When it comes to air filters, the MERV rating is an essential factor to consider. MERV stands for Minimum Efficiency Reporting Value, and it is a rating system developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE). This rating indicates the size of particles that the air filter is designed to capture. The higher the number, the better the filter will be at trapping small particles.
If you don't have pets or suffer from severe allergies, a MERV rating of 5 to 8 may be a suitable option. However, if you have pets or suffer from a respiratory condition, you can consider setting a higher minimum efficiency value, from 9 to 12. Generally speaking, our recommended MERV rating for oven filters ranges from 6 to 8, in order to achieve a perfect balance between maximum oven efficiency and home comfort. Activities such as home renovation, leaving outdoor doors open, and children playing in the house can accelerate the buildup of dust and particles in the air filter. Some air filters, especially those with higher MERV ratings, can impede air flow due to improved air filtration.
One thing to keep in mind is that not all HVAC units can accommodate air filters with higher MERV ratings. Every time you use the air conditioner or boiler, the air filter will become dirty as dust and particles flow through the system and accumulate in the filter. To help you determine the MERV classification needed for a variety of configurations, here is a table that can help you:
- If you don't have pets or suffer from serious allergies, a MERV rating of 5 to 8 may be a good option.
- If you have pets or suffer from a respiratory condition, you can consider setting a higher minimum efficiency value, from 9 to 12.
- Our recommended MERV rating for oven filters ranges from 6 to 8.
- To further improve indoor air quality, household air purifiers that employ HEPA (high-efficiency particulate air) filters can theoretically remove 99.97 percent of mold, pollen, bacteria, and other particles down to 0.3 microns.
- A filter with a MERV rating of around 10 to 12 is enough to remove most allergy-causing particles from your home air.
- Before you buy a new oven filter, be sure to check if your air conditioning system has a MERV rating limit.
By following these guidelines and taking into account your specific needs and environment, you can make sure that your home is safe and comfortable.
