Written I don't know that there is a specific dehumidifier that would make a dust mite allergy better.  Dust mite allergies are from a reaction to dust mites, their old shells and their waste products.  To eliminate dust mites, remove their food source - dead skin cells.  Make sure your pillow is newer and wash it a few times a year.  Use a good pillowcase.  Make sure your mattress is not too old and use a good mattress pad and wash it often.  Use the vacuum attachment across the top of your mattress a few times a year.  Keep your bedroom clean and sweep under the mattress frequently.  Perhaps some sort of air filtration unit can help to cleanse the air in your room, as opposed to a dehumidifier.  Reply if you have more questions, or visit my blog for more dust mite info. Written Best dehumidifier to use at home for a dust mite allergy is any which will be able to maintain humidity levels below 50%.According to American College of Allergy, Asthma & Immunology dust mites die when the humidity falls below 50%.

But when humidity falls below 50% some people start feeling uncomfortable.You might consider other means of getting rid of dust mites.Asthma and allergies are the most common chronic illnesses for kids in the U.S. and attacks are often triggered by indoor air allergens, such as mold, dust, animal dander, and chemicals in everyday products. If your kids have allergies or asthma, then follow these easy steps to reduce indoor air pollution in your home: • Ventilation is crucial. “The building of tightly-sealed houses over the last two decades has made it much easier for moisture and dust to collect in homes,” Harvard professor Dr. Douglas Dockery notes. Many vapors trapped indoors, from perfumes and air fresheners to formaldehyde from particleboard, irritate asthmatics. When it’s fresh or even cold outside, keep windows open a crack to circulate air. On hot days, close windows and use air conditioners to ventilate and filter out smog. • Don’t harbor dust mites. Microscopic dust mites and their droppings are a potent allergen and asthma trigger.

One of the best ways to limit the amount of dust mites in your homes are to encase mattresses with impermeable covers (just be sure they’re PVC-free). • Eradicate cockroaches and keep clutter to a minimum. Piles of dirty clothes are an ideal environment for mildew, mold, and mites; blue air purifiers canadapiles of paper attract cockroaches. top allergies air purifierKeep things clean to keep these offenders away.dvd lens cleaning software • Maintain humidity below 50 percent. Dehumidifying is enormously important, as many asthmatics are highly allergic to mildew and molds. This can be measured with a hygrometer purchased at a hardware store. Droplets of water (condensation) on windows, walls or pipes are a sign of humidity.

• Minimize pet dander. Vacuum using a machine with a HEPA filter, dust frequently, wash drapes and rugs regularly, wash bedding weekly, and – for good measure – make at least one room a “pet-free” zone so your child has a reprieve. Of course, if anyone in your home is allergic to animals, you should reconsider having one at all. • Keep asthmatics away from gas stoves. Open the oven door and you get a blast of nitrogen dioxide (NO2). Your asthmatic child should not sit in the kitchen doing homework if the oven is being used. Make sure that stoves are well-ventilated, too. • Buy safer products. Everything you bring into your home impacts your indoor air quality. Choose unscented products as much as possible. Let anything with a “new smell” air out in a well-ventilated space or outdoors. And, watch for reactions even from natural products (essential oils can trigger attacks, too). • Try air cleaning and purifying machines. Consumer Reports says a good air cleaner can help those allergic to dust and mold spores, citing the fan/filter models as most effective in removing airborne dust.

The machine will help most in the asthmatic kid’s bedroom; but keep it at least six feet from the bed (it creates draft), and don’t place on carpet (it can kick up dust). But air cleaners & purifiers “only help if you’ve gotten rid of the risk factors first, like dust mites, mold and danders,” Harvard School of Public Health associate professor Dr. Harriet Burge warns. Warning: many asthmatics experience irritation from the ozone type of air purifier.If you have allergies or asthma, a tiny creature living in your home could be making big problems for you. Although you can't see them, if you have allergies or asthma you may be feeling their effects only too well. They are dust mites, and they live in many homes throughout the world. Dust mites may be the most common cause of year-round allergy and asthma. About 20 million Americans have dust mite allergy. Dust mites are well adapted to most areas of the world—they are found on every continent except Antarctica . It may not be possible to rid your home entirely of these creatures, but there are ways in which you can lessen your allergic reactions to them.

