Keeping your components Dust Free

I use air purifiers through out the house along with an merv 13 filter for the whole house fan. I dust my gear once a week and vacuum twice a week. Not only does the routine keep the gear clean on the inside but also in return gives my allergies a safe haven and that aides in great listening sessions.

I use a dust cover for my integrated amp.
Stan will also sew the logo on the cover.

My apartment cleaners use a feather duster and cloth every few weeks.... 

I’ve found using Swiffer sounds better than a feather duster in a direct A/B comparison. 

All those periodic cleaning won't block dust from getting inside the circuits, but good news is, the equipment should work regardless of dust.
