They say the best kind of filters for your heating and air conditioning system are HEPA filters. I can verify from experience that this is totally true every which way. I have been using HEPA filters for a long time now, and they are certainly the best! HEPA air filters were introduced to me by a certified heating and air conditioning specialist I once had working on my home’s heating and air conditioning equipment. After experiencing these wonderful HEPA filters for so long, I was curious about looking into other kinds of filters. I found something that I didn’t quite understand what it was, but it looked interesting! It was something called a HEPA filter intake box. If I wasn’t so lazy, I would actually go look on the internet at websites and surf through several live links to find more information on HEPA filter intake boxes. But, as I said, I am pretty lazy and really do not feel like it at this time. But the one thing of HEPA I do know about and actually have is one of the HEPA allergen removers. Also known as a portable air purification system. That HEPA air purification system is really nice. From what a friend of mine told me, those HEPA air purification systems work just as well as the whole home air purification systems, if you place them correctly throughout your home. You could say I am a true fan of anything HEPA has to offer! Now, just to find out about that HEPA filter intake box!
