Pure Air At Last (Part 3)

So we covered death rays and holey carbon, now lets talk about how these two work together with the last component of the APCO In-duct Air Purifier system, titanium dioxide (TiO2). TiO2 is also present in the activated carbon. This is important because as you might expect, if the carbon keeps catching all the VOCs eventually it would run out of room for catching new odors. This is where the TiO2 comes into play. The chemistry for this part gets a little complicated, so we are going to do a bit of hand waving in this post. If you are interested in finding out exactly how catalytic converters work Wikipedia is the place to go.

Basically the TiO2 in the activated carbon uses the energy from the UV light and converts all of those volatile organic compounds into harmless carbon dioxide and water. This means that the only part that ever needs maintenance is replacing the UV lamp about every two years, which is why the rest of the device has a lifetime warranty. Replacing the lamp when needed means that for the rest of your life odors and viruses in any home with the APCO system installed are eliminated. It’s better for your home, better for you, better for your kids, and better for your guests. Who could ask for more? Call us today to get an APCO In-duct Air Purifier system for your home.

Pure Air At Last (Part 2)

Last time we talked about solar death rays fighting off hordes of bacteria, mold and viruses. This time lets discuss smells; all the bad ones that slowly build up in your home. Smells are powerful. Research has shown that smells are the sense that is most strongly tied to memory. Do you want your home to be remembered because it had an odd odor? We didn’t think so. The second technology used by the APCO In-duct Air Purifier system is…(drum roll)… carbon. Activated carbon has several uses, but in the APCO it removes odors.

Activated carbon is used for all kinds of things: cleaning water, filtering chemical solutions for analysis, treating overdoses and poisonings, and as in the APCO removing chemicals from air. Now, brace yourself, incoming chemistry. Ready? Here we go. Activated carbon is full of micro pores. These tiny holes give 1 gram of activated carbon over 500 m^2 of surface area. More surface area means that there is more area for chemicals to react to. And carbon is very good at reacting with volatile organic compounds (VOCs). When the VOCs react with the carbon in the APCO they get stuck and removed from the air. Since the VOCs cause the smells, and the VOCs are stuck in the carbon; the smells are gone. Whew…chemistry over. Did you make it? Glad to hear it. Next time we’ll talk about why the carbon can keep catching the VOCs.

Pure Air At Last (Part 1)

Let’s talk about air. Not just air, but clean air. BNG has always offered a wide variety of products to clean and purify your air. We would like to introduce a new product, the APCO In-Duct Air Purifier from Freshaire UV, winner of the AHR Expo Innovation Award for 2011. The APCO purifier uses three different technologies to clean the air in your home and so there will be three blog entries to address it.


First APCO uses UV lights, or as they are known to mold, pollen, viruses and bacteria: solar death rays! The UV light hits the bacteria or virus that is airborne and destroys its genetic material. Since the virus or bacteria can no longer replicate it can’t affect you. New York City is spending 2.2 billion dollars on a UV purification system for their water, so the technology works. Also, we offer a surprisingly large discount from the 2.2 billion dollar price tag New York is paying.  That about covers it for solar death rays…we mean UV lights. Solar death rays sounds a lot cooler though.  Next time we’ll talk about stink or getting rid of it.
