Furnace filter

While I was looking online through several websites to see if I could find a gas furnace filter for sale, I came across a single that looked too nice to be true… Also, the price was rather high for a single gas furnace filter, and the filter was called the ultimate gas furnace and a/c filter, but first off, how in the world can a gas furnace and an air conditioner system run off the same filter? It was saying that the filter could be used in both a gas furnace and a central air conditioner system.

That makes totally no sense to me, and now I am no Heating and A/C specialist or expert, however regular sense tells me this is not possible, but or, who knows, maybe it is, with the way the Heating and A/C technology of today is going; But the price of this thing is what got me the most.

They wanted almost a single hundred dollars for a single single air filter! I seen and learn some reviews on the website about this so called miracle filter. Oh, did I mention, they also said it is a washable air filter too. The reviews were mixed. Mostly good reviews praising the product, however, you don’t recognize how several of those website reviews are real, and which a singles are fake sited there by the business, but so, I stuck with studying the exhausting reviews and medium rated reviews on this miracle gas furnace and a/c filter. At least those I recognize were real. Surprisingly, this filter is not a rip off or some kind of scam. Though, it’s not what it’s cracked up to be. So i’ll pass on it.
