A good rule of thumb is to change 1-inch to 2-inch filters every three months, 4-inch filters every six months, and 5-inch filters every 12 months. Certainly, if you can't see the filter material itself, it must be replaced. Keep in mind that this is a general recommendation. There are a few factors that can shorten or extend the time between furnace filter replacement intervals. How often you need to change your oven filter really depends on what's going on in your home.
In most cases, you should change the filter at least every three months, even in summer. If you can't remember to do it, a good rule of thumb is to change the boiler filter every time the seasons change. Generally, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. This may change depending on the location of your home (e.g.
dusty and dry climates), if you have pets, and the age of your system and equipment. If you have pets at home, you should consider changing the filter every 60 days or 2 months, and in the case of households with several pets or people with allergies or respiratory conditions, we recommend that you change the filter every 20 to 45 days. Usually, vacation homes or empty houses that aren't used much can wait to change filters every 9 to 12 months. The general consensus is that the more you use your home, the more you'll need to change your air filter. To keep air quality under control and your home clean, you'll want to replace the filter at least 2 to 3 months apart. Since the functionality, performance and longevity of your oven depend on how often the filter is replaced, Hoffner Heating and Air Conditioning created this guide at a glance.
These air filters act as barriers to prevent contaminants from entering the HVAC system or circulating through the air. The added moisture reduces the filter's ability to contain contaminants and will need to be changed more frequently. The boiler owner's manual will specify the best MERV rating for your furnace and, in general, filters with a MERV rating of 6 to 9 should be changed every 90 days, while those with a MERV rating of 10 to 12 should be changed every 60 days. A number of factors must be considered when deciding how often an oven filter should be changed, and many filter manufacturers recommend how often their product should be replaced. With that said, if you smoke, you should make sure your air filters are clean for you and the rest of your family members.
If outdoor temperatures are extremely cold or hot and the boiler or air conditioner is running non-stop to keep up to date, filters that should have lasted 90 days should be replaced every 30 days to ensure that the HVAC system is working properly. In addition to keeping the HVAC system free of contaminants, oven filters also help clean the indoor air you breathe. In winter, as long as the oven filter is not dirty or clogged, you can use the recommended 90 days before needing a replacement. During a remodeling project, replace the furnace filter every 30 days, or even more frequently, to prevent construction-related dust from circulating around the house. Rather than simply going outside of the standard schedule, here are some special signs and considerations that will let you know when to change an oven filter. If your furniture gets dirty soon after cleaning the house, the oven filter could be clogged and no longer effectively removes dust from the air.
If you have poor outdoor air quality or pets indoors, you'll need to change your air filter more often.
