  • Blue Signature™ Pre-Filter Colors

    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.
