Respiratory Protection

Below we have listed the most common forms of respiratory protection available to the general public, with the pros and cons of each.  The description matches the picture to the left or right, not below or above.

	This type of dust mask is the least expensive. You can buy a pack of them for $2.  They offer very little protection for your lungs, but are better than nothing.  The nose clip will often fall off and the single strap virtually guarantees leaks.  This type of mask may stop the largest glass fibers from being inhaled and may reduce the incidence of throat, mouth and nose irritation.  They should only be used by people with one-time or infrequent contact with fiberglass insulation.
This type of dust mask is significantly better than the one above.  The two straps give a much more snug fit, and the filter medium is thicker.  These are available on the web and in many industrial supply outlets. They should cost only $2-$3 each when purchased in a pack.  Some sites are trying to sell these for $8 and up each.  Don't be fooled.  You can throw these in the washing machine and use them over.  Great for general yard work and the homeowner who occasionally needs protection against fiberglass insulation.
	This is an example of a half-face respirator.  There are many brands, but they all work about the same.  The cartridges are replaceable and color coded for target pollutants.  HEPA cartridges are the best for fiberglass, but almost any cartridge is better than a dust mask.  The full headgear guarantees a snug fit.  These should cost less than $30; the cartridge prices vary.  This is the minimum level of protection necessary for homeowners and tradespersons who have regular contact with fiberglass insulation.
This is an example of a full face respirator.  The main difference is the face shield.  They use the same color-coded cartridges as the half-face models.  Workers with daily fiberglass contact should strongly consider the purchase and regular use of a full-face respirator.  Prices start at about $60 and go up.

Any respiratory protection needs to make a good seal against the face in order to be effective.  Facial hair makes a good seal difficult or impossible.  Half- and full-face respirators make the lungs work a little harder; therefore, it is wise to occasionally take a break from using a respirator, especially in hot conditions.
