MERV 13 filters are among the best options for upgrading your air conditioning system and ensuring better indoor air quality. Generally, they need to be changed every three to six months, depending on the size of your HVAC system and other factors. However, it is recommended to inspect them periodically for any signs of wear and tear, such as dark deposits, pet hair and visible signs of other household irritants. If your home is in an area with high humidity, there are wildfires, smokers, pets or people with chronic allergies and asthma, it is advisable to replace your MERV 13 filters every 30 days.
Fiberglass filters should be changed once every 30 days, while more expensive pleated filters can work well if replaced once every three to six months. If you have pets in your home that shed hair or dander, such as cats or dogs, you may need to replace your MERV 13 filters more often. The frequency of replacement also depends on external factors like the presence of particles in the air. MERV 13 filters are located at the top end of residential air conditioning filters and can trap up to 90 percent of particles with a size of 3.0 to 10 microns and up to 50 percent of particles from 0.3 to 1.0 microns.
Therefore, they are an excellent choice for improving indoor air quality. To ensure optimal performance and maintain good indoor air quality, it is important to replace your MERV 13 filter regularly. The frequency of replacement depends on several factors such as the size of your HVAC system, the presence of pets or smokers in the house, and external conditions like humidity levels and particle concentration in the air. Generally, it is recommended to replace these filters every three to six months. However, if you live in an area with high humidity or have pets that shed hair or dander, you may need to replace them more often. In addition to regular replacement, it is also important to inspect your MERV 13 filter periodically for any signs of wear and tear such as dark deposits, pet hair or other household irritants.
This will help you identify any problems early on and take corrective action before they become serious.
