Cat litter mix.
Many owners of furry pets are unaware that the fine dust that is generated when filling or cleaning the litter can cause respiratory irritation. Clay-based or scented litters are particularly hazardous, as they often contain chemical additives and synthetic fragrances. To reduce the risk of an allergic reaction, it’s best to choose dust-free, hypoallergenic litter—such as those made from corn, wood, or compressed cellulose. It’s also important to regularly clean the litter box with hot water and a neutral detergent, and to place it in a well-ventilated area, away from bedrooms and the kitchen.

Bathroom rugs.
Bathroom rugs are often seen as a cozy and practical accessory — they keep your feet warm and help prevent slips. However, few people realize that these rugs can harbor a host of allergens. Constant exposure to moisture and steam causes them to absorb and retain dampness, creating ideal conditions for mold, mildew, and dust mites — all of which can trigger allergic reactions, skin irritation, nasal congestion, and asthma flare-ups. Soft fabric rugs with rubber backing are especially risky, as the seam between the fabric and rubber often becomes a hidden hotspot for mold growth. It is best to choose mats made of natural, quick-drying materials, or replace them with hard versions, such as bamboo or silicone, which do not accumulate moisture. Also, do not leave the mat on the floor all the time — it is better to hang it up after each use so that it dries completely.

Books on shelves (old books).
If books are kept out in the open for a long time, especially in rooms with high humidity or poor ventilation, they are literally saturated with allergens that are easily released into the air with every touch or turn of the page. For individuals sensitive to dust or mold spores, even brief contact with such books can lead to watery eyes, sneezing, skin irritation, or worsening allergy symptoms. This is especially noticeable in autumn and winter, when the premises are less ventilated due to closed windows. Additional discomfort can also be caused by old printing ink, which decomposes over time and releases irritating compounds. To reduce the risk, regularly dust your bookshelves and gently clean the books themselves every few months using a dry cloth or a vacuum with a soft-brush attachment. If you have a large collection of older books, it’s best to store them in enclosed cabinets with a dry, controlled climate.

Microfiber cloths and sponges.
Microfibre cloths and kitchen sponges seem to be common cleaning tools, but due to the constant humidity and food residues, they become a favourable environment for the growth of bacteria, fungi and mould. Even if a sponge looks clean, microorganisms can accumulate inside and later transfer to dishes, countertops, and other surfaces. For people with sensitive skin or respiratory conditions, this can trigger allergic reactions, irritation, or asthma flare-ups. That’s why it’s recommended washing cloths and sponges after each use, dry them thoroughly, and replace them every month. It’s also helpful to disinfect them weekly—boiling is an effective method. Regular care of these small items not only helps maintain cleanliness but also protects your family’s health.

Dishes with cracks and scratches.
Dishes with cracks, chips, or deep scratches may seem like a minor issue most people ignore. However, such damage can pose a real health risk. Food residues, grease, and cleaning agents can get trapped in these micro-cracks, where they begin to break down and create a breeding ground for bacteria, mold, and fungi. During later use, these microorganisms can transfer to your food or drinks—and then into your body. This can lead to digestive issues, stomach lining irritation, or even allergic reactions, especially in people with sensitive immune systems. Old ceramic or porcelain dishes coated with glaze pose a separate danger, as over time the glaze may begin to release harmful substances like lead or cadmium. While this is often invisible to the eye, it can affect both the quality of your food and your daily safety. To avoid such risks, it’s best to replace any dishes that show cracks or chips. Regularly inspecting your kitchenware is a simple yet effective way to reduce the impact of hidden allergens and toxins in everyday life.
If you already experience allergic reactions or have chronic respiratory conditions such as asthma, it’s essential to be especially cautious. In addition to removing sources of irritation, it is crucial to follow your doctor’s recommendations and take prescribed medications on time — for example, treatments such as Asthafen, Montair, Prednisone, Aerocort Inhaler, or Asthalin. A comprehensive approach that combines eliminating household triggers with proper medical therapy can help effectively control symptoms and prevent complications.
