- Convenience and Self-care Are Becoming More Important: The broader allergy market is seeing renewed growth, with global allergy and respiratory OTC sales increasing 3.0% in the year to Q2 2025. IQVIA also highlights faster-acting products, combination nasal sprays, and Rx-to-OTC developments as important category trends.
Overall, the market is moving toward preventive, convenient, targeted, and evidence-supported allergy management. The strongest opportunities are likely to be around nasal delivery, natural/non-chemical formulations, personalized solutions, and technologies that reduce exposure to airborne allergens.
Recent Developments in the Allergen Blocker Market
The allergen blocker market is transforming from a focus on household allergen prevention to integrated allergen control in various market domains, including healthcare, air, textiles and other consumer products. The market expansion gained further momentum in 2025-2027, with product innovations and focused go-to-market strategies to target high-risk environments. Like the market shift, the focus of Lucintel's clientele also transitioned to demand for protection with clear and demonstrable evidence.
- Easier Access To Epinephrine: Positive results from Phase 3 clinical trials for neffy, announced by ARS Pharmaceuticals in February 2025, created a more convenient and faster way to administer epinephrine for allergic reactions. With wider access to emergency epinephrine, the consumer preference for products offering relief from allergic reactions and other conditions is expected to increase.
- Allergy Pill and School Policy: The U.S. Food and Drug Administration (FDA) approved, in January 2025, the expansion of the label of Xolair to include food allergy prevention in children 1 year and older. Schools and other institutions may purchase and implement preventive measures, in combination with pharmaceutical interventions, to address allergic conditions.
- Advanced Air Filtration: Launch of a formaldehyde air purifier by Dyson in March 2025, with a claim of removing the chemical from a 10-meter cube of air, demonstrates one of the many advances in air filtration. Other products may integrally sense and monitoring the quality of air in the space.
- Allergen Barrier Technology in Textiles: HeiQ reported in May 2025 the development of textile technologies to block dust mite and pet allergens. The company expects growth in this area and is currently collaborating with mattress and furniture manufacturers. Allergen barrier technologies will be included in regular mattress and upholstery construction.
- Regulatory Changes in The EU: The European Commission retained its ban in April 2025 on the use of several fragrance allergens. Cosmetic manufacturers must disclose 80 additional fragrance allergens. Because of these regulation changes, the personal care product industry will have to reformulate its products, increasing the demand for fragrance and cosmetics with low-allergen barriers.
Demand for low-allergen and personal care products is increasing and will continue to grow. Different barriers and filters will need to be validated. Competition among filtration and textile companies will be in validated performance instead of "allergy-friendly" claims. The market will be dominated by the companies that provide validated barriers in combination with widespread product availability.
Strategic Growth Opportunities in the Allergen Blocker Market
Allergen blocker markets are poised for growth due to increasing enforcement of food safety regulations, greater consumer awareness, and preference for "clean label" foods and beverages, approximately between the years 2024 to 2026. Lucintel's market intelligence suggests that the request for allergen blocking technologies will increase due to the growing burden on manufactures for clarification and disclosure of allergen containing ingredients, complex supply chains, and at risk product recalls.
- Barriers for Packaging: Barriers for packaging can be designed to block allergen migration. Premium pricing is justified for allergens barriers. Allergen barriers will be adopted by processors as demand increases.
- Pharmaceuticals & Dietary Supplements: Allergen barriers can be integrated in dietary supplements and medical food products. FDA maintained the 9 allergen categories for mandatory labelling. Allergens barriers will be valued by the pharmaceutical and dietary supplement industries.
- Digital Allergen Testing: Allergen barriers can be integrated in packaging and labelled products. Allergen barriers will be integrated with sensors and machine vision. The FDA's Food Safety Modernization Act of 2009 requires the food industry to maintain records for 24 hours. The act increases the focus on record keeping and allergen recalls.
- Recyclable Protective Barriers: Fiber-based and mono-material formats may let packaging manufacturers integrate allergen barriers and positively impact their sustainability records. The EU Packaging and Packaging Waste Regulation started its application on February 2025. Barrier performance will encourage brand owners to source packaging materials.
- Customization for Growing Markets: Formulating for and producing in smaller amounts may give packaging manufacturers opportunities in Latin America, the Middle East and elsewhere in the next few years. In 2025, the Codex Alimentarius Commission prioritized nine of its allergens. Suppliers wishing to pursue processors in these markets would benefit from Regulatory and Product compliance expertise.
While barrier claims would help packaging manufacturers capture more market space in the short-term, barriers with performance tests would gain more trust in the long-term. Packaging formats that incorporate allergen barriers help food manufacturers protect their products from liability while helping them to address stricter government disclosure standards and fit within the constraints of existing production and processing infrastructure.
