Product review (2 stars): Not equivalent to original equipment filter
Lacking an alternative, it is better than nothing, but:  Filter is described as 8" x 31" x 1" (equal to original equipment). Actual size received is 8" x 31" x 3/4". That 1/4" difference is a significant loss in thickness. The product had 'Prime' status,  was ordered on Jan 3, 2018, given estimated delivery date of Jan 9 - Jan 12, and actually delivered on Jan 18, 2018. 'Prime' used to mean 2 day delivery; now it seems to not have any meaning.
