Kenmore 78423: Any advice on how to clean the pleated filter?

Mon, 29 Aug 2022 01:17:45 -0700

It is impossible to find any information on this vacuum on the internet! I see that this Kenmore model (115.78423210) has been discontinued, but I need to clean the pleated filter since I cannot find any replacement parts on this discontinued vacuum.

I am wondering if the part with the pleated filter can be soaked in a cleaning solution, or not (something like white vinegar). I also lost the foam filter (black on one side, white on the other) which goes next to the pleated yellow filter. I am unsure if the pleated filter is a HEPA filter or not, since there is no online manual for this particular model.

Having lost the foam black and white filter, the pleated filter is getting everything stuck between the pleats. Taking a toothbrush to the filter and brushing the debris out is no longer effective.

Any advice on whether I can soak the pleated filter?...or suggestions for another efficient way to clean it out?

Also any suggestions as to if there is a foam filter that I can buy which is compatible with this vacuum? (I measured the plastic casing of the pleated filter to see what size foam filter it would need and I measured about 4.25" x 4.25")

Thanks in advance!

Kenmore 78423: Source of bin filters for the 115 series models?

Fri, 26 Dec 2025 11:09:41 -0700

I have one of these little vacuum cleaners, and it works a treat. But the bin filter needs replacing, and I have found it impossible to locate anything online to replace it. Every filter out there is for the 116 series; they are rectangular in shape and too large. The 115 series (this model) take a square filter about 4.25 or 4.5 inches on a side. If anyone has any idea where to find replacements, I would love to know.
