In general, most air filters are recommended to be changed every 90 days or 3 months. This can vary depending on the location of your home, if you have pets, and the age of your system and equipment. A good rule of thumb for pleated air filters (such as those made by FilterBuy) is to replace them every 90 days. As the filter accumulates more dirt, dust, and allergens from the air, its efficiency decreases.
Fiberglass air filters should be changed approximately once every 30 days or as suggested by the manufacturer. Pleated air filters should be replaced approximately every three to six months. However, the frequency of air filter replacement depends on several important factors, such as your home, occupants, and location. Homes with multiple people will need to replace air filters more often than homes with a single occupant.
Long-haired pets shed more hair than short-haired pets, but all of them contribute to the appearance of dandruff in the air. To find the right size filter for your home, check the sides of the existing air filter for dimensions, then go online or to a local home improvement store to find an air filter that matches the dimensions listed. Your boiler's user manual will specify the best MERV rating for your boiler 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. Changing air filters is a quick and painless process that can be done in less than an hour. By filtering contaminants, the oven filter improves the quality of the home's air and makes breathing easier.
If you change your air filter and these problems persist, we recommend that you contact a professional HVAC technician to help you fix the problem. There is no strict guideline for when an oven filter should be changed, but if it shows only a subtle layer of dirt below which the filter material is still visible, it means that it is working properly. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home. In conclusion, it is important to consider several factors when deciding how often an oven filter should be changed. Most manufacturers and HVAC companies suggest changing the air filter every 90 days or 3 months. However, this can vary depending on your home's location, if you have pets, and the age of your system and equipment.
