CNA938 Rewind - Exploring the Science of Clean Air with FJ SafeSpace
CNA938 Rewind - Exploring the Science of Clean Air with FJ SafeSpace In 'Made in SG', Melanie Oliveiro speaks with Jay Choy, founder of FJ SafeSpace – providers of premium air quality monitoring solutions. Choy will recall how and why he went into the advanced air purification sector after getting retrenched from his sales job. He'll talk about the science behind photoplasma technology, and how it combats hidden threats like viruses, bacteria, fine dust, Volatile Organic Compounds (VOCs) and odours. Choy will also talk about how FJ SafeSpace has carried out over 140 indoor air quality assessments across homes, offices, childcare centres and industrial sites.

Edmonton weather: Partly cloudy and hazy with some showers on tap
The Air Quality Health Index rose to the high risk range early this morning as temperatures cooled and some of the smoke aloft sunk closer to the surface. We'll probably see the AQHI stay there through the morning and then improve to a moderate risk this afternoon. With light wind in the forecast, it's unlikely that the smoke completely clear out of the area until early tonight or early Friday. The smoke modelling (which has been very accurate of late) has a significant improvement for Friday in the Edmonton area. However, northeastern Alberta will likely get a very smoky day Friday and may see some air quality warnings issued. Aside from the haze, we'll be Partly Cloudy through today with temperatures rising to around 23 or 24 C. There's an area of low pressure bringing showers to southern Alberta today and on the northern edge of that system, we may see a scattered shower or thunderstorm develop near the Edmonton region this afternoon or early this evening. It'll be very hit and miss and I think most of the city will probably get missed. Friday night and early Saturday morning have a much higher potential to bring some precipitation to the Edmonton area. We'll be partly cloudy and gusty through the day Friday. But, another low-pressure system moving in from the west will bring some showers and thunderstorms to western Alberta through the afternoon and evening hours Friday. As that system moves eastwards, it should push some showers OR periods of rain through the Edmonton region Friday night/early Saturday morning. It's still looking like we'll get a break from the rain for the late-morning and early afternoon hours Saturday (probably even a few glimpses of the sun breaking through the clouds). THEN...a chance of scattered showers for the evening hours Saturday. That should be a lot more hit and miss and the risk of showers Sunday looks fairly hit and miss as well. Bottom line: YES, we will very likely get some rain this weekend, and probably both days. BUT, it doesn't look like we'll see two full days of steady rain. Afternoon highs will be between 18 and 22 C (depending on whether we get afternoon precipitation and the timing). I've split the difference and gone with highs of 20 C for both Saturday and Sunday. Here's the forecast for Edmonton and area: Today - Partly cloudy with wildfire haze. Light wind. Slight risk of a late-afternoon shower or thunderstorm. High: 24 Tonight - Partly cloudy. 9pm: 20 Friday - Partly cloudy. Wind SE 20 gusting to 40. 60% chance of showers or periods of rain in the evening and overnight. Morning Low: 13 Afternoon High: 25 Saturday - 70% chance of showers or periods of rain early in the morning. Cloudy with a few sunny breaks through the day. 40% chance of a scattered shower late in the day. Morning Low: 14 Afternoon High: 20 Sunday - Mostly cloudy. 30% chance of a shower. Morning Low: 13 Afternoon High: 20 Monday - Mix of sun & cloud. 40% chance of shower. Morning Low: 12 Afternoon High: 20 Tuesday - Partly cloudy. Morning Low: 10 Afternoon High: 18

Toronto no longer under heat warning as special air quality statement ends
People enjoy activities on Lake Ontario overlooking the City of Toronto skyline at Jack Darling Park in Mississauga, Ont., on Wednesday, June 17, 2020. Toronto is getting a reprieve from the scorching temperatures and smoky conditions that have lingered in the city for the past several days. The special air quality statement that was previously issued for Toronto has now ended with the city's air quality index dropping to a 3, or 'low-risk,' on Thursday. Residual smoke from wildfires in northern Ontario and the Prairies previously prompted Environment Canada to issue an air quality warning for Toronto. At one point this week , Toronto had the second-worst air quality in the world, according to Swiss air quality tracker IQAir, While hot and humid weather will continue Thursday, a heat warning issued by the national weather agency last weekend has finally come to an end. Thursday will see a high of 29 C, feeling closer to 37 on Thursday but fresher air is expected to arrive overnight. Friday will bring sunshine and a cooler daytime high of 24 C. Saturday and Sunday will see the mercury rise to 24 C and 27 C on each day respectively.

Wildfire haze moves into Edmonton and could linger through Thursday
A view of the Edmonton skyline as the air quality index reaches dangerous levels on June 11, 2025. (Brandon Lynch/CTV News Edmonton) The Air Quality Health Index has increased to a 'moderate risk' for the Edmonton region as wildfire smoke has moved into the area from the southeast. The smoke originally pushed into southeast Alberta from Saskatchewan, but Wednesday's south eastly wind has drawn some of the smoke north toward Edmonton. You can see the reduced air quality stretching from Edmonton down to Medicine Hat on this map from early Wednesday afternoon. Air quality Air quality map. (Credit: We're expecting the haze to linger over Edmonton and area through to the end of the day Thursday. But, conditions should improve on Friday and early indications are that wildfire smoke shouldn't be an issue for the coming weekend.

How to read Environment Canada's air quality index and find out if you're at risk
Wildfire season is upon us once again, and smoke is reducing air quality through swaths of the country. Environment Canada suggests people check the Air Quality Health Index daily to determine how much time to spend outside. Here's how to interpret the index: HOW DO I FIND OUT MY LOCAL AIR QUALITY READING? Environment Canada's air quality index is at You can take a look at the ratings in communities across your province or territory. A rating of 1-3 is low risk, 4-6 is moderate risk, 7-10 is high risk and over 10 is very high risk. The risk designations can change regularly in the same community, Environment Canada says, so it's important to keep checking the air quality forecast. WHAT DO THE RISK RATINGS MEAN? Environment Canada, in consultation with Health Canada, has different recommendations for people especially at risk of suffering health problems when exposed to poor air quality compared to the general population. "At risk" people include those with respiratory issues such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, as well those with as heart disease. Infants, young children, pregnant people and elderly people are also considered at higher risk. The government agency lists the various health conditions that put you at higher risk at this website Here's how to interpret the Air Quality Health Index guidance: "Low risk" means everyone can safely be outdoors. "Moderate risk" means the general population doesn't need to change their usual outdoor activities unless they have symptoms such as coughing and throat irritation. But people at risk should "consider reducing or rescheduling strenuous activities outdoors." "High risk" means those at risk should reduce or reschedule strenuous activities outdoors. Children and seniors should "take it easy." The general population should consider reducing or rescheduling strenuous activities if they start coughing or their throats become irritated. "Very high risk" means everyone should reduce or reschedule strenuous activities. People at risk should avoid outdoor activities altogether.
