LOVE they are MADE in the United States of America!They filter out A LOT of stuff I already see a difference from my store bought filters these filters I have less dust in my house! I keep my windows open a lot but when I close them usually the dust is stupid there is so much. NOT with these filters! Thank you for a great product and fast shipping!
We completed an additional duct that was not completed when the house was built. This filter is being used with this duct. It fits well and is very easy to replace. We will purchase this again when needed.
I'm unsure if my home is really dusty or I'm over reacting but I would not leave the filter in for more than 60 days. Perhaps this means that the filter is just great or I don't understand dirty.
Not sure how to tell if it is better? I am afraid the higher quality filter will restrict the air flow and result in other problems. Like over working the fan motor.What things should I notice to prove this filter is better?
