In the fall of 2026, as temperatures drop below 15 degrees Celsius in the mornings and evenings, replacing bedding is not just a preparation for winter but an essential task for the health of those suffering from seasonal rhinitis. Simply improving the bedding environment, which is prone to the proliferation of allergens like dust mites and mold, can significantly alleviate rhinitis symptoms. This article covers everything from how to choose fall bedding for rhinitis sufferers, proper washing and care methods, to discount information valid as of September 2026.
During seasonal transitions, large temperature fluctuations and dry air can sensitize nasal membranes, making rhinitis symptoms prone to worsening. Furthermore, bedding that has absorbed moisture throughout the summer becomes a breeding ground for dust mites and bacteria. The sweat and dead skin cells shed by people during sleep provide ample sustenance for these organisms, and critically, the carcasses and feces of mites that proliferate deep within mattresses and duvets act as potent allergenic antigens. Therefore, changing bedding for the autumn season should go beyond simply taking out thicker duvets; it should be a process of removing allergens and creating a comfortable sleep environment.
Material selection is crucial for alleviating rhinitis. It's advisable to choose materials that generate less dust, prevent dust mite habitation, and are easy to wash.
| Material | Key Features | Pros | Cons & Considerations |
|---|---|---|---|
| High-Density Cotton | Fabric woven at high density (over 100 thread count) with fine lint removed by enzymes (bio-washing). | Less static electricity, so dust adheres less; excellent breathability and absorbency. Low skin irritation and good durability. | Regular cotton may generate dust, so be sure to check for 'high-density' and 'bio-washed' processing. |
| Modal | Eco-friendly regenerated fiber made from beech tree pulp. | Silky soft texture, excellent antibacterial properties (99.9% bacterial reduction rate). Low skin irritation. | 100% Modal can be expensive and difficult to wash. Polyester blend products may have reduced breathability. |
| Microfiber | Synthetic fiber woven from extremely fine threads, 1/100 the thickness of a human hair. Primarily used in 'allergy care' functional bedding. | Dense structure physically blocks dust mite penetration. Lightweight, excellent warmth, and easy to care for. | As a synthetic fiber, it's prone to static electricity and may have less sweat absorption or temperature regulation compared to cotton. |
| Wool | Natural crimped structure creates air pockets, providing excellent warmth and humidity control. | Blocks external air while releasing internal heat and moisture for comfort. Maintaining a pH level of 6 can help improve respiratory conditions. | Often difficult to machine wash, but 'washable wool' products have recently been released. Always check the label before washing. |
If you've acquired new fall bedding or are reusing existing bedding, it's crucial to follow the steps below for hygienic replacement.
Washing and Storing Summer Bedding Summer duvets have absorbed a lot of sweat and moisture, so they must be completely dried after washing before storage. Washing instructions by material are as follows:
Washing Fall Bedding and Bedding Covers Always wash stored fall bedding or newly purchased bedding before use. Dust mites die at high temperatures of 55-60 degrees Celsius or higher, so washing at the highest temperature the material allows is effective. Rather than the amount of detergent used, thorough rinsing to completely remove mite carcasses, feces, and detergent residue is more important.
Mattress and Pillow Care Simply changing duvets is not enough. Mattresses and pillows are key habitats for dust mites. Since these are difficult to wash, it's effective to use allergen-blocking waterproof covers or zippered full covers. Wash covers at high temperatures at least once every 2-3 weeks.

Q1. How often should duvets or pillows be replaced? A. While it varies depending on the material and care, it is generally hygienic to replace duvets every 2-3 years and pillows every 1-4 years. Polyester-filled pillows are recommended for replacement after 2-3 years, latex or memory foam after 3-4 years, and buckwheat material after 1-2 years of use. If the cushioning significantly decreases or odors persist even after washing, it's time for replacement.
Q2. Is it absolutely necessary to wash at 60 degrees Celsius or higher? I'm worried about damaging the fabric. A. To completely eradicate dust mites, high-temperature washing at 60 degrees Celsius or higher is the most effective method. However, materials vulnerable to heat may deform, so you must always check the product's care label before washing. If high-temperature washing is not possible for the material, a practical alternative is to use an anti-allergy cover and frequently wash only the cover at high temperatures.
Q3. Is 'Allergy Care' functional bedding truly effective? A. Yes, it is effective. Specifically, high-density microfiber (초극세사, ultra-fine fiber) fabrics woven with threads 1/100 the thickness of a human hair or less have extremely narrow gaps in their fiber structure, making it physically difficult for dust mites or fine dust to pass through. Therefore, it can provide significant help in blocking allergens.
