging your air freshener when away from home for days or weeks provides an easy way to eliminate phantom load.
Even when turned off, plugged in devices draw a small amount of power. So get in the habit of unplugging fresheners for vacations, business trips or seasonal homes.
Use Sparingly in Little-Used Rooms
Limit freshener use in spaces like closets, storage rooms or basements that have minimal foot traffic. These infrequently visited areas need less regular scenting than high-use rooms.
Strategically using air fresheners where they're needed most will get the job done with less energy.
Follow Proper Usage Instructions
To optimize efficiency, closely follow the product instructions. This includes replacing cartridges or pads on schedule and using appropriate fragrance settings for room size.
Taking the time to properly maintain your fresheners ensures they run as designed. It can prevent issues like blocked vents that may increase electricity draw.
Estimating Cost and Environmental Impact
To make the most informed purchase decisions, it helps to understand plug-in air fresheners' potential cost and environmental footprint. Here are some key points to consider.
Electricity Cost Estimates
Based on average residential electricity rates around 15 cents per kWh, here are some estimates on operating costs:
- 5 watt freshener running 5 hours a day: around $2 annually
- 10 watt freshener running 8 hours a day: around $7 annually
For most households, this only amounts to a few dollars per year to run an air freshener. But costs can escalate with higher wattage models and increased use.
Bigger Energy Picture
Viewed collectively across all US households, the energy consumption and emissions of air fresheners add up:
- 5+ million tons of greenhouse gas emissions annually
- Over 4 billion kWh of electricity used yearly nationwide
So while minimal at the individual level, collectively these small gadgets do have larger environmental impacts.
