Winix 115115 Genuine Replacement Filter A — A Full Year of Filters, Half Price! $42.73 CAD (53% Off)

Amazon.ca currently has the Genuine Winix 115115 Replacement Filter A set for $42.73 CAD (list $91.00, 53% off). Prime members get free shipping; non-Prime orders ship free over $35 CAD.

One box covers a full year: a single True HEPA filter plus four carbon filters, made for Winix models like the 5300-2, C535, 6300-2 and P300. The HEPA layer traps pollen, dust and pet dander; the carbon layer handles cooking, pet and smoke odours.

Winix recommends changing the HEPA filter once a year and the carbon filters every three months, so this kit matches that cycle exactly. Filters are where an air purifier actually costs money over time — the unit is a one-time buy, the replacements aren't. Picking up a set on sale beats paying full price when yours is overdue.
