A clean filter is necessary for the function of your Puritan Bennett 540. If your ventilator is being used outdoors, check your filter every week. If it is used indoors, you only need to check it every month.

Warnings:

Do not operate the ventilator with a dirty filter, you need to replace it
If your ventilator is installed directly on a wheelchair, check it more often than recommended
