- Deep 4 3/8" construction provides more filter media and surface area for collecting dust.
- High dust-holding capacity helps the filter last longer between replacements.
- Hydrophobic polyolefin fibers do not absorb moisture and are cellulose-free.
- Structured density gradient helps maintain filtration efficiency throughout the life of the filter.
- Made in Canada. A Canadian-made alternative to the original Honeywell filter.
3 filters. About 18 months of filtration.
Each filter is designed to last approximately 6 months under normal residential conditions.
With 3 filters per box, one box can provide approximately 18 months of filtration.
The manufacturer states that the filter can last up to one year in standard applications. Actual filter life will vary depending on your home, airflow, pets, dust levels and other conditions.
Check your filter regularly and replace it when it becomes visibly dirty or when airflow appears reduced.
What does MERV 11 mean?
MERV is a rating used to indicate how effectively an air filter captures different sizes of airborne particles. This filter is rated MERV 11 and is tested according to ASHRAE Standard 52.2.
- Household dust
- Pollen
- Pet dander
- Mould spores
- Dust mite debris
- Common airborne contaminants and allergens

More filter media for longer-lasting filtration
The filter has a deep 4 3/8-inch construction with a large amount of filter media. More surface area provides more space for collecting airborne particles.
Its structured density gradient and electret charge are designed to provide high initial efficiency and help maintain filtration performance throughout the life of the filter.
The manufacturer states that this filter has approximately 2 to 4 times the dust-holding capacity of most filters.
Why replace your filter regularly?
As a filter collects dust and particles, airflow can become restricted. Replacing your filter regularly helps maintain good airflow and allows your heating and cooling system to operate properly.
For most homes, changing the filter approximately every 6 months is a good starting point. Homes with pets, renovations, excessive dust or other conditions may require more frequent replacement.
Which way does it go in?
Look for the AIR FLOW arrow on the filter. The arrow should point in the direction the air is moving, toward your furnace or air handler.
