Do you still sell the Cannon? It does not appear to be for sale on your online shop.
I was thinking of buying xiaomi 3h but this looks promising, but i’m only worried if this is loud? how does this DIY compare to store bought purifiers in terms of noise?
Hi, live in Australia where we are unfortunately exposed to bush-fire smokes in this season.
Is it critical for the filter to be tightly applied against the outside rim of the canon, or will a few mm gaps between the filter and the canon in some places badly compromise the performance as it leaks unfiltered airflow?
My HEPA filter doesn’t have an outer frame and therefore flexes in places under the pressure of the fan.
The low-tech approach would seam to suggest that we aren’t after an airtight bond between the two. Are you able to confirm?
Cheers.
