In most homes, you'll find the air cleaner housing located right next to the air handler for your heating or cooling system. This is a large metal box with a fan motor and a fan inside. Most air handlers are installed in the basement, attic, or utility closet. Some larger homes have more than one HVAC system, and each will have at least one filter.
First take a look at the filters inside or near the HVAC unit itself. Most likely, these filters will be located next to the oven or air conditioner of the air conditioner. The HVAC unit can often be found in an attic, basement, or in the back of a closet (somewhere far away). Once you've found the unit, look for a hinged or removable cover approximately one inch wide.
It can be oriented horizontally or vertically, and you should find a filter already in place. Chances are that your heating and cooling system is where the air filter is located. If you're not sure where your air handler is located, check the attic, basement, mezzanines, or garage. If you live in a smaller space (such as an apartment), your unit is likely in a closet.
Usually, the air cleaner is close to your home thermostat, in a return duct. Or, it's most likely right next to the air handler for your air conditioning system. The media filter has a high MERV rating that competes with the filtration system of an expensive high-MERV filter. It's common knowledge that you need to replace air filters regularly, and if you don't, damage and costly repairs often result in your HVAC system.
Air filters should be changed every 30 days or once a year to ensure that indoor air quality remains high and to protect your HVAC system. Most homes, especially large ones with multiple HVAC systems, have more than one air filter installed. If you recently moved or bought a new home, you might be wondering where your HVAC air filters are located. It is also the filter recommended by the Department of Health, as it filters even the smallest particles, such as bacteria.
As if clean air in your home weren't enough, air filters also offer the added benefit of extending the life of your HVAC system. Because HVAC units are often installed in a more difficult access area, filters are sometimes placed here for better accessibility. If you're not sure which type of air cleaner is best for your system, talk to an HVAC professional. Either way, make a habit of inspecting your filter and your entire HVAC system for optimal and consistent results.
Since HVAC units are generally hidden in smaller, less convenient spaces, some homes are configured for air filters on the return grilles. Now that you've finally found your oven filter, you can learn how to change the air filter and start changing the filter as often as you should. Changing air filters regularly is a crucial part of regular home maintenance, but for new homeowners, maintaining air filters can be one of those small jobs that get undone because they don't know much about them.
