How Often Should You Check and Replace Your 16x25x1 Air Filters?

Most 16x25x1 furnace filters need to be changed every two to three months, but the exact frequency of replacement depends on several factors. At Thomas Galbraith Heating, Cooling and Plumbing of Ohio, we recommend changing filters that are less than 2 inches thick every 30 to 90 days. Three- or 4-inch filters can last 6 to 9 months, and filters up to 6 inches thick can be replaced once a year. Fiberglass air filters should be replaced about once every 30 days, while pleated air filters should be changed approximately every three to six months.

The frequency of air filter replacement also depends on the home, the occupants and their location. If you have one or more pets, it's best to replace a fiberglass air filter about once every 20 days and a pleated air filter about once every 60 days. Larger homes have a larger volume of air circulating, so the filter may need to be changed more often. It's important to inspect your air filter at least once a month to see how dirty it is getting.

You can then compare a clean filter next to a filter that has passed the point of being changed. Keep in mind that a higher rating doesn't necessarily mean that the air filter is the right choice for your home. External factors, such as excess pollen, nearby construction, or a home renovation, can also shorten the lifespan of an air filter. When it comes to maintaining a healthy central air system in their home, homeowners should be aware of regular air conditioning filter changes.

The right air filter replacement frequency for one home may not be the right choice for every home. Another essential home maintenance job that every homeowner should know about is changing the oven air filter. At Thomas Galbraith Heating, Cooling and Plumbing of Ohio, we recommend checking your air filter at least once a month and replacing it when necessary. The exact frequency of replacement depends on several factors such as the type of filter used, the size of your home, and whether you have any pets. Fiberglass filters should be replaced about once every 30 days while pleated filters should be changed approximately every three to six months.

Larger homes may require more frequent changes. It's also important to consider external factors such as excess pollen or nearby construction when determining how often you should replace your air filter.
