What Leo said!
Also when not using
put the respirator
in a Ziploc bag or sealed container
Once you open the filters package
They are constantly working

Absolutely keep them in a sealed container. Technically the charcoal is good for a few months depending on concentration of fumes. Back in the day making surfboards for a living when I lived in a respirator for hours a day I switched out 2-3X a month. The particulate filter once a month. I hope you're using a full face mask with the CV.

Pretty sure a pair of cartridges are good for about 8-10 hours of heavy concentrated use. In the sprayroom with a fan taking a good portion of the fumes away from you they will last longer.

I would think that you should change them at least weekly.

get yourself a supplied air system.

Chris,
What brand of supplied air system do you have? I am considering one.

I have a 3m versaflow system
very comfortable. also supplies coool air which is great in summer.
make sure you get a supply air hose which is made for supplied air not just a regular hose.

General rule of thumb is 40hrs of usage or one month for most respirators at high concentrations. An hour here and there spraying with a good exhaust system is not to taxing an environment. High humidity can really affect the filter life in a negative way.

Go to the grocery store and buy one of those newer plastic food containers that have the silicone gaskets. I have one big enough the whole half mask with the filters attached goes in. The plastic bag idea with filters never works out well.

Chris,
Do you have the battery one with filter you put on your belt or air from a compressor
with no filter? I can only find Versaflow with battery setup and not from compressor.

i have the one hooked up to my compressor
3m versaflo SA-100-PSK.

Ok found it. If using your shop compressor is there a special filter that keeps impurities out
of breathing tube?

i have 2 filters inline and a water separator.

Note that 3M now has a cartridge with an indicator to tell you when to replace it.
If you aren't going to use supplied air, it's definitely worth it

Info seems to be a little scarce on the supplied air systems. The one Chris uses is I believe called high
pressure system because he is using his shop compressor. I can't find enough info but I think the high pressure system requires quite a bit of cfm to operate it. The low pressure systems use a little compressor just for the breathing apparatus and nothing else. I've been on 3m website and a company called Allegro, Allegro sells complete system with the small compressor while it looks like 3m just sells
the mask, hoses, etc.

I use the Allegro half mask system. The compressor has held up well, but I have had to replace the straps on the mask a few times.

For the high pressure systems, you have a couple options.
1. They make portable boxes that provide everything you need. http://www.airsystems.com/index.php/2009-03-24-20-38-35/breather-box

2. You can go with a non-portable filter set.
http://www.airsystems.com/index.php/2009-03-24-20-38-35/air-panels

(these are just examples, 3m makes one, etc).

As someone else said, allegro (and others) make portable breathing pumps. These are just oilless rotary vane pumps from gast with the right set of filters and adapters (but, in my limited experience, you can't really get them cheaper from gast than allegro is selling them :P)

Allegro sells face masks that go with them, but they can also be made compatible with others.

For example, i found the allegro facemask to be a bit annoying. 3m makes a low pressure (and high pressure) breathing adapter for their half and full mask respirators.

rline-Back-Mounted-Adapter-Kit-SA-2000LP-Low-Pressure-1-EA-Case?N=5002385+3294780

(they have front mounted too)

These are attached where the cartridges normally go, in the same way.

I use an allegro pump with 3m masks and am quite happy with this set up.

For those that use the Allegro half mask system, or similar how do you deal with the hose?
I always found it to be the weak link of the system, heavy and not very flexible. It makes me feel like I'm on leash.
I would love to find one that allows me to attach it from the ceiling allowing easier movement around the spray room.

I cant stand using full masks tbh, they really get in the way.

I use a binks millennium 3000 with organic vapors cartridges and R95 particulate pre filters.

I use the cartridges till I begin to smell vapor and then change em out...2-3 months. pre filters I change out when they get dirty.

mask is light, comfy and have used em fpr 10 or so years

Richard,
You can use any hose you like, you just want to use things that ideally are rated for breathing air. They just give one that is cheap and effective (being rubber) :)

It also depends how much you are willing to spend.
You could easily just run a copper drop to the ceiling and suspend the hose from there.
You can also find plenty of very flexible scuba hose that is rated for breathing you can use (though sadly, miflex no longer does custom lengths).

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
