Just put it in and the flow is good, but it only measured out at 3 1/2 inches Deep and my filters measure out 4 inches. Its a little loose, but Im sure it will work just fine.
I purchased what I thought was a 16x25x4 filter. What I received was marked with those dimensions but its actual size was smaller and didnt fit snuggly. Please sell your filters by their correct and actual dimensions.
Shipping speed and cost are on point. Size is 100% not for this specific filter. These are a full 1/2" off from their "advertised dimension". It's on me for not noticing it on the product page. I assumed they were standard sized maybe 1/16" off. These leave a huge gap in our air handler that I had to create a buffer for. I'll keep buying other custom sized filters here but look elsewhere if you require an exact to dimension fit.
I've been using filterbuy for 3 plus years and they're always great for an excellent price. It's also great to support companies who make their products in the USA.
