The Pollen.com website has introduced several new features for its users.

Pollen History provides you a 30-day allergy index history according to your zip code. You can use the chart to track the pollens in your area are increasing or decreasing over time. You can thus check if there is a correlation between your flare-ups and the pollen levels in your locality.

The Two-City Comparison Chart should be very useful for those traveling for business or holiday, or relocating. You can compare the pollen intensity in your area with that of another location for the next four days simply by typing in the two zip codes. A chart will pop up, displaying bar graphs showing the pollen severity levels in the two locations for each day.

Also new is the "Allergy Buyers Club", an online shop for a wide range of allergy relief and healthy home products, including air purifiers, dehumidifiers, water filters, furnace filters, vacuum cleaners and hypoallergenic bedding.
