How to choose the right domes
Match the size
Domes are sized in millimetres (typically 6–12 mm). Use the same size your audiologist fitted — too small whistles, too large feels tight.
Match the style
Open domes keep the ear canal ventilated, generally for mild to moderate loss; closed and power domes seal more sound in, generally for moderate loss or worse. Tulip and double-vent styles sit in between.
Replace every 2–3 months
Swap domes when they discolour, stiffen or tear. Fresh domes keep sound clean and prevent earwax reaching the receiver.
When to change your wax filters
Change every 4–8 weeks
Replace a wax guard as soon as sound becomes weak, muffled or cuts out — that usually means the filter is clogged, not the hearing aid failing.
Always fit a fresh guard
Use the removal tool to pull the old filter, then press in a new one. Never reuse a guard — it's the cheapest part protecting the most expensive one.
Keep spares on hand
Filters are the most common reason a hearing aid goes quiet. A spare pack in your kit means a 30-second fix instead of a clinic visit.
