I followed a suggestion made earlier by some to remove the air filter on my Oneida dust collector since it is installed outside. I can't tell if performance increased but the noise is definitely louder. It was bothersome at least to me from a distance of about 100 yds. My closest neighbor is probably another couple hundred yards away, which has me concerned. I don't want to be a nuisance. I'm wondering if there's some way to reduce the noise without the filter? As for any performance reduction I wasn't dissatisfied with the filter installed so that isn't as much of an issue as the noise is now.
