Famed maker of awesome Takara Tomy's latest bundle of cool is a super cute air filter for babies. It's outfitted with an antibacterial filter and Sharp's "decontamination ion" purification tech (my AC in Japan actually had this too) so your offspring don't inhale all the nasty, germ-y stuff floating around your house. It's about $150 (17,640 yen), so it's kind of pricey, but it's smaller (115x80x140mm) and definitely packs in more cute per square inch than most air filters. [Fuji Sankei via Tokyo Mango]
In medical school immunology we learned that exposure to normal household germs is how your body builds its immunity... I understand keeping excessive germ levels at bay, but keeping normal amounts away from a baby could actually end up being harmful. Playing in dirt, eating things that fall on the ground ect... I did them all and never get sick.
