Nose filters are simple devices that are designed to fit inside your nostrils. All air entering your nasal passages is forced to pass through the nasal filters thereby preventing a large quantity of very small-sized particles from entering your nose. One of the beauties of these filters is that they are essentially hidden from sight.
Nose filters are being successfully used to alleviate the symptoms of allergic rhinitis, that is, nasal inflammation caused by an allergic reaction to very small particles such as pollen, dust, and dander. These particles are in the air we breathe, and the use of a nose filter can dramatically reduce the allergic reaction (sneezes, itchy and runny nose, itchy throat, itchy and watery eyes) that affects so many sufferers.
Nose filters for allergies can be very effective, suggest two recent scientific studies
In recent years, two studies on the efficacy of nose filters to reduce the symptoms of hay fever have been done. The first, in 2005, was titled “The reduction of rhinitis symptoms by nasal filters during natural exposure to ragweed and grass pollen.” Subjects were asked to wear prototype nose filters for approximately two hours. The tests were run in fall among various fields of flowering grasses. One group of participants received active and a second group placebo nose filters. The results were revealing. Most of the subjects using active filters showed significant reductions in their symptoms after only 20 minutes.1
The second study, “Preventive effect of nasal filters on allergic rhinitis,” from 2015, was run over two days. Allergy symptoms in most of the trial subjects were reduced by 50% or more, and there was a dramatic lessening of drowsiness.2 Drowsiness is a fairly common side effect of rhinitis and also of antihistamines. According to Dr. Sigsgaard of Aarhus University, this reduction of drowsiness could turn out to be the most important benefit for some allergy sufferers.3
Extending the idea of protection against outdoor allergens to dust and pet allergies
Recently, various nose filters for allergy relief have come on the market. They extend the idea to protecting against dust mite and pet dander allergies as well. No studies have yet been done specifically regarding nasal filters and dust mites. However, a good number of consumers report that they experienced relief from their symptoms as well.
WoodKnows nasal filters
Particularly popular are the filters produced by WoodyKnows, an American company that has addressed the need for efficiency coupled with the cosmetic aesthetics involved in everyday use by employing thin, soft plastic. WoodyKnows nasal filters have been designed for easy breathability and involve either mechanical filtration to trap allergens or the electrostatic method, which is more effective.
They can be worn continually and are not easily dislodged by normal sneezing. Many people wear them even during sleep. What’s more, they are designed to fit different-shaped nostrils, and easily changeable filter inserts give up to three days continual use.
Two basic designs are offered for protection against allergens. The Ultra Breathable nasal filter design caters for pollen, pet hair, and dander. It uses a single layer filter and woven mesh (0.04mm). The Super Defense design caters for pollen, dust, mold, and germs. It uses an electrostatic filter with a thinner fiber layer. Its breathability is still very good. WoodyKnows also offers a third design for vehicle exhaust and second-hand smoke.
We recommend the first two nasal filter designs for allergies. All three are cheap and the frames can be reused:
If you suffer from pollen hay fever, or dust mite or pet dander allergies, WoodyKnows Nasal Filters might be what you have always been looking for. You need to suffer no longer. Breathe easily knowing that you are protected. Get yours now and be allergy free.
