A Memorable Installation Showcase

I’m a seasoned ARC-FLASH photocatalyst technician, and I often receive calls inquiring about indoor photocatalyst treatment services. If you’re one of the many who’ve called before, chances are you’ll recognize me from this blog post.
Because of my hands-on experience in photocatalyst applications, I’ve developed a solid understanding of formaldehyde mitigation—whether it’s identifying sources in newly renovated homes or recommending effective solutions. Whenever I pick up a call, the conversation almost inevitably turns into a deep dive on formaldehyde issues, often lasting over half an hour. One call that left a lasting impression came from Ms. Li, who had just moved into the Nordic Community in Hsinchu.
Ms. Li was incredibly diligent. Like many new homeowners or those planning a renovation, she was determined to create a comfortable living space. But her level of care stood out. Never underestimate the meticulousness of a woman—her thoroughness often surpasses us guys who tend to overlook the details. Faced with the issue of formaldehyde from interior finishes, she had already done extensive research online. So when she called, she went straight to the heart of the matter. It was immediately clear she had done her homework.

We discussed a wide range of factors that contribute to formaldehyde emissions—what types of interior finishes tend to release it, how changes in daily habits can influence indoor levels, and even how increasingly hot summer weather can accelerate the off-gassing from building materials. Ms. Li took all of this into account and carefully avoided any construction methods or materials that might raise formaldehyde concentrations indoors.
Then, just before moving in after the renovation was complete, she called me again. She said, “I followed everything we discussed during the planning stage. I avoided anything that could increase formaldehyde levels. So the concentration shouldn’t be too high, right? Plus, I spent fifty to sixty thousand installing a total heat exchanger. So… do I still need photocatalyst treatment?”
Well… how should I respond to that?
After thinking it over, I told Ms. Li, “It sounds like you’re looking for a reassuring answer to ease your worries. This kind of question feels like you’re hoping I’ll say, ‘No need for photocatalyst treatment.’”
Of course, I’m a technician—not a salesperson—so I don’t push photocatalyst services just for the sake of selling. I prefer to share my experience and knowledge about formaldehyde and photocatalysts, and let clients make their own informed decisions.
Here’s what I suggested: if the indoor air ever feels uncomfortable, open the windows and turn on a fan. It’s a simple and effective way to improve air quality immediately. (This is a tip I often recommend to homeowners—definitely worth remembering.)
A few days later, Ms. Li called again and said, “Mr. Liu~~ When’s the earliest you can come to my place for the treatment?!”
