How often should you replace the filter in your face mask?



Here's what you need to know about your filter.

With face masks becoming the new norm around Australia and the rest of the world, you've got to know how to properly use it. And we don't just mean how to put it on.

Some reusable face masks come with filter inserts that can be worn inside your mask for an added layer of protection. Alternatively, you can opt for a mask that has built-in filters, usually known as P2, N95 or KN95 masks.

These filters need attention; they need to be changed and replaced, especially as you wash your mask.

How often should you replace the filter?

As a general rule of thumb, filters can be used up to seven times. However, this will also depend on how often you wash your mask, as these filters cannot be cleaned.

Always follow the guidelines from your mask's supplier, as requirements differ. Sticking to those rules will maximise your mask's effectiveness.

Do you need to use a filter?

While a filter doesn't guarantee 100% protection, it certainly does help, according to the recent research. Incorporating an extra layer doesn't hurt!

This is especially true if you decide to go for a reusable face mask. While they are usually cheaper, you'll still want to consider investing in a filter. Why? Well, a recent medical research study suggests that 3-layer masks are the most effective in helping contain the spread of coronavirus.

Where to buy face mask filters online

Most face mask suppliers on the market, like Breathe Easy Australia and Clear Collective, will also sell bulk packets of the filters. You can also check out online marketplaces like Kogan and Amazon.
