The Blue Signature™ fabric pre-filter is available in six colors inspired by Scandinavian nature and interiors. Nordic Fog is a soft, pale grey that pairs with light, neutral spaces. Blue-Grey offers a cooler, muted tone ideal for modern or minimalist rooms. Beige brings warmth to natural or wood-accented interiors. Taupe sits between grey and brown for versatile, earthy styling. Dark Green evokes Nordic forest tones for a bold organic accent. A sixth colorway rounds out the palette for further customization. Each pre-filter ships in one standard color with your Blue Signature™ unit; additional colors are sold separately for $24.99 each. The fabric is machine washable, making it easy to swap colors with the seasons or refresh your look without buying a new unit.
Each Blue Signature™ model comes with one pre-filter in its standard color. Additional colors are sold separately.
A clean pre-filter helps extend the life of the main filter by capturing large particles like dust and pet hair.
All Blueair fabric pre-filters are machine washable. Just toss it in on a gentle cycle and air dry.
Our intuitive design makes it easy - just slide or lift the fabric off the top half of the unit and slide on the fresh one in seconds.
No replacement is needed. The fabric pre-filter is fully machine washable - run it on a gentle cycle and air dry. Only the main HEPASilent™ filter requires periodic replacement, approximately every 6–12 months depending on usage and air quality.
The Blue Signature™ fabric pre-filter is available in 6 Scandinavian-inspired colors, including Nordic Fog (pale grey), dark blue-grey, beige, taupe, and dark green. Each Blue Signature™ unit ships with one standard-color pre-filter; additional colors are sold separately.
