Hakutan Purifier ($95) Simplicity, nature, and function are fused into one with this beautiful all-natural charcoal air freshener. Charcoal has the natural ability to absorb odors and pollution. It can also be re-used for years with the simple maintenance of putting the block in the sun for a few hours once a month. Also, when you’re finally finished with your purifier, you can break it apart and mix it with soil to nurture your plants. This would be an excellent gift for any eco-minimalist (we know we’d love one). Chikuno Cube ($20) This is another charcoal freshener but much more affordably priced (yet still very stylish). The keen honeycomb design apparently increases its absorption power a “hundred fold”. ±0 Air Purifier ($340) Designed by master Japanese designer Naoto Fukasawa, this electric purifier will not only clean your air, it will feed you the gratification of owning a stellar piece of contemporary design history. Any Dieter Rams fan will instantly appreciate the beauty of clear, honest functionality in this all-around considered design. You can find more information on the ±0 line from their website. RabbitAir MinusA2 ($480) We’ve carefully examined this purifier in our Unplggd Test Lab and were fairly impressed with its performance. Some users will appreciate the option to ornament their machine with the optional vinyl stickers. The filtration system is impressive as well as its operating volume. If you’re looking for a high-powered purifier to remove those pesky allergens and the like, you may have found your match. Andrea Air Purifier ($125) Finally, we have this beautifully simple purifier which again harnesses the power of nature to clean and freshen our space. This minimalistic domed pot houses a small plant which is the muscle behind the operation. No filters are needed with this bad boy. All you need is some ol’ fashioned H2O to water the plant and electricity to power the fan which helps circulate the air.
