I can leave these air filters in the central heating and air conditioning system for 3 months before having to even think about changing them.
I recently bought some new air filters for my central heating and air conditioning system and they are very unique! You see they are compact. They come in a little box no bigger than a cigar box. And when you take them out they do not even look like air filters for your central heating and air conditioning system. They look like little mats for your kitchen counter or something like that. But what happens is when you untape them, they snap out into full on large size air filters! I really could not believe it! I simply and truly could not believe my eyes when I seen this happen! Wow! Want to talk about futuristic stuff, this here is exactly what this was in my humble opinion! However I will say that on top of these air filters being a good interesting show off thing at a party or gathering, they really work great. They are pretty close to the high end HEPA brand air filters in terms of quality as well as lifespan. I can leave these air filters in the central heating and air conditioning system for 3 months before having to even think about changing them. Not to mention they also improve and keep the air quality at bay in my home. Which is pretty good considering I do not have a whole home air purification system. These air filters are one of a kind that is for sure. And it makes me even more curious as to what else heating and air conditioning technology would bring us in the future.
