3M’s Innovative Air Filtering Technology Has Been Incorporated in LG’s Most Efficient Air Conditioners

The home should be a sanctuary. It should be a place where a person can come to after a hard day at work and find comfort, peace and relaxation. Yet for some people, home is anything but relaxing. The air feels stuffy and unpleasant. Rooms are filled with odd smells. Stale air, mildew, cooking residue, body odor and other unwelcome, nose-crinkling scents abound. Pet hair and dust get in the eyes. Noses get congested. Throats get irritated. Headaches form. Something needs to change!

The air we breathe has a direct effect on our health. Much of the world’s population now spends the majority of each day inside closed, indoor environments. Unfortunately, the air quality inside buildings, including homes, offices and schools, is often surprisingly poor. In fact, it is not hard to find higher levels of pollution inside than out. Comparative studies of indoor and outdoor air quality conducted by the by U.S. Environmental Protection Agency (EPA) have shown that the amount of pollutants present in an indoor setting may be two to five times as great. According to the EPA (, indoor pollution stems mostly from the presence of potentially harmful gases and airborne particles.

Nowadays, advanced air purification technologies can be found in residential air conditioners. Many air conditioning manufacturers are adding air filters to their products; however, an advanced filter has traditionally had an adverse effect on cooling and heating capacities due to its density.

Joining Forces for Healthier, Cleaner Air

LG Electronics teamed up with 3M, an innovator in filtration technology, to produce a highly efficient, cutting edge filter for air conditioners. With the implementation of this effective new filter, LG’s latest residential air conditioning products offer exceptional cooling and performance while helping purify the air.

“LG has developed and released a range of air purifying technologies over the years, helping to combat a number of dangerous airborne bacteria and even viruses such as H1N1. Yet, it has proved a very difficult and time-consuming process to successfully apply the most sophisticated clean-air technologies to a residential air conditioning unit,” said Hyung-ho Park, Principal Research Engineer at the LG Air Conditioning and Energy Solution Company. “In the past, we found that incorporating  air filter caused air cooling performance to suffer. For that reason, LG has spent a considerable amount of time and energy since, developing new technologies – ones that won’t negatively impact cooling performance.”

To overcome this obstacle, LG partnered with 3M. 3M has a strong presence in the world’s automotive air filter market and offers advanced air filtration technologies. These technologies protect the consumer from unhealthy dust particles; they capture allergens and microscopic particles that can carry bacteria, viruses and unpleasant odors. In August of 2009, LG and 3M agreed to develop a new, highly efficient air filter for use in LG air conditioners. The new filtration system would be able to ensure a higher level of clean air without detracting from the powerful cooling capabilities of LG’s industry leading AC products. Experts at both LG and 3M commenced joint collaboration in earnest.
