[Canadian Tire] 3M Filtrete™ Micro Allergen Filter MPR 1000, 20x20 Dual Pack ($19.99) (YMMW)

Perfect for those who got the Bed Bath and Beyond box fan deal and looking to do a DIY air purifier. This was at the Leslie and Sheppard location, unsure if it’s on sale anywhere else, YMMW. 20x25 size was also on sale for $19.99.

Or or just get the merv 11 that's not on sale and under 20$. That way the little guy wins one against shady 3M?


Note: I'll always post this. 3M sells MERV rated air filters to businesses. They claim there's an equivalence with MPR. They did the research. They never released the research. It's been years. What reason would they have to go and invent a whole new filtration rating system and when one is already in existence, centrally managed and approved and in use BUT they only sell this new system to residential customers?? It has that smelly smell that smells
