Air filters should be the exact size specified for your HVAC. This is to ensure proper airflow and filtration efficiency. An incorrect size leads to gaps that allow unfiltered air to bypass the filter.
MERV 11 filters are suitable for residential use. Especially for households with allergies or respiratory issues. However, they may restrict airflow in some units, so it's important to check compatibility with your HVAC.
While cheaper air filters may save money upfront, they often provide less effective filtration and may need to be replaced more frequently. Investing in higher quality filters improves air quality and efficiency in the long run.
Using an air filter that is too big can cause installation issues and may prevent the filter from sealing properly leading to air bypass. It's best to use the correct size for optimal performance.
Using the wrong size air filter can result in reduced airflow, decreased efficiency and potential damage to your HVAC. It can also allow dust and allergens to circulate in your home, compromising air quality.
