So far so good, the filters came in fast and correct. I guess all I need now is to see how well they last... Prices were good if you buy in bulk... Excellent service.
Have been using these filters for a few years now. Great filters, great price, great service and quick shipping. Husband and I have some lung issues and I feel since using them, ( I change them monthly because of our problems,) we have had many less exacerbations.
