Q&A

joshuaw81 提问: Hi Thomas, just started one of your cannon kits earlier today and it’s already turning gray. Already a fan of your work! Two quick questions for you: 1- I received a foam/fiber square that is white on one side and light green on the other. I’m assuming this is packaging, and not part of the filter? 2- Are these HEPA filters washable? Many thanks!

 

Hi Joshua,

Good questions! We’re actually working on a pamphlet to go along with the cannon that will answer these two questions, so it’ll be clearer in the future! But here are the answers:

  1. What’s the pre-filter for?

1

The pre-filter goes behind the HEPA filter, and it catches the larger dust particles so that the HEPA will last longer. We don’t include pre-filters on the Original DIY because the fan isn’t as strong as the Cannon.

  1. Can I wash the HEPA?

Unfortunately, no. HEPAs are not washable. That’s one reason we try to keep our HEPAs as affordable as possible.
