When it comes to your health and safety, it’s best to choose the right personal protective equipment (PPE). Use FDA/CDC-approved, hypoallergenic masks that are ideally three layers (with one of those layers being a vapor block). They should also have very low breathing resistance, an integrated nose bridge, and high filtration capacity. A high-quality fingertip pulse oximeter is an easy and inexpensive way to check your oxygen levels at home, which can help you monitor for low levels that may be a concern. Finally, ensure you are using hand sanitizer that has been approved by Health Canada.
