I have created a step-by-step guide to building a #CorsiRosenthalBox . Thank you @JimRosenthal4 & @CorsIAQ for approving it. Displaying it in waiting rooms, offices, schools, and libraries will help more people stay safe this season. Please DM me if you need a PDF or another size.

A #CorsiRosenthalBox can also help with poor indoor air quality due to #wildfires . Here are the instructions (in English and French) to build one and protect yourself from the harmful effects of PM2.5. If you live in the GTA, I can build one for you at cost.

Huge thanks to @JimRosenthal4 for sending me frame edges to make four 10 x 10 filters by cutting one 20 x 20 @3M Filtrete MPR 1900 filter. I also found fans in the US at a great price. I can now make Mini #CorsiRosenthalBoxes for $43 CAD (3M filters) or $30 CAD (MERV 13 filters).

@AranetIoT @soveryart The cost of the case is around $2 CAD. You can pick it up in Mississauga. If you need it mailed within Canada, I will have to find out the postage. Mailing in the United States costs around $5-$6 USD. My grandparents can do it when they visit in a few weeks.

@johne_erhardt @CorsIAQ @JimRosenthal4 It is difficult to orient the fan upwards because the Comfort Zone fan has legs that cannot sit on the filter. I will create another set of instructions for the Black and Decker 9-inch fan, which I think can be placed facing up.

@prof_reed @CorsIAQ Did you use a shroud over the fan? Here is some guidance on the size of the shroud:

Important! Get the most out of your #boxfanfilter with a shroud on the outlet. Improves inlet flow & reduces power and noise. I've found optimum size for two models. Same final flow. Utilitech/Hurricane: 13.5" dia, +47% flow Lasko Comfort: 15" dia, +38% flow

@EatKS @CorsIAQ Thank you for your kind offer. I will let you know once I set something up. I want to make sure the boxes go to those who are unable to afford it.
