In a sick room setting, how long can one expect this mask to filter before it needs to be changed?

I can't tell which mask you mean from this format, but the two types I bought on Amazon state that they are basically for particulates instead of gas/mold spores/asbestos. They have built-in respirators to let air in however, so probably wouldn't do for a sick room. I have bought the little masks that are for medical situations, though, and those are to be used just once.

I didn't use mine long enough to need a filter change. But from experience with other humidifiers, you should change the filter when it becomes discolored. The filter is you wick for moving the water to the top. When you notice a change in the amount of steam, the wick is no longer effective.

filter doesnt need a change for very long time, it needs cleaning/with vaccum cleaner only. thats whats HEPA FILTER, REPLACEMENT filters also available in Amazon.com

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.

Approx. every six to eight months, running it 8 hours a day in my bedroom. I live in the southwest, in a dry dusty environment, so it would probably last longer under less severe conditions. Also, I must clean the pre-filter at least once a week.

I have only used it for about 6 weeks. Every other week I took out the filter and put it in a diluted vinegar solution over night. I hope that the filter will be cleaned and lasts a little longer.

Not everyday. Mostly I only wear for a short while. I only change it when the mask is visibly dirty and that can mean days.

It wouldn't hurt....with my filter the product it cleans it so well the filter absorbs a lot of dirt/debris, I've waited longer -up to even a week, and then it really needs replaced. I think a lot depends on the type of filter system. I use a Whisper Filter system.

This is a filter for an IQ Health Pro air purifier. We use our's in our great room which is a combination living room/dining room. It is also open to our kitchen. We've had one of these units for 13 years. We never placed this unit in our bedroom though I'm sure you could use it there as long as you keep the setting low to keep the operating noise to a minimum.

First of all the cleaner the filter, the faster it filters. When it is new, it will filter the full amount in about 6 hours. After the filter gets some use, it will take a bit longer. I take mine out and wash them every 3-4 months and change them once a year.

The directions for the platinum model say the filter should be changed every two to four weeks. It also says you can thoroughly rinse the filter and put it back in. I've had no problems with doing that.

I have used the same mask several times when I've worn for a short period (I keep it on a ziploc bag). Otherwise, I would use it once if worn all day. You can also tell if they get dirty. Hope this helps.

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.

Filter needs to be changed every 6 months or so - but realistically, I haven't done that yet and it seems to still work well. I run the machine on automatic every morning.

There is a filter element on each side of the filter that can be replaced if they are dirty, Check for filter replacements using the 3m mask number.

I don't know if there is a set time for changing filters. I began to notice that, even after cleaning my filters, there was a particular odor when I used my vacuum. I ordered and changed my filters and now my vacuum works more efficiently and the odor is gone.

Get some Caffezia and let the filter and column soak for a couple of hours.You can't see inside but everything will be clean & shiny.
