  • Air Cleaners – Featuring a MERV 15 filter and patented Captures and Kills technology, the Carrier Infinity air purifier cleans indoor air as often as eight times every hour, trapping up to 95% of particles that are up to 18,000 times smaller than a pinhead and destroying up to 99% of captured germs, pollen, and mold spores.
  • Energy Recovery Ventilators – Carrier Performance & Comfort series ventilators remove stale air and supply fresh pre-conditioned air, reducing the workload of your HVAC system, effectively managing humidity, and greatly reducing the number of indoor air pollutants.  You’ll enjoy the benefits of opening a window, with none of the drawbacks.
  • UV Lights – Installed into your HVAC system, Carrier UV lamps eliminate contaminants before they are introduced into your indoor air and prevent microbial buildup on the indoor coil and drain pan of your air conditioner, preserving efficiency.  You’ll avoid the need for chemical coil cleaning, spend less on monthly cooling costs, and enjoy a healthier supply of indoor air.
  • Humidifiers – The investment into a Carrier Performance series steam, fan-powered, or bypass humidifier quickly pays for itself.  Regulating moisture levels allows lower thermostat settings without giving up on comfort.  Maintaining humidity within the ideal range also benefits your health, hair, and skin, protects fine wood furnishings and low voltage electronics from damage, and improves the enjoyment of your home.
