How often does one have to change the mask?

N95 masks are technically single use masks. You should dispose of it after you take it off your face.

We bought the masks specifically for travel in China (Beijing) where the smog is awful, and i wore one mask for the 3 days we were there with no problems. I would probably say 5 days itf used for smog but from dust and dirt that depends on the job and the length of time and i've not used for this work as yet.

I find that we change the mask on average once a week not because of the fact that it gets filled with pollution, but that my kids tend to drop them, squished them, etc. My guess is that if you take care of it you can use it for 2-3 weeks if the air is not too bad.

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

I am not a professional but I would change mine everyday because of the germs on the outside of the mask, they could transfer to other places and things. I hope this might help you.

I usually change them about once a month. I rinse them off when I change the fountain once a week. Sometimes I get longer.

The filter can be changed either 6 months or a year, but you must remove the front panel and vacuum off any debris about every 2 months, depending on how dirty it gets will determine how often you have to do this.

I change mine every 6 months. I have pets. You may be able to go longer if you don't have pets.

Vogmask N95's are reusable for 2-5 months depending on the environmental conditions. In severe air quality index, the mask should be replaced after 80 hours of wearing (2 months at average 2 hours per day), in less hazardous environment, the mask will filter efficiently for up to 5 months. There is an AQI chart and useful life recommendation on the back of the packaging. The filtering capability will decline when the pores of the filter layer clog with particles, and breathing resistance increase is noticed. Hope this helps. Thank you.

I would think changing it would not be an issue for quite a while. I only use it once per month. The current filter should stay good for a long time at that usage rate. When the time comes, I will rinse the filter and put back in for as long as I can.

On the old models I changed every 30 days. This one, with filter A, says it will last 3-6 months. I haven't had this one long enough to know for sure.

Daily if you want to, but we recommend every other day. You will have residue left from the mask after each application and the clay mask effects can actually last up to 24 hours after your application.

Yes, I do, and have for over a year. A cool feature: if you forget to put your mask in, It won't turn on.

The suggested replacement rate is every six months, but I replace it every three. Using the special covers that supposedly clean the brush while not in use, I find that black spots appear in the brush head if I don't switch it out after about 3 months.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

think it has more than most here say; probably closer to 30 applications. it doesn't need to go on thick, just enough to cover. love this mask and use it two to three times a week.

Hi, I am sorry, there are 15 different masks in a pack. We cannot change the packs. Thanks, Terry
