Allergens and other indoor pollutants
Opening a window can improve
your health
MetPet.com Staff Writer
 Houses and cars today are so well insulated that indoor
pollution can actually be worse than what's outside. Chemicals on fabrics, cleaning
agents, pesticides, mold, dust, smoke, cooking fumes, dander, etc. can accumulate inside
the house and cause or aggravate allergic reactions in people and pets.
Here are some useful tips to make your home healthier for
everyone.
Open the windows
Provided there's no "spare the air" day in your area (i.e. when outdoor
pollution makes breathing the air hazardous to those susceptible to respiratory problems)
then open up windows and let the air circulate every day.
Before you open your windows please make sure you have
screens to prevent accidental falls by pets. Every spring in large cities
everywhere, cats are subject to "high rise" syndrome. They slip and fall
out of tall buildings with often tragic consequences.
You will need open windows on both sides of your house for
circulation. Otherwise, you can turn on a fan to help move the air. Central
air conditioning set on "fan only" is another option.
Clean air filters
Depending on your system and how dusty your house can become, you should clean or replace
air filters every six months. Some filters can be vacuumed and rinsed with a hose,
others need to be tossed and replaced with new ones. A good rule of thumb is to
check them once a month to see if there's buildup. At minimum, the change of seasons
(turning on the air conditioning or the furnace) is a good time for a checkup. Some filters do a
better job than others so inquire at your hardware store or home center for what's
new.
This is also a good time to vacuum vents. That strange
little round brush attachment for your vacuum helps you get between the slats.
Clean carpets
As much as we love them, thick wall-to-wall carpeting is a dust and dander magnet.
Fleas and dust mites, hair and dirt just love that luxuriant pile to hide in. If
you're considering replacing your flooring, a hard surface like wood, laminate, vinyl or
tile harbors fewer allergens. If you must have
softly carpeted floors, consider an industrial or office type carpeting with a
very short pile (1/2") and tightly woven fibers.
Another option, becoming more common, is to minimize dirt and
grime in the first place. Try leaving outdoor shoes in the front hall, replacing
them with slippers or indoor-only soft clogs. Place lightweight, washable
mats both inside and outside the door to catch as much dirt as possible.
You can even use lightweight, washable area rugs on top of the wall-to-wall
provided both the carpeting and the rugs are colorfast and won't bleed color
onto each other.
When choosing small rugs and mats, make sure
they're rated by the manufacturer as ok to wash in your washing machine.
If you need rubberized bottoms, consider getting a separate rubberized rug mesh.
Rubber and plastic non-skid bottoms tend to disintegrate in the wash over time.
Deep clean carpets once every six months to a year depending
on wear. If you use a flea-powder like boric acid, remember to replace it after
steam cleaning.
Clean pets
As much as 10% of the US population and 30% of asthma sufferers are allergic to
some parts of some animals. The most common pet related allergy is to dander
which consists of dead skin cells that fall off of pets on a regular basis. Saliva
in cats especially contains the Fel d1 protein which is a common cause of
allergic reactions. When cats groom themselves with their tongue which
they do often, the allergens are deposited on the skin and fur. As skin
cells are sloughed off or as the fur is petted the allergens are released into
the air or onto skin and clothing.
A regular washing program can help
reduce the amount of allergens considerably. If you roll your eyes at the
thought of trying to give your cat a bath, wash your hands after handling him
and keep him away from direct exposure to your face. Even wiping your cat
daily with a fresh, damp wash cloth may help reduce the number of allergens.
It's best to keep pets out of the bedrooms and definitely off
the bed to minimize exposure to allergens during sleep. If you want to
give them access to the bed to sleep on during the day, make sure to cover the
entire bed with a sheet that you remove at night.
Wear lighter clothing that can be
cleaned frequently
Studies show that lighter weight cotton clothing such as T-shirts hold fewer
dust mites and allergens than do heavier clothing such as wool sweaters.
Since allergens are everywhere, it's best to wash clothing, especially that worn
above the waist, before wearing it each time.
It's hard to believe but cat dander actually exists in
Antarctica although there are no cats there and, as far as we can tell, never
have been. The dander made it to the scientific research colony there on
the clothing (particularly the sweaters) of visitors!
Streamline your environment
Heavy drapes, lots of stuffed animals, excess cushions and overcrowding in general can
aggravate the situation. Twice a year, pack up everything you no longer use and
donate or dispose of it. Minimize dry flower arrangements, wreaths,
tapestries, open bowls of potpourri,
dust-collecting decorations, stacks of dusty books and excess plants.
If you have a choice, select miniblinds or plantation
shutters over fabric window coverings. If you want fabric coverings,
consider washable sheers or cafe curtains in order to minimize the amount of
fabric. Curtains actually act as filters, trapping dust and providing
homes for little critters as air moves in and out of the room.
Select furniture with exposed legs that are
easy to clean under. Consider leather, wood or vinyl furniture instead of
heavily upholstered pieces. Cover chairs and sofas with inexpensive slipcovers that can be
washed weekly. Flat bed sheets work well as inexpensive covers and are
easy to clean. Not only will you reduce allergens and pollutants, you'll have less
cleaning to do.
Pick up dust
Vacuum dusty places thoroughly several times a week. Then spray water,
water&vinegar solution or a cleaner such as Windex onto a paper towel and use it to pick up remaining
dust. Feather dusters and dry mops tend to just move dust from one place to another.
Clean and air out cars
If you travel on crowded commuter highways, you probably keep your windows
closed. Recent studies are now showing that air pollution inside
your car can be significantly worse than
what's outside your vehicle. If you park in your own garage, open the windows when
you get home to allow air to circulate. Periodically use your air
conditioning system to bring in fresh air rather than just recirculating
interior air.
Dander, dust mites, etc. from your home can be
tracked into your car via shoes and clothing. Vacuuming the carpets and
seats once a week is probably all you'll need to minimize most allergens and
pollutants. When buying a car, consider getting leather instead of cloth
seats and plastic or rubber mats instead of carpeted ones.
Smoke outside
Pets who live with smokers are subject to the same respiratory problems and cancers that
people are. As studies now show, the smoke from the tip of a cigarette is more
hazardous than what the smoker inhales. Just to be safe, it's best to smoke outside
away from your pets.
