New - Coming Soon!

Like the other members of the Blue Pure family, Blueair Pure 311 Auto Air Purifiers have a fabric pre-filter around their entire base where the air filter resides, both for decorative reasons and to catch larger particles like dust and hair, to prevent the main filter from getting saturated too quickly. The ones for the new Auto machines come it more muted colours in a tweed pattern.

Product Notes:

area on back of Blue Pure Auto pre-filters to store excess power cord lengthThese 311 Auto prefilters come in three colours and two shades of gray, and can be swapped out quite quickly. They should be vacuumed with a brush attachment periodically (while still on the machine) to remove the dust and hairs they accumulate, and can also be taken off and washed in a washing machine. These models include a Velcro-style fastener to hold any excess length of cord close to the machine.
