When spring comes around allergy is a common problem because many plants produce pollen that triggers allergic reaction to people. In times like these people should protect themselves from these allergens. There are air filters in the market that you can install right in your house. Make sure that the air filter you buy has HAVC filter, these are high velocity filters unlike ordinary filter. The advantage of these filters is that it not only filter pollen, but it can also filter the smaller particles like mold spore, some germs or bacteria and dust. Just remember to buy from a trusted vendor that has been selling filters for years.
