EDIT Brand new slim Tips inserts. I like them.
I’ve never changed the wax guard. I’ve only had the inserts a few days.
My provider took off the silicone cap and showed me the wax guard. However, I have nerve damage in both hands
How do I change the waxguards in my Phonak cshells? SLIM TIP? Inserts?
Here is a quick YouTube video which shows how to change the wax filter on a Phonak cShell.
Thanks. Great video.
My practitioner showed me how to remove the silicone jacket so the wax guard can be removed.
Looking at my two Paradise P90 R’s the opening on the silicone jacket looks smaller or isn’t centred on the wax guard.
Edit: thanks so much for showing me the video.
It’s incredible.
I think the silicone cap may not have to be removed if it’s put on right
I have nerve damage in each hand. It’s going to be hard for me to change wax guards. Or put the cap back on the cshells.
I figured it out
It’s a really tight fit. I had trouble. Took a couple of tries. The wax guard “stick” barely managed to pull the old wax guard out. It was better but not easy putting in a new wax guard.

Laughing at myself!
First waxguards change in my right cshells.
Clumsily done with the waxguards on a stick. See the hole on the silicone cap didn’t align with the wax guard. Made it. Took several tries. Thought I learned it all.
NOPE.
Did the second one.
Wax guard didn’t hook up. Came off the stick. But wasn’t in the hole. Destroyed it. Got it out. It fell on the floor. Cursing didn’t help me find it.
Meantime if pushed the receiver out of the cshells.
I have old eyes. And no sense of touch.
So I found more wax guards. Put one in the power receiver. Left the stick in. Put the silicone cap over it. Slid the silicone cap all the way down
The cshells are brand new. Thank heaven I left the right one intact. Because the first attempt on the left one I put the silicone on upside down. The pull wire was on the top, not the bottom.
My specialist had shown me to take the silicone cap off the cshells to change the wax guards.
Score. Me 3 out of 10
Cshells. A miracle. I can hear.
It’s taken over 5 years, two pair of Phonaks. 2 audiologists. And me.
Hallelujah! (I heard Leonard Cohen sing that at University. Live. ‘66? My date was the most beautiful young woman on campus) Back when hippies were real. Far Out!
I have worn Phonak’s cshell’s with my Marvels, Paradise, and now Infinio Sphere in both power and ultrapower configurations but I have never had or even seen any type of silicone cap on these shells. Could you upload a picture of the silicone caps you speak of. Maybe these silicone caps can be removed for good.
Dave, l am also confused. My cShells don’t have a silicone cap.
Thanks for answering.
Here’s what I know.
They were made from a mould.
Provider called them cshells. Made by Phonak
They have a silicone layer that comes off.
Take that off they won’t fit.
If it ain’t broke don’t change it.
I just need to know how to change the waxguards at the tip of each cshell
I hear much better with them on.
Darn silicone cap came off when I pushed the new wax guard on. If it happens again I’ll take a photo.
I found the process putting the silicone back on difficult. I was concerned that I had destroyed the cshell
I have nerve damage. No sense of touch. Both hands. If I do it again I shall take the waxguards out and not use them.
20 years of hearing aid use. I’m grateful that I can hear better with my new cshells

Edit @Neville
Darn wax guards!
Tried to add a photo. 
Incredible.
I’ll try again in a couple of days. I changed them last night.
The wax guard looks offset in the silicone rap. So I actually pushed the receiver out
Don’t know my own strength. 
Hope this works
EDIT: Thanks @Neville. Slim tips. Not cshells.
Sorry about the image. I can see it. Wish you could
Sorry DaveL, the image could not be downloaded. Perhaps it is too large. I gather your earmold is silicon. Mine are acrylic. There in may lay the difference. Good luck and sorry about your nerve damage. That is a bummer!
Nerve damage is ok. Just can’t feel hot. Cold. Sharp.
My moulds are perfect. I hear so much better. Everyone here who advocated for moulds had a difficult student to teach. You all did well
Edit: I’m told I have Slim Tips. Thanks @raylock1 and @Neville
Provider called them c-shells. I’ve been told here they are Slim Tips. I just know they were moulded perfectly and my hearing is much better.
And I know that I hate the wax guards. Reminiscent of the absolutely terrible Paradise P90
Understand, the HF3 filters on the slimtips are a little more complicated. I had to use those on my ActiveVent molds. I wasted a few wax filters before I got that down correctly.
Thank you!
However I received Cerustop wax guards.
Edit. So far.
If I push hard on the Cerustop stick the Power Receiver slides out of the silicone cap wrap.
That’s a plus
Then I remove and change the waxguard.
Leave the stick in the waxguard.
Slide the silicone cap down the stick. Remove the stick.
But. I can put the silicone on wrong. Upside down
That’s a pain in a tender spot.
They need to make hearing aids more carefully. Make them dufus proof.
Sorry. I’m ticked. Yet I can hear better! And that’s a miracle after 3-1/2 years of terrible stress with these and 2 years with previous hearing aids that almost got me killed at work.
Near miss 3 times on construction sites where I was just missed by equipment. I couldn’t hear behind me
Oops.
Absolutely awful Paradise P90 WAXGUARDS. That were replaced. Because at my age with my hands and eyes I’m having trouble replacing waxguards again.
I think I shall waste lots of waxguards over time. Doable. Not fun.
Summary. I am hearing much better now. But I’ve used these hearing aids for 3-1/2 years. Why so long
Is it possible to hold the slimtip so that one finger is over the back of the slimtip to keep the receiver from slipping out when you use the stick to secure the old wax filter and insert the new. Sorry, I could not figure out what was happening. I put your description, which was very complete, in chatCPT and it immediately described what was happening. Go figure 
I guess slipping the receiver out of the slimtip is part of the normal procedure ? In any event the replacements for Cerustops are pretty cheap on Amazon
There is a tool they have that helps hold the back of the receiver so it doesn’t push out. It has four sizes and a slot for the receiver wire. Fits right over the back end of the receiver and lets you push without worrying about pushing it out.

My hat is off to you. @raylock1 !
You have been so kind and helpful. Thank you!
Woke up this morning at 3:00 am and couldn’t sleep. I have a school under construction and it’s a tough one. I have a school in use on the same property. The old school has 350 kids. The new one will have 650. I’m grateful for the work. It’ll be used for 50 years. The old one was built in ‘78
Feeling old and frustrated.
