Is it right for your home?

A whole-house air quality product works through your furnace or air handler, so it treats every room the system reaches. It helps most when:

  • Someone in the home has allergies or asthma
  • You have pets
  • Dust settles again soon after cleaning
  • Winter air brings static shocks and dry skin
  • Cooking or pet odors linger
  • Wood floors and trim open up gaps in winter

On any service visit, our technician can check your current filter and talk through what would help.

Purifiers, humidifiers and filters

Whole-house air purifiers

ICS installs whole-house air purifiers from AprilAire and Aerus. The AprilAire Model 5000 uses a MERV 16 filter, the highest MERV rating, to catch fine dust, pollen and pet dander.

The Air Scrubber by Aerus mounts in the ductwork and circulates ionized hydrogen peroxide to inactivate viruses, bacteria and mold and to cut odors from pets, cooking and cleaning products. Its technology was inducted into the Space Technology Hall of Fame in 2017.

Whole-house humidifiers

Running the heat dries out indoor air over a Lehigh Valley winter. An AprilAire whole-house humidifier mounts on the furnace and adds moisture while the heat runs. Its automatic control adjusts to the outdoor temperature to keep your windows from fogging.

Media air cleaners

A 4-inch media cabinet with a MERV 11 filter replaces the thin filter slot at your furnace. Its larger filter catches about 21% more particles than a standard filter, needs changing less often, and eases the strain on your blower and ductwork.

Surge protection and leak alerts

A surge protector with a voltage monitor guards your system's electronics against power spikes and records power problems you can show the utility. A Wi-Fi water leak sensor alerts your phone if it finds water, such as from a clogged condensate drain.

Frequently asked questions

How often do whole-house filters need changing?
A 4-inch media filter usually lasts six to twelve months, compared with one to three months for a standard 1-inch filter.
Will I hear a whole-house air purifier?
No. It sits in the ductwork or at the furnace and runs with your system's fan, so it's no louder than the system itself.
Can a humidifier cause mold or condensation?
Not when it's set correctly. An automatic control keeps indoor humidity in a healthy range and lowers it as the outdoor temperature drops, which keeps condensation off your windows.
Can these be added to my existing system?
Yes. Purifiers, humidifiers and media cabinets install on most existing furnaces and air handlers, usually in a few hours.
What does it cost to run?
Very little. The main ongoing cost is replacement filters, plus a replacement cell or bulb on purifiers that use UV light.
