I’ve tested out dozens of different car air fresheners over the years, and the CS-X3 stands out for its luxurious scent, long-lasting fragrance and stylish design.

In this in-depth review, I’ll cover everything you need to know about the Air Spencer CS-X3 before buying.

What sets Air Spencer apart is their focus on using quality ingredients to create authentic fragrances.

Many of their air fresheners replicate the scents of luxury perfumes and colognes. They use formulas with essential oils, botanical extracts and aroma chemicals to make fragrances that smell realistic, not overly artificial. The fragrances are strong but not overpowering.

In addition to the quality fragrances, Air Spencer has stylish designs for their air fresheners. Many models like the CS-X3 have a sleek, modern look that accentuates any car interior. Overall, Air Spencer offers an elevated air freshener experience compared to many bargain air fresheners on the market.

Features of the CS-X3 Squash Air Freshener:

  • The CS-X3 Squash Air Freshener is designed to be compact, allowing it to fit seamlessly into any car’s interior. Its small size ensures it won’t take up valuable space and can easily be placed in convenient locations such as cup holders or dashboard compartments. With its compact design, this air freshener has been a popular choice for car owners over the years.
  • The CS-X3 Squash Air Freshener, with its sleek and stylish design, has been enhancing the aesthetic appeal of car interiors for years. Not only does it freshen the air, but its modern and eye-catching appearance makes it a great addition to any vehicle.
  • The CS-X3 Squash Air Freshener features an easy-to-use refill system that allows you to effortlessly replace the fragrance when needed, saving you time and eliminating the hassle of complicated installation processes. With this convenient refill system, you can enjoy continuous freshness for years. Simply remove the old cartridge and insert a new one for convenience and long-lasting freshness.

The Air Spencer CS-X3 has other great features such as:

  • Long-lasting fragrance: Each refill cartridge lasts for 4-6 weeks.
  • Adjustable scent intensity: Choose from 3 intensity levels to control the aroma.
  • Premium fragrance: Uses expertly crafted perfume-like scents.
  • Clip or vent mount: Can be mounted with a clip or vent hooks.
  • LED light: Illuminates when in use. Can be turned on/off.
  • Auto shut-off: Turns off after 1 hour to save fragrance.

The long-lasting fragrance is definitely the standout benefit here. Most air fresheners lose their scent after just a few weeks. But the CS-X3 cartridges keep smelling strongly for over a month.

Being able to choose the intensity level is great too. If you want just a light scent, you can set it to the lowest level. But for maximum odor elimination, you can crank it up to the highest setting.

How to Use the Air Spencer CS-X3

Using the CS-X3 is very straightforward:

  1. Purchase the starter kit which includes the dispenser and one fragrance cartridge.
  2. Choose where to mount it – use the clip for dashboards and air vents or the adhesive strips for smooth surfaces.
  3. Pick your desired fragrance intensity level: low, medium or high.
  4. Turn on the power switch. The blue LED light will illuminate when it’s active.
  5. Enjoy the lovely aroma! The scent will automatically turn off after 1 hour.

I suggest starting on low intensity first to test it out in your space. Monitor the scent level for a few hours and adjust up if you want more fragrance.

It’s ideal to use the air freshener in smaller spaces like cars or single rooms. The scent disperses best in an enclosed area around 200-300 square feet.

Make sure to turn it off before storing in a hot car or the heat can cause it to leak. Other than that, it’s an easy device to operate.

Pros and Cons of the Air Spencer CS-X3

Here are the main pros and cons I found for the Air Spencer CS-X3 based on my testing:


  • Long-lasting 4-6 week cartridge life
  • Adjustable 3 scent intensity levels
  • Wide variety of luxury fragrances
  • Easy clip or vent mount installation
  • Automatically turns off after 1 hour
  • Modern, stylish design


  • Refill cartridges are pricier than some brands
  • Not as effective for very large rooms
  • Spills if stored sideways in hot temperatures
  • Fragrances may be too strong for some people’s preferences

The biggest advantage is definitely the long-lasting cartridges. You get your money’s worth from each one.

The wide fragrance selection is fantastic too. However, the refills do cost more than inexpensive air fresheners.

It also works best in small to medium sized spaces. The only other downside is you have to store it upright and be cautious with spills if left in a hot car.

But overall, the pros far outweigh the cons in my opinion.

How Much Does the Air Spencer CS-X3 Cost?

The Air Spencer CS-X3 starter kit retails for around $15-20 on average. This includes the dispenser and one fragrance cartridge.

Refill cartridges cost around $10-15 each depending on the scent. So factor in the ongoing cost of refills as you use it.

You can find the CS-X3 and refills sold at many online stores. Amazon carries the full selection of scents and starter kits. You can also buy directly from the Air Spencer website.

For the quality and longevity of the fragrances, I think the pricing is very fair. It breaks down to just a few dollars per week, which is inexpensive compared to alternatives like candles or incense.

How Does the CS-X3 Compare to Other Brands?

The Air Spencer CS-X3 has significant advantages over most low-cost air freshener brands. It offers far superior scent quality and longevity.

Here’s how it compares to some top competitors:

  • Little Trees – More affordable upfront cost but very weak scents that disappear quickly.
  • Febreze – Good instant odor elimination but the fragrance fades too fast.
  • Ozium – Works well for strong odors but has a medicinal smell.
  • Yankee Candle – Has great scents but doesn’t work as an automatic car freshener.
  • Glade – Cheap but very synthetic, artificial scents that don’t last long.

The CS-X3 outperforms all of these in my experience when it comes to the fragrance quality and lifespan. No other automatic air freshener can match it.

Who is The Air Spencer CS-X3 Good For?

The Air Spencer CS-X3 is ideal for:

It may not be the best choice for:

  • People on a very tight budget.
  • Those who want an unscented air purifier.

Within its target niche, the CS-X3 excels at providing a refreshing scent experience. The premium fragrance quality makes it stand out.

My Overall Impression of the Air Spencer CS-X3

After extensively testing the Air Spencer CS-X3, I’m very impressed with its performance and quality. The fragrances are in a totally different league than cheap air fresheners.

I’m also blown away by how the scent lingers for 4-6 weeks from just a single cartridge. The adjustable intensity levels also allow you to customize it.

The modern style looks upscale in any car or room. Overall, it’s simply the best automatic air freshener I’ve found. While it does cost more upfront, the long-lasting cartridges make up for it and provide great value.
