How Long Does A Gas Mask Filter Last?

The respirator is one of the most important personal protective equipment. It is very necessary for you when working in a polluted environment. It helps us avoid the harmful effects of toxic gases on the body. But not everyone knows how long a gas mask filter lasts.

Filter life ensures that respirators always perform to their full potential. In this article, we will answer this question for you.

How Long Does A Gas Mask Filter Last?

A gas mask filter will last up to 5 years when you have unopened it from the packaging. Once you’ve taken the filter out of its packaging to use, its lifespan is only 6 months.

However, when you work in a nuclear chemistry environment, the filter only lasts for 8 hours. This is an environment with an extremely high pollution index. You can only use the filter for a very short time to keep it as safe as possible.

When you have not used the Gas Mask Filter, the unopened packaging is where you store it. At this point, the filter will last up to 5 years from the date of manufacture. You can easily see this information on its packaging.

Once you’ve taken the filter out of its packaging to use, its lifespan is only 6 months. You must count from the date you open the packaging. 

However, 6 months is the life of the filter if you take care of it properly. Otherwise, the life of the gas mask filter may be less than 6 months, even a few hours.

Storing the filter in an airtight container or container is the best way to store it. This will help prevent contaminated air from coming into contact with the filter. Because polluted air can wear down the filter of the respirator. 

Filter life will depend on many factors. They are filter type, filter comb quality, frequency of use…

When should the Gas Mask Filter be Replaced?

In fact, respirators have a saturation filter. So you need to replace the gas mask filter periodically. The exact replacement time also depends on the contact time, storage conditions, chemical type, density of use….

In addition, there are also a few signs to let you know you need to replace another filter for your respirator.

  • When the gas mask filter makes it difficult to breathe or uncomfortable to wear.
  • When you have put on a respirator but still smell the toxic gas.
  • When you accidentally damage the filter.
  • When the filter’s shelf life has expired.
  • When the filter packaging is not intact for 6 months or more.
  • When it is time to change the filter.

However, you need to keep one thing in mind when working in a highly polluted environment. You must change the gas mask filter more often than usual. It’s best to replace it before you smell contamination.

For specific times, you should measure the pollution in the area where you work. If these are not clear, you should consult a colleague, manager or professional.

How to Store to Prolong the Use of the Gas Mask Filter?

Many respirators do not have protective attachments to prolong filter life. Therefore, the simple way to maintain it is to clean the dirt on the mask and filter. Then use a plastic bag or sealed container, until the next use.

The process of cleaning the gas mask filter is as follows:

Step 1: Clean your hands with soap

Hand hygiene is the most important step. But many people skip this step. You must make sure that during cleaning do not cause dirt to stick to the respirator and filter.

Step 2: Remove the filter from the mask

You need to disassemble the parts meticulously and carefully. Otherwise you may cause damage. Please read the instruction manual carefully for proper disassembly. Avoid damaging the filter during removal.

Step 3: Perform cleaning

After removing the filter, you will proceed to clean it. First, you dissolve some soap with water. Then soak the mask in it. Wait for a while and then gently wipe it with a towel. As for the filter part, check it for damage. If so, replace the filter immediately. Otherwise, gently wipe the filter with a sponge.

Step 4: Let dry

After wiping with a towel, you need to let the mask and filter dry. You just need to take a dry towel to wipe or leave in a cool place. Never dry using heat or exposure to sunlight.

Step 5: Reassemble

Once the respirator is dry, simply insert the filter. Note, it is necessary to check that you have installed it correctly.

Step 6: Preservation

After you finish cleaning, you need to store it according to the instructions. Because this will help ensure the life of the filter.

You need to store it in a cool and dry place. Putting it in an airtight container or a plastic bag is the best way. Never store it in humid places. Because of that you will damage the filter. To be sure how to preserve it, you need to consult the supplier.

Do Gas Masks Filter Viruses?

Bacteria or viruses are both airborne biological agents. They are particles of the air.

According to research by experts, the filter can filter at least 95% of airborne particles. There are even particles with the most penetrating dimensions. The virus itself is one of 95% of those particles, so the filter can completely filter it.

Do Gas Mask Filters also ‘Stop’ Smell?

The gas mask filter has the ability to block the smell of toxic gases from outside. Because when you wear a gas mask, the filter works to filter out even the most penetrating particles. However, you will still smell like rubber. That is the smell of the gas mask filter.

Some Notes When Using the Gas Mask filter

  • Should choose to buy the right type of filter suitable for the respirator you are using.
  • You need to install the filter according to the manufacturer’s instructions.
  • Regularly check the condition of the filter to promptly detect damage.
  • After use, you need to clean and store the filter properly.
  • Only order products from reputable suppliers to ensure quality and price.
