HEPA filters and electronic air cleaners (EAC) both reduce airborne particles — but they work differently. Here is how each helps Calgary homes, and how to choose.

Why indoor air quality matters
Poor indoor air can worsen asthma and allergies, and leave the house feeling dusty even after you clean. The EPA ranks indoor air among the top environmental risks for families — and Calgary’s long sealed-up winters make filtration matter more.
- Worsening asthma, allergies, and other respiratory symptoms
- Headaches, sinus congestion, sneezing, and cough
- Eye, skin, nose, and throat irritation
- Fatigue when the air feels stale
What HEPA means
HEPA (High Efficiency Particulate Air) filters force air through a dense media that captures pollen, pet dander, dust mites, and smoke particles down to about 0.3 microns. They are a strong choice for allergy-prone homes and families with pets or infants.
HEPA strengths
- Traps allergens without chemicals
- Helps with pet dander
- Useful for protecting sensitive lungs in young children
What an electronic air cleaner (EAC) does
Electronic air cleaners charge particles and pull them onto collection plates — more like a magnet than a mesh. Many pair with UV for coil and airstream treatment. They often maintain better airflow than the densest media filters because they do not rely on packing the filter face.
EAC strengths
- Strong allergy symptom relief when sized and maintained
- Less airflow restriction than many high-MERV media packs
- Keeps coils cleaner, which helps system efficiency
HEPA vs EAC — how to choose
There is no single winner. HEPA media is straightforward and effective for particulate capture. An EAC can suit homes that need high capture with less static pressure on the furnace blower. The right answer depends on your equipment, duct layout, and health priorities — that is what an in-home consult measures before anything is ordered.
