I was afraid it might be sized a little too large for the intake area but actually it is perfect. No more rattles or bumps when the air goes on and off. Filter appears very thick compared to box store items.
This is my second time ordering a 6 pack of these filters which lasts me roughly a year. They are of same quality at a fraction of the price compared to the big box store.
the first filter I used in my main intake started to whistle loudly and hum after a few days. Replaced it with another new filter from the package and the issue went away - near-silence
