Blueair - Blue PURE 311 Auto Pre-Filter

Regular price
$13.99
Sale price
$13.99

Info: Tweed Pattern; in Several Colours

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 in more muted colours, in a tweed pattern.

Product Notes:

Related: The main replacement filters for the Blue Pure 311 Auto are also available.

These 311 Auto prefilters come in three colours and two shades of gray in a tweed or faux linen pattern, and can be swapped out quite quickly while you wait for a newly washed one to dry, or if you place it in a different room. These models include a Velcro-style fastener to hold any excess length of cord close to the machine.

Compatibility: These particular prefilters are designed only for the 311 Auto model, and not for the Standard (non-Auto) Blue 311, which is a slightly different size and has its own series of prefilters (in the same colours).

Images shown are representative, colours will vary with different display settings.

Cleaning and Replacement Instructions:

The Blue 311 Auto Prefilters 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.
