Is the CT15 filter washable and reusable?
« on: February 14, 2021, 08:54 PM »
Picked up the CT15 and put it to a quick test. The manual does not have any info. on whether the filter element can be washed for reuse. Does anyone know if it can be cleaned with water jet like other HEPA filters?

Good question, had t considered that.  What are your impressions of the CT15 and what are you using it for?

I’m considering getting one for dedicated use for the Kapex.

I would not try this.

Clean it out with an other vac and a brush, and gently tap it against a wall, that's all you need.

I've had a few clogs lately because a paper bag tore in my old type Midi, and I got the filter completely clean and functional again without using any water.

The filter looks liks some sort of cardboard, not something I'd think is waterproof.

Correct.

In any case do not let a water jet near any microfilter. Even officially washable ones.

The water jet pressure can destroy the microstructure of the filter so it will no longer work /as intended/. You will end up with "clean" filter but end up breathing the dust. Your lungs doing the "filtering" instead.

Thanks Alex and Mino for the sound advice, and on how it should cleaned. A replacement filter element is pretty spendy ($94 Cdn).

Good question, had t considered that.  What are your impressions of the CT15 and what are you using it for?

I’m considering getting one for dedicated use for the Kapex.

This new extractor is intended for use with the DF500, PRO95 sanders and any other general dust collection duties (cleaning the workbench, say). Previously, they shared the use of a shop vac/Dust Deputy with the Kapex, which means I had to switch hoses all the time (36mm for the miter saw). My Kapex produces a lot of saw dust as I use it often, so the DD approach is a better approach in my case.

If you don't use the saw on a weekly basis or make lots and lots of cuts each time, the CT15 is a great-value choice. I did buy an extra pack of 5 bags ($48 Cdn?), and that should last for many years.

I find the CT15 comparable to the CT26 I previously owned in operation. Compared to the old CT26, the CT15 stores the cord in a lidded holder. Its dust bag collection design looks good, as explained here:



I took the opportunity to measure the noise levels, using a cheap sound level meter:

- Room sound pressure level: 45ish
- Max suction: 84ish
- Min suction: 75ish
- Fan box filtration (cfm: 2500; Merv 11 filter): 72ish

Thanks Chuck for the info. I don’t use the Kapex much, not even everyday or just a few cuts each day so it should work well. Also thanks for the db info.

Sorry to have hijacked the thread.

After evaluating several potential spots for the new extractor, I decided to place the CT15 next to my workbench. The extractor performed flawlessly in today's Domino operation (the project involves the milling of about 100 mortises).

The overhead hose previously used with the shop vac/dust deputy is now a surplus to requirement.  ;D
