K&N HVAC Filter Cleaner 32 Oz Spray Bottle Restores Home Air Filter Performance 99-6010

For those that do not know what this is for it is for a lifetime warranty HVAC filter, but you must use this every 60 to 9 days. I was skeptical paying $50 for one filter but once you see it, you'll realize you why it's worth it the workmanship as in the material like real metal and very thick card not like any other cotton. It was completely soaked after 60 days now it's completely white like you have to brain you again instead of paying 12 or more dollars every month as long as you use this, it's a lifetime guarantee even if it lasted five years you save so much money and they also have different nerve ratings as well but I got more. I can tell you that Murph told I was bond or not Merv 12 compared to this thing if that's the rating scale this is like a murder 100 for those that do not know what this is for it is for a lifetime warranty HVAC filter, but you must use this every 60 to 9 days. I was skeptical paying $50 for one filter but once you see it, you'll realize you why it's worth it the workmanship as in the material like real metal and very thick card not like any other cotton. It was completely dirtyy after 60 days now it's completely white. I used to pay $12 for those Merv 12 filters once. A month. I know it's gonna last at least five years but as long as you use the spray lifetime guarantee.. also compared to the Merv 12 my Merv eight is at least five times the thickness I'm talking about the cotton what you used to catch the particles.
