Filterbuy 20x25x4 Air Filter MERV 8 Dust Defense (4-Pack), Pleated HVAC AC Furnace Air Filters Replacement (Actual Size: 19.50 x 24.50 x 3.63 Inches)

These filters ate doing the job. The construction is sturdy, without using heavy materials. Airflow remains good through them. Replacing roughly every 30-45 days, trapped dust and particulates are very visible.Being MERV 8, I know not everything is getting trapped. But the ducts and vents remain clean and the airflow for cooling and heating stays good through the filter life.

Filterbuy accidentally shipped me the wrong product. I contacted them and they immediately made the whole situation right with no fuss. I will definitely look to do business with them again if I need a filter product.

Seemed a little less sturdy than my old filter. Easy to install and furnace is working fine.

Be sure to read the "actual" measurements before purchasing.

The size was not good. I won't buy them again.

Noticed a white powder on everything in my house after a few weeks of using this filter. My husband and I both ended up sick for 4 months with lung issues. I changed my filter to something different than these to see if they were the issue. Like magic. Lung issues cleared up and my house had no more white powdered residue!

The air filters fit well

The product delivery was excellent which is typical of Amazon's delivery service. This product works but it's expensive. I would have liked to have ordered the filter with the higher MERV rating but the expense was more than I could absorb. The biggest concern for this product is the cost is high.
