How do you clean the filters? I own two of the 90B. They have been superior cleaners, want a smaller unit

Only the prefilter, basically a fine plastic screen, can be washed. The other filters (HEPA , activated carbon) have to be replaced every 6-12 months.

We have two of the units and find that the filters cannot be cleaned and reused; instead, they must be replaced. It would be nice if re-usable/cleanable replacement filters were available.

Honestly, I have never cleaned mine. They do get pretty nasty but that is normal and has happened on all of the canister filters I have owned. As long as they don't get clogged and effect the flow of water I don't worry about it. My water is crystal clear. My suggestion is to either buy new hoses, any hardware store such as home depot carries plastic hose in various sizes that you can cut to fit, spray them out with water pressure or use a long pipe cleaner brush. I hope this helps some.

The filter that comes with the unit is cleanable and reusable. Just clean the filter with a spray nozzle on a garden hose. Bon chance.

I use my vacuum to clean it, but my experience with these types of filters is to hand wash them in warm water and mild dish detergent. Just using your fingers. Inevitably the filter will degrade, so try not to wash them more than once a year. Also, these replacement filters are compatible with the BCL180W vacuum according to this web site: http://www.acetoolonline.com/Makita-451208-3-Pre-Filter-for-BCL180W-Vacuum-p/mak-451208-3.htm

I've found that vacuuming the filter and cleaning extends the life of the filter, buy you'll eventually have to replace the filter

In my opinion the filter does get dirty fairly quickly...I try to use a brush and get most of the stuff off of it myself rather than replacing every couple months.

Cool thanks! I have decided to order it. Just got it today! Excited to use it. Wondering where to get the filters for the glass attachments. Have to figure that out later. I know they last a while. So that will be figured out later I guess.

It's probably a dirty filter. You can wash and dry them or buy a new ones for about $12 each (pre-canister and HEPA). Made a world of difference when I cleaned mine--wondered why it ran like doo-doo after 10 years since they're supposed to never lose suction. Apparently they aren't miracle machines--you do need to clean/replace the filters occasionally.

I have not cleaned the black filters. Sorry, I can't be of assistance on this.

Does anybody have the instructions on how to clean this unit? I lost the box with the instructions in it... Thanks in advance

Mine did this too. I bought a whole new one instead of filters. It's only a few bucks more and you dont have to mess with the filter even if its a little wasteful.

Dear Sharon, When I did locate the filters last year, I found that they cost almost as much as a new unit, so I bought a new one. Really hard to throw away something that works; built in obsolescence to the max. And I suppose I will do it again next year.

Ther are probably different options, but I've not found them. Even at $90, getting the full set of filters is only a quarter a day. I just replaced mine after about a year, and the unit is working a lot more efficiently. I did find that if you run a hand vac over the odor sensor, it works better too.

I just cleaned mine actually...I just took it apart entirely and hand washed it like any other bottle...make sure u don't wash the filter though...that was just how I did it!!

Is this the first time you've used the unit? If so, I wonder if you didn't install it correctly...? On the other hand, if you've been using the filter for some time, it probably needs to be cleaned. Remove the filter, let it dry, then scrub with sandpaper, rinse in plain water, then re-install. At least, that's what I do when the filter stops working. Eventually, I need to buy a new filter.

It sounds as if you need to clean the filter. This vacuum is sop powerful for such A small appliance. I need to clean the filter very well after each use. I also put this filter in the washing machine about once a month and it comes out looking like a new filter. So, try emptying the filter more often.

I don't use mine all that much, but I haven't had to replace the filter yet. I do clean it after each use, but that's easy enough to do.
