When it comes to car maintenance, people tend to make a checklist of what takes highest priority. Things like changing the oil, getting the brakes checked, and topping up the washer fluid are all commonly found on maintenance checklists. However, there’s one thing that people frequently overlook, and that’s the cabin air filter. It’s easy to forget about the cabin air filter because the two other filters (oil and engine air) tend to be the ones that people think about most often. The cabin air filter is just as important, and that’s why we at Westbury Toyota are going to show you a quick list of the reasons why you should be sure to change your Toyota’s cabin air filter on a regular basis.

What Does the Cabin Air Filter Do?

It’s kind of surprising that more people don’t know about the importance of the cabin air filter considering what it does. The cabin air filter ensures that there is a steady stream of clean air flowing throughout the cabin. What’s more, this filter keeps out things like pollen, allergens, dirt, bacteria, dust, and exhaust gas from entering the cabin. This is very important for everyone, but especially people who suffer from allergies in the warmer seasons. The cabin air filter also functions as a barrier, explains the experts of Champion Parts, as it stops debris like leaves and insects from clogging up your vehicle’s ventilation system.

If you have an older car, you may not have a cabin air filter as it is something that was added to most vehicles manufactured after 2000. In the cars that do have one, you’ll typically find it located either behind the glovebox or under the hood or dashboard.

How Can You Tell the Filter Needs to be Replaced?

The general rule of thumb is that the cabin air filter should be replaced every 15,000 to 25,000 miles. However, given that most people tend to forget it exists, it often goes without being replaced for a lot longer than that. Telltale signs that it needs to be replaced include:

  • Decrease in air conditioning and heating performance
  • Whistling sound coming from the cabin air intake
  • Unusual musty odor in the cabin
  • Decrease in overall air circulation throughout the cabin

If you’re experiencing any or all of these in your vehicle, it’s very probable that the filter is in need of replacement. Changing the filter yourself can be a bit of a tough job considering that the location may be difficult to get to, but if you enjoy the challenge there are plenty of tutorial videos online that will guide you through the process. If you’re not all that mechanically inclined, a professional here at Westbury Toyota can swap your old filter for a new one the next time you book your car in.

Why Should I Replace the Filter?

We’ve already touched on one reason why the cabin air filter should be routinely replaced: Clean air. You won’t have to worry about allergens when you air filter is in good shape and it just makes the air in the cabin better to breathe, overall. Another significant reason the filter should be regularly maintained is that a dirty filter can actually lead to expensive repairs, says the writers of Angie’s List. A dirty and clogged filter can lead to the air conditioning working overtime, which in turn can lead to issues with the motor.

Keep Your Cabin Air Clean and Healthy

Anyone with allergies knows that spring on Long Island can be a trying time of year. Fortunately, if you change your filter when it needs replacing, you won’t have to worry about breathing in pollen, allergens, dust, and dirt while driving your car. You’ll also be keeping your air conditioning in good working order, eliminating the need for repairs down the line.
