I do like the filters and think they are a good value. They do not come in a box that says for Allergy sufferers. I recommend that it is added “for Allergy Sufferers” on the wrapper or the outside box.

Too early to effectively rate these filters. They should last 3 months. But we live in the desert where dust is always a factor. So if we get 2 months of service, we are satisfied.

I have used these filters before and they usually last a little longer than the 3 months that they are rated for. Very good filters.

Product is great, delivery questionable. Product came in two shipments after making many stops from Indiana to Georgia, back to Cincinnati and then to Virginia...first shipment arrived in several days, the second in about ten days.

Two of our vacation rentals have the same filters so I just doubled the order to have enough of a supply to furnish both cabins. I love it that I can get all my filters for all of our various rentals/houses at the same place. Makes my job so much easier!
