Everything You Need to Know About Air Filter Sizes

Air filters are an essential part of any car engine, as they help to keep the engine clean and running smoothly. But with so many different types and sizes of air filters available, it can be difficult to know which one is right for your car. In this article, we'll discuss the different types of air filters, how to measure air filters, and how to choose the right size for your car. When it comes to air filters, there are two main types: nominal size and custom-sized air filters.

Nominal size air filters are the most common type and are available in a variety of sizes. These air filters are designed to fit into a standard-sized air cleaner slot in your car's engine. Engine Masters, K&N Filters, and AFE Pro 10R are some of the most popular brands of nominal size air filters.Custom-sized air filters are designed to fit into a specific size slot in your car's engine. These air filters are usually more expensive than nominal size air filters, but they provide better engine protection and filtration.

If you're looking for a custom-sized air filter, you'll need to measure the size of your car's air cleaner slot before you buy one.

How to Measure Air Filters

Measuring air filters is a simple process that requires only a few basic tools. Here's what you'll need:

• A ruler or measuring tape
• A pen or marker
• A piece of paper

Step 1: Measure the length and width of your car's air cleaner slot using the ruler or measuring tape. Mark the measurements on the piece of paper with the pen or marker.Step 2: Measure the depth of the slot using the ruler or measuring tape. Mark this measurement on the piece of paper as well.Step 3: Add all three measurements together to get the total size of your car's air cleaner slot.

This is the size of air filter you'll need to buy.

Types of Air Filters

There are several different types of air filters available on the market today. The most common types are solid cellulose, pleated paper, and foam trap filters. Solid cellulose filters are made from a combination of cotton fibers and synthetic materials. They provide good filtration but have a low dust holding capacity.

Pleated paper filters are made from layers of paper that trap dirt and debris. They have a higher dust holding capacity than solid cellulose filters but can be more expensive.Foam trap filters are made from foam that traps dirt and debris. They have a high dust holding capacity but can be more expensive than other types of air filters. Merv rating is another important factor when choosing an air filter.

Merv stands for Minimum Efficiency Reporting Value and is used to measure how effective an air filter is at trapping particles.
