 |  | When to change respirator filters?
< on 2/17/2007 5:29 AM >
|  | | | I just bought one today, and I am just curios about how long it will be before I will need to replace the filters. The packaging said that they should be replaced when the filters look dirty, or it becomes difficult to breathe through them, but I'm just curios about about how long that could be.

| | | | you should be the judge of that.
i dont think dirty would be a good indicator though. i know a friend picked up 2 respirators that some scrappers dropped,and they are fine,but dirty.
i think it would be best to replace them every X months?

|  | | | Typically, if you are using a particulate filter, you should change it once breathing gets a little little harder or you start to get a funny taste.
The filters that are used for gases, etc. should be changed each time you use it as the filter keeps drawing stuff out of the air that is nasty and gets saturated even if you aren't using it.

| | | | if you have charcoal filters, they are good for 30 hours when exposed to air. so always have a big ziplock bar to store them after, so they dont continuisly filter the air around it.

| | | | The charcoals should not be reused, and depending on the amount of toxins in the air such as solvents or toxic gases such as HSO4 may be used up in hours or even minutes. Remember charcoal can release what it stored; reusing it defeats the purpose.
HEAVY CONTAMINATED SITES SHOULD BE AVOIDED!!! These aren't a substitute for an airhood or a self contained breathing device! With insufficient oxygen or high levels of toxic gas(could be used to help make an emergency escaped, but not advisable!) these filters are useless. Remember many substances can also be absorbed directly through the skin, this includes PCBs.
If your not using them to filter chemicals, but particles, both types can and should be cleaned in the field by tapping out the dirt if it's extremely dusty. Careful use of a shop vac or oilless compressed air (blow or suck in the opposite direction of airflow!) will keep them clean and usable for a very long time if they're not contaminated with a long lived chemical toxin.
Make sure they are bone dry at all times when not in use; mold will grow on them!
