If you have a newer furnace, it probably has a filter. To check, open the door to the furnace and look for a metal grille. The filter is usually located behind this grille. If you don’t see a grille or can’t find the filter, consult your furnace’s owner’s manual.
Filters help remove these particles from the air, making it easier to breathe and reducing wear on your furnace. Installing a filter is easy. Simply measure the opening of your furnace and purchase a filter that is the same size or slightly smaller. Most filters fit into a metal frame that snaps into place behind the grille.
Does the type of filter matter for your furnace?
Yes, the type of filter does matter for your furnace. The type of filter you use in your furnace can make a big difference in how well it runs. If you have allergies or asthma, you may want to consider using a HEPA filter in your furnace. HEPA filters can remove 99% of allergens and particles from the air, making them ideal for people with respiratory issues.
The most common type of furnace filter is a pleated paper filter, which can be replaced every few months. There are also washable filters, which need to be cleaned every month or two. And finally, there are electronic air cleaners, which should be cleaned every week or two.
Fiberglass filters are the cheapest and most common type, but they don’t always work well. They can become clogged quickly, which can prevent the furnace from working properly.
Pleated filters are more expensive than fiberglass filters, but they last longer and trap more particles. They’re a good option if you have allergies or asthma.
Electronic air cleaners are the most expensive type of filter, but they’re also the most effective at trapping particles. If you have pets or smoke in your home, an electronic air cleaner can help keep the air clean.
Can I just cover the vents?