What Is a Dust Mite? Too small to be seen with the naked eye, a dust mite measures only about one-quarter to one-third of amillimeter. Under a microscope, they can be seen as whitish bugs. Having eight rather than six legs, mites are technically not insects but arthropods, like spiders. Mites are primitive creatures that have no developed respiratory system and no eyes. They spend their lives moving about, eating, reproducing and eliminating waste products. A mite's life cycle consists of several stages, from egg to adult. A female may lay as many as 100 eggs in her lifetime. Depending on the species, it takes anywhere from 2 to 5 weeks for an adult mite to develop from an egg. Adults may live for 2 to 4 months. Dust mites thrive in temperatures of 68 to 77 degrees Faranheight and relative humidity levels of 70 percent to 80 percent. There are at least 13 species of mites, all of which are well adapted to the environment inside your home. They feed chiefly on the tiny flakes of human skin that people normally shed each day.

These flakes work their way deep into the inner layers of furniture, carpets, bedding and even stuffed toys. These are the places where mites thrive. An average adult person may shed up to 1.5 grams of skin in a day, this is enough to feed 1 million dust mites! What Is Dust Mite Allergy? Household dust is not a single substance but rather a mixture of many materials. Dust may contain tiny fibers shed from different kinds of fabric, as well as tiny particles of feathers, dander from pet dogs or cats, bacteria, food, plant and insect parts, and mold and fungus spores. It also contains many microscopic mites and their waste products. These waste products, not the mites themselves, are what cause allergic reactions. Dust mite waste contains a protein that is anallergen—a substance that provokes an allergic immune reaction—for many people. Throughout its life a single dust mite may produce as much as 200 times its body weight in waste. Most dust mites die when exposed to low humidity levels or extreme temperatures.

But they leave their waste behind, which continues to cause allergic reactions. In a warm, humid house, dust mites can easily survive year round. What Can I Do? Unless you live in Antarctica or in an extremely dry climate, there is probably no practical way to completely rid your home of dust mites. But you can take action to lessen their effects. Having dust mites doesn't mean that your house isn't clean. In most areas of the world, these creatures are in every house, no matter how immaculate. But it is true that keeping your home as free of dust as possible can lessen dust mite allergy. Studies show that more dust mites live in the bedroom than anywhere else in the home. So to attack the problem of dust mite allergy, the bedroom is the best place to start. Unfortunately, vacuuming is not enough to remove mites and mite waste. Up to 95 percent of mites may remain after vacuuming, because they live deep inside the stuffing of sofas, chairs, mattresses, pillows and carpeting.

The first and most important step to reduce dust mites is to cover mattresses and pillows in zippered dust-proof covers. These covers are made of a material with pores too small to let dust mites and their waste product through and are called allergen-impermeable. Plastic or vinyl covers are the least expensive but some people find them uncomfortable. Other fabric allergen impermeable covers can be purchased from allergy supply companies as well as many regular bedding stores. The next most important step is to wash the sheets and blankets weekly in hot water. Temperatures of at least 130 degrees F are needed to kill dust mite. Other desirable, but not as critical, steps are to rid the bedroom of all types of materials that mites love. Avoid having wall-to-wall carpeting, blinds, wool blankets, upholstered furniture, and down-filled covers and pillows in the bedroom. Keep pets out of this room as well. Windows should have roll-type shades for the windows instead of curtains;

if you do have curtains, be sure to wash them often. It is ideal for someone without dust mite allergy to do the cleaning of the bedroom. If this is not possible, wear a filtering mask when dusting or vacuuming. Many drug stores carry these items. Because dusting and vacuuming stir up dust, try to do these chores at a time of day when you can stay out of the bedroom for a while afterward. Special filters for vacuum cleaners can help to keep mites and mite waste from circulating back into the air. These filters can be bought from an allergy supply company or in some specialty vacuum stores. Other rooms in your house can be treated similarly to the bedroom. Avoid having wall-to-wall carpeting, if possible. If you do use carpeting, the type with a short, tight pile is less hospitable to mites than the loose-pile or shag type. Better still are washable throw rugs over regularly damp-mopped wood, linoleum or tiled floors. Wash rugs in hot water whenever possible. Cold water leaves up to 10 percent of mites behind.

Dry cleaning kills all mites and is also good for removing dust from fabrics. Reduce the humidity in your home to less than 50 percent by using a dehumidifier and/or air conditioner. If you have taken as many of these actions as practically possible and are still having allergic reactions to house dust mites, allergy shots may help. A dust mite extract can be formulated to boost your immune system's response specifically to dust mite allergen. Shots for this purpose have been shown to be very effective. Dust mites are probably impossible to avoid completely. Still, they don't have to make your life miserable. There are many ways you can change the environment inside your home to reduce the numbers of these unwanted "guests". Your doctor is an important resource in helping you to keep dust mite allergies under control. Talk to him or her about measures you can take, sources of more information and of allergy products, and whether immunizing shots may be right for you. Together you can prevail against the effects of house dust mites.
