Review on 🌬️ Highly Efficient 18X18X1 Pleated Furnace Filters by FilterBuy by Michael Caste

Filter too small to open. Purchased filters 12x12x1, 18x18x1 and 18x24x1. They indicate the actual size of the filters, which is smaller than the sizes given when reading the appendix. The question is to list them as a standard size and then make them slightly smaller. material savings? I buy filters from big stores, both from well-known brands and their brands, and have never had a problem. I bought these to limit exposure to the Covid19 virus. I try to stay at home. I will not buy these again. I had to tape the goods to the return hole with tape.
