For Merv 8, 11 and 13 filters, it is recommended to change the filter at least every 3 months for better filtration and healthier air in your home. The MERV rating, or Minimum Efficiency Report Value, measures the effectiveness of the filter in trapping particles in the air. The higher the MERV rating, the more effective the filter will be. We offer MERV 8, 10, 11 and 16 filters for sale in our office and can also order special one-off sizes.
As a general rule of thumb for pleated air filters (such as those manufactured by FilterBuy), it is best to replace the filter every 90 days. However, depending on the location of your home (e.g. dry and dusty climates), if you have pets and the age of your system and equipment, you may need to replace the filter more often. If you have pets in the house, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days.
Vacation homes or vacant homes that don't have much use can usually wait to change filters every 9-12 months. The general consensus is that the more you use your home, the more you need to change the air filter. Most manufacturers will include the MERV rating and filter dimensions on the long side of the filter (see an example here). There are certain household factors that could change the frequency with which the HVAC unit respiratory oven filter needs to be changed. Air filters are usually made of spun fiberglass (the same as attic insulation) or & pleated paper framed with cardboard for added stability and rigidity. A good oven filter can help you improve the air quality in your home, but a dirty air filter will do the opposite.
So, make sure you have the right type of air filter for your air handler, and if you have recently had jobs done around your house or if you own a pet, follow these simple steps to improve your oven's air filter performance. The Minimum Efficiency Report Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter into the air stream. If you are experiencing a freezing winter and the system is in constant use, you should consider replacing the filter more often than every 3 months. The strongest filters are reusable, usually with metal frames, and can be cleaned according to the manufacturer's instructions. When you change the air filter, it allows more air to flow through the system with lower energy consumption, resulting in better circulation, cleaner air and a lower electricity bill. Cats and dogs typically lose the most when winter turns to spring and summer to fall, which are key times to replace the filter. In general, it is recommended to change your Merv 8 filter every 3-4 months, Merv 10-11 filters every 6 months and Merv 16 filters every year.
However, depending on your home environment and other factors such as pets or allergies, you may need to change your filter more often. It is important to keep up with regular maintenance of your HVAC unit respiratory oven filter in order to ensure that it works efficiently and provides clean air in your home.
