Wow that's about $300.00 in disposable masks for each person for one project. The filters on my 3M last for a loooooong time before they need changing and I have about a third of what you spent invested in my full face that has been used on multiple jobs not just one. Plus with a simple switch of the filters I can work with acids, bleach and other noxious gasses. In fact I was just using some acids in the engine compartment the other day and never smelled a thing even in a tightly confined space...

Two months at $5.00 per day, by your own admission, would have bought a full face respirator for three people for the price of just one persons disposables. Am I missing something or has you lost his penny pinching edge..?
Would still need new cartridges and what do they cost?Exactly what I was thinking...
safty gear is usually the employers responsability and the cost should be included in the contract price under tools and supplies or in cost plus materials to the customer unless you can negoitate a deal with the employee and get a hold harmless agreement signed by the employee stating that he or she has wave the required saftey gear and will supply his or her own...then hope and pray that they have no injuries while working for you sort term or long term...the best way to cover your bohonkus is the furnish the gear and requir them to are it ....
Very misleading. The lifetime of a cartridge or filter is a function of only one thing - the load. A high concentration environment will create a much higher load thereby shortening the effective duration it is effective. Don't ever equate efficacy with time. The actual "break-through" time can be measured in seconds under extreme condition. Regardless of what anyone say suggest, when using a respirator, always be mindful of what your nose tells you.
Don, Very well said! there were short periods when the dust was do thick coming from the dumping chute to the dumpster that local farmers stopped to check for fire. The debris consisted of sand, plaster dust, paint chips, and wild animal feces accumulated during the 35 years that the building was unoccupied and open. barn swallows had nested in the same places for long enough that some of the nests were a foot tall and the pile of guano on the floor was also as big.
