Q: What is the difference between an OEM filter and an Aftermarket filter?
A: OEM stands for Original Equipment Manufacturer. Basically, an OEM filter is the brand name filter. Aftermarket filters are generally manufactured by third-party companies and these filters a replacements for the OEM filters. Usually, aftermarket filters are considered a lower-cost alternative to the OEM filters. In most instances the aftermarket filters are built to the same specifications of the OEM filters.
Q: What does MERV stand for?
A: MERV stands for Minimum Efficiencry Reporting Value. Basically, the MERV rating is an indication of how efficient the filtration media is. The higher the MERV rating the smaller the particles the filter captures.
Q: What information do I need to be able to locate my correct filter?
A: It's always best to know your unit's model number and brand. With this information, you should be able to easily locate the filter you need. If you know your filter number, that's even better. If you need a specific sized filter, like a 16x25x1, then you most likely will not need to know your model number as these are common sizes.
Q: What does Actual Size and Nominal Size mean?
A: Certain filters are assigned a nominal size AND an actual size. The nominal size is usually the size that is printed on the side of the filter, or the size that is listed in the product title on a website. The size represents the closest whole number to that particular filter's measurement. The actual size is the actual size of the filter if you were to get a tape measure out and measure the filter. For example, 20x25x5 would be the nominal size, while 19-3/4 x 24-1/2 x 4-3/8 is the actual size. This is why it's important to know the size of your filter and your model number to ensure you order the correct filter.
Q: What does HEPA mean?
A: HEPA stands for High Efficiency Particulate Arrestance. A filter that is labeled a HEPA filter has to meet HEPA qualifications by removing at least 99% of particles that are 2 microns or larger. HEPA filters are generally used in room air purifier units, but can sometimes be used in whole house air cleaners.