Allergen Blocker Market Drivers and Challenges
The market is expected to grow due to greater understanding of allergies, advancement in barrier technologies, and increasing requirements for clearer product labelling. The market will also benefit from increased focus on sustainability. Additionally, as more people gain access to the healthcare system, it is expected that market demand will grow. Current trends have supported Lucintel's belief that market growth will be positively impacted by an emphasis on technology integration and regulation. However, there are challenges such as high costs associated with research and development, and uncertainty regarding the performance of allergen blocking technologies. The market is expected to experience significant growth in the coming years, especially if current competitors are unable to fulfill customer value requirements.
The factors responsible for driving this market include:
- Higher Awareness of Allergies: With increased diagnosis of allergies including food and respiratory allergies, there is more focus on the use of preventive measures. The Allergenic Products Defense Rule, issued by the U.S Food and Drug Administration in January 2025, continued the recognition of 9 major food allergens. Other preventive measures, like the use of barrier and protective products, are expected to increase in the coming years. It is expected that there will be an increased awareness and preventive measures taken by the families of vulnerable people.
- Advances in Technology: Continued advances in science and technology will enhance the filters used to capture allergens. In March 2025, most of the ongoing research focused on improving indoor air quality and air filters to capture very small particles including allergens. Advances in technology will reduce the thickness of the barriers, reduce the time of contact with the barrier, and ultimately improve the quality of the barriers.
- Regulatory Support: More stringent requirements in food allergen labelling, sanitation and cross-contamination, and indoor air quality are driving companies to invest in pre-emptive measures. In 2025, regulations in major markets required disclosure of 9 of the most common food allergens in the U.S. and 14 groups of allergens in the E.U. Lastly, throughout the next 3-5 years, greater demand for validation of blocker technologies, contamination controls, and process monitoring will increase, especially with more stringent enforcement and evaluation. Having traceability and providing validation of compliance will help suppliers in the food and beverage industry. Regulatory harmonization will benefit food and beverage procurement by reducing process and supply chain risks. It will also allow greater integration with other vertical markets (i.e. healthcare, public services).
- Sustainability and Product Innovation: It is projected that in the coming years, the focus in the consumer-packaged goods market will be on the circular economy, reducing product/packaging size, and using safer/fewer toxic materials. In 2025, a number of large consumer packaged goods companies committed to reducing the weight and increasing the recyclability of their packaging. All of these trends will increase the use of plant-based and bio-degradable materials, adhesives, and sealants. Other innovation will increase the functionality of a product by incorporating, for example, allergen blockers and/or odour/moisture/pathogen controls.
- Improved Manufacturing: Reductions in unit costs and increased assurance of supply are outcomes from improvements in automation, standardization, and flexibility in formulation and production. In June 2025, manufacturers of RPPs and similar products further automated quality control processes to inspect 100% of a given product batch. In the next 3 to 5 years, anticipate further decreases in unit costs of allergen blockade products, thereby increasing accessibility by small businesses and the health and education sectors, and by families in developmental markets.
The factors responsible for driving this market include:
- Challenges in Development: Continuous challenges in the validation of performance against the blocking of different allergen types increases costs. In July 2025, companies were required to perform testing against multiple exposure scenarios, including 14 of the internationally defined allergen groups. Higher testing and research costs may constrain product launch schedules of small-to-medium suppliers and increase launch schedule constraint of large suppliers. Small suppliers may be challenged to meet performance and blocking assurances against allergen types in product claims related to health and protection, and may increase the risk of adverse regulatory outcomes.
- Variability and Lack of Definitive Evaluation Criteria: Unlike regulated allergen controls, comparison of the performance of allergen-blocking products is difficult due to a variety of factors including the country and region of evaluation, the specific application, and the route of consumer exposure. As of August 2025, buyers report many markets where products claimed allocation of the nine U.S. major allergens, but performance evaluations were made using different, if any, performance testing criteria. During the next three to five years, performance assessment criteria are expected to be the basis of certification and labelling. The criteria, along with other factors, will unnecessarily slow the purchase and import of allergen-blocking products and increase their costs.
- Price and Availability of Raw Materials: The raw materials, including specialty polymers, filtration fibers, active ingredients, test services and compliant product and packaging closures, are expensive and subject to supply disruptions. As of September 2025, raw material and specialty product inputs and compliant product closures remained very limited. Manufacturers expected further price increases of 5 percent or greater in the raw materials and specialty inputs. Of the three-to-five-year outlook, manufacturers expected continued constraints in the markets and institutions most in need of products controlled for major allergens.
The awareness of food allergens and the need for solutions is increasing. Because of this, the allergen blocker market is expected to grow. More advanced technologies and greater focus on sustainability will improve the protection offered by and the impacts of blockers on the environment. As costs to manufacture blockers decline, they will become more affordable. There will, however, be limitations on the adoption of blockers due to validation costs not being outweighed by benefits, inconsistent standards, and supplies, among others. Allergen blockers will be successful if they are closely integrated into customers' everyday lives. In the next several years, the most successful companies will be able to integrate blockers into various uses in customers' homes, at work, and on the go, at an affordable price while still being effective.
