When it comes to selecting the ideal air filter for your home, size, MERV rating, and material are the three main elements to take into account. To guarantee that the replacement filter is the right size, check the numbers printed on the existing filter. If there are no measurements, you can measure the existing filter or the grid to find the dimensions of height, width and depth. The next step is to decide on the desired level of particulate capture efficiency.
Pleated HVAC filters can improve your home's indoor air quality by trapping dust, pollen, and other small particles. To be considered a true HEPA filter, an air filter must be able to capture 99.97 percent of particles that are 0.3 micrometers or larger in size. An HVAC professional would install a small cabinet next to the boiler or air controller (on the air intake side) to hold the thicker filter. You should anticipate replacing the filter every three to 12 months of use, depending on its size. You may need to replace it more often if you have some very furry pets, or if you live in an area with a lot of air pollution.
Equipping your system with an adequate air filter is especially important in Texas, where hot summers and cold winters mean that air conditioners or ovens are running most of the year. Once you know what type of filter you're looking for, knowing the MERV range you want will help you choose the right air filter. With a MERV 13 rating, you can count on the filter to stop bacteria, smoke, and other microscopic particles. But these are usually filters with a rating of at least MERV 11, which is when filters begin to trap most particles the size of common allergens. When it comes to selecting an air filter for your home, it's important to take into account all three factors: size, MERV rating and material. Knowing your desired level of particulate capture efficiency and MERV range will help you choose the perfect air filter for your home.
It's also important to remember that filters should be replaced every three to 12 months depending on their size and usage.
