It is impossible to allergy-proof your entire house, so you should focus on the bedroom.

1.   The windows and doors of the bedroom should be kept closed, so that the outdoor pollen doesn't get in.

2.   No pets should be allowed in the bedroom.  If you are allergic to the pet, it obviously should not be in the bedroom.  Even if you are not allergic to the pet, it brings in the outdoor pollen.

3.   The bedroom should have a HEPA room air filter.  This can be purchased locally, and should be kept running 24 hours a day.  Don't forget to change the filter regularly.

4.   In addition, you can place furnace filter material (or cheesecloth) inside the vents in the bedroom, and you can put a filter in your bedroom window, if you like to have it open.

5.   Your pillows, mattresses and box springs need to be covered with a zipped allergy-proof airtight cover.  These are available at large department stores.

6.   The bedroom should be cleaned, vacuumed and dusted every day.  All dust-collecting items should be removed from the bedroom and kept elsewhere.

In terms of the remainder of the house, the best advice is to put an air filter in your furnace, and keep the fan running all year-round.  A HEPA air filter is preferred for the furnace, but the electrostatic filters may be acceptable if the filter material is the type that can be cleaned or replaced every 3-4 months.  For the remainder of the house, good cleaning techniques are important, with frequent vacuuming and dusting.

If you are allergic to your pet, it is best not to have a pet at all.  We know this is a difficult issue, so it may be an adequate compromise if you keep the pet out of the house at all times.  After you have gotten the pet out of the house, it is important to clean the carpets with a steam-cleaning or soap method.
