RpR said:Wet/Dry vacs DO need filters, the better the filter the longer it will last and I have gone through three already -- big ones.
Check filter type before buying.

When the fill they lose suction, and the smaller they are the quicker they fill.
I had two small ones , both sat outside in the garage; the hose one one, after not being used for severl years, crumbled when I tried using it.

You will get what you pay for, less is not more.

My old wet/dry is on it's original filter...*maybe* it's second. It's a 5.5hp Craftsman that's probably 15-20 years old. It's been used a number of times for getting up water...and LOTS of heavy duty dry vacuuming. I've simply always removed the filter when vacuuming up water and it works fine. When I'm through I put the dry filter back in. From time to time I'll beat the dust and dirt out of the filter or take an air compressor to it.
