Building a air purifier system for your home is easy (and affordable!). In this video, I'll take you step-by-step so you can build your own. Download the Start Preparing! Survival Guide here: cityprepping.t... ... Start your preparedness journey: cityprepping.t...
Here are the items I purchased:
* Merv 13, 20x20x2 air filters: cityprepping.t...
* 20" box fan: cityprepping.t...
* Duct tape: cityprepping.t...
