Return and Exchange Policy

Last Updated: July 22, 2026

As HEPA Alerji, we have been offering quality products and reliable service in the field of allergy and respiratory health for over 26 years. While prioritizing customer satisfaction, we act in accordance with the provisions of the current Law on the Protection of Consumers No. 6502 and the Regulation on Distance Contracts. The return, exchange, and warranty conditions on this page apply to anti-allergic mattress protectors, air purifiers, dehumidifiers, sprays, and detergent products.

When you have a return or exchange request, we kindly ask you to contact our customer service first. After your application is reviewed, the product's condition is evaluated, and you will be informed as soon as possible. For approved applications, the product must be sent back to us complete, along with its original packaging if any and all accessories.

In distance sales, consumers have the right of withdrawal within the scope of current legislation. However, exceptions stipulated in the relevant legislation may apply if products that are not suitable for resale due to hygiene reasons have their protective packaging opened, are used, or lose their suitability for resale. The return conditions of products are evaluated according to their nature and usage status.

Allerworks Anti-Allergic Mattress Protectors feature special barrier fabric technology tested in independent laboratories. Independent laboratory tests have shown that our products maintain their allergen barrier performance even after 50 washes. Based on these test results, a 10-Year Protective Performance Warranty is offered for our products under normal home use conditions. This warranty covers the allergen barrier performance of the product.

The product features 100 percent cotton fabric, a breathable structure, no synthetics, a protective barrier against dust mites and common indoor allergens, comfortable use, and long-lasting performance.

Product exchanges can be considered if the product has not been used, has not been washed, has not lost its hygienic property, is in a condition suitable for resale, or a wrong size may have been ordered in which case an exchange with the appropriate size or an alternative solution can be offered.

Returns are not accepted due to hygiene standards for used products, washed products, cut or torn products, punctured products, products damaged by the user, and products that cannot be resold due to hygiene reasons.

The 10-Year Protective Performance Warranty covers the allergen barrier performance of the product and manufacturing-related performance defects. Situations not covered by the warranty include cuts or tears, punctures, misuse, failure to follow washing instructions, chemical or physical damage, deformations caused by the user, and normal aesthetic wear and tear due to regular use.

Air purifiers and dehumidifiers sold by HEPA Alerji are covered by a 2-year manufacturer warranty. Manufacturing defects are repaired free of charge under warranty, or the product is replaced if deemed necessary. Situations outside the warranty scope include drops, impacts, liquid contact, unauthorized intervention, user error, and use contrary to the user manual. For returns, the right of withdrawal applies to these products within the scope of current consumer legislation, and returned products are expected to be complete, clean, and in a condition suitable for resale. Filters are hygienic and consumable items. If it is determined that a filter has been used, soiled, or consumed in a way that is not suitable for resale, the loss of value occurring within the framework of current legislation is evaluated, and the filter cost or resulting value loss can be deducted from the refund amount.

Due to hygiene and product safety reasons, returns are not accepted on opened spray and detergent products. In case of wrong product shipment or a manufacturing-related issue, our customer service will provide the necessary support.

Cases covered by HEPA Alerji include wrong product shipment, manufacturing defects, and repair/replacement operations under warranty. Cases borne by the customer include wrong size selection, operations outside the warranty scope, user-caused damages, and exchanges made upon customer request unless otherwise agreed.

Benefits include over 26 years of industry experience, solutions offered to thousands of customers, products tested in independent laboratories, 100 percent cotton breathable fabric technology, after-sales technical support, and reliable warranty service.
