HF4 earwax protection filters for hearing aids: block the wax and protect the hearing aid.
✅ HF4 hearing aid filters are water and oil resistant, which can prevent ear wax, dust and other foreign matter from blocking the speaker.
✅ Our HF4 filters are compatible with most brands of hearing aids on the market.
✅ They are easy to install, to ensure that the elderly or other groups can use the hearing aids effectively and simply.
✅ They are made of high-quality materials to ensure long-term durability: replacing the hearing aid filters should be done periodically (between 1 and 3 months, depending on the hours of use of the hearing aids and the amount of earwax that accumulates in the ear canal of the user).
