If you suffer with chronic respiratory conditions such as asthma and allergies, there are certain irritants that never go away. Here are 5 chronic indoor triggers you should know about and solutions to minimizing them in your life.

Household Dust — Regardless of how vigilant you about cleanliness, this irritant is here to stay. Made up of particles such as minute bits of paper, pet and human hair, dirt, pieces of fabric from household clothes and furnishings, the list can go on forever.

Unfortunately, daily living creates this irritant that is usually found in the air before it falls to the ground. The secret to getting it under control is to reduce the amount that falls to the ground by continuously filtering it out of the air.

Seasonal Pollen — The amount and duration of airborne pollen varies with climate. Depending on your location and weather, tree pollen can start as early as January and the last of the weed pollen (especially ragweed) can be around until the first frost, which in some places does not happen until the end of November or early December .

Regardless of how careful you are about limiting air exchange between indoors and out, a lot of it will still get in by attaching to packages, hair, pets, and just blowing in through open doors. Having a reliable and effective way of eliminating these spores is an effective way to keep these irritant levels low.

Dust Mites — These critters are mainly found in the bed, bedroom, and / or on pet bedding. They feed and are able to increase their numbers exponentially when there is dander (dead skin flakes) for them to eat.

Covering bedding with covers that are specifically designed to prevent the mites from making a home in your matrass and pillows is a proactive yet non-invasive way to cut their numbers. Washing your bedding at least once a week in water that is 140 Fahrenheit or hotter also kills them.

Try turning back the covers instead of making the bed right away. Sunlight kills them as well. This is the perfect excuse for not making your bed (right away).

Mold and Mildew Spores — These come in from outside all the time. And if you are sensitive to them the best way to lower the count indoors is to dry up the wet areas. Check under the kitchen and bathroom sinks, shower, and foundation to make sure that water is not leaking and creating areas that are constantly wet.

Wet areas are a magnet for these spores. And the more available the water source is the more spores you will have in your air. Once mold has started to grow, a professional should be consulted to remove it effectively.

Pet Dander — You probably think you're safe if you do not have a pet. But that's not true. If you are living in place where the former owners had warm-blooded animals there is a huge chance that there is still dander in your home.

You can also bring dander home from co-workers or school mates that have pets. When your coat, bags, lunch boxes come in contact with their, it's very easy for dander to hitch a ride to your home. And if the contact is daily, you are most likely being exposed to it daily.

Because all of the irritants mentioned above are particles, one of the best ways to effectively remove them is to use a high efficiency particle arresting (HEPA) filter to clear the air. This type of technology is what hospitals use to insure clean air.

Effectively removing these allergens can not only give you physical relief from allergies and asthma, but can go a long way towards emotional relief for you and your family as well.
