Do this step right before allergy season sets in. Start with porous items like old rags, newspapers, and clothes. Discard those that are out of use and clean the rest. Try to keep your surfaces clear and free of knickknacks and magazines that collect dust. The bedroom where you spend the most time is a room that you should air out and dust thoroughly since allergens like dust and mites tend to be concentrated in this room. Carpeting, curtains and upholstered furniture in the bedroom should be vacuumed with a HEPA filter. If you can, use blinds for the allergen season and swap out your carpeting for a throw rug which can be thrown in the washing machine frequently. Mop exposed floors daily so that your house stays dust-free.
Clear the air and seal the house
Get your house as well-ventilated as you can. Seal leaking ductwork to keep allergens outside the house. Then fit a HEPA (high-efficiency particulate air) filter into your air conditioning. This weeds out even more allergens. Set your thermostat at a humidity level of 50 percent. This magic setting knocks out mold (it will be too dry for it to grow) as well as dust and pollen (too moist for them to be stirred easily) with one fell swoop. Keep your windows closed in the early morning hours or if it’s too windy outside.
Set up a mudroom
If you have a mudroom, organize it so that clothes, jackets, footwear, and socks can be cleaned as soon as possible. If you don’t have a whole room, it’s easy enough to set up an area near the entrance of the house where you can take off jackets, shoes, and socks where pollen particles might have settled.
Scrub and air the bathroomYou should get into the habit of airing out a bathroom even when it isn’t allergy season. A damp steamy bathroom is a breeding ground for mold spores. Clean walls with a non-toxic cleaner and scrub off mold spots with a solution of water and bleach. Leave ventilation fans on for about 30 minutes after a bath so that steam can be directed outside.
Plant some non-allergenic plants, trees, and flowers in your yardAvoid planting trees like maple (male), birch and ash (male) in your yard. Instead, plant dogwood, double-flowered cherry, and magnolia. Non-allergen carrying flowers include astilbe, impatiens, hosta, scabiosa, columbine, and viola.
