The carbon air filter may cost more than the particulate filter that does not have carbon, but if you drive frequently in slow traffic or encounter strong odors while driving, the investment in a carbon cabin air filter could be worthwhile. You'll pay more for a washable air filter because it should last for years, instead of months. However, there are multiple problems associated with this type of filter, such as lower MERV ratings, frequent maintenance requirements, and the potential to attract mold to your air unit. Even the best cabin air filter will wear out over time.
Most filters are made of paper and are designed to be changed once they become clogged. Beware of any filter that says it is a “for life” replacement. Buy a quality filter from a trusted brand that also fits your vehicle. If someone tries to convince you to reach the moon in the process, they should set off alarms and send you running for the hills.
The cheapest filters are made of spun fiberglass, which does very little to filter the air compared to materials such as paper, cotton or polyester. In addition, pleated filters do not have to be changed as often as just one every 3 months compared to the once-a-month frequency of non-pleated filters. However, if the cabin air filter is under the dashboard or under the hood, it may not be as accessible. This is especially true in homes with older HVAC units, which weren't built to accommodate thicker air filters.
The reason you should replace the cabin air filter by yourself is because the procedure is very easy and quick. Before air can enter the interior of the car, it passes through this filter and traps any contaminants inside the air to prevent them from infiltrating the air you breathe. Placing more folds (sometimes called folds) on air filters increases their surface area, and more surface area means more space to trap particles in the air. When comparing the cost of a pleated filter with a non-pleated filter, you have to triple the price per filter of the non-pleated filter to get an accurate comparison. When shopping for air filters online, look for places that allow you to customize your quantity to get exactly what you need.
That's a myth: The extra surface allows more air to pass through, so the HVAC central unit doesn't have to work as hard to push air through it. If you've ever wondered what the difference is between pleated and non-pleated cabin air filters, here's your answer: Pleated filters have more folds than their non-pleated counterparts, which increases their surface area and allows them to trap more particles in the air. In addition, pleated filters do not have to be changed as often as just one every 3 months compared to the once-a-month frequency of non-pleated filters. When it comes time to replace your cabin air filter, make sure you buy a quality product from a trusted brand that fits your vehicle.
