Your air filter is one of the most important components of your HVAC system. As air flows through your system, the filter collects dust, dander, and other contaminants. An air filter’s main function is to keep those nasty particles from flowing throughout your HVAC system. Without an air filter, particulate matter can accumulate on the most important parts of your system, potentially leading to costly repairs. Plus, your indoor air quality would be compromised.
When should I change my air filter?
On average, your filter should be changed every month. The best way to determine whether your filter needs to be replaced is to take it out and hold it up to a light. Can you see any light passing through the filter? If you see little to no light coming through the filter, it’s definitely time to replace it. A few things to consider when determining how often to change your filter are the type of furnace you have, the number of animals and people in your home, and the manufacturer’s recommendations. Depending on the kind of HVAC system you have, there may be different filter options to choose from.
Let’s go over a few tips to help you decide which type of filter to install!
Choosing an Air Filter: MERV Ratings
While glancing down the aisle at the store for air filters, one thing you should look for is the MERV rating. The MERV rating can range from 1 to 20. The higher the rating, the more particulates will be filtered. The average rating for most households is between 5 and 13. But be careful not to choose a filter with a MERV rating that is too high, as this can restrict airflow, cause your system to overwork itself, and reduce efficiency.
Different Types Of Air Filters
We know it’s easy to get overwhelmed when deciding on the right filter for your home—there are a ton of options! But understanding the differences among these options can help you decide what is best for you, your family, and your HVAC system.
A few commonly known types of filters are HEPA, pleated, and electrostatic filters. Our technicians recommend a simple pleated filter, which is not only affordable but also the least restrictive option for airflow. Since it is a more basic filter, it is highly recommended that it be replaced monthly.
Although some more expensive filters can reduce efficiency and restrict airflow, you may still see benefits from choosing one. Some more heavy-duty filters can help with allergies and asthma symptoms. The main concern would be that it isn’t overly restrictive and doesn’t affect your system’s performance. Our technicians can help you decide which filter is right for you and your HVAC system.
