All-day protection, every day – Whether you're working, traveling, or enjoying the outdoors, the O2 nasal filter mask is an invisible shield against airborne particles. Ideal for environments with high pollen concentrations, smog or heavy pollution, wildfire smoke, dusty work conditions, and crowded areas.
3M Advanced Filtration Technology – Designed with premium 3M filter materials, these expandable nasal masks use electrostatic technology to trap ultrafine particles as small as 2.5 microns – helping you breathe cleaner, fresher air.
Comfortable & Latex-Free Design – Unlike traditional face masks, O2 nasal filter masks don't cause heat buildup, sweating, or fogging of glasses. They're discreet, lightweight, and ideal for use at airports, public transport, and crowded indoor areas.
Breathe Easier with Allergy Relief – Say goodbye to seasonal sneezing and nasal congestion. The O2 nasal filter mask helps block airborne allergens like pollen, dust, and pet dander before they enter your body – providing natural, drug-free relief wherever you go. Allergy UK approved.
Find the perfect fit – Made from soft, surgical-grade plastic, our nasal filters come in five sizes to fit most nose shapes. Start with our convenient 4-size trial pack to find the perfect fit for you. Replace the nasal filter every 8 hours.
