We live in Central New Mexico and we often get smoke during the wildfire season. I have tried many smoke filter products in our home which is pretty tightly closed but! After installing these filters (it took us two because they didn't fit my oven) our air became very tolerable. Since the air conditioning or heating doesn't come on often, we turn on the fan for a few minutes a few times a day to filter the air and it works great. I would highly recommend these filters to anyone with smoking related allergy issues. They are a lot heavier than regular oven filters and it would be nice if they offered a size that fits my needs. I think buying one filter is cheaper than buying two. Perhaps the weight discourages them from offering a larger item.
