Choosing an HVAC air filter may seem simple, but several common mistakes can lead to an incorrect replacement. Understanding these mistakes can make the buying process more organized.
Choosing by Size Alone
Physical dimensions are important, but size alone does not provide all the information needed. The rating, construction, and system compatibility should also be reviewed.
Ignoring Filter Thickness
A filter with the correct length and width may still be too thick or too thin for the designated compartment.
Always compare the complete dimensions.
Selecting a Rating Without Checking the System
Choosing a filter solely because it has a particular rating can overlook the requirements of the HVAC equipment.
Review available system guidance before selecting a different filter rating.
Forgetting Pack Quantity
A single filter and a multi-pack may have different quantities and prices. Check the package contents before ordering.
Conclusion
Common HVAC filter buying mistakes include checking only the size, ignoring thickness, choosing a rating without reviewing compatibility, and overlooking the pack quantity. A complete specification check can help avoid these issues.
