About Filtrete 18x30x1 AC Furnace Air Filter
96% praised for improving indoor air quality
I recommend these filters as excellent, but carefully check the product description for actual size to ensure clearance in your intake.
90% liked its compatibility, but 10% had issues with compatibility
I recommend checking the product description for the actual size of the filter to ensure it fits in your intake.
The filter size mentioned in the product description was incorrect as it exceeded 24 inches.
92% found it easy to install and replace, but 8% had difficulties
The filter was not easy to install as it is nearly 1/2 cm too big for my ceiling intake.
91% liked the long-lasting filter, while 9% thought it needed frequent replacements
The filter has improved my daughter's allergies and reduces dust buildup on furniture. The airflow remains unaffected as the filters age.
I am hoping that the filters are still sturdy and will work, as the outside box is soaked.
I regret not trying the filters when I bought them months ago because they are too big and I can't afford to replace them.
88% appreciated the quieter operation
I ordered the filters before from another retailer and they fit my ceiling intake perfectly.
