Why Indoor Chemistry Matters is an important inflection point in how we look at indoor environments. For 50 years we have looked at CO and CO2 and Formaldehyde, Lead, Asbestos, particulate, mold and the elusive VOC's. Now we are seeing that grandma was correct and its all of these plus more and they...

Sometimes you are not sure how a show is going to go until you do it. This week was no exception and in the end it came out exceptional. The last day inclusion of Dr. Michael Berg was very helpful and his contribution along with Dr. Sothern and Chris Mikrut made for a great show. This is an importan...

It's always a pleasure talking to Brad Prezant. Upbeat and intelligent are just two words to describe him. What started out as a pretty technical show also included a bunch of practical information that can be implemented quickly. I will be using some of the things learned today when we open a new g...

Thank you Dave Jacobs not only for doing the show with us yesterday but for your decades of work helping make homes healthier. I love these kind of shows when we learn about what happened behind the headlines. Be it the Cleveland IPH topic or how the HUD Guidelines for Lead Based Paint came about to...

Always great to learn from Dr. Joe Spurgeon. All I can say is I hope more and more people learn from Joe's years of expertise. If only I had a magic wand and could get the industry to listen to Joe. And if only the alternative medicine docs would recognize the major issues with using ERMI Scores to ...

Great show with our guests Roger and Brian. It's always nice to hear from the man in the field doing this work on a daily basis. Mold remediation is tough work. I look forward to hearing the feedback from our audience as they try out the Dot products.

Nice to talk with Elliot Gall about particle and gas-phase pollutant mitigation topics today. Everything I learn on this topic makes me think we will be hearing more and more about it. The pandemic and the wildfires are making IAQ more important every day.

Our thanks to Andy Persily and Jon "You Gotta Have" Faith for this week's show. While preparing for last week's interview I found that our May 2010 interview held up really nice and decided to replay it as a Flashback Friday on Easter Weekend. Jon helped update it with photos, sound editin...

Wow, great interview and questions from our audience. I think we can let the Cliff's blog and the comments speak for themselves. I am working with Dr. Persily on follow ups to questions we could not get to today!

Great episode with a great guy and industry pioneer Don Fugler, You never know until its done how these shows will go, Our Founding Fathers/Pioneers and Legends shows have been classics. Today was no exception. I have been wondering about references for claims that hard flooring is easier to clean t...
