Hey there


I need to replace the filters on the return ducts of our ducted heat pump system. Can anyone advise me what shops (type and/or specific retailers) sell this stuff (other than the installers themselves - which aren't typically open weekends)?


And, do I need to buy the frame with the filter already fitted, or can (as I intended to) just buy the fabric and refit it in the existing frame? (It's just held in place via the soft plastic tubular stuff that keeps the mesh of a fly screen door in place.)


Edit: for reference, here's an image of a very similar (potentially identical) return duct to the ones we have installed.



Thanks for any advice.

They can sometimes be washed under the shower with a little liquid soap

Do they actually need replacing or just washing? The filter media shuld be a washable media so you can just spray on a cleaner (use something like spray and wipe, nothing too agressive) then hose them clean. Or put them in the bath or shower. Let them dry in the sun and put them back in. They should last for a few years before they need to be replaced.


Do the filters have a wire surround with the filter media stitched on or do they have a plastic or aluminume frame? You just need to know the overall dimension and find a filter supplier. Try Filters Direct, Shamon Air & Filtration (SAFE), filtercorp.

I reread your post and yes you can replace the media in the frames you have. Which town / city you are in? You could drop your frames into a filter company and they will replace it.


The other option is to contact the company that put the system in and they would be able to arrange new filters for you.

try holyoake or perfect air, holyoake are suppliers to installers and may not sell to the public, but perfect air could supply and install the replacement if needed providing you are in auckland, waikato, coromandel area

Thanks for all the feedback.

Yep, I washed them at the end of the winter season, but only when it got to the point I could hear a distinct change in the sound made by the unit. My bad for not realising this needed to be done regularly, but equally I know the installer never warned us to do this!

Given the comments they should last a few years I'm somewhat willing to leave it this year and check them at the end of the season. What should I be looking for in terms of knowing when they do need to be replaced?

More generally, what other basic maintenance should I be doing on any other parts of the system? I've cleaned around the outside unit and cleared out the various bungs on that, but is there anything else I can do to that, the inside unit and/or the ducting, to ideally avoid having to bring a company in to complete a service? (Or is that worth the cost?)

Thanks again.
