Horsehair vs Synthetic Latex

Allergies:

Properly processed horsehair is considered hypoallergenic and suitable for most allergy sufferers. The manufacturing process involves washing in boiling water, then steaming at 284°F (140°C) at four times atmospheric pressure with high humidity. This thorough sanitization removes proteins, allergens, and bacteria that could trigger allergic reactions. Multiple manufacturers report they have not encountered customers experiencing allergies to properly processed horsehair. The material has earned NOMITE certification, indicating suitability for house dust mite allergy sufferers. However, individuals with specific horse protein allergies should test before purchasing. Always verify the horsehair has undergone proper high-temperature processing rather than simple washing.

Dust Mites:

Horsehair provides excellent resistance to dust mite colonization when properly processed. The high-temperature steaming process (284°F at four times atmospheric pressure) kills any existing mites and removes allergens. More importantly, horsehair's superior moisture-wicking properties create an inhospitable environment for dust mites, which require warm, humid conditions and human skin scales for survival. The constant air circulation and rapid moisture removal prevent the damp conditions dust mites need to thrive. Many horsehair products earn NOMITE certification, the anti-allergen standard indicating suitability for house dust mite allergy sufferers. This makes horsehair significantly better for dust mite allergies than organic materials like down, wool, or cotton which retain moisture and provide favorable habitats.

Chemical Concerns:

Minimal chemical concerns when purchasing from reputable manufacturers. Quality horsehair processing involves only water, steam, and high heat - no bleaching or chemical treatments. The entire sanitization process at high temperatures and pressure is completed without addition of foreign substances or synthetic chemicals. Look for OEKO-TEX Standard 100 certification ensuring horsehair has been tested and verified free from harmful chemicals and substances. No VOC off-gassing or synthetic processing. However, be cautious of very cheap horsehair products which may undergo inferior processing or use chemical treatments. Always verify the manufacturer uses proper steaming methods at 284°F+ temperatures.

Allergies:

Generally hypoallergenic and safe for most people including those with natural latex allergies. Synthetic latex (SBR) does not contain the proteins from Hevea brasiliensis rubber trees that trigger Type I latex allergies. However, some individuals may be sensitive to styrene, butadiene, or chemical additives used in manufacturing. Those with chemical sensitivities should look for CertiPUR-US certified foam. The dense cellular structure naturally resists dust mites, mold, and mildew better than fiberfill materials.

Dust Mites:

Excellent resistance to dust mites due to dense foam structure that prevents mite penetration and colonization. Scientific studies show latex foam materials (both natural and synthetic) harbor significantly fewer dust mites compared to traditional fiberfill materials. The solid foam construction provides no spaces for mites to burrow or food sources to sustain populations. However, dust mites can still colonize pillow covers, making washable protectors essential for allergy management.

Chemical Concerns:

Synthetic latex is petroleum-derived and may contain residual styrene, butadiene, and various chemical additives including vulcanizing agents, accelerators, and stabilizers. New pillows typically have chemical odor requiring 24-72 hours aeration in ventilated area. CertiPUR-US certification ensures foam meets standards for low VOC emissions (less than 0.5 ppm), no ozone depleters, no mercury/lead/heavy metals, and no prohibited phthalates. OEKO-TEX Standard 100 certification provides additional assurance of no harmful substances. Quality varies significantly between manufacturers.
