Allergies What You Need to Know to Survive
Clean the Air
Keep windows closed and set the air conditioner to "re-circulate" to keep out pollens. Clean air filters frequently. Each filter has a MERV rating - which is a scale that tells you how good a filter is at removing allergens in your home. The highter the rating, the better off you are. Look for a mERV value of 11 - 12.
