Learn More about the Importance of Indoor Air Quality

Poor indoor air quality (IAQ) can be the cause of numerous health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants in your home's air can cause dizziness, headaches and nausea, plus aggravate allergies and asthma.

Clean indoor air benefits everyone, even people who have never suffered from allergies. By removing airborne dust particles from the air, the amount of exposure the respiratory system has to them is greatly reduced.

Fortunately, there are several steps you can take to address potential IAQ problems:


The first step toward better indoor air is to identify the sources of air pollutants and remove as many as possible from your home. You can decrease the amount of dust and dirt in your home by cleaning and vacuuming at least once a week. You should also regularly wash bed linens and stuffed toys. If someone in your family is sensitive to fumes, you should safely store household products and use them only when necessary.


Today's modern homes are well-insulated and sealed to conserve energy, which means airborne pollutants have no way to escape. Lennox' ventilation systems help remove particles and bioaerosols by exchanging stale, recirculated indoor air with fresh, filtered outside air.


Although cleaning and ventilating helps reduce indoor air pollutants, these simple fixes are not cure-alls. Some contaminants are so small that they may escape through the vacuum or never land on a surface. Lennox electronic air cleaners and high-efficiency air filters capture even the smallest of particles and bioaerosols. Lennox germicidal lights kill them. And a Lennox air purification system goes a step further — it removes particles, bioaerosols and odors, and it destroys chemical vapors.


Improper humidity levels and high temperatures can actually increase concentrations of particles and bioaerosols. Lennox SignatureStat™ and thermostats regulate moisture levels and temperatures to improve indoor air quality and enhance comfort.


Are all air filters created equal?
There are several factors to consider when choosing a filtration system, starting with sensitivity to allergens. The more sensitive a person is to allergens, the greater the need for a high-efficiency filtration system.




Germicidal lights use intense ultraviolet light to sterilize surfaces.

Electronic air cleaners (EACs) are highly efficient and clean the air by taking recirculated air and passing it through a prefilter that traps the large pollutants. Then, ionizing wires give a positive electrical charge to the remaining particles. A negatively charged collecting section collects the particles.

High-efficiency particulate air (HEPA) filters are also very effective at small-particle removal.

Activated carbon and microbiocide-treated filters can also purify your homes air.




What are the benefits of installing a whole-house humidifier?

The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) recommends that you maintain a household humidity level between 30 and 60 percent. During extremely cold weather, your home loses humidity to the outdoors and the level may drop to as low as 10 percent. A humidifier adds moisture to your indoor air and can help relieve ailments related to dry respiratory membranes.


With central heating, people are confined indoors with unnaturally dry air for many months each year. Humidifiers help to keep comfortable levels of moisture in the air, which is essential for your respiratory health.

Whole-house humidifiers work like old-fashioned room humidifiers: They put moisture into the air, making harsh, dry air easier to breathe. And whole-house humidifiers use water mists instead of hot steam, which keeps the entire house at the desired humidity level—no more carrying a humidifier from room to room in the winter.
