If you purchased a Levoit-branded Core or EverestAir air purifier and/or replacement filter with “True HEPA,” “HEPA,” and/or “H13” language in the United States between August 29, 2019 and August 4, 2023, you may be entitled to an award from a class action settlement. https://lapsettlement.com/ #Levoit #ClassActionSuit #AirPurifiers #AirQuality #Filtration #HEPA

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? #DIY #CorsiRosenthalBox #CorsiRosenthal #HVAC #HEPA #MERV #AirQuality #AirPurifier #AirFilter

⚠️ Si vous avez un purificateur d'air et que vous avez été concerné'e par des incendies, ou autres sources de pollution, c'est peut être le moment de changer les filtres. Si ça ressemble plus à celui du haut qu'à celui du bas... faut le changer 😬 #HEPA #Purificateur #Incendies#Feux
