BNX TruFilter 20x23x1 Air Filter MERV 13 (4-Pack) - MADE IN USA - Electrostatic Pleated Air Conditioner HVAC AC Furnace Filters for Allergies, Pollen, Mold, Bacteria, Smoke, Allergen, MPR 1900 FPR 10

I appreciate that the delivery cardboard box was made to size for these BNX filters so that they didn't move about in the shipping box during the shipping process. I've had enough of poorly packaged shipments arriving with damaged products from other companies. I appreciate that the shrink wrap around the filters had some excess plastic in the corners so that the plastic wrap was easy to pull open without needing to use scissors that could accidently damage the filters. I appreciate the large directional air flow arrows on the cardboard framing of the filters. I appreciate seeing the made in USA designation. It fosters a sense of reliability. I appreciate that recycled cardboard is used in the production of these filters for sustainability. I appreciate that there are 3 steps clearly listed on the product label inside the shrink wrap. I appreciate that the QR code printed on the filters bring you to a linktree site with a lot of useful information and social media links. I appreciate that there is a specified place to write in the installation date of the filter on the cardboard framing of the filter. Regarding functionality, I am pleased. I can see by the color of the recently installed filter that it is picking up dust, dirt, particles and debris in the air already. The filter fits my HVAC slot well and slid in easily. I had a horrible experience with another brand of filter that when I was pulling it out from the HVAC slot, it folded and fell into the unit. I had to call for after hours service because I couldn't get it out and feared leaving it overnight could cause a furnace fire. These filters feel sturdy enough that I shouldn't have to worry about a thin and poorly structured framing. Having watched the "how to replace your filter" youtube video by the manufacturer, I learned I should have turned the thermostat off before removing that filter. Now I know, and that's good to know! Makes perfect sense. I have had a 5/5 star experience with this company, brand, and the product too. In summary, I highly recommend this product!
