How to choose a mask: Hot topics and scientific guides across the Internet
Recently, as topics such as seasonal influenza and air pollution continue to heat up, how to choose a suitable mask has once again become the focus of public attention. This article combines popular discussions and authoritative data on the Internet in the past 10 days to provide you with a structured mask purchase guide.
1. Comparison of popular mask types
According to consumer feedback and expert advice, the current mainstream mask types and applicable scenarios are as follows:
| Mask type | Filtration efficiency | Applicable scenarios | shortcoming |
|---|---|---|---|
| medical surgical mask | ≥95% bacterial filtration | Daily protection, flu season | Weak ability to protect against particulate matter |
| N95/KN95 masks | ≥95% particulate matter filtration | High risk environments (e.g. hospitals) | Poor breathability and uncomfortable to wear for a long time |
| activated carbon mask | Absorbs odors and some particles | Air pollution, odor environment | Filtration efficiency is lower than N95 |
| Cloth mask/cotton mask | 30%-50% particle filtration | Daily dustproof and warm keeping | Limited protection |
2. 5 key indicators for purchasing masks
1.Filtration efficiency: Give priority to products marked with "BFE" (bacterial filtration efficiency) ≥95% or "PFE" (particle filtration efficiency) ≥95%. 2.fit: The mask should cover the mouth, nose and chin tightly without air leakage on the sides. 3.Breathability: Especially children or those who need to wear it for a long time, need to pay attention to the breathing resistance (such as N95 masks with high resistance). 4.Certification standards: Check whether it has passed national standards (such as GB 19083-2010) or international certification (such as FDA/CE). 5.Timeliness: Disposable masks are recommended to be replaced every 4-6 hours, and replaced immediately when wet or contaminated.
3. Answers to recent hot questions
Q: How to choose children’s masks?A: You need to choose a small-sized mask specially designed for children and ensure that it meets the GB/T 38880-2020 standard to avoid the risk of suffocation caused by adult masks.
Q: Can the mask be reused?A: Both medical surgical masks and N95 masks are disposable designs, but N95 can be reused briefly (no more than 5 times) under pollution-free, dry conditions.
Q: How to distinguish real and fake masks?A: Purchase through official channels, check the production license number on the packaging (such as the words "X Machinery Notification"), and scan the anti-counterfeiting code for verification.

The choice of masks needs to be based on specific needs: surgical masks are preferred for daily protection, N95/KN95 are selected for high-risk environments, and cloth masks are only suitable for low-risk scenarios. Pay attention to authoritative certification, fit and comfort, and avoid buying three-no products. Special groups (such as children, patients with respiratory diseases) should choose under the guidance of a doctor.
