2015 Nissan Murano Cabin Air Filter

Hey there, Murano owner! Having some trouble with the air quality inside your 2015 Nissan Murano? Maybe you've noticed a musty smell, weaker airflow from the vents, or just generally stuffier air. Chances are, your cabin air filter is due for a change. Don't worry, it's a common issue and often a pretty straightforward fix. Let's walk through some of the problems a dirty cabin air filter can cause and how to address them.

The Problem: Stale Air and Reduced Performance

A clean cabin air filter is crucial for maintaining a healthy and comfortable environment inside your vehicle. Its primary job is to filter out dust, pollen, mold spores, and other airborne contaminants from entering the cabin through the ventilation system. Over time, this filter becomes clogged with debris, leading to a variety of issues:

Reduced Airflow: A clogged filter restricts airflow, making your air conditioning and heating systems work harder to maintain the desired temperature. This can result in weak airflow from the vents, especially on lower fan settings. You might find that it takes longer for your car to cool down or heat up.
Unpleasant Odors: As the filter collects dirt and moisture, it can become a breeding ground for mold and bacteria. This can lead to unpleasant, musty odors circulating throughout the cabin, particularly noticeable when you first turn on the AC or heater.
Allergic Reactions and Respiratory Issues: A dirty filter allows allergens like pollen and dust mites to enter the cabin, potentially triggering allergic reactions, asthma symptoms, and other respiratory problems, especially for passengers with sensitivities.
Strain on HVAC System: A restricted airflow forces the blower motor to work harder, potentially leading to premature wear and tear on the motor itself and other components of the HVAC system. This could result in costly repairs down the line.
Foggy Windows: In humid conditions, a clogged filter can contribute to fogging of the windows, making it difficult to see clearly and increasing the risk of accidents.

Essentially, a neglected cabin air filter doesn't just make your ride less comfortable; it can also impact your health and potentially damage your vehicle's HVAC system.

Is it really the cabin air filter? How to Diagnose the Issue.

While a dirty cabin air filter is the most likely culprit for the symptoms mentioned above, it's important to rule out other potential causes. Here are a few things to check:

Check the Blower Motor: Turn on the fan to the highest setting. Can you hear the blower motor running? If not, the motor itself might be faulty.
Inspect the Air Vents: Make sure the air vents are not blocked by debris or obstructions.
Consider Refrigerant Levels: If the air conditioning is blowing warm air, even after replacing the cabin air filter, the refrigerant level might be low, requiring a recharge. This is more likely if the AC performance has been gradually declining over time.

If you've ruled out these other possibilities, then it's highly likely that the cabin air filter is the problem.

The Solution: Replacing the Cabin Air Filter

Replacing the cabin air filter on a 2015 Nissan Murano is generally a simple DIY task that most owners can handle with basic tools and a little patience. Here's a step-by-step guide:

Tools and Materials Needed:

New Cabin Air Filter (Make sure it's the correct one for your 2015 Murano. Check your owner's manual or a parts store website for the correct part number.)
Phillips head screwdriver (possibly, some models use clips only)
Flashlight (optional, but helpful)
Gloves (optional, to keep your hands clean)

Step-by-Step Instructions:

Locate the Cabin Air Filter Housing: On the 2015 Nissan Murano, the cabin air filter is typically located behind the glove compartment.
Empty the Glove Compartment: Remove all items from the glove compartment to make it easier to access the filter housing.
Detach the Glove Compartment: There are two main ways the glove compartment is usually detached:
- Squeeze the Sides: In many cases, you can detach the glove compartment by squeezing the sides inward. You'll feel or hear the retaining tabs release, allowing the glove compartment to swing down further. Sometimes, there's a damper on the right side that needs to be detached by gently pushing it inward and unhooking it.
- Release the Dampers and Hinges: Some Murano models have a damper on the right side of the glove compartment. Gently detach it by pressing on the end of the damper and sliding it off its mount. Then, look for hinges on the bottom of the glove compartment. These may have clips or tabs that need to be released to allow the glove compartment to swing down completely. You might need a small screwdriver to gently pry them open.
Locate the Filter Housing Cover: Once the glove compartment is fully lowered, you'll see a rectangular plastic cover behind it. This is the cabin air filter housing cover.
Remove the Cover: The cover is usually held in place by clips or screws.
- Clips: If it has clips, gently press or pry them open to release the cover.
- Screws: If it has screws, use a Phillips head screwdriver to remove them.
Remove the Old Filter: Carefully slide the old cabin air filter out of the housing. Note the direction of airflow (usually indicated by an arrow on the filter frame). This is important for installing the new filter correctly. Be prepared for some dust and debris to fall out as you remove the filter.
Clean the Housing (Optional): Use a vacuum cleaner or a brush to remove any remaining dust or debris from inside the filter housing.
Install the New Filter: Slide the new cabin air filter into the housing, making sure the airflow arrow is pointing in the same direction as the old filter.
Reinstall the Cover: Replace the filter housing cover and secure it with the clips or screws.
Reattach the Glove Compartment: Reattach the glove compartment by reversing the steps you took to remove it. Make sure the dampers and hinges are properly reconnected.
Test the System: Turn on the ignition and test the air conditioning and heating systems to ensure proper airflow.

Tips for a Smooth Replacement:

Consult Your Owner's Manual: Your owner's manual provides specific instructions and diagrams for your 2015 Murano model.
Take Pictures: Before removing any parts, take pictures of the assembly. This will help you remember how everything goes back together.
Be Gentle: Avoid using excessive force when removing or installing parts. Plastic components can break easily.
Check the Filter Direction: Ensure the airflow arrow on the new filter is pointing in the correct direction.
Wear a Mask: Consider wearing a dust mask to protect yourself from inhaling dust and debris while replacing the filter.

Cost Considerations

The cost of replacing the cabin air filter on your 2015 Nissan Murano depends on whether you do it yourself or have a professional do it. Here's a breakdown:

DIY Replacement: The cost of the cabin air filter itself typically ranges from $15 to $35, depending on the brand and quality. You'll also need to factor in the cost of any tools you don't already own, although as mentioned, this job usually only needs a screwdriver.
Professional Replacement: If you choose to have a mechanic or service center replace the filter, you can expect to pay between $50 and $100 or more. This includes the cost of the filter and the labor charges. The exact price will vary depending on the shop's hourly rate and the complexity of the job.

Given the relatively low cost of the filter and the ease of replacement, doing it yourself is generally the most cost-effective option.

When Should You Replace Your Cabin Air Filter?

Nissan recommends replacing the cabin air filter every 15,000 to 30,000 miles or every 12 to 24 months, whichever comes first. However, this is just a general guideline. If you drive in dusty or polluted areas, or if you notice any of the symptoms mentioned earlier, you may need to replace the filter more frequently. A good rule of thumb is to check the filter at every oil change and replace it as needed.

Regularly replacing your cabin air filter is a simple and inexpensive way to maintain a healthy and comfortable driving environment and protect your vehicle's HVAC system. So, don't neglect this important maintenance item!
