I need a new dust filter for a small ceramic heater. Pelonis model #Hc441W

They just pull off. Slip a wide blade screwdriver or a couple of blunt butter knives under the edge and lever towards you.

You can get parts direct from Pelonis Support.

I worked in maintenance for several years, and often found hard to find parts at Grainger.com. Sometimes they can be pricey. Here's a link to there fan section. Fan Blades and Propellers

I have spent the last 1 1/2 hours going thru several of my catalouges and called a couple of my old suppliers and I can find no source repacement disc. Sorry I could not help you this time.Thank you.

I would definitly try to give your heater a through cleaning before before giving up on it. Remove screws that hold back cover on and remove cover. There shoulb be a fiter directly behind it,remove it and give it a through cleaning. I don't know on the new ones if the filter is made of foam material,the older ones like mine are.It is safe to wash them in warm water and a little dish soap. Rinse fully and pat dry. Clean any lint,hair,dust or any other foreign material from fan motor. Blow it out with compressed air if you can. You can use a tooth brush to clean around motor shaft and air ports on motor. You can use a couple of drops of fine grade machine oil on motor shaft,such as 3 in 1 oil or WD-40. Wipe off excess. Lightly brush heating elements and reassemble. I hope this works for you. Thanks We had our first pelonis disc heater for twenty years.

Hello YES that was a fuse just doing its job.A new one will blow just the same.Get rid of that heater, as that is the (doomsday) fuse.

One of those small ceramic units is compact and would do the job for a truck camper. They have fans built in and are pretty quiet. They are cheap and don't take up valuable space. I would look in a BigLots or close out type store.
