Review on Enhanced 3M 6300 Respirator: Optimal Respiratory Protection with Advanced Features by Ashutosh Takumatla

My wife and I needed to remove ceramic tile grout from a wood subfloor. So we sealed the area to be treated with a 25 x 20 plastic sheet and let off steam with an angle grinder and a concrete attachment. INSTANT cloud of dust under the plastic! It was too easy to breathe normally on this ventilator and I spent a good hour there. I removed the ventilator outside and then returned to the house (no ventilator) to see if there was a difference. Holy shit I could TASTE the dust in the air. This respirator is definitely worth every penny, just make sure you get GOOD 3M filters (part number 60926). YOUR LUNGS THANK YOU LATER!
