In our first epoch episode, (April 16, 2020 at 8 PM EST) will talk about the elephant in the room.  Even though the show will be all things artisan related, (construction, renovation, maker stuff) we can talk about related subjects such as the structure of the virus and whether it can be filtered from our living spaces.

 2. About Filters Ratings Links

MERV stands for Minimum Efficiency Reporting Value.  It's an acronym created by ASHRAE to provide a scale showing the effectiveness of filters at removing particles of different sizes.  The range of sizes in the MERV scale is 0.3 µm to 10 µm, subdivided into smaller ranges.

2A Corner 

Speaking of foundations, (pardon the pun)  the 2nd Amendment is the foundation of our freedom and we will always take a minute to remind our listeners of this.  We will dedicate this segment of our show to the 2nd Amendment, even if it is just one of our favorite quotes or a though of the day. 

“The biggest hypocrites on gun control are those who live in upscale developments with armed security guards -- and who want to keep other people from having guns to defend themselves. But what about lower-income people living in high-crime, inner city neighborhoods? Should such people be kept unarmed and helpless, so that limousine liberals can 'make a statement' by adding to the thousands of gun laws already on the books?”
