501 Filter Retainers, Pack of 6

These always break on me after a few pre-filter changes, having a pack of six makes it nice to not worry if they break. Seem to be more durable that the ones I have bought in the past. Great buy.

It is refreshing to buy something that works as it was intended !! These are a great value for the money !

good

Just make sure you get the right size for your cartridge and pre filter.

They filter covers will fit over a 3m cartridge. They are extremely tight and difficult to get on and off, but they will work.

GREAT

I use these filter retainers when we go trailer camping, to filter out the fumes from campsites that aren't just cooking their dinners. They fit fine but you have to remove them from the cartridge to swap out the prefilters, and they crack and fall apart readily. I'd rather pay more for a set that I can use multiple times. I ended up having to tape the filters on when two sets broke in three days on the road.

If you need these, you probably need them ASAP. Next day is pretty good since I couldn't find them anywhere locally.

They work well and are a good price
