One of the most important components of HVAC maintenance and HVAC service in Dacula, GA, is regularly checking and changing your filter. This is important because a clean filter makes it easier for air to pass through the system, which places less wear and tear on the system since it doesn’t have to work as hard. In addition to regularly changing your filter, it’s important to know the different types of filters to ensure you get one that’s fitted appropriately to your home and will filter out contaminants well. Here’s what you need to know about the different types of filters.
When determining the right filter for your needs, the first thing is to figure out exactly what size you need. You can ask your HVAC technician or find information in the system’s owner’s manual or on the filter cabinet somewhere. The filter needs to be the exact size because choosing a filter that doesn’t fit snugly will allow air to escape around the edges of the filter. This means your efficiency will go down and the ability for the filter to work properly is reduced as well. There are numerous filter sizes to choose from, so make sure you know what you need before heading to the store to purchase a new one.
There’s also a difference in the thickness of filters, which varies from one to five inches. Although a thicker filter is generally more effective and energy efficient than a thin filter, you can’t put a thicker filter into an area that wasn’t designed for it. Just as using the wrong overall sized filter will result in a poor fit, using a filter that’s the wrong thickness will reduce efficiency. Many residential systems use a one-inch filter.
The most affordable type of filter is a disposable fiberglass filter. They’re very easy to find and inexpensive. They’re made of fiberglass fibers that are housed in a frame. They’re great for catching dust and other large particles, but not as efficient at actually purifying the air.
Pleated filters are made of cotton, paper, or polyester. These filters have more surface area since the material is folded into pleats. They capture a lot more particles, including dirt, pet dander, and dust mites, while still allowing good airflow. Pleated filters are a good choice for people that are sensitive to allergens because they remove these fine particles.
Pleated filters can be either disposable or washable. Another type of washable filter is an electrostatic filter. These are significantly more expensive than disposable filters, but are permanent and effective at trapping dust and other particles.
A HEPA filter is the best at removing small contaminants, which is important for buildings that need to remove allergens and other very small particles. Almost all of these tiny irritants are removed from the air before circulating through the HVAC system. If air quality is a major concern for you, be sure to choose a HEPA filter.
When considering different filters, pay attention to the MERV rating. This stands for minimum efficiency reporting value and describes the level of filtration a filter can achieve. The ratings go from 1 to 16, and a higher rating means more particles will be trapped. Along with manufacturer recommendations, choose a filter with the highest MERV rating you can afford that will meet your air quality needs.
