I keep reading about Corsi–Rosenthal boxes as DIY air purifiers that outperform all commercially available air purifiers.
You literally only duct-tape four HVAC filters together and slap any regular PC fan onto them.
US-Americans recommend the brand #Filtrete for MERV-rated HVAC filters, but in Europe that brand costs at least twice or thrice as much as in the USA.
Are there any equivalent affordable HVAC filters in Europe with a MERV rating of 8 or 13? Or do I simply have to swallow the additional cost because HVAC filters aren't as ubiquitous in Europe as they are in North America?

Hazardous Air Quality - “Everyone should stay indoors and reduce activity levels.”
The DC region has blown past the expected Code Red Air Quality warning for Friday, July 18. It was only red for about an hour before moving to the purple “Very Unhealthy” for everyone range. Now, it’s mostly in the maroon “Hazardous” for everyone range, which is the highest this scale goes up to. This is due to wildfire smoke from Canada. Good thing rain is in the forecast for tomorrow.
If you have an N95 mask, such as the 3M Aura (which fits about 80% of adults), it is a very good idea to wear it. Under these conditions, a half piece respirator is better if you have one and need to go outdoors. Most hardware stores should have them in stock if you don’t have one on hand.
Remember that smoke rises, so stay on the lowest floor while indoors if you can. The PM levels for my upstairs rooms are much higher than my lower ones. You can seal leaky windows with painters tape and plastic sheeting to create a “safe room” with HEPA air purifiers or make a CR Box (I reposted a tutorial yesterday).

Why isn't our government mandating (& providing funding for) improved ventilation in public buildings? Study showed with 2.4 changes of the air per hour, cases dropped by 40%. With 4 changes of air every hour, infections dropped by 66.7%; when replacing the air 6 times each hour, infections go down by 82.5%! We need this in theatres, restaurants, schools...
