Very disappointing since its not true to size.

I loves me my Filtrete filters, but they now cost more than an elephant. Nope.

Excellent filtration.

I am a very cheap person when it comes to filters. And usually I find my self dusting constantly. I couldnt figure out why my house was always so dusty. Well, I finally decided to change the filter, and these are the ones I picked. Holy COW...I could tell a HUGE difference. It was like night and day. WILL NOT be going back to the cheap brand. Sometimes its ok to cut corners, but NOT with your filter.

Great products.
