OxiClear N99 Replacement Carbon Filters – Pack of 20

Keep Your OxiClear Mask Working Properly

OxiClear N99 Replacement Carbon Filters – Pack of 20 are made for OxiClear reusable N99 anti-pollution masks. The mask body is reusable, but the filter is the part that handles daily pollution exposure — so replacing it regularly helps maintain cleaner airflow and better performance.

• Pack of 20 genuine OxiClear filters: Built for use with compatible OxiClear N99 reusable pollution masks.
• Activated carbon filtration: Helps reduce exposure to PM2.5, dust, smoke, vehicle exhaust, odors, and common urban air pollutants.
• Essential for daily use: Ideal for bike riders, commuters, outdoor workers, school runs, travel, and heavy pollution days.
• Better long-term value: Keep the reusable mask body and replace only the filter instead of buying a new mask every time.
• Smart add-on: Best paired with OxiClear N99 masks, the Starter Kit, or the Family Protection Kit.

Need a Mask Too?

If you are buying filters and also need a mask, choose the OxiClear N99 Starter Kit. It includes the black N99 mask with valve plus this Pack of 20 replacement filters.

Buying for adults and kids together? Choose the OxiClear Family Protection Kit.

When Should You Replace the Filter?

Replace the filter based on use and pollution exposure. Change it sooner if you notice visible dirt, odor buildup, increased breathing resistance, moisture, or if you have used the mask heavily in dust, traffic, smoke, or smog.

Pro Tip

Add this filter pack with your mask order. It is easier to keep spare filters ready than to wait until your current filter is dirty, clogged, or uncomfortable to breathe through.
