We’re in the midst of the worst global pandemic of our lifetimes, so we’ve all been learning a lot more than we ever wanted to know about personal protective equipment. We now all know you need high-quality face masks to protect against contracting and spreading COVID-19. The best in the business right now are Powecom KN95 masks and Nan Qi Xing KN95 masks, both of which are FDA-authorized and certified by NIOSH to work as well or even better than 3M N95 masks. We also all know that you need to carry Purell hand sanitizer with you at all times and clean surfaces with Clorox wipes, and Amazon has the best prices on the entire internet.

What some people still don’t realize, however, is that there’s one more thing everyone should have right now.

Since COVID-19 primarily attacks the lungs, a decrease in blood oxygen saturation is a telltale sign of a coronavirus infection. In fact, many experts say blood oxygen levels often drop even before any other coronavirus symptoms appear, and even in asymptomatic cases where no visible symptoms ever develop. But how do you know if your blood oxygen levels are dropping?

No, you don’t need to visit a hospital to check your blood oxygen saturation. All you need is a simple device like the popular Wellue 60F Fingertip Pulse Oximeter. Press the power button, pop it on your finger, and you’ll get a remarkably accurate reading in no time. According to the Mayo Clinic, normal readings should be between 94 and 100 — and anything below 90 is considered unhealthy, so call your doctor right away.

This particular model is a great value at $30, but a $10 discount and an extra $5 off when you check out with coupon code MSU4Z9S4 slash the price to an all-time low of just $15! The same brand also has a very popular smartphone-connected blood pressure cuff that sells for $100, but it’s just $48.99 with coupon code F3C8O9G2.
