Let’s say the neighbors directly across the hall from you decide to throw a high-decibel party and keep their door open the entire time, giving their guests more space to hang out and light up.

Then, the next day, after you’ve absorbed enough secondhand smoke to make you a cigarette fiend (and you’re a committed nonsmoker!), the same neighbors launch a post-party housecleaning offensive, again with their front door wide open. Clouds of noxious chemical cleaners, the toxic sort you’d never use, waft into your place, adding insult to injury. The weather is rainy, hot, and humid — and, for the piece de resistance, your high-strung German Shepherd decides to let loose a steaming puddle of pungent pee! What do you do?

You get yourself a Moso Natural Air Purifying Bag, that’s what.

At least that’s what I did, and by the next morning, my place smelled fine. Available in two sizes, the Moso Natural is a little linen pillow that packs an impressive purifying punch. Basically a charmingly low-tech dehumidifier, it’s made of high-density, super-porous bamboo charcoal that works amazingly well to neutralize odors. The smaller 200g size purifies 90 square feet of stinky space; the 500g size, 250 feet. Both last up to two years and may be “rejuvenated” by baking in direct sunlight (preferably outdoors) for one hour each month.

Place a Moso Natural bag in the car, in the closet, or anywhere odors, bacteria, pollutants, allergens, mold, mildew, or moisture might accumulate. It’s even got a handy grommet at one corner, for hanging high out of reach of prying canine jaws.

But even if Spot does take a bite out of the bag, the contents won’t harm her — the most that will happen is that she’ll have a sooty snout! And when the Moso reaches its two-year life expectancy, it still has a positive effect: Just cut it open and scatter the charcoal in your garden or potted plants, to enrich the soil.
