Because of furnace filter size, it isn't one you can get off the shelf at the local hardware store. I also have allergies and these filters do a great job.

First time using whole house filters. Shipping needs to be improved. Every order I’ve had in past has been dented in the corners and this was no exception. Fortify your boxes please.

Actual size doesn't fit my furnace, so these filters are no good and will be thrown away.

Unfortunately, there was no label on the filter themselves, but the label is on the shipping box. I'm not sure if this is to save money but it was confusing on my part. Have not used them yet. Got them in advance. I bought them while on sale.

I have been using these filters for about 4 years. They are terrific. The amount of dust they pull out of the air circulating in our house is dramatic. We can immediately tell the difference in the air when we change them out. We are so glad we made the move from the thinner filters to this product.
