Allergies can be very serious, and some suffer from such severe allergies that they need to carry an epi-pen with them at all times in case they should have an attack that could kill them. So it makes sense to be careful, even if you are not at that level. Pet allergies are very common, but sometimes a new home owner doesn’t realize that the previous owners had pets until after he or she moves in. This can lead to an unpleasant surprise when allergies surface. Unfortunately, there is no quick and easy fix to remove all traces of pet hair and dander that will trigger your allergies. A thorough cleaning should make the situation much better though. You should make sure to use a vacuum with a HEPA filter specifically made for dealing with the fine pet dander. Replacing filters in your HVAC system and other vents will also help lessen the effect of previous pets.
