A Lennox® PureAir™ whole-home air purification system improves indoor air quality better than any single system you can buy. Many technologies only combat one or two categories of air contaminants, and often only in a single room. The PureAir air purification system is the only single indoor air quality system to combat all three classes of indoor air contaminants—particulate, bioaerosols and Volatile Organic Compounds (VOCs). The PureAir air purification system reduces indoor air pollutant levels through a combination of hospital-grade filtration and a contaminate removal process called photocatalytic oxidation (PCO). The process involves three steps. Step one, the Carbon Clean 16® filter captures particles and bioaerosols as small as 0.01 micron, removing them from the airstream. Step two, as the odor-and-chemical-vapor-filled airstream flows through the PCO cartridge, the airstream is exposed to the catalytic surface (titanium-dioxide-coated PureAir cartridge). Step three, the light energy from the UVA lamp and catalyst work together to break down odours and chemical vapours into harmless carbon dioxide and water. Unlike other air purification products on the market, the PureAir system does not produce any ozone as a by-product and actively works to reduce ozone, a known lung irritant.

Proper Humidity Control Can Mean Lower Energy Bills
When your home’s humidity levels are maintained at an optimal setting, you’ll not only feel more comfortable, but you’ll also be able to keep your thermostat at a more energy-efficient setting.
More Moisture in the Winter Means More Comfort
A Healthy Climate® humidifier works with your heating system to keep the air inside your home from becoming too dry and causing wintertime chapped skin and respiratory problems. Plus, it’s more effective and easier to maintain than a portable humidifier.
Sticky Conditions Outside Call for Lennox® Innovation Inside
Designed to work with premium Lennox® equipment, the Humiditrol® whole-home dehumidification system uses patented technology to remove excess moisture from your home. Dehumidifiers are also available that work with all brands of heating and cooling equipment.
When your home’s air is properly humidified, your whole home feels better. Lennox® Healthy Climate® whole-home humidifiers and dehumidifiers efficiently control moisture levels in your home without producing ozone, a known lung irritant. In the wintertime, a Healthy Climate whole-home humidifier works with your HVAC system to add humidity to your indoor air, stopping it from becoming too dry and uncomfortable. In the summertime, a Healthy Climate or Humiditrol® whole-home dehumidifier removes excess moisture from the air, making your home feel less sticky and hot. Too much moisture in your home’s air not only makes the atmosphere feel heavy and damp, but it also promotes the growth of mold and mildew, which can aggravate allergy sufferers. Properly dehumidified air is not only healthier and more comfortable, but it can also reduce your summertime energy bills. Dehumidified air feels cooler, so you can set your thermostat at a higher temperature and still feel comfortable. In fact, for every two degrees you raise the temperature during the summer, you can save between 5% and 7% on your cooling bill.

A Refreshing Option for Healthier Air
Today’s newer homes are often tightly sealed for efficiency, but this can make the air stuffy. Also, allergens and contaminants can stay trapped inside. Healthy Climate® ventilation systems offer a simple and effective solution, replacing stale indoor air with fresher outdoor air.
Better than an Open Window
Opening a window can make your air feel less stuffy, but this isn’t practical during the hotter and colder months of the year, plus it invites pollen and other allergens into your home. A Healthy Climate® ventilation system offers a better way to enjoy the fresh air.
You Control the Comfort
With a Healthy Climate® ventilation system, you can easily adjust the amount of fresh air entering your home using simple, intuitive controls.
Freshens Without Producing Ozone
Unlike some indoor air quality systems on the market, Healthy Climate® ventilation systems freshen the air without producing ozone, a toxic gas that can irritate the lungs*.
Ideal for tightly sealed homes, Lennox® whole-home Healthy Climate® ventilation systems replace stale indoor air with clean outdoor air, making your home feel fresher and less stuffy. Better than opening a window, which can let allergens and bugs into your home, a Healthy Climate ventilation system allows you to easily and efficiently control the amount of fresh air coming into your home. Well-suited for colder climates and dry or desert-like areas, the Healthy Climate Heat Recovery Ventilator (HRV) harnesses heat from inside your home and transfers it to the incoming fresh air. This heat recovery process enhances your comfort and helps control wintertime condensation, which can damage windows, insulation and furniture. Ideal for warmer and more humid climates with mild winters, the Healthy Climate Energy Recovery Ventilator (ERV) transfers moisture and heat from incoming fresh air to the outgoing airstream. In fact, it can remove nearly half of the moisture from the incoming air, helping to keep your home cool and dry. Unlike some indoor air quality systems on the market, both the HRV and ERV systems freshen the air without producing ozone, a known lung irritant.

Air filters are essential components of your heating and cooling system. They help improve the quality of your home’s air and keep your system performing at peak efficiency. The most common air filters are standard disposable cartridges, but advanced filtration systems and air cleaners are also available.
When to Change Air Filters
Standard, one-inch disposable air filters should be changed every three months. However, if anyone in your family suffers from allergies, or if you have pets or dust buildup in your home, you might want to change your filters every month or so. Advanced filtration systems have longer life spans and are usually maintained by HVAC professionals.
How to Change Your Air Filter
The process for changing standard disposable filters is fairly straightforward and involves just a few steps:
Locate your air filter Air filters are typically located in your system’s return air vent, which might be on the ceiling, wall or on the side of your furnace or air handler. Your air filter might also be housed inside the unit. If this is the case, you may have to remove an access panel to get to the filter.
Remove the air filter from its housing Simply open the return and pop out the old filter. If there is no filter in return, measure the length and width of the space, so you’ll know what size filter you’ll need for replacement.
Note the size printed on the air filter frame If you removed an old filter, check its size so you can be sure you have the correct filter for replacement. If you have any questions about the size you need, you can refer to the owner’s manual for your furnace or air handler, or contact your local Lennox® Dealer.
Install the new air filter Securely slide the new filter in place of the old one, making sure you follow the arrows printed on the sides of the filter frame. These arrows point to the direction of the airflow, which should be toward your furnace or air handler.
Get help from your lennox® dealer If you have any questions about where your filter goes, or how to install a new one, your local Lennox® Dealer can help. If you have already replaced your filter, and your system makes excessive noise, contact your Lennox® Dealer to address the problem.
