If you just got a heating installed or if you just moved into a new house and have never had to deal with heaters, then you may not know much about filters. Filters are responsible for filtering out impurities from the inside and outside so that they don't actually enter into your HVAC system. The result? Cleaner air for you and your family. Before you go out and pic just any type of filter and try to put it into your system, this article will take a closer look at a few things for you to know. Are you ready to learn some more? If so, then read on.

Look for the Right Size

When you go to your local home improvement store and start to look for filters, you will notice that they come in all sorts of different sizes and thicknesses. So, how can you tell which one is the perfect size for your system? Open up your stem and see. Usually, your furnace's air filter will be in the big square heating unit (or your furnace). Typically, there will be a hinge to pull on and then your filter will be inside of there. If you can't find it on your special unit, just search on line and it should pop up. Once you have found your filter, there should be a sticker on the inside of your furnace that says the size of filter to get. From there, you can go buy it.

Consider Thicker Filters

The thicker the filter is, the less often you will have to switch it out. If you are the type of person who forgets to switch out their air filter or if you live near a lot of dirt and your filter gets dirty quickly, then getting a thicker filter will be best for you. Traditional filters tend to last about three months on average whereas thicker filters can last up to six months on average.

Insert It Properly

Once you have purchased the right size and thickness of a filter, now you have to make sure that you insert it properly. There should be a sign on your furnace that has arrows that points to which side is up and which side is down. Additionally, your filters should also have arrows that will do the same thing.

Now that you know all about furnace filters, you can either install one yourself or contact your furnace service professional today and have them assist you.
