If you're using a higher-efficiency filter, such as a MERV 11 or higher, you may need to change it more often. This is because they can cause air restriction due to their larger surface area. As with MERV 13 filters, it is often recommended to change MERV 10 filters every 30 or 90 days. One of the most popular types of filters is the MERV 8 filter.
These pleated filters trap up to 70% of particles between 3.0 and 10 microns in size and up to 20% of particles between 1.0 and 3.0 microns. Unfortunately, they are not effective enough for smaller particles of 0.3 to 1.0 microns. If your air conditioning system is old or not very powerful, this is a great option because it allows the oven or air conditioning unit to operate at a higher capacity and, at the same time, trap many of the irritants that flow through the filter. A number of factors must be considered when deciding how often an oven filter should be changed, and many filter manufacturers recommend how often the product should be replaced.
Located at the upper end of residential air conditioning filters, the MERV 13 filter traps up to 90 percent of particles with a size of 3.0 to 10.0 microns and up to 50 percent of particles of 0.3 to 1.0 microns. In some cases, low-quality fiberglass air filters will need to be replaced every month, while higher-quality pleated air filters can be replaced every three months, depending on usage and other factors. Replacing your air filter can save you money and ensure that your air conditioning system is operating at optimal levels. It is also a good option for those with less powerful air conditioning systems, since a MERV 10 filter will make it less difficult for air flow to flow, which will generate less stress on the heating and cooling system and, at the same time, will trap certain impurities in the air.
So when should you replace your air filters? Ideally, MERV 13 filters should be changed every 30 to 90 days, depending on usage and other factors. As for MERV 8 filters, it is often recommended to replace them every 90 days. Before analyzing the signs that it's time to change your air filter, it's first important to understand the most common types of filters on the market. The furnace owner's 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.
Filters are assigned a minimum efficiency value (MERV), which ranges from 1 to 16, although scores of 6 to 12 are the best for residential ovens. Because filters with higher MERV ratings are denser, the oven must work harder to get air through them, and not all ovens have enough power to do so. Marking the calendar every 90 days or trying to remember the last time you changed the filter can be complicated, so many oven manufacturers recommend changing them at the start of each new season. To make sure your home's air quality remains healthy and your HVAC system runs efficiently, it's important that you replace your MERV 8, MERV 10, and MERV 13 filters regularly according to manufacturer recommendations.
