A whole-home air purifier cleans the air for the entire house as it passes through your furnace or air handler. The right type depends on what you want to remove: dust and pollen, smoke and fine particles, or germs. Here is how the options compare.

  • ✓ Authorized dealer for Mitsubishi, Panasonic, Bosch, Amana and AirQuest
  • ✓ Registered HRSP rebate contractor
  • ✓ TSSA-certified gas technicians, licensed and insured

🔍 Types of Whole-Home Air Cleaners

Type Removes Good to know
Media filter (MERV 11–13) Dust, pollen, pet dander, most fine particles Thick 4 to 5 inch cabinet; low maintenance; best value for most homes
Electronic air cleaner Fine particles and smoke Washable cells; needs regular cleaning
HEPA bypass unit Very fine particles Separate unit tied into the ducts; highest filtration
UV light Mould and bacteria on the coil and in the air stream Keeps the coil clean; does not remove dust

🏠 Which One Fits?

Concern Usually best
Allergies, dust, pets MERV 11–13 media filter
Wildfire smoke, fine particles High-MERV media or HEPA bypass
Musty smell, mould on the coil UV light plus a good filter

A higher MERV filter needs a properly sized cabinet. A thick, tight filter in a 1-inch slot restricts airflow and strains the blower.

🛠️ Maintenance

  • ✓ Media filters: replace every 6 to 12 months
  • ✓ Electronic cells: wash every 1 to 3 months
  • ✓ UV lamps: replace about once a year

💡 Fresh air matters too. Pair a filter with an HRV or ERV for a complete indoor air quality setup.
