This has been really fascinating. 00:39:45 Brent Bauerband: you are probably going to show this, but what is the hierarchy of effectivity for the various solutions 00:39:55 Kasim Aslam: Yes! We'll be including links to the full talks on our Town Hall page 00:40:02 Elise Arevalo: Great thanks! 00:41:09 Alicia Davis Enright: How can we stay informed about the development of your new system? 00:41:14 Elise Arevalo: How large do we need for a classroom? 00:41:16 Kimberly Kleiber: How can we figure out the Air Change Rate of a current system? 00:41:38 Peter Flotten: Are you familiar with ActivePure technology by Aerus? 00:41:39 Denise Spetrino: is there a way to add UV capabilities to an existing HVAC system? 00:41:50 Karen Duca: Thanks very much, have to run, but really appreciated learning from Paul. Thanks! 00:41:51 Denise Spetrino: Is UV CDC approved to kill the virus? 00:43:23 Susan Locke: UV in an HVAC system if possible to implement, safe to run when people are present? or can that portion be run separately from regular ventilation? 00:43:51 Elise Arevalo: We are adding UV to our HVAC, but not sure how it works. 00:44:30 DANIELLE BENGE: The Halo air purifiers where discussed at a previous town hall. I am having them installed in our HVAC system. 00:46:17 DANIELLE BENGE: I was told by our HVAC people said that a MERV 13 will constrict our air flow. 00:49:18 Susan Tracy: Is there any beneficial advantage to leaving an outside door open 00:49:18 Alicia Davis Enright: We are a small school and do not have a Facilities department, so where would you suggest I go to get answers to these questions? Should the company that services our furnace be able to answer them? 00:50:38 Melissa Davis: What would you say to people who believe that there is a danger to those wearing a mask because it holds the pathogen on the face? 00:52:25 Rachel Lochtefeld: We have steam heat with returns right next to the registers and all are right under the windows. Is there anything we can do to improve this situation? 00:52:40 DANIELLE BENGE: What change rate do we want? 00:52:53 Robin Stearns: How do we find a company to evaluate HVAC system 00:54:12 Brent Bauerband: is it better to try UV and spend money rather than air changes 00:54:26 Syed Haider: If we have UV lights in the duct, do we still need MERV 13 filters? 00:55:00 DANIELLE BENGE: I agree, thank you! 00:55:05 Tori Inkley: Many Montessori schools are housed in non-traditional buildings (e.g., churches, houses, other types of buildings) without HVAC systems. If that is the case, what should the priority be for ventilation and air change? 00:56:04 Hillary Drinkell: I have to leave, but most appreciate this presentation and information. 00:56:08 Susan Locke: So, we have a free standing blue light/ozone. which is quite potent, and can run 15 30 or 1hr. we have to stay away from that room for at least an hour to 2 afterwards. is the free standing much stronger than in the HVAC? we get concerned for those with asthma etc. 00:56:10 Brent Bauerband: would you spend 10K on fan upgrade vs 10K on UV 00:57:15 Debbbie Parga: we do not have A/C, but we do have a heating system. What should we be preparing? I have changed filters and plan to open windows for outside air. 00:58:15 Meghan Smyth: UV vs. MERV-13 filter...same thing? 00:59:20 Kimberly Harrell: Take care everyone and stay safe. 00:59:31 Melissa Davis: Thank you! I agree! 01:00:54 Tori Inkley: All pipes 01:01:09 Tori Inkley: Window Acs and radiator heat 01:01:18 Karen Bridgeo: Hollis Montessori 01:05:33 Alicia Davis Enright: What is the humidity level we should be striving for to reduce risk? 01:05:51 Elise Arevalo: I think he said between 40-60 01:06:01 Debbbie Parga: Thank you!!! 01:06:09 Alicia Davis Enright: I missed that. Thanks! 01:06:20 Elise Arevalo: =) Sure thing. 01:06:50 Susan Locke: quick. how many nm should the UV in the HVAC be? 01:06:53 Sadiya Muniruddin: Thank you! 01:06:57 Charlane Baccus: Thank you this has been very informative 01:07:23 Susan Locke: thank you 01:07:26 Martha Winters: this was super helpful, as always! thank you! 01:07:40 Lynn Nehez: Thank you so much!
