I have a cleaning busness, & Im around many typs of dust,animal hair and out door gardening. For me to stay allergy free is a must.We also have a wood burner stove to heat w/ during the winter. Although we have completly remodled our home my children and I have allergy brake outs that confine us to home.I do not like being out of control of me.Alavert gave us back our time that is needed to live a more normal life. With 2 children in collage, 1 in high school & 1 chasing a 3yr.old & exspecting we can not aford to be without Alavert. Thank You for the coupons, we have many in our home that use Alavert.
