Fighting for air filters in schools showed me why Alberta needs an unfiltered public health office

This column is an opinion by Paul Lu, a college professor in Edmonton. For extra details about CBC’s Alberta election 2023 opinion sequence, go to the My Precedence house web page.

For issues that require deep experience, we have to have impartial voices that may communicate freely. Auditors basic, for instance, have nice freedom to research and report on authorities operations and spending. 

Just lately, the COVID-19 pandemic and opioid disaster have proven the necessity for a completely impartial officer of public well being whose suggestions are clear and offered with out political interference.

Within the fall of 2021, I realized this firsthand once I joined different dad and mom to advocate for high-efficiency particulate air (HEPA) filters in Edmonton’s college school rooms.

As dad and mom, we had been involved about our youngsters spending hours in a classroom, consuming lunch maskless. We needed a number of layers of safety in opposition to COVID-19, influenza and air air pollution, resembling wildfire smoke. Like 1000’s of Alberta households, we already had HEPA filters in our properties.

As a professor, I’ve privileged entry to the unvarnished opinion of specialists at my college and am used to looking for them out for interdisciplinary analysis. Due to this fact, it was pure to hunt out specialists in air filtration from engineering, and specialists in COVID-19 from drugs. 

Not all the specialists that I spoke with agreed with the cost-benefit of HEPA filters, nor did they utterly agree with one another. Some specialists had been, to my shock, involved that HEPA filters would possibly improve an infection charges. Then I reached out to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and requested for a clear assertion of the case for HEPA filters. 

In the end, because of the advocacy of many dad and mom, the Edmonton Public Faculty Board (EPSB) allotted $6 million to put in air purifying models in any respect 213 of its faculties. Now, a yr after rolling out the filters, there may be rising proof of the numerous advantages of improved indoor air high quality for college students. 

Nonetheless, some college boards in Alberta proceed to withstand putting in even donated HEPA filters.

Navigating a sophisticated world

When there are totally different factors of view and complex proof, the flexibility to listen to instantly and totally from specialists is paramount. 

Politicians and trustees nonetheless make the selections, however allow us to rent the proper individuals and provides them the independence to tell the general public. There’s a bigger debate on what we would like from our public well being specialists, however allow us to begin with the premise that these specialists must be clear of their suggestions and reasoning.

On the subject of HEPA filters, there was no clear, public assertion from the workplace of the Chief Medical Officer of Well being (CMOH) of Alberta on whether or not air filtration may very well be carried out correctly and successfully.  In distinction, the federal Public Well being Company of Canada included air filtration, citing ASHRAE, in its public suggestions  and infographics.

It was straightforward for some college leaders to delay motion when there was a scarcity of clear steering from higher-level officers. The dearth of a transparent place from the CMOH’s workplace made it onerous for our group of fogeys to advocate for HEPA filters. That experience vacuum was a barrier.

Due to this fact, there must be a revamped workplace of the Chief Public Well being Officer (CPHO) in Alberta with its independence enshrined in laws. I’m not an knowledgeable on the main points of the Auditor Common Act however I hope the voting public can agree that we’d like a CPHO that’s no less than as impartial because the auditor basic. 

The purpose of an impartial CPHO is to not help anybody viewpoint.

Throughout Canada and the world, there have been vastly totally different approaches taken by chief medical officers and public well being officers. The introduction and elimination of limits on public gatherings, for instance, assorted from province to province early on within the pandemic. I supported a few of these approaches, and I’ve been dismayed by different selections. 

Politicians usually say that they’re following the recommendation of public well being officers, however it is vital for the general public to see the precise suggestions instantly and in a well timed style.

When an auditor basic finds examples of waste in authorities, neighbours can disagree on tips on how to maintain the federal government accountable, but it surely shouldn’t be doable for the federal government to say “cupboard privilege” over that report.

Let precise cupboard discussions be non-public, however let the suggestions of the CPHO be public.  Freedom of knowledge requests and lawsuits are too sluggish in a fast-changing emergency. 

Future pandemics and epidemics would require a robust CPHO. Our elected officers want entry to that experience, however the public additionally must see the unvarnished suggestions with out authorities interference.

My Precedence

What’s the one factor meaning probably the most to you by way of the provincial election and why is that? We recruited over a dozen residents from throughout Alberta to reply that query. Learn their opinion items as they’re printed at

Bear in mind, these items shouldn’t be taken as endorsements of any explicit political get together by both the writers or the CBC. They’re expressions of the writers’ factors of view, and a have a look at how these opinions got here to be fashioned.
