Can’t I just install a HEPA air filter?

When the HVAC technician told me about the air purification system, the only thing I could think of was that it was a new air filter.

He wanted me to install a HEPA air filter instead of the regular air filter I had been using.

I told him that wasn’t what I wanted and asked if I couldn’t just put the HEPA air filter into my furnace and the AC unit. He told me that installing a HEPA air filter wasn’t that easy. Unless you have a newer HVAC system, they didn’t build the older HVAC systems to accept HEPA air filters. The HEPA air filter was thicker and had a heavier weave, which is why they can filter out a lot more dirt, dust, debris, allergens, and other things that get in the air. He said an air filter can capture the mold spores, but they can’t kill them. That’s where the HEPA air filter comes in. They built our HVAC system before people knew about the HEPA air filters. The prices are much higher, and most people don’t want that expense. With an air purification system, you get the HEPA air filter, and an added UV light which will kill all mold spores, mildew and other nasties that could escape into the air. I still wanted to just put a HEPA air filter into my HVAC system, but he wasn’t buying it, and I wasn’t buying his pitch to have an air purification system installed. Maybe I was being stubborn, but I had lived with all the nasties in the air for all these years, and decided an air purification system wasn’t for me.
