Filterbuy 12x30x1 Air Filter MERV 8 Dust Defense (2-Pack), Pleated HVAC AC Furnace Air Filters Replacement (Actual Size: 11.88 x 29.88 x 0.75 Inches)

The size that I purchased is the correct size for my application. This filter is just slightly smaller (~.25-.5") in its external dimensions than similar filters purchased in this size. The intake is mounted on the ceiling, which means that the filter has to be wedged into place with shims so that it doesn't get vacuumed up and then dropped back down against the grate each time the HVAC comes on.The actual filter itself is good -- comparable to similar products. Build quality is fine. The issue with it is that the sizing means that it requires some rigging in order to not hear a little "clunk" each time the heat/AC fan turns off.

I change out my filters regularly. These are an economical product that filter well. This is an odd size filter but they are available here!

Well, it does exactly what it's supposed to do... it fit perfectly with maybe a 1/4 in gap. I have noticed a significant difference in filtration over cheap filter so I'd say for the price it's totally worth it.

These filters work well and I will purchase again. Also, the price is right.

Good filters

Does the job.

We are unable to find this size at our local hardware stores or even big box stores such as Home Depot and Lowe's. They arrive super fast and good quality.

Just what I needed and couldn’t find the right size in store.

Was Good. Was hard to find the size I wanted anywhere else.
