Air filters are an essential part of any HVAC system, as they help to keep the air clean and free of pollutants. But what exactly are air filters, and how do you choose the right one for your home or business? In this article, we'll discuss the different types of air filters, their nominal and actual sizes, and how to measure for the right size. We'll also cover the importance of air filters in car performance, how to change cabin and engine air filters, and the benefits of using custom-sized air filters. Finally, we'll discuss the importance of air filter ratings such as MERV and HEPA, and how they can help improve indoor air quality.
What Are Air Filters?Air filters are devices that are used to remove dust, dirt, pollen, and other airborne particles from the air.
They are typically made from paper or fibreglass material and come in a variety of sizes. Air filters are used in a variety of applications, including HVAC systems, car maintenance, window ACs, and air purifiers. The type of filter you need will depend on the application.
Nominal Size vs. Actual SizeWhen shopping for an air filter, it's important to understand the difference between nominal size and actual size.
Nominal size is the size that is printed on the filter package or label. This is usually a rounded number that is close to the actual size of the filter. Actual size is the exact size of the filter, which can be measured with a measuring tape.
Measuring for Air Filter SizeTo ensure you get the right size filter for your HVAC unit or car engine compartment, it's important to measure for the correct size. To do this, you'll need a measuring tape and a few minutes of your time.
Measure the length, width, and depth of your HVAC unit or engine compartment to get an accurate measurement. Once you have these measurements, you can use them to find an air filter that fits your needs.
Importance of Air Filters in Car PerformanceAir filters play an important role in car performance. They help to keep dirt and debris out of the engine compartment, which can lead to better fuel efficiency and improved performance. It's important to change your car's air filters regularly to ensure optimal performance.
If you're not sure how to change your car's air filters, consult an automotive technician for assistance.
Types of Air FiltersThere are several types of air filters available on the market today. The most common types are cabin air filters and engine air filters. Cabin air filters are used in cars to help keep the interior clean by filtering out dust and other airborne particles. Engine air filters are used in cars to help keep dirt and debris out of the engine compartment.
Benefits of Custom-Sized Air FiltersCustom-sized air filters can be beneficial for those who need a specific size that isn't available in standard sizes. Companies like Colorfil Filters offer custom-sized air filters that can be tailored to fit any HVAC unit or car engine compartment. Custom-sized air filters can also help improve indoor air quality by trapping more pollutants than standard-sized filters.
Air Filter Ratings: MERV & HEPAWhen shopping for an air filter, it's important to consider its rating.
The most common ratings are MERV (Minimum Efficiency Reporting Value) and HEPA (High Efficiency Particulate Air). MERV ratings range from 1-16 and indicate how effective a filter is at trapping pollutants such as dust mites, pollen, mold spores, pet dander, smoke particles, volatile organic compounds (VOCs), and allergens. HEPA filters are even more effective at trapping pollutants than MERV rated filters. They are rated at 99.97% efficiency at trapping particles as small as 0.3 microns in size.
HEPA filters are often used in hospitals and other medical facilities where cleanliness is essential.
ConclusionAir filters play an important role in keeping our homes and businesses clean by trapping dust, dirt, pollen, VOCs, allergens, and other airborne particles from entering our living spaces. It's important to choose the right type of filter for your needs based on its nominal size vs actual size measurements as well as its rating such as MERV or HEPA. Custom-sized air filters can also be beneficial if you need a specific size that isn't available in standard sizes.
By understanding how air filters work and choosing the right one for your needs, you can ensure that your home or business has clean air.
