Customer Reviews
Mask for wildfire smoke
I grabbed a N99 Respirator when the wildfire smoke was bad last year. It helped a lot, could actually breathe outdoors. Easy to order, and it came quicker than I thought. Pretty happy with it.
Detailed Look at My Cambridge Mask Order
I ordered a Large PRO Mask, solid black, along with a pack of Filter Refills and a Head Strap. The website was easy to navigate; I used their sizing guide which suggested 'Large' for me, and it fit perfectly. Confirmation email arrived promptly after purchase. Shipping took about 6 business days to arrive in New York, which was within the estimated timeframe. The packaging was secure, and everything arrived undamaged. The mask quality is noticeable; the material feels durable, and the adjustable ear loops are a plus. I also appreciated the included instructions on how to properly fit and care for the mask. Customer service was responsive to a question I had about washing the outer shell before my purchase, replying within 24 hours. The Head Strap makes it even more secure for extended wear.
Good Mask, Shipping a Bit Slow
I bought a PRO Mask, size Medium, from them. The mask itself feels very high quality and is comfortable to wear, which is important for my daily commute. The filtration seems effective. However, it took 8 days to reach me in Texas, which felt a little long. I also wish they had clearer guidance on filter replacement intervals.

quick question for anyone who's ordered before, how long does shipping usually take to, say, California? Need one before a trip.
Hey, thinking of getting a PRO mask but worried about sizing. How do you figure out what size to get for these?
Can you actually use two discount codes at checkout? Got a student discount and also found a 10% off code, curious if they stack.
Does anyone know if these masks are actually N95 certified here in the US? Or are they just 'N95 equivalent' or something?
