Collected by Trustpilot.comLove that they are delivered at certain times. Easy to install… except when they are damaged
Collected by Trustpilot.comWhen I installed our new HVAC I had an air filter (20x25x4) installed in the attic. The HVAC company recommended the use of the Honeywell filter. This is a great product ;and I replace it every 2 to 6 months, depending on the air quality. This filter worked well to filter out much of for soot and ash from the poor air quality from wildfires in the area. During those times. I sometimes had to replace the filter every month due to the sooth from the fires. The availability and the price at Filters Fast are outstanding.
