If they use RO it's sterile. Pore size on an RO filter is smaller than the diameter of viral particles. Standard RO purification is used for injectable products from pharma.

Ion exchange is much different than RO and should not be lumped in together. Perhaps you are confusing purified water with deionized water? DI water is different than purified and you generally use DI water for chemical experiments. DI water is achieved after passing water across ion exchange resins and does not actually say anything about the purification.

Bottom line - RO is generally considered more sterile than heat distilled. DI is not RO, but water can be both purified and then deionized if necessary.

Been dealing with sinus congestion and headaches for about 4 days. In the midst of a bad headache I took off to Walgreens to get one of those plastic bottles that come with the salt packets so I could flush my sinuses. Used to have one but, I can’t find it.

So I squirted about 1/3 of a cup up each side. I’ve used them before so I knew I’d have vertigo for a few minutes afterwards. I felt like I was in the matrix. Seems I was rotating on a least 4 axis at the same time. I grabbed the countertop and hung on for what felt like an eternity when in reality it was a minute or so. But, my headache is gone so it was worth the magic carpet ride.
