Recent studies show a direct link to dirty air and increased allergy problems. An allergy relief air purifier is only part of the solution these days, now you will have to pay close attention to all the air particles you breathe, and not just the allergens. Allergy specialists recommend monitoring allergen reports and pollution reports together to determine the severity of your possible symptoms. You can also use these reports in tandem to figure out what settings to set your allergy air filters to. Knowing both pollution and allergy counts are also helpful in determining things such as whether or not to burn wood in fireplaces or wood stoves, mow the lawn, or even clean the house. On days where both counts are bad, you should avoid all those activities.
