Review on 🌬️ Enhanced HVAC Filtration: FilterBuy 14X25X1 Pleated Furnace Filters by James Vilchez

They were issued by the CDC recommended for good air purification. I bought these because I had workers in my house during Covid and wanted to make sure most of the contamination was removed. (kitchen renovation). Then my stove builder came for 6 months. inspection and he said that although the filters are good for what I have used them for I should not continue to use them because they are very harmful to the furnace. He said to use the rest but they buy filters that are not that restrictive. In other words, cheap. They are better for the oven, but change them more often.
