Are you looking to buy air filters online? Whether you need a filter for your HVAC system, oven, or air conditioning unit, you can find the right filter for your home with ease. All of our air filters are high quality and made in the USA, and we offer fast shipping and free returns on all of our discounted oven filters. Choosing the right air filter comes down to understanding your needs and the right filter to get the job done. The best way to measure the size of your air filter is to take out the measuring tape and measure it directly.
Once you have a replacement filter of the right size, it's time to place the new filter in the intake vent. Air filters can be changed from behind the intake grilles (often called air filters or AC filters) or in the oven box of the central air unit (often referred to as “oven filters”). We offer standard, hard-to-find Aerostar air conditioning filters customized for your home or business. Almost all AC filters are based on the nominal size, which is the actual size rounded to the nearest centimeter.
When replacing the air cleaner, most people will find the nominal size or dimensions on the edge of the current air cleaner. Most air filters have a MERV rating between 1 and 20, with MERV 1 filters only capable of removing larger debris and MERV 20 capable of filtering microscopic particles such as viruses and bacteria from the air. Air cleaners perform three fundamental functions in your central air system that contribute to the health and comfort of residents and customers. MERV stands for Minimum Value of Efficiency Reports and is an industry standard for rating the effectiveness of a filter.
