 DURATION OF FILTERS

Duration time for filters depends on the pollution level and the frequency of usage. 
Generally speaking, to protect yourself from pollution or any airborne contaminant, we recommend to replace your filter every 2-3 days (if you are using it for several hours a day) or 18-24 hours of total use.
If you use it in a particularly dusty environment (eg. doing woodworking, gardening, etc) would be better to replace your mask with a new filter after you finish that activity.

✅ CURIOSITY: How do activated carbon filters trap pollutants?

Carbon air filters remove pollutants from the air with a process known as adsorption. Note that this is different from absorption. In absorption, the substance you want to remove (let’s say water) is absorbed into the structure of the absorbent (like a sponge), but it doesn’t become a part of the absorbent on a molecular level. Therefore, when you absorb water with a sponge, the water does not become chemically bonded to the sponge. It just fills in the spaces inside it.

Carbon filters on the other hand use ad-sorption, not ab-sorption. The key difference here is that during adsorption the pollutants stick to the outside of the carbon. Whereas with absorption, the pollutants are absorbed inside the structure itself–as with the sponge.

Carbon is a lattice of carbon atoms connected to each other. When a molecule of some airborne substance comes through the carbon, it can stick to the surface of the bed. The process of adsorption allows carbon air filters to filter organic chemicals and pollutants from the air.

The problem with the activated carbon bed is that over time, the gaseous pollutants increasingly fill up the adsorption sites of the activated carbon. Once the bed is saturated, the filter can no longer trap pollutants. So, as conditions change, different chemicals may be released from the filter. When a carbon air filter is saturated, you might notice it giving off a strange odor. This is a strong indicator that it’s time to change your carbon filter.

Very satisfied!

Ordered Mask, and Filters...order was filled promptly and delivery was amazingly fast. I’ve been wearing my mask daily and am very satisfied with quality and fit! I need more as I wear this mask every day due to my unfortunate exposure to the general public and the many who refuse to protect others! I truly believe I wear this mask to protect myself as well as others!! Will be placing another order soon! Thank you for a great product!

Quality USA product

I bought sport masks on another store & bought the Airnex replacement filters online also.
Comparing the cheap China junk to the USA Airnex quality is no comparison.
The stitching alone is quality.
I would recommend these filters to any American
Airnex keep up the good work & keep pumping out the gear

Excellent!

I'm a city bus operator and during these times at work a good mask can save your life. I purchased these mask due to the fact that most of my coworkers wear similar type so I decided to try them out. I made a purchase on Wal@@@@ website from the same company so instead of using a middle man I went straight to the source and what a difference in price and shipping. The quality of this mask is excellent also doesn't fogg up your glasses while wearing. I purchased two mask a 2 dozen carbon replacement filters. I will be making another purchase from Airnex in the near future. Ordered
