Also good for home furnaces. 1-inch Filtrete 1900 (MERV-13) has a lower pressure drop than most MERV-8 filters due to its high density micro-pleats. It's a quality product, best 1" filter available.

A New Chapter It's wattle time here in country Victoria, and the bees are ecstatic! All that glorious yellow cheers up the middle of winter no end. It's such an optimistic color. I'm feeling optimistic, too, even though this month did not go as planned. That began, as disruptions so often do, with…

CO2 and PM2.5 monitoring helps us understand the quality of the air we're exposed to indoors and outdoors. They also inform us about the strategies to mitigate exposure, such as wearing an N95, running an air purifier, closing windows and doors, and using MERV13+ furnace filters. #cleantheair

I hadn't seen this before. This is pretty remarkable. Earth and Moon in one NASA photo. ht @astrokatie.com

Great to visit St Mary’s Primary School in Battersea today - one of the first schools to receive indoor air quality filters as part of my initiative to improve children’s health. More than 200 schools will be getting indoor air quality filters soon.

Some good news 🥳 The first phase of installing air filters in all London schools is underway. 🙏 Thank you to @london.gov.uk & all campaigners involved #cleanair is possible! More info 👇 www.london.gov.uk/media-centre...

The area burned in the Canadian 2025 fire season has hit 5 million ha. Third active fire season in a row that combined has burned 7% of the Canadian forest. Currently we have 346 fires out of control (192 monitored out of control (OC) and 154 OC that are being actioned) so expect the number to rise.

What a pleasure to see Paris, a city that has become the epicentre of cycling, the most child-friendly city, which is creating urban forests and transforming itself to tackle climate change. Thank you and well done @annehidalgo.bsky.social 💫🙏🏻💫

Starter packs can still be a really good thing when we’re trying to grow a community here, like the city-building and urbanism community. Use responsibly, but please consider creating and sharing your own.

POLARIS UPDATE: Apologies to everyone that have been waiting for some updates on this ambitious project, after having to completely re-tool our campaign we hope to be launching soon! Brain fog issues have been slowing me down but I'm feeling better!

What’s your favourite thing about Bluesky so far? Bonus points for things that many of us might not know yet.

Thread for those new to BlueSky. First of all, welcome. It feels like a safer space, doesn’t it? But also perhaps a bit disorienting initially? Here’s some tips for getting your bearings.

Can you add me to one of the packs?

I reiterate - once again - updated COVID vaccines are not available for Canadians at this date. It’s like the 3rd doses that they withheld all fall from the general population and finally gave in Jan. I wrote extensively about this and yet, here we are again. I’m beyond furious and simply sad.

For the first time ever, there are vaccines for 3 of the worst respiratory diseases we face in cold-and-flu season. But significant numbers of Americans aren't planning on getting them, a new survey suggests. www.statnews.com/2023/09/28/f...
