@CRBoxKits What I really want is that modern, densely-pleated filter tech in a thicker 2"-4" filter. There's plenty of unused volume in my fandelier design that could be filled with that extra filter area. For now, Filtrete/Starkvind better options for availability/cost. cc @JimRosenthal4.

@CRBoxKits These 3M filters are high quality, durable and a good value. Costco has both the 14"x30" and 20"x30" sizes at a great price right now (4-pack for $45). Ikea Starkvind is an alternative filter format to build off of, if these aren't available.

@CRBoxKits 30"x20" filters in my current build, used almost everyday for over 5 months. A scrappy prototype literally made of cardboard and construction paper, yet one of the most beloved lamps in the house. But a bit too tall, getting 6" back will be a relief.

Working well as a lamp too. Casts a warm, diffuse light onto the table below.

About time to build a new #fandelier for my dining room. Planning to go back to the roots and use 30"x14" filters to give some headroom back to the table. This is the same size @CRBoxKits used in the initial tabletop design that inspired me last year.

Fresh #crbuild @robwiss mega-sandwich style. 2x @3m Filtrete 14x30, 12 (new record?) fans total, 6 Asiahorse s001 on top and 2x Matrix 360 3-fan units for the sides. 660cfm raw. 2 controllers for visual fx, overkill. Finally you can eat without worries 😄#crbox #corsirosenthalbox

Canadian air filter folks! Can you check the prices of the Ikea Uppatvind and Starkvind filters? Will they ship to you?. I'm seeing $5 and $15 rn, which would make them great values especially for DIY builds. CC @DavidElfstrom .

Calling air filter Twitter, Costco has the 4-pack of Merv-13 Filtretes on sale for $45 again. This is one of the most economical options out there for building DIY air filters.

Study in air quality monitoring for self-quarantine isolation in a room. A trade-off between CO2 level, virus aerosols in stale air and heavy outdoor particle pollution.

Luftqualitätsdilemma im Seuchenzimmer, Fenster zu und sehr schnell sehr hohe CO2 Werte im Raum, oder Fenster auf und ordentlich Feinstaub. Vielleicht steht der Wind ja schlecht und bläst die Abgase der Pelletsanlage in meine Richtung, normalerweise ist das nicht so hoch.

Inspiration for the balloon test: comparing a Lasko box fan CR-box to Honeywell HF-910. Good demo, but one note: it's not a perfect test. Fans behind filters often have a lot of centrifugal (sideways) airflow, which won't hold up a ballon well, if at all.

#CorsiRosenthalBox The heights at which similarly sized balloons are held aloft, ~21” and ~62”, show the difference in the amount of air moved by a lasko fan and a honeywell HF-910 (both fans on low).
