"I recently purchased two Honeywell 4-inch filters for my furnace. After visiting several web sites, I found the Alpine Air web site to be very informative about filter options. So, I bought two of the Honeywell filters shown in the attached photo. I found the package deal of two filters to be among the lowest price I could find on the Internet. I now change the filter every six months and am in my second year of filter purchases from Alpine. Your customer service has been great. When one shipment arrived crushed by the shipping company, Alpine replaced it at no cost, no questions asked.
You have been great to deal with, and I expect to be a repeat customer for years to come."
