Summertime is one of the most popular seasons for road-trip getaways with family and friends. But anyone who's been road-tripping knows that, before long, certain foul smells can start to take over the vehicle. No one wants lingering odors from sweat, pets, leftover food, or someone in the back seat passing gas to ruin the vibe of their weekend escape, so we've created this thorough guide to help you pick the right air fresheners to keep your car smelling fresh all summer long.

Types of Vehicle Air Fresheners

When buying an air freshener for your car, one of the most important factors to consider is how the scent will be dispensed. Today, popular options include:

• Hanging Air Fresheners
• Reed Diffusers
• Vent Clips
• Electronic Aroma Diffusers
• Scent Cans
• Sprays

Let's examine the pros and cons of each of these types.

Hanging Air Fresheners

Traditional hanging air fresheners are about as simple as they come. A piece of fiberboard or cardboard is treated with fragrance oil and hung out to allow the scent to dissipate. 

Pros of Hanging Air Fresheners:

• Easy to set up.
• Zero maintenance.
  
• Inexpensive.

Cons of Hanging Air Fresheners:

• Single use: Once a hanging air freshener has lost its potency, you're left with a decorative piece of cardboard.
• Short-lived: Hanging air fresheners generally last 2-3 weeks before losing their scent.
• Unnecessary waste: Other types of air freshener last significantly longer or can be reapplied once the scent has dissipated.

Reed Diffusers

Reed diffusers are one of the easiest, oldest, and most effective ways to dispense aromas. They usually consist of a vial or jar filled with fragrance oil, and a perforated cap through which reeds are inserted to soak. Once the reed has absorbed enough fragrance oil, it will naturally diffuse it throughout your car. 

Pros of Reed Diffusers:

• Refillable.
• Easy to set up: Fill, place, and forget until it's time for a refill.
• Low maintenance.
• Long-lasting: Depending on the size of your diffuser, each fill-up can consistently deliver scent for up to two months.
• Compatible with most fragrance oils, including all Urban Encounter Scents for Diffusers.
• Aesthetically pleasing: Reed diffusers come in a wide variety of gorgeous designs to fit your tastes. Some can even be hung on your rear-view mirror or attached to your AC vents.
• Environment friendly: Most, if not all, waste associated with reed diffusers is either biodegradable or locally recyclable.
  

Cons of Reed Diffusers:

• Potential for mess: Filling a reed diffuser always involves the risk of spills and wasted fragrance oil.
• Replacement reeds: Anytime you need to refill your diffuser, and especially when changing scents, you also need to replace the reeds. Not every diffuser has reeds readily available that are an exact fit, which means you'll likely need to cut generic reeds to fit your model.

Vent Clip Air Fresheners

Vent clip air fresheners work by using the airflow from your car's AC system to direct fragrance particles throughout the cabin as they evaporate.

Pros of Vent Clip Air Fresheners:

• Easy to set up: Simply attach the air freshener to your car's air-conditioning vent and voila!
• Zero maintenance.
  
• Uses your car's air conditioning to dispense fragrance, resulting in a more even distribution throughout the vehicle.

Cons of Vent Clip Air Fresheners:

• Single-use: Most vent clip diffusers are single-use and cannot be refilled or locally recycled. While some manufacturers offer mail-based recycling programs for their products, not everyone has the time or resources needed to participate in these programs, resulting in unnecessary plastic waste in landfills.
• No AC = Less Freshness: If you're not actively running your car's ventilation system, you're not getting your money's worth out of your vent clip air fresheners.
• Short-lived: Most vent clip air fresheners only last up to 30 days, with many losing strength well before that.

Electronic Aroma Diffusers

While electronic aroma diffusers come in a wide variety of shapes and sizes, they largely fit into two broad categories: Waterless and Water-Based.

One method for waterless fragrance oil diffusion is to use heat. Heat-based waterless diffusers work by placing the essential oil in a tray or container directly above a heating element and allowing the process of evaporation to diffuse the scent throughout your home or vehicle. While this very traditional method can be quite effective, it also comes with some significant drawbacks. First of all, heating certain essential oils can alter their molecular structure, change or lessen their scent, or cause them to become volatile in other ways. Secondly, whenever a heating element is involved, the risk of fire becomes heightened. This is especially true if a heat-based diffuser is made cheaply with poor-quality parts. As such, we do not recommend heat-based diffusers in vehicles.

Cold-air waterless diffusers, like the portable models offered on MasterCreationsInc.com, use ultrasonic vibrations instead of heat to atomize your essential fragrance oils and diffuse them throughout your space in bursts. This method is ideal because the essential oil's aroma remains pure while being evenly and consistently dispersed throughout your home or vehicle.

