Importance of MERV Ratings

When choosing an HVAC filter, it's crucial to consider the MERV rating, a critical factor determining the filter's efficiency and overall performance. But first, let's tackle some common MERV rating misconceptions. Many folks believe that a higher MERV rating automatically means better air quality. That's not always the case. The higher the MERV rating, the smaller the particles the filter can trap, but it also means your HVAC system needs to work harder to pull air through the filter.

Maintaining your indoor air quality is a balancing act. You want a filter that's efficient enough to capture harmful particles, but not so restrictive that it puts undue strain on your HVAC system. For most residential systems, a MERV rating of 8–13 is optimal. These filters provide a good balance between efficiency and airflow.

Choosing the Correct Filter Size

After you've determined the appropriate MERV rating, it's crucial to select the correct filter size for your HVAC system. This is where filter compatibility comes into play. The wrong size won't fit properly, leading to inefficient operation and potentially damaging your system.

The size of your filter is usually printed on the side of your current filter, in height, width, and thickness. For instance, a common size is 20x25x1. If you can't find the size, or you're installing a new system, you'll have to measure it yourself. Use a tape measure to get the exact dimensions of the slot where the filter goes.

Once you've got your measurements, it's time to purchase your filters. Keep in mind that the stated size on the filter package might not match up exactly with your measurements due to manufacturing standards. Round up to the nearest inch if necessary.

Installation procedures are fairly straightforward. Make sure your HVAC system is off, then simply slide the new filter in, making sure it fits snugly into the slot. The filter's arrows should face toward the furnace. Once it's in place, turn your system back on. Now, you're all set with the right-sized filter.

Types of HVAC Air Filters

You're about to get the lowdown on the different types of HVAC air filters. We'll start with pleated air filters, move on to the basics of fiberglass filters, and wrap up with an explanation of washable air filters. Each has its pros and cons, so let's get started!
