Happy New Year! And especially “Happy No Pollen” for almost the entire United States! January is a rare month where there is no noticeably measurable pollen in the air from east to west coast (sorry Hawaii). Since the air is clear now is a good time to review the common pollen sources that will be here sooner than you think. Let’s learn a little about each one:

While not a complete or detailed list of all the pollens that will be tickling your nose this year, now you know a little about each one. Of course the cold and flu season is still going strong, so you aren’t totally free from sneezing and tissues. To keep those pollens, pathogens, dust and other nasty airborne things at bay this year you need an Intellipure portable air purifier. Intellipure's DFS technology uses electronically enhanced filtration to attract and capture ultrafine particles (99.97% filtration down to 0.3 microns). Simply choose an Intellipure portable air purifier for healthy home indoor air quality this new year.

Too Cold For Mold?

Many people think mold dies in winter, but that isn't quite true. In reality mold actually goes dormant until warmer weather arrives. Just being cold doesn’t make mold go away either, as mold spores have no problem causing an allergy attack in the winter. Mold can even grow indoors during winter! Our homes are warm and condensation can make for plentiful moisture in the wrong places. Add to it unpredictable winter weather like snow, sleet and rain that can create even more moisture (and make mold happier). Some types of mold like the cold and can grow on wet stuff like carpets or insulation. So remember mold spores are always around just waiting for an opportunity to grow. That’s why it's important to keep things dry and well ventilated inside to prevent mold from taking over.
