Natural Algae Air Purifier

The Natural Algae Air Purifier is living technology that brings the power of the ocean indoors. It uses live spirulina (blue-green algae) to remove carbon dioxide and produce oxygen as efficiently as 25 houseplants. Replace the algae every 60 days and use the old water for fertilizer in your potted plants or garden. Recommended for rooms up to 120 sq. ft. Includes algae starter kit.
