Selecting the ideal air filter for your HVAC system can be a challenging task. But with a few key points in mind, it doesn't have to be. The size and type you require depends on the manufacturer of your equipment. Examining the measurements of your current air filter is the simplest way to determine the size you'll need.
The Minimum Efficiency Reporting Value (MERV) is a metric used to evaluate the capability of a filter to remove particulate matter from the air. MERV ratings measure the efficiency and effectiveness of air filters in capturing particulate matter in the air. Most residential air conditioning systems are not designed to adapt to the highly restricted airflow of HEPA filters. When selecting an air filter, it's important to consider your home's environment.
A heavily carpeted urban home with three cats and two dogs will have worse indoor air quality than one without pets or carpets. Therefore, you may need a higher MERV rating than someone with a pet-free home. Air filters can be easily ordered with the number printed on an existing product, or you can measure the actual size of the opening where the filter is installed to determine the nominal filter size you need. We suggest removing the existing filter and measuring the filter to confirm the actual dimensions.
In a home with normal air quality, fiberglass filters should not be replaced more than once a month and pleated filters every 30 to 90 days. If you're going to purchase a replacement filter at a big box store, don't be deceived by the arbitrary ratings that some companies give to their filters. Just like when you measure the filter itself, the air filter slot will be the same size as the actual filter, not the size of the replacement you need. When it comes to selecting an air filter, it's important to consider your home's environment and MERV rating needs. To ensure that you get an accurate measurement, take out your existing filter and measure it before ordering a replacement.
Additionally, don't be fooled by arbitrary ratings given by some companies when buying from big box stores. With these tips in mind, you can easily find an air filter that meets your needs.