Unlike their waterless counterparts, water-based diffusers require that you dilute your essential oils with water to a ratio specific to that model of diffuser. This means that, while your oils may last a bit longer, you may also need to run your diffuser for a longer period and at a higher intensity to achieve your desired results.

Pros of Portable Waterless Aroma Diffusers:

• Consistent performance: Unlike vent clips, scent cans, and hanging air fresheners, cold-air waterless diffusers never lose their potency and deliver a pure aroma experience every time.
• Travel-Friendly: Our portable diffusers are rechargeable and fit in the cupholders of most vehicles.
  
• Refillable: All of our portable models include a refillable oil bottle and thread directly with our 15 ml Urban Encounter Scents for Diffusers.
• Intensity Control: Change how frequently or intensely the diffuser runs at the press of a button.
  
• Works on your schedule: Our portable diffusers can be powered on or off manually or set to shut off automatically after a time of your choosing.
  
• Low maintenance: Once you fill and charge your diffuser, upkeep is minimal. If you ever notice your diffuser's output dipping or stopping altogether, simply run a small amount of rubbing alcohol through it on high settings for 10-15 minutes. Be sure to rinse all alcohol out of the refillable bottle before adding more oil.
  
• Long-lasting & economical: With most of our portable models, a single fill-up can last up to 90 days when used during commutes at medium settings.
• Environment-friendly: By being refillable, our portable diffusers significantly reduce single-use plastic waste. Furthermore, most, if not all, waste from packaging for our diffusers and diffuser refills can be locally recycled.

Cons of Portable Waterless Aroma Diffusers:

• Needs to be charged.
• Needs to be cleaned periodically if performance wanes.
• Potential for mess: Refilling the diffuser involves a small risk of spilling and wasting fragrance oil. Additionally, the diffuser should be kept upright to prevent leaking.

Scent Cans

Scent cans work similarly to reed diffusers by soaking and partially submerging a piece of fiberboard in fragrance oil stored inside a tin can. The user then opens the can's vented lid, which allows the scent to disperse naturally from the piece of fiberboard.

Pros of Scent Can Air Fresheners:

• Easy to set up: Open the lid and place the can under your seat or in a cupholder.
• Strong aroma: When first opened and for days after.

Cons of Scent Can Air Fresheners:

• Single-use: Most scent cans are single-use, and only portions of the product and its packaging can be recycled locally.
• High potential for mess: Scent cans are essentially a semi-open container of fragrance oil in your car, and can be prone to spilling and tipping over if not properly secured
• Short-lived: While some scent cans are advertised to last up to 60 days, actual performance can vary wildly due to environmental conditions, with many losing their potency much sooner.

Air Freshener & Odor Eliminator Sprays

Air freshener sprays are a tried-and-true method of keeping your ride smelling great and stopping foul odors. That being said, not all air fresheners are created equal. Water-based sprays deliver a much subtler fragrance that dissipates quickly, while oil-based sprays, like BluntPower or Fast & Furious, offer a much stronger aroma that can last for days with just a few sprays. Either can be effective, but at Master Creations, we've always believed that concentrated oil-based sprays are the superior choice.

Pros of Oil-Based Car Sprays:

• Made for Travel: Our compact 1.0 & 1.5 oz. sprays are perfectly sized to fit in glove compartments, pockets, and purses.
• A little goes a LONG way: 2-3 sprays of BluntPower or Fast & Furious Odor Eliminator in your car will instantly get rid of any unwanted smells and replace them with a strong aroma that lasts for days!
• Versatile: Our air freshener and odor eliminator sprays can be used in the open air or on any cloth surface in your vehicle. You can also spray your cabin air filter for a more constant scent experience.
• Tailored to you: Want a milder scent experience? Just use one small spritz. Need to knock out something foul or give your car a long-lasting scent? 2-3 sprays will have you covered! You have total control.
  
• Most economical: Because you only need 2-3 sprays to get the job done, you'll use significantly less of our product over time compared to other leading brands. Some users have even reported that a single 1.5 fl. oz. bottle of BluntPower Odor Eliminator lasted them more than a year!
  
• Environmentally friendly: We package our air fresheners and odor eliminators in durable, non-aerosol spray bottles that feature high recycled plastic content and are easily recyclable themselves.

Cons of Oil-Based Car Sprays:

• Residue: All oil-based air freshener and odor eliminator sprays leave a small amount of residue on the surfaces they're sprayed over.
• Need to respray: Unless you're spraying your cabin air filter, you'll likely need to respray your car every few days to maintain a consistent aroma.
